Over the past week or so my phone has decided just to cut off while in my pocket, it turns back on right away. I can't seem to pinpoint any particular time that it turns off because I don't know it's off until I look at, although oddly it seems to happen only when I am at home. It is rooted and running BAMF with new radio and the default BAMF kernal. Also there was a full cell phone coverage outage in my area recently if it has anything to do with the new radio.
Possibly overclocked your kernel too much? Or maybe with the new BAMF feature of waking your phone on the volume keys you are waking and rebooting your phone without realizing it?
Thanks for the reply, I will try changing kernal settings and see if I notice any change.

There's your problem, I'll bet.
I was fine with the "old" (original) radio revision, but I upgraded to the rooted, but otherwise stock "leaked" version, which included the new radio stuff. It seemed to be fine at home, but I was travelling out of town today, and it rebooted at least 5 times this morning. 3 of those times, without having really done anything with the phone. After a reboot, I'd connect to the WiFi at that site, then just let the phone sit on the table - it would reboot again within an hour. I did try with cell set to both LTE+CDMA and CDMA (auto), didn't seem to make a difference. Maybe it depends on what brand of local BSS/BTS (Nortel, Lucent, Motorola).
So, I flashed the old radio back on (didn't change anything else). It went the rest of the day without rebooting.
I realize this is just one anecdotal bit of data, but it sure points to the new radio, in my case. If you look around, others have blamed reboots on the new radio release, too.
Hi,
Sometime today I lost my phone signal on my SG2. I'm not sure exactly at what moment as I first noticed that I had a couple of bars but no 3G when I tried to browse the web. So I restarted the phone but to no avail. Since then I've lost all bars and can't make any calls either.
The only thing I have done today "out of the ordinary" was to connect to the phone using Wifi File Explorer to transfer a file, which I tried to connect to without being on a wifi network by first trying the "Wifi Direct settings" in Settings, which didn't work, and then by tethering by Wifi which worked. Maybe some setting got stuck in the process, but I'm not sure since never checked if it worked right before and after.
If anyone has any idea what could be wrong please let me know, as I am literally without a phone!
I recommend downloading http://www.androidzoom.com/android_applications/communication/no-signal-alert-pro_fyyo.html this will definitely be of benefit to you if your suffering from signal problems, it has been of good use to me.
Check your IMEI is the correct one for your phone .If not restore your backed up EFS folder .
Or try backup data and factory reset as a first step.

Thanks for the quick replies!
The IMEI does not correspond to the one I have written down, though I'm not 100% I what have on my note is the latest IMEI; but how could that change though by itself, if my note is correct??
Also, I just saw something very strange: I turned on my phone and had full bars (no 3G though), and right in front of my eyes all bars dropped, one by one, during the course of 5-6 seconds. Something is VERY off...
Regarding factory reset: my phone is rooted (thanks to XDA!) and I have Tit.backup: can I will my phone still be rooted if I do a factory reset?
Something went probably wrong when rooting it (not neccesarily any errors) and effed up tge EFS folder.
Try to flash back to stock ROM, it might work to restore your.folder.

I should have been more clear on that, but I rooted the phone about a month ago and it has worked flawlessly since then, so it couldn't be that.
Anyway, I looked around a little and found this post:
http://androidforums.com/samsung-ga...connectivity-but-no-idea-why.html#post2722784
He seemed to have had the exact same problem that happened to me, so I decided to wait, and sure enough the connection reestablished itself about an hour ago and while I was watching for it, with the signal slowly creeping back up during a couple of minutes, and several hours after I lost it. Very odd.
This surely has to be an Android bug but that only shows up under certain and rare conditions.
To be sure I made a speed test and got 4.84 Mbps/up, 1.19 down, which I guess is fine; I never did one prior to this so I have nothing to compare to.
Again, appreciate the advice!
EDIT: For posterity, I should add that during these hours, even when I briefly apparently had a (non-3G) signal, I had a notification during all this time saying that I could only make emergency call.
I'm having the same issue. No Bars at all most of the time and when I have some, it never connects to 3G, G at most, and can't load any thing at all.
Very frustrating. I have been using Lite'ning rom 6.1 for a few months and had no problems at all until about a week ago.
I flashed back to a stock rom and still having the same issue.
I've also seen the bars drop down one by one in a 5 second window, bizarre!
Anyone find a fix for this? Or could the phone be faulty?

I was on Lite'ning about 3 weeks ago and actually completely lost signal several times. Reboots and hard resets solved the problem temporarily. I then flashed Batista FH 2.4 with ICS and things were great. I'm now on GingerMod. No issues.
I don't know how it could be kernel related though, especially if you are 100% stock again.
Ive searched the forums, googled, factory reset, messed about with *#0011# power save, rebooted/forgot router and I'm STILL having issues with the wifi dropping and reconnecting periodically (maybe once every 10/20 mins?) . Im on BLG8 which is as far as i can tell the latest firmware (im not rooted) for the UK.
Has anyone got a solution to this? The main reason is I use Skype a lot and the call will just drop (obviously) with the wifi drop outs.
No other device has issues with my wifi router.
Any help would be much appreciated
Cheers
Does it make any difference how far you are from the router? Does it always connect fine initially?
I'm having the same issue and i've tried every fix that has been suggested. I dont understand after spending the amount of money i did on this phone that i have to run through the dialer to get it to work properly sometimes. Then other times it still drops out and wont come back on for 5 to 10 minutes. I've changed roms, kernels, and wiped completely i dont know how many times and went back to stock. Still works sometimes and hangs up others. There doesn't seem to be a permanent fix for people lucky enough to have this issue still. My 30 day return is way up and gone so i cant send it back. Samsung cant seem to give me an answer. I'm at a loss for words.

My 30 days was up, it's still been replaced under warranty. I took it to CPW who sent it away, it came back 'fixed' so I asked them to log into their WiFi... of course, they couldn't and the guy said he would order me a new phone but it would need to come from Samsung. My new one has blazing fast WiFi!
i have the same problem. i was hoping a new rom would fix it, but FWIR its busted. i get 2 bars MAX no matter how far i am from teh router. its fast enough, but it drops out constantly.
also my screen is sometimes slow to turn on from sleep.
im on vodaphone if that makes any difference.
Guys... I had a very similar problem with my phone.
First of all WiFi became very unreliable.. like yours. I changed ROM and it still persisted. I even went completely back to stock.. and it still persisted. Dropping out.. no reliable connection etc etc.
Then it started being really weird.. the touchscreen started responding intermittently. Sometimes I couldn't get it to unlock. And this was all on stock.. no root etc.
I was ready to send it back to be repaired.. and I came to the conclusion that there must be something staying the same.. even after a wipe / reflash. Maybe one of the other partitions was corrupt???
Now I'm not clever enough to investigate.. but I did come to the conclusion that a repartition may wipe everything and make it a real fresh install next time.
So I found an appropriate .pit file and stock ROM and used Odin to flash the ROM and partition the phone.
And it is now all fully functioning again.. no WiFi issues at all.

It seems to have improved with the latest JB leak, still every now and then but certainly better - i did a full factory reset + cache wipe in stock recovery (im unrooted etc). Still, would a modified kernel/modem fix this very common issue?
This problem is everywhere it seems.
OK so really weird update: my screen unlock is still a bit slow, but my wifi hasnt dropped for a few hours. i went through all the vodafone crap and updated/ran/configured it all, and now it seems fine. seemed vodafone wanted to verify my phone+sim details but couldnt over the wifi so kept trying to do it over the 3g, but couldnt do it quickly enough so the wifi cut it back out again. I have a headphone amplifier that is very sensitive to mobile phone signals. it beeps 4 seconds before i get a message or phonecall, and "ticked" at me whenever my wifi dropped out. its not ticked in hours.
TL;DR anyone on vodafone, run your "my vodafone" application and configure it all. might fix it.
Mine drops wireless a lot when connected to wireless A networks. It seems stable on wireless N networks. Anyone else notice A networks to be worse?

So, I've only had my LGOG for a day and a half and I am having issues connecting with WiFi. At first it worked fine but when I left the coverage area and return a few hours later it would not connect. Tried turning off the WiFi but it kept turning itself back on. I reboot the phone and it works fine as soon as it boots up it connects the WiFi no problem. It is my work WiFi and I had no issues connecting to it from either my iPad nor my HTC One X that will soon find it's way to eBay thanks to this beautiful LGOG. If no one else is having issues, I will call AT&T and have them switch it out. I just wish there was an easy way to back up everything, I mean my home screens and app locations exc. It takes so long to set everything back up the way I find most useful.
WiFi on my device has been excellent.

The Wifi performance of this device is unbelievable. I get the best speeds I have ever seen with any device including PCs. It's either a faulty device or maybe your work has strange security settings?
I had this same problem with my LGOG and my home wireless network. It just would sit and try to connect until I rebooted the phone.
That was on stock though. I have not had any more problems with it after flashing the base rom.
My work has standard WPA settings and it was connected fine yesterday. I left again during lunch and when I came back, same problem and had to reboot the phone. AT&T is sending me another one already and a free case. Can't be too mad about it I guess and at least the phone reboots fast.
Have you tried using the ATT smart wifi app? Fixed the exact same issue for me.

Twice My O.G. wouldn't connect to wifi networks even though it had connected to them in the past. I tried to turn it off and on and scan for the network that I am in range of and it wont show any networks it just says "not in range" when I am in range. So to remedy the situation I turned the phone off and then on. It has only done this to me twice but it's a real nuisance because both times I needed wifi. My phone is stock.
You're in a minority. This thing's wifi blows most other wifi implementations out of the water.

I wish my wifi would stop re-enabling itself. It's chewing up my home bandwidth.
I have been having this issue as of late. It seems to have developed this habit in the last week or so. At first I thought it was Time Warner trolling me but it started happening at work. Something tells me it has something to do with the stock At&T Rom putting the wi-fi radio to sleep and not being able to bring it back online. Reboot fixes it most of the time but sometimes it takes a couple attempts. I have been hesitant to mod this phone still because I would really like to see CM working well before I flash. Also my instinct tells me another possible culprit could be IPv6 on certain routers. That, however, is far less likely unless someone with a decrapified Rom has experienced this issue as it would be a cross platform issue in this case. Anyone else have any insight? Otherwise it's time to get rid of the Att rom.

Same issue here. This is my second LGOG and have been happy with both except for some minor glitches on both with the keyboard freezing up as well as with the WiFi not re-connecting after leaving the area. A restart normally fixed both problems. My first one bricked after rooting and removing all of the bloatware (the phone checks for certain apps upon booting to keep you from removing stock apps). Tried a fix but I couldn't get a Rom at that point as the phone had been out on the market for under a week. I haven't messed with it since but I may try a new Rom and be able to fix the WiFi and get rid of all the bloatware that way.
Just got this ROM running today. No more WiFi issues at all. Some minor ui bugs I am OK with.

Seems like, as usual, At&T bloat ware is the culprit. I experienced the same on my Aria and Inspire. Hope this helps and good luck.
Also I had the keyboard problem but that went away when I switched to the Android default keyboard. One of the other reasons I decided to root was because rather than freezing, the Android default keyboard started typing then the auto correct broke and stopped displaying the words unless you touched the area you were typing in. It really bugged me when it started doing it right after I factory reset. Weird huh?

LG Optimus G Wi-Fi Receiver Disconnect Issue
Funny...I've had some weird home wi-fi issues on two of these.
To explain, I bought mine in December, stock OS of course, and immediately noticed it turning off my wi-fi every time I tried switching between the two home wi-fi SSIDs I created when I upgraded to DD-WRT. This also occurred outside my house, but stopped shortly after the nearly-immediate Android OS upgrade came over (and forced me to install it, I might also note; I'd read the thing was just more AT&T bloatware, but two or three boots later, apparently I got no choice, and it auto-installed).
The good news was, somehow, this 'update' somehow stopped the thing from turning the wi-fi off when I switched between IDs (my base router has a 5G 2nd network which I wanna use when I'm around it, but DD-WRT won't support, as far as expanding it--thusly, I have another 2.4GHz signal I use and relay out around my yard).
That bad news is, though, that I screwed up the phone with the Root Toolbox (Lite) by merely fiddling with their bootanim settings on that original phone. And I mean bricked it, solid.
I'd never bricked any phone, so this ticked me off. Luckily, I was still within 2 days of my 30-Day Best Buy in-store replacement warranty, so I took it back, they fiddled too, and gave up on it.
Hence, my 2nd phone...which now, even after the system update direct from AT&T, still turns off my wi-fi every time I try switching to that 2nd SSID, so I'm left wondering if it was even the same update; I don't think I did anything else, and can't see it as a settings issue, because it did it right out of the box, and the first one stopped after the only system update before I got a chance to even figure ANY user settings out, much less any network ones.
So, now I'm 'going shopping' for 'some PlayStore app' that will skip this B.S. and automatically connect to the strongest home wi-fi signal (within reason--sometimes they're equally strong), without obnoxiously turning off my wi-fi receiver as I look at it.
This kind of malarky could spoil some phones for some people, but I'll struggle along due to the speedy quad-core in it [sigh...wah!].
I guess I'm a big baby, seeing as how I don't write one iota of code, but my personal haughty view is that any dedicated wi-fi devices should have better wi-fi connection than any Windows OS made...and, so far, this'n doesN'T!
What a dumb thing to let happen in such a potentially awesome phone...[AT&T!!!]
This might work or not but can't hurt to try. Apparently some people in the new snowleopard JB thread was having similar issues and for a few, changing the security from WPA2 to WEP worked. Although mines been good and fine on WPA2 but worth a try.
Using wep in 2013 is beyond retarded.

DUDE! Senior Members here can be a little uppity and rude...even if they're completely correct.
Glad you called out the 'behavior', and not the 'member', though...
but enough of the technicalities...I'm still looking for solutions...beyond blaming AT&T (too easy), or even the strangeness of getting into blaming some weird kind of manufacturing errors (QC at best), I'm left waiting for a substantial OS update (like, oh a better place of decimal, perhaps?), or worse, an app...anyone look at the state (and sheer number) of 'wi-fi' apps? Anybody here can guess, they number in the thousands, and a Play search for 'wi-fi' gets you astronomically different results from 'wifi', even, so I'm not sure I need to be looking at that.
Maybe it's even somehow that, with the first phone, I noticed this, and somehow added my own home network to the AT&T Smart Wi-Fi 'bloatware' that came with the phone (not the worst evil they've ever done, so far, BTW--it does exactly what I imagined should be going on in the background while you're driving around, indexing locales with free Wi-Fi for you to choose to save later...an idea I would call 'Tarzaning', if you get my drift).
I'm gonna try changing two settings in the AT&T 'Smart Wi-Fi' bloatware to 'My Spots' temporarily, at least, to see if it'll latch onto my home stuff more aggressively. I just can't wait to report back my fantastically successful findings here (right after I buy the domain name 'snarkasm.net').
Oh crap...it's already taken.
Is the AT&T smart wifi thing enabled by default? I can't remember. I thought it sounded useful so I played with it a bit but ultimately I didn't like the way it worked so I disabled it.
Still wanted some way to auto-enable/disable wifi. I didn't have anything to go on, but I picked up "Smart WiFi Toggler" which seems to work well. It uses location-based rules (based on cell signals) by default. I also use AutomateIt to turn off mobile data once wifi has been on for 1 minute, and turn on mobile data immediately when wifi disconnects. I have no idea if this saves me any battery life, but I do it anyway.
Hi all,
First, a bit of phone history. I rooted my phone before 4.4 and my sole purpose of rooting was to have the WIFI tether app working since I use my iPad at work and wanted to be able to connect to the internet there using my phone. I didn't care about custom ROMS, since I really don't have the customizing curiosity most of you have with totally overhauling my phone. (I'm getting old, I think, heh)
So it was working fine all summer and then about 2 months ago after I said to myself, "Hey, I wouldn't mind having fastboot turned on again", my phone got stuck in a horrid bootloop. It took about 5 hours of rebooting and swearing for it to finally give me any access to the bootloader.
When I was able to do anything to the phone, in a panic, I simply did a factory reset.
It actually went well. Though I had to do it twice for it to go smoothly. Now my phone runs much smoother. (Even though I don't do custom ROMS, I do install a ton of interface tweaks from the App Store. And yes, I pay for them) Also the battery lasts a LOT longer.
Now the bad news. My bootloaded shows I'm tampered and unlocked, but my superuser must be broken and nothing on the phone shows I'm rooted. Root required apps won't work and apps to check if I'm rooted say I'm not.
WIFI tether of course also doesn't work but that's not the problem I'm asking you all about.
The REAL problem is my 3G/4G radios seem to be broken. What I mean is if I set my phone to be LTE/CDMA the phone will switch back and forth every couple minutes between the two regardless of signal strength leaving the connection gone while it keeps switching back and forth. If I leave it on CDMA only, my connection is fine, except of course I'm on 3G which is slow. (duh) This problem occurs anywhere. The same at work or at home 20 miles away, which I assume uses a different tower.
Yesterday my boss at work got a new Galaxy 5 and asked my to help him set it up. We are both on Sprint and work in a factory which causes the 4G to be quite slow inside, but I promptly installed speedtest and ran it on both his phone and mine (I turned my 4G back on for the test) He scored a 22 Mbps while I scored a .5 Mbps.
Yikes! I guess my radio really is broken.
Can anyone help me to get this phone going in either direction? Either fully rooted with the radio and WIFI tether fixed or even backwards going unrooted stock with the radios fixed?
I'm heading out right now so can't reply right away, so forgive me if I can't answer any questions until later tonight.
Thanks in advance!
p.s. I'm fairly knowledgeable with computers and can follow most rooting guides without hand-holding, though I admit some of the Rooting process is beyond my grasp since I'm not really into the developing mindset.
Yikes, 24 views and no replies. I thought I might have been too long winded . ?
I should have just posted this; Help, I'm unlocked but my superuser isn't working
?
Hello, I am by all means no expert and i had seen this and figured one of those would come here and help you but it seems everyone may be busy for the holidays. Kidding aside, if it were mine and this happened what I would do is flash a custom recovery like TWRP and then it will tell you you are not rooted and then you can install supersu from there. There may be other ways or easier ways to accomplish what you need but this is the method that I personally would try. I know just enough to get myself in and out of basic situations but I do believe this will work for you. Maybe one of the more knowledgeable folks will chime in with some better advise. Good luck and let us know if you get it sorted.

Thanks Byron, I'll give it a try after work, don't want to screw up my phone right before I need it.
I still haven't tried it yet, I want to wait until I'm off for the holidays to blow up my phone
