So I just picked up a Thunderbolt from a local Verizon corporate store. The sales rep told me NOT to use WiFi on my phone because of an issue all Thunderbolts are having. She said once connected to WiFi, it won't be able to switch back to 3G unless you perform a factory reset. It sounds like a load of crappy to me, but I'd rather play it safe. Can anyone confirm or deny this out there? Thanks in advance!

I think I've read about a few people having that issue, but simply switching airplane mode on and off fixes it, I believe.
Pretty sure that rep didn't know what the hell she was talking about. I think it's a safe bet these and other boards would be blowing up if there was a problem as massive as that affecting ALL Thunderbolts.
And my wifi is fine!
yea mine doesnt want to switch back to 3g but a simple restart does the trick, and some vzw reps are idiots deff no factory reset
I use wifi all the time, no problems here.
I use WiFi at home and 3G when i'm at work, i have no problem switching between the two, the sales rep that you were talking to doesn't know what he was talking about

Same here no problems switching from wifi to 3G or to 4G
I've heard people complain about this, but the solution for now seems to be turning airplane mode on and back off. From what I've seen it's not a super common problem, I've never had an issue.
Yup, no problems here.

Sometimes my wifi stops working even when its been on all day. It shows its connected and I have a strong signal, but when I try to use an app that needs a connection the app wont connect. The only thing that fixes it is turning wifi off and back on again. On top of that I noticed huge drains on my battery when this happens.

same thing happens to me. then if I turn off my Wi-Fi sometimes to try and get a 3g connection it takes like 10-15 tries to get a data connection. And even sometimes when that happens I'll turn my Wi-Fi back on and my Wi-Fi acts buggy, doesn't connect... I'll have to try the airplane mode trick
I have the same problem. Changing the EPST setting as found from an Engadget Post:

Sort of fixed the problem. However, I rooted to Tesla Coil and now cannot use the "##778#" easter egg dialer anymore.
Just tried the Airplane mode and phone rebooted, doh. Again, after starting up WiFi, no 3G coverage.

No problems here. I use wifi 90% of the day. Although, strangly my router now shuts off its wifi signal ever since I bought this phone. I have to go into my router and setup the network again.

I've had two Galaxy S II phones now, and I've had the same problem with both devices. The phone's wifi is great -- when it works. Although I noticed that the death grip lowers the wifi signal bar, I can still browse the internet and download apps just fine.
The problem is that, at times, the phone will show wifi connectivity and yet, I can't browse the internet or access the App Store. I'll have to shut off the wifi multiple times and even this doesn't work 100% of the time. Shutting off the phone and turning it back on works 100% of the time.
Since this has happened to two phones, I'm beginning to question whether I have an issue with the wireless router because I have not come across this as a prevalent issue. At the same time, my laptop and a family member's iphone doesn't have the same issue.
Anyone else having this problem? Or have suggestion for fixing the problem?
Thanks
Here is me showing the problem on video:
My roommate and I both have the Galaxy SII and he constantly has problems connecting to our wifi. The only difference in our phones is his is rooted and mine is not. I plan on rooting my one of these days but would like to fix the other issues I am having first.
Mine isn't rooted, but it still has the connectivity problem.
EDIT:
I may have found the the solution. Probably unique to my situation, but what I did was disable WPS on my router. It's a medialink router and I thought I had disabled it (per instruction) but it was on. Perhaps that was the issue. So far, no problem.
EDIT:
Nope, the wifi has dropped again. By dropped, I don't mean it drops in the middle of browsing. It seems to drop after I've stopped using the phone for a while. I've already checked to see that the phone is to never turn off the wifi when the display is off/sleep.
Arghhh
same exact problem.

Don't have any issue with wi-fi , mine is rooted on stock rom
i have no issues with wifi on my sgs2, i have wifi on 24/7, and on wifi proabably 50% of the time. it connects and disconnects when supposed to, picks up on cell data and drops when its supposed to..
fwiw, my GF has an iphone 4, she had problems connecting to the HOME wifi, but no where else, i updated the firmware on the router, same problem, i swapped out the router for a spare a friend had, and setup a second access point on the same network, just called it the same SSID but put a "2" after it.
her connectivity problems went away, immediatly she noticed a difference and has never complained of a drop since...
try different encryption methods, if you're using wep, try wpa, try a few different things.
also try a firmware update, you might lose your settings during a firmware update, but there is usually a backup/restore option you can use. backup your settings before flash, then restore after. if you have access, for at least testing purposes, hook up another router and use it to connect to and see if the same problems persist.
No problems at all connecting to a WHR-G54S running Tomato.
The Moto Surfboards are known to be flaky.
I had the same problem. after getting another one I found out that if I didn't download so many apps at one time the problem mostly stopped and after running a couple weeks, I haven't had the problem with connection since. I'm not sure it will help, but I did a factory data reset and reinstalled the apps one our two at a time (it's frustrating, I know).

I'm using an Atrix 4G on 2.3.4. The wifi turns on, but won't get past scanning. It won't connect or find any network, even if I've added it, and even if I'm right next to the router. Is this a software problem? or hardware? I've seen posts about wifi problems, but none like this. Do you think flashing the sbf or a custom ROM would fix it? I've tried countless factory resets, but to no avail. I'm rooted, but don't have an unlocked recovery.
A few weeks ago, I had a wifi problem that was obviously hardware, (wifi wouldn't turn on without rebooting, bluetooth wouldn't turn on at all) and Motorola requested I send it in. They replaced it with a new unit, I literally got it back this week, and the wifi is crapping out again. SO FREAKING FRUSTRATING. Especially now that AT&T is throttling unlimited data users.
Seriously, any feedback at this point will be greatly appreciated. Thanks in advance!
I had a similar issue. What I did to fix it was I set my router to use at max "G" protocol.

Thanks for the response! I'll figure that out now. But what do you do when you're not near a router you can control?
Have you had an opportunity to use it on another wifi network? My problem was just with my specific router so you might not have that issue depending on what router it's trying to connect to. It's possible this might not be the issue at all, just a suggestion.

Yeah it wouldn't find my girlfriend's either, but we have the same router. Im thinkin its in the phone though..
I use 2 routers at home, one wireless G and the other is set to wireless N only (I set this to N only and only use wireless N devices on it so as to maintain maximum bandwidth). I have no problems connecting to either on multiple SSID's. Wireless G is a Netgear WGR614v9 on stock firmware. Wireless N is a Netgear WNR3500L running WRT firmware.
I'm dumb. Haha but how exactly do you set your router to G only? And ..what exactly does that mean...?
And I guess the real question is, since I've factory reset it several times and the problem still isn't fixed, does that mean it's a hardware problem? Or are there areas that a factory reset wouldn't reach, but that a flash would?
My wifi connection is dropping within seconds of connection. The phone switches to 3g, wifi turns back on and connects again for a few seconds, drops then kicks back onto 3g.
Ive had this issue on multiple roms, so I am relating it to something similar to RezRom and CleanRom or to the leak itself.
Anybody have ANY ideas?
Update: seems that after the firmware update, my router and phone did not like each other. I was able to tweak my router quite a bit and it appears that the dropping connection issue is resolved.

It is a wireless N router? I do believe I read that our phones are having issues when on the 5Ghz band.

The phone does not have 5GHz abilities, but regular 2.4Ghz N is supported.

EDIT: Take that back, however it doesn't see any of my 5Ghz access points here at all.
I have a wireless N router at home with no problems. It is on the 2.4ghz band though. I think.

I'm having the same problem. However, mine doesn't drop out within seconds, it'll probably be good for a couple hours then I'll notice it's trying to sync with my Exchange server for a while, and will eventually time out and then I lose all internet connectivity until I turn wifi off and back on again. This happens on multiple wifi networks, including wireless-N and non wireless-N.
I do also see that the 3g icon will come and go every few seconds when connected to wifi. Anyone know if this is just a bug with the new ICS leak or is there some kind of fix floating around?

I am unlocked and rooted but I am running the stock ROM and mine does exactly what yours is doing. I don't actually know if this happens outside of my house since I'm generally using 3/4G then.
I have a thread on this in the question section but no answers yet.

This is true. The rezound does seem to have 5ghz capability. However my POS netgear doesnt get the same distance on 5ghz as 2.4ghz.
As far as what I did was actually reset my router and update firmware. This seems to have fixed the issue for now. I only started having this issue with the updated leak and it was happening on all roms and even stock. Reinstalling a ROM would fix it for about 2 to 3 minutes then it was back to switching between both data and wifi.
My phone burned up the battery in a matter of an hour and half as it was constantly going from wifi to 3g.
My phone does the same thing!! I think it happpened when I flashed the new leak zip without re locking vootkoader. In hoping that official ics will fix it

Just curious if anyone found a solid solution to the Wifi problem that we seem to be experiencing with the new leak? I tried the suggestion of disabling auto wifi in the dock mode but that didn't seem to fix it for me. I guess I'm just trying to see if this is widespread, or if it's only affecting certain people in different scenarios. It doesn't seem to be getting as much attention as the overheating/battery life issues that others are reporting.
So far I've tried connecting to multiple networks with different security types (open, wpa, wpa2, wep) all seem to the have the same result of showing that wifi is connected, works for a couple of hours, then will lose wifi connectivity, even though the wifi indicator is showing that it's connected. I've done everything i can think of other than re-flashing the ICS leak. I've also never unlocked my phone, just installed the update per the original instructions on Android Police.
I have searched all over and I don't find an answer, if I'm missing a thread please just point me in the right direction.
My home wifi has been working with my Note just fine since I got the phone (cue ominous music) up until yesterday. Last night, it started asking me for a password (which was weird, because it hadn't since I first got the phone and set the connection up), and I put the password in, but it kept saying "authorization error." I am really frustrated, I rebooted the phone, the router, removed the home wifi connection (the "forget" button) and reinput it -- I even booted into "safe" mode to make sure it wasn't some app -- no joy. It's a very simple linksys router, WPA/WPA2 security, all the other tablets/computers/phones in the house work just fine (tablets/other phone Android, laptops Windows.) And my Note was working just fine until last night -- no recent software install or update, it was seemingly just random. It's a stock Verizon Note, I haven't even bothered to root since it does everything I want.
Here's the kicker: I connect to OTHER public networks just fine. I connected to my work and McDonald's wifi this morning, no problems.
What could be wrong? I really need to be able to use my wifi at home, I don't see anything in Google or on the boards about this. I am hoping my search-fu is weak and someone knows what is up with this.
restore defaults on your router, then setup a new password.
Hope this Helps....

I have been experiencing this problem for the past 4 days. I have owned my Note II since December 25, 2012 and it has been working on any WIFI AP ive tried. 4 days ago in the middle of the day, my phone started giving out "authorization error" and would not let me log in to my home WIFI. I have 4 computers, 3 smartphones and other devices all working perfectly in my home WIFI. My problem even occurred when connecting to open, unsecured WIFI AP also. Nothing seemed to work. I called Verizon and did all the steps leading up to factory reset. With no luck on any tricks or tips from them I called Samsung. They walked me through the same processes and everything, so I decided to do a factory reset. This did not fix anything. I still get "authorization error" and "wrong password" on any WIFI i try to connect to.
I found out yesterday if I stand within 5 feet of my WIFI router I can connect and browse the internet for a few minutes until it kicks me off and does the same old "authorization error". If I sign in to my WIFI within the 5 feet and walk away, it disconnects and again, gives me the error messages.
I called Verizon back and they are sending me a replacement phone.
TL;DR:
Try accessing your WIFI when you are right next to it.
If problems still persist, call your carrier.
I hope your phone isnt as busted as mine.
Argh, that's bad. At least my phone connected to open networks so I knew the hardware was ok -- I wiped the router and set it up again (per the suggestion in this thread) and I'm good for now. (Embarrassed I didn't think of that myself) Hope you have better luck with your replacement phone!

Ok............ wow you have me 100% nervous now. I've been experiencing this issue ever since I unlocked, rooted and ROM'd my Note 2 back in the middle of December, and I experience the problem with only my Wireless-N SSID on my router. I can connect to the Wireless-G band just fine but the N one gives me this error no matter whether it's open or not. I seriously hope this isn't an issue of broken hardware..............
I figured this was worth mentioning. I have 3 Note 2's in my household, 2 of them are running Beans Build 5 and Perseus kernel overclocked and the other phone is totally stock.
All 3 phones have the exact same issue of connecting to the 802.11 N band on my router. They connect to the G band just fine. I think this rules out any worries about it being a lemon issue. Most definitely is a Samsung software issue that's been happening to multiple models going back a few years. Here's a google search of this issue using non-phone specific parameters. Notice how ALL phone specific forums point to a Samsung device.
I have a bad feeling that this is not something that will be getting resolved any time soon.
Edit:
The plot thickens. I have performed some tests on my router to see if I could get my phone to connect. Well here's my results:
5Ghz band = Wireless-N Only = Authentication error occurred
5Ghz band = Wireless-A/N Mixed = Connects instantly
2.4Ghz band = Wireless-N Only = Authentication error occurred
2.4Ghz band = Wireless-G Only = Connects instantly
The problem is clear. It's Wireless-N. I can connect just fine at Wireless-A speeds (54mbps max signal) and everything up to Wireless-G, independent of frequency, but as soon as I try to force Wireless-N onto my phone, it craps out and fails to authenticate. This happens regardless of whether I have the network encrypted or not.
And based upon my google search I have linked to in this post, I doubt this is something we can expect to be fixed anytime soon. Oh yeah and for the record, when I have my router set to Wireless-N only mode, I was able to connect instantly without error on my crappy old HTC Thunderbolt running a hacked together AOSP 4.0.3 ROM.
Yep............... GG Samsung
wireless n has been a unreliable joke since it was released...my favorite routers are the linksys wrt-54gl running linux dd-wrt firmware. one of the most affordable rock solid routers built. its only g band but most people do not need anything faster for home use. heck most of us cant afford the t1 type connection speed to utilize n band anyway.
Exact same problem as well...I'll have to try the Wireless N-only vs. Auto to see if that fixes it...
EDIT: Both wireless mode settings of 'N-only' and 'Auto' caused the problem. I had to set it to 'Legacy' in order to get the connection to stick without authentification errors. Have an ASUS RT-N66U router...
EDIT 2: Did the same thing on my Cisco E3000 and it worked as well.

It's not Samsung. There have been issues with myriad devices and wireless N pretty much the whole time it's been around. Android OS or the the N standard-- I personally know people with other manufacturers hardware and the exact same issues. If it's an OS problem, you would think it would be fixed by now, but who knows, like was mentioned above, very few people need the bandwidth that wireless n can theoreticly provide.
Good Luck,

It's definitely something specific with Samsung and the N2 since my cousin's G3 connects to the same router on 5GHz WirelessN/Auto with no issues at all. I think they have a bug to fix...
Can someone else perform a check with their Note 2 on a Wireless N only setting? It seems this is a bug that really need to be fixed.
