Hoping that someone here can help, or point me to a better forum for this type of problem. I'm starting here since my device is the i717.
I have the Galaxy Note i717. It has been rooted and running various roms over the past year. I have had no problems with my cell service, data or voice, in all that time. No wifi problems either. A few months ago, when Jelly Bean was released for the i717, I flashed it, completely stock, but still rooted. Worked great for me without any issues until a week ago.
So, I went on vacation, and everything worked great there, including wifi. I came back to work, and noticed that I did not have data service in our building. I did have voice/sms service though. Voice & SMS were tested and verified to be working. I rebooted the phone without luck. Cycled Airplane mode without luck. Pulled battery without luck. Turned data off, then rebooted, and turned it back on without luck. Needless to say, I have read about every hint I could find for data connection problems, and think I have tried them all.
Our office has an AT&T installed repeater system (not one of those little ones that you put in your house, but a true repeater, with equipment in our communication room, and with an antenna on the roof that connects with the main AT&T tower a few miles up the road. Antenna up the road is 4G-LTE, but our repeater is only HSPA+). In 3 years being in this building, I have not had any previous problems with my cellular connection through the repeater.
I went to lunch, and as soon as I left the building, emails started coming in. I had 4G-LTE again. Went back in building, and lost the mobile data connection again. I talked to a few other people in the building with AT&T phones (none have an i717), and they were working fine from the repeater.
Next, I re-flashed the phone with the stock ROM, still rooted and custom recovery, and still no luck. I flashed an old backup I had from when I ran ICS, no luck.
Now it was time for desperate measures. We rebooted the repeater antenna in our building, and still no luck. We have talked to AT&T, and of course, they are no help, and we can't get a tech to at least attempt to find out why only my phone has problems with their repeater.
Next, I got more desperate. I did a complete factory wipe/restore of my phone with odin, all the way back to the day like I took it out of the box. No root, no custom recovery. Still has the same problem with the repeater.
Now, I'm starting to think my phone is broke, except for the fact that I leave the building, and instantly connect up with the 4G-LTE tower. When I drive home, I have a few areas I go through that are only HSPA+, and I connect to those fine. It seems to only be a problem with the repeater here, but I don't understand why the other AT&T phones are able to connect without any problems.
I have tried 5 or 6 different modems (UCMD3, UVLG3, UCLF6, etc.).
My APN is the same as it always has been, but I did find a few others and tried them, and even though they worked outside the building, I would lose the mobile data connection as soon as I came in the building.
I also got with our companies "phone person", and they even set me up with a new SIM card, just in case something was flaking out on the original card, but no luck there either.
We have calls in with AT&T, but it has been a few days, and we can't be sure they are going to get a tech person to help or not. From the sounds of it, I won't count on it.
We do have wifi in the office, but it is restricted, so I generally do not connect to it, and just stay on my mobile connection for everything. But even if I do connect to the office wifi, I can't receive MMS messages, because they seem to only come in on the mobile data connection, even if wifi is connected to the internet. I tested this a couple of times, and I could not get my MMS until I went outside and connected to the tower 4G-LTE service, then they came right in.
So...what kind of help or direction can any of you give me? I'm up for suggestions, and will be happy to clarify any of the above.
I ran a log report (had a hell of a time figuring out how to get the logs from a JB phone, but found that CatLog is able to do it now). I was not able to interpret what I was seeing in the logs, but if someone knows how to read them, I can see if I can export them from CatLog, just let me know that you feel you can understand it, and I will send it to you.
I ran CatLog recording while the phone was without a mobile data connection, then cycled airplane mode, and watched it attempt to do a data connect and fail. That is when I stopped the log, so it should just be showing that info for the most part. I'm just wondering if the log shows something that I could throw at AT&T to get them to come look at the problem more.
Thanks everyone. Sorry such a long post, but I want to give as much detail as I could.

Turn off the repeater.

I'm on Vodafone UK, at some point this afternoon lost my signal, just had the no signal icon when I checked my phone.
I didn't change any settings, it was working fine received a couple texts, went to reply later and had no signal.
1st I tried going to settings->wireless settings and switching phone off and back on, no joy.
2nd tried Switching phone off and on, no joy
3rd tried settings->menu->all setting->personal->phone->network change network selection to maual, then select vodafone UK from list, still no joy
4th put network selection back to automatic, no joy.
5th turned data connection off no joy
Put my sim in girlfriends unlocked Nokia worked fine and I could make a call.
Returned sim to my phone.
I have noticed it will stay on no signal for ages, then will be trying to find a signal, will appear to have found just a phone signal (full strength) but attempting to make a call will just sit on the dialling screen for ages but never connect and then gives up without an error message after about 40 seconds. My data connection is off when it finds a signal, if I switch it back on it seems to be trying to connect GPRS then after a while back to no signal. Leaving it alone when it appears to have found a signal it stays for anywhere between a few seconds and minutes before going back to no signal.
Sorry my post isn't easier to read, been up since 4am getting tired now, and my phone is doing my head in.
Just to stress again my phone went from working to not just sitting on the table no settings changed or anything. Please help
I had a similar problem to this after flashing a ROM. My signal will be ok for an hour or 2 then disappear, never to return. If I switch 3G off it seems to solve it for me.
Me too
Xenton, I'm on VF UK with 1.72 ROM, and also have random signal drop outs. It happens even when static in the rear part of my house where I can see for 30+ miles and must have line of sight to multiple masts. The coverage maps on VF's website say the phone should be getting good signal, but sometimes, as you say it drops out, to return soon, later, or (but only very occasionally) not at all. I hard reset my phone a short time ago, so I'm pretty sure it's down to the ROM/radio. I've the feeling it's something we just have to live with, unless we wait (forever?) for the VF UK 3.14 ROM or install the WWE version.

Hi,
Thanks for the reply. At work this morning my phone was working fine, then when I returned home same problems, no resets or changing to settings. All this makes me think it is a problem with VF, I have posted on the eforum but this is my second day without a reliable signal at home now after 2 years faultless coverage at home. If it keeps up, I may have to drive to a signal and call VF. Did you get your phone through VF, if so you should get onto them for a replacement or repair if it is your phone.
One other curious thing today at work I got some txts from VF which automatically change setting for mobile internet and picture messaging. They still worked fine at work, but I hadn't requested the settings be sent and the old ones worked fine, but then so do these new ones, just not at home, where I am mostly signal-less.
Xenton,
I used to be unable to send MMS's until I hard reset my phone. Oh, and despite requesting the MMS settings via the customer services and the VF web site, nothing ever arrived on any of the occasions it was supposed to.
I'm out of my initial contract after a year, so think I'll do well to get a new hand set. It's more of a relatively minor annoyance, as opposed to what seems like your more significant issue.
It only really happens a noticeable amount at home, so I’d put it down to something to do with the number of cells my phone could presumably see, and perhaps it getting ‘confused’ (?).
I’d be interested to hear what you find out on this, if you reach a resolution/find a solution.

In the past two weeks, my mobile data has been down. I don't believe it to be an outage in my area due to the duration of the problem, and the inconsistency with other Verizon Wireless phones. I was running Juice Defender for a while, and every now and then I would notice that the Mobile Network would drop. Toggling the Mobile Network would not fix the problem, either. I usually cleaned out my cached data for the Juice Defender app, turned the app off, then toggled airplane mode once. (Sometimes just toggling Airplane Mode wouldn't fix it, therefore I had to clear the cache for the app.) Now this fails to work. I cannot get my mobile network to connect by any conventional means. When I receive MMS messages, my network will connect long enough to download the attachment. Also when I do a search for a Software Update, it connects just long enough to tell me there aren't any updates for my phone. I've tried updating my PRL with *228 and I've even tried *18 from a post over at Droid Forums. Neither work. I've removed the battery and SIM Card as suggested in some other threads here at XDA. I've also removed the Juice Defender app.
The phone is not rooted and has never been rooted with the Temp Root methods. I'm not opposed to rooting, but if I root, I'm gonna perm root and I would rather not have to factory reset my phone if I don't have to right now. I'm mainly posting this because I cannot find anyone online with the same issue that I am having. Any help would be appreciated. Personally, I think its an issue with Dalvik-VM. I can attach a copy of my LogCat if needed. Any ideas on my issue? Thanks in advance!
Check your power settings, if you are in economy mode it will mess with your data connection.
I have a paid version of JuiceDefender, it has caused me so many problems I don't even bother to install it anymore.

I also have the same issue, tried a couple basebands and could not fix it. I ended up not using it...
Every once in a while my mobile network or just lte somehow gets turned off and I have to turn it back on, but that's rare.
I tried juIce Defender and also had problems losing my connection so I uninstalled it. Plus the settings were so confusing to me. I'm using Green Power now and that seems fine.
You didn't mention mhs so I assume you're not using it but that has known connection issues.

Did you ever try doing a factory reset? I'm curious to know if that will fix it.

Juice Defender gave me fits, too. I'm not using my phone as a Mobile Hotspot, either.
I kinda think its my ROM. I'll play around with some stuff, or I'll just get around to doing a factory reset and see if that fixes the problem. I'll post any solutions here for others.
Are you in a good 4g area? If you scroll down the general section here, you will find my topic. If you use 3g more than 4g, there is a post in that thread about##778#. It helped me. Sorry if it doesn't help you, Cheers.

I just wanted to let you know that I'm having this problem as well. I AM rooted and running CleanRom, but my daughter has a non rooted Bionic, and both of us suffered a complete loss of data today. My husband's rooted Rezound is fine.
I took my phone into Verizon today, and after initially just trying to swap out the phone (which I wouldn't allow them to do, it took me too long to get my phone the way I want it), they finally switched out the 4G sim card, and the data came back instantly.
When my daughter leaves school today, she will get her 4G card swapped out as well, and we'll see if it is in fact a network connectivity problem.
It seems to me that our 4G phones has a lot of trouble switching from wifi to 3G/4G service.

I will +1 this. My work WiFi is spotty, and so the phone falls in and out of WiFi. The Rezound HATES that and usually leaves me with no connectivity. There is definitely a WiFi->Mobile Network issue.
Try doing a factory reset. Could be a bad device... Im getting amazing reception on mine. I havent even seen my 3G or 1x icons yet. Constant 4G lock.
Forget what I said, my data connection has been dropped again for the past thirty minutes and there's no way for me to get it back.
I'm going to try a factory reset. I *really* don't want to have to send my phone back because my husband is getting amazing coverage on his Rezound. However, we're still in the first week of our Verizon contract, and if this looks like it will be a standing issue, then we'll have to cancel and go crawling back to horrible Sprint.

I think I'm going to try doing this. How painful was it for you to convince them to give you another SIM Card?
Edit: Just read your last post. Please let me know what a factory reset does for you.
They had no issues at all swapping out my 4G card, they certainly couldn't let me walk out of the store with no signal. They knew they had to try something.
The factory reset on the phone appeared to work. I've been steadily switching it from wifi to data, and the data signal picks up, albeit a tad bit slow. Only thing is, I still don't really get 4g, while my husband's Rezound has a great signal.
I got insurance on the phone, so I'll put up with it as long as I can before I start screaming at Verizon.
Good to hear. I'm going to try to switch out my SIM card today and see if that fixes it. I thought maybe it was something with the ROM, seeing as how my 3G will turn on whenever I need to send an MMS message, so a factory reset made sense to me. I just don't want to do it. Lol. Thanks for the info!
I've experienced it twice in the last 24hrs and it just happened to be right after I installed and used LTE OnOff. Don't know if there might be a connection there. I keep forgetting this phone has the ability to switch 4g/3G unlike the TBolt. Needless to say, that app is no longer on the phone.
KORM via the beast known as the Rezound.
I had an issue with the mobile network just dropping in and out (other people in the room did not lose signal). We currently don't have 4G and it is 3G only. I did a factory reset of the phone, but it continued to occur. Took the phone back to Verizon store to exchange it (it was 1 week old). At first they weren't going to and gave me a run around but in the end exchanged it. Have had no problems with new phone.
My girlfriend's Bionic keeps dropping 4G more frequently than my Rezound. I get this problem too though. Usually a toggle of Airplane Mode fixes it...but it's pretty damn annoying. Happens once or twice a day!
A Factory Reset fixed it. Everything went smoothly, too. I backed up all my SMS Messages with HTC's Messaging app, and got my network back as soon as I restored it and set everything back up. Hopefully this will help anyone else who might have had the same problem.
I've been side by side with a fresh Rezound and watched both of them jump from 4g to 1x to 3g and sometimes never 3g. The problems were a million times worse with my droid charge as it's a combination of the handsets and the towers.

Hmmm
I have this happen if I am in an area with NO signal (such as the basement level of my office building) for long time. Only a reboot will bring back data. Does not happen often (maybe 2ce in a month and a half).
I am intrigued by the person who blames the install of LTEOnOff. I have it installed but do not use it. Maybe if I ever have to hard reset (such as if ever run the unlock), I will not reinstall that program.
4 day old, brand new phone, stock ROM, un-rooted.
Left the wi-fi zone of my house this morning. Phone jumped to 4G, as expected. At destination, hopped on that wi-fi. Left to come home, phone jumped to 4G. Checked location of a caller via google maps. At home, phone jumped onto my wi-fi. Got back in my car a few minutes later to go meet with the caller. Noticed that the map wasn't working (or so I thought). Went to the caller's record to view address on map. Nothing happened. Then, I noticed no mobile data network. Although I hadn't changed any settings at any time up until that point today, I checked every setting I could think of, anyway. Still no mobile data connection. Restarted the phone, back to normal. Figured it was just "one of those things".
Came back home after meeting with the caller. Phone jumped back onto my wi-fi. Several hours later, I left the house. Again, phone could not find mobile data network. Called carrier tech support (what choice did I have?). While on a different phone with the tech, after trying everything the tech suggested, finally restarted the phone while at home. Phone saw my wi-fi. Went down the block of my house, phone jumped onto 4G. Turned around, came back home, phone jumped on my wi-fi. Repeated 4 times, no failure.
Sat down at home, still on the phone with the tech. Manually turned off wi-fi, phone jumped on 4G. Turned wi-fi back on, phone jumped onto my wi-fi. Repeated this 4 times. On the 4th time, jump to mobile data network failed again. The only way to get back on mobile data network is to restart. What a PITA!
No choice at this point but to have another phone and sim card shipped from carrier, which the tech had no problem doing.
Has anyone ever experienced anything like this? If so, did you ever find the cause, or could I really have a bad something-or-other? Or, is that just the way this phone is? If so, I'm going to be PO'd that I bought this phone, you know what I mean?
Curious issue with my Titan II. Cellular data connection just fails at random intervals. Cycling airplane mode or rebooting the phone is the only way to get it back. HTC blames it on AT&T and AT&T blames it on HTC. I've spent hours on the phone with each. Even got a new Titan II from AT&T, but it went into this constant reboot loop, so I went back to the first unit.
Now comes the interesting part: I live in Detroit and have been traveling to FL quite a bit, this year.. and the issue DOES NOT HAPPEN IN TAMPA. Phone runs perfectly well, there. Here in Detroit, cellular data "up" time ranges from 5 minutes to 14 hours when static. 2 minutes to 20 minutes when driving around town. Drops are less frequent when streaming something.
HTC Titan II stock (FW: 2180.0400.118011.502)
Windows Phone 7.5 (7.10.8112.7)
4G SIM card (3rd one)
Appropriate data plan
Serious thanks for any ideas anyone has. Do I add an APN, throw the phone against the wall, or what? Please do not suggest I change to a different phone as that is not an option.

Yes, I'm facing the same issue.
It seems something related to wifi sleeping when the phone goes stand by and the solution could be keeping it alive in some way....like streaming..
I hope this will be fixed with AT&T Tango 8773 Update (Once it finally come....)

Are you sure you aren't hitting "black spots" on your network? If you have random connection drops in only particular area it is likely the masts and AT&T issue. I've swapped my provider from the one which did 2G/3G signals to 3G only provider. 3G only has better coverage and lesser black spots on the network and hence I hardly see any drops in connectivity. Don't hard reset or anything, it will only make you re-do the whole phone, won't help the cause.
Have you checked if two golden pins on the back cover are making good contact with phone?

Have to rule all of that out as it doesn't happen at all in Tampa. I can drive from Ybor City to Clearwater and back and never need to reset the phone. Here at home, I have four bars and will lose cellular data with the phone in a static location. Driving around in Detroit is guaranteed to make it drop cellular data even with the phone lit up and active. I can have Navigator running and it'll just quit loading maps and giving directions until I cycle Airplane Mode. In Tampa, this doesn't happen.
In Tampa, I've gone the whole week without any need to reset the phone. I can't walk from the gate to baggage claim in Detroit before it loses its data connection.

UPDATE: Cellular data connection is a little better with WiFi turned off. It won't lose it as quickly in a static location, but still loses it as I move between towers. Also had to reinstall a couple of apps that had stopped launching.
Is forcing Tango an option?
I have the same problem,
I live north of detroit.
my phone has been in to htc repair 3 times, i think they have replaced every part in it, the last time i got it back it held connectivity for 11 minutes.
this is on my home tower as well as several towers around me.
Normally all testing was done with wifi off, on towers where the lumia 900 and my wifes iphone have never lost data.
i have been waiting a week for a htc level 2 rep to call me.
we shall see
Keep me posted. Last time I spent time with HTC, they decided that - since the issue only happens in Detroit - that it was AT&T's problem. AT&T, naturally, claims that the problem doesn't appear on any other device, so it must be the device.
Can't wait for Windows 8 phones. I'm getting one.. ANY one.. the first day they go on sale.
Well I just got off of the phone with a level 2 rep from HTC, who seemed pretty confident that the problem is the rear cover. He is sending one out, and says if that doesn't fix it then it will be a phone replacement.

I'm more skeptical than you, trust me, but it would explain how so many people get the same problem with replacement handsets, as that piece is often not replaced
So, I'm in Florida for the week and noticed something.
In Detroit, the status bar says "4G"
In Tampa, the status bar says "LTE"
As before, I have not lost cellular data connection since I landed in FL. Kind of rules out the battery cover as the issue is gone, here. It appears the issue goes away in LTE areas while it's present in areas yet to get LTE. Detroit's LTE rollout hasn't happened, yet. So, it appears I've got another month of suffering before the problem is rectified.
One other note. With Internet Sharing set to ON...
In Detroit, my wife's laptop connects to the phone and can get internet.
In Tampa, my wife's laptop connects to the phone, but cannot get internet. It gets the error msg: "your computer is trying to use a dns server that is incorrect or doesn't exist"
My laptop works flawlessly connecting to the phone's Internet Sharing both in Detroit and Tampa. For the life of me, I can't find anything different in her settings over mine. Both are Win7. Hers upgraded from Vista, mine x64 and new this fall. Also, two internet-capable televisions connect to the phone and get to the internet flawlessly. But something with LTE doesn't like my wife's computer. Odd.
Honestly, I adore everything about this phone except for the data connection issue in Detroit (and a few other areas, it seems).
There HAS to be a setting or SOMEthing I can tweak to get this thing to work in Detroit.
Check battery cover, radio negotiation, firmware of radio

Hum.. that's curious. I had the original titan with similar issues.
I disabled wifi when not connected. I replaced battery cover also. The titan2 supposedly fixed that issue with the battery cover because it was a design flaw.
The radio supports 2G, 3G/4G/H and LTE. You may want to check it. You can set the radio it uses and not let the firmware decide which radio to use. You can check the service menu, I forgot the code. Just search for it.
If you use 2G, data and voice are not supported simultaneously. Check and make sure the contacts on the battery cover and on the phone are clear of debris. Use a solution to clean the contacts on the phone.
In the past I manually set the radio to 3G (HSPA and HSPA+) [HTC Pure, HTC HD2 on at&t]. The 3G radio is mature and should have less issues with the radio negotiation.
BTW, there is a keep alive wifi app also.
Thanks. I'll have to look for the codes. It's pretty obvious after going back and forth so much that the Titan II has a flaw with the way it handles AT&T's 4G. Scanning the maps from others who have had problems all show that they're in areas with 4G but without LTE.
Yeah, if I could force this thing to do LTE or 3G I think we'd be fine. It's the Best Phone Ever so long as it gets LTE, 3G or Edge. Anything else and it's crap.
Yes, back connector is okay and I've done this every way one can think of and kept notes. WiFi doesn't matter. On or off, the T2 will lose cellular data connection randomly in 4G areas. NOT in LTE areas. I'm only unable to test it on other carriers.
Similar problem with data
So I have had a similar problem -
I had a Samsung Focus, great phone, but I wore out the USB port - wouldn't charge consistently or sync. I figured I might as well use the insurance I had been paying. They sent me a Titan I - it had the bad microphone issue. So after some messing around they sent me a Titan II.
It has never had consistent data connection. I am in an area where I get the 4G icon (not LTE).
My experience tells me that if I move around and change cell, or lose signal in the cell I am in for any reason, then the phone will NOT connect back to data. It can (almost always) still get phone calls and send/receive texts and so on, but no data. Toggle airplane mode always fixes the problem, until the next time.
Originally HTC wanted to send me a new back cover - AT&T have been completely useless, they have no idea. Eventually after messing around with factory resets, powering on and off continuously, another new SIM card, HTC decided they want the phone repaired or replaced (level 2).
It is still inside the 30 day limit for exchanges from Assurion (AT&Ts insurance carrier) so it's getting replaced. I'll let you know if it fixes the issue, but I haven't been in an LTE area so I can't check that.
Personally I think it is a problem with handing off/reconnecting to 4G tower service - we'll see......
Anyone have the radio codes?
I've had the same problem since I got the device as well; but have noticed that it doesn't happen in all areas around me. My house is one of those areas though that I always lose connections. I've tried every APN / idea I've found on the internet with no luck. It's clearly something to do with AT&T towers. The only think I've not been able to try is a different SIM card in the same phone since it requires a '4G' sim card to even work at all. However the same SIM does work fine in '3G' only phones.
Going with the radio idea, does anyone have the codes to turn off the LTE radio? I just saw the list saying this phone will be long gone before AT&T ever gets LTE in Colorado so maybe just turning it off would help. Every code i found was for the T1 though and it didn't work on my phone.

I'm more skeptical than you, trust me, but it would explain how so many people get the same problem with replacement handsets, as that piece is often not replaced

UPDATE: HTC insisted on sending me a new SIM card cover (since it contains the radio's antenna). Despite my argument that the fact it works in Florida negates antenna as a suspect, they sent it along, anyhow. Naturally, there is no change. It still randomly drops cellular data. And now, I've picked up another spot on the freeway where my calls get dropped. Granted, it happened ONCE, so that could be any number of things. Long story short, it's not the antenna.
Next idea?
Well, I'm in Florida and found a spot where the phone fell back to 4G from LTE. Data issue returned. So, that takes geography out of the equation. The phone can't hold a data connection when using 4G. So, should I go for a fourth unit?
My addition:
AT&T recently rolled out LTE to my area in CT. I never had the problem before on straight 4G. Now, when I go from LTE to 4G (my drive every morning) data just stops working. I push it in to airplane mode and back out again and it works.
BTW - I am running Tango, so that is not likely to be a fix unless a radio update is released with it.

AT&T just switched on LTE metro-wide, last night. Now, the Titan 2 performs just as it does when I'm in Florida. It's nice having a data connection that'll stay good all over town, again.
I have spent some time discussing this with HTC and AT&T. Actually just got off the phone with HTC level 2.
I too have gone through all the options - new phone, new cover, new SIM card (you can just go into AT&T and ask for one, no charge), hard reset, everything.
From the information in this thread, and elsewhere I can say that the phone drops data on one of two things happening:-
- connection to tower is interrupted in current cell, but is re-acquired
- connection is handed off to adjacent tower as you travel to a new cell
Both these things will drop data IN 4G AREAS ONLY. If you are lucky enough to have consistent LTE in your area, you shouldn't have any problems.
Right now I'm working on getting the service menu codes so we can play with the radio settings. It sounds like HTC support reps have been forbidden to give these to end users on windows phone devices (I wonder why??!!).
If I get this information and it provides a fix for this issue, I will (obviously) post it, and I imagine HTC will as well. Here's hoping.....

I love my phone and have no plans to upgrade it. I haven't ever tried to root and don't plan to. It is totally stock. At the moment it is freshly reset using the recovery mode and not the reset option from with the settings menu.
For many months I have been having wifi issues. Now, it won't work at all. I've seen various suggestions online to try and nothing helps. At the moment my cell phone service with Verizon is suspsended cause we are broke and couldn't pay. It will wait until the first of the month. My Verizon Note Pro tablet is also on our plan and therefore without Verizon connectivity and it connects to the wifi just fine. My phone should be able to also. My husbands cell phone connects and stays connected like a champ. Also, the wifi is out of our control. We live full time in our rv and the rv park provides the wifi. I mention problems to them and they automatically say its not their hardware/software, it's ours. Or they say to call the ISP.
I am including a screen shot from the phone to show what my versions of things are. Anyone know how to fix this? I'm even willing to go so far as to take it apart. I'm not a newbie handling the hardware, I've done laptop repairs and have the tools. I don't especially want to take it apart because that does up the risk factor of totally breaking it once and for all but, I do have another phone to fall back on if my note 2 totally tanks it. Thus far my only problem is this stupid wifi connectivity issue.
Any help would be greatly appreciated.
