Think the wifi might be flakey on mine.

Looks like my Galaxy Tab 10.1 is having some odd wifi issues.
It started when I tethered with my Galaxy S Vibrant phone. After about 15 minutes the phone would freeze up and I'd lose network connectivity on the tablet. The mobile AP app is unresponsive and I have to reboot the phone.
I've tether other tablets and never had this problem. I tried a few times and the GT 10.1 froze up the phone every time after about 15 minutes. But tried again with my iPad and Nook Color and it didn't have any problems.
Then I get home and use my 802.11n router. And I start running into intermitten network connectivity drops. Market and other apps will sometimes give a "no network connection" message and ask me to Retry, which usually then works.
I also see the wifi icon turn from blue to gray sometimes.
Tried my 802.11g router as well, some deal. So I think it's something quirky with the wifi on my tablet.
PS. One thing I just realized. This only happens with apps that are running in the background. If I'm watching YouTube or I'm downloading apps from the Market, I never ad it give me a network error in the middle of this activity. But if I switch a background app, then it'll tell me no network connection.
Maybe I should do a factory reset first.

that is very weird, I have had my galaxy tab since the 8th (went to the NYC launch) and I have been tethering it to my thunderbolt with no problem.

On mine, default wifi setting was to turn off when screen off. I changed it to never.

It may just be a bad unit, mines been solid

Factor reset didn't help. And wifi policy is set to disconnect never.

Same thing happens to me. This is my 2nd unit. First one was fine. just traded out for the grey, but they both have the same issue. No issues when I'm tethered though.

Wi-fi conections and my galaxy tab

Hi again, since my last problem, that my galaxy tab did not wanted to turn on, I got a refund and waited until the machine came to my country..... months later, I could buy it at walmart, and all went fine, I got a 16GB wi-fi/3G tablet and went to a friend's house to use it, wi-fi worked well, then I bought a router, and installed it in one of my houses, and all went fine, I could even use it 20m away, then I installed it in my actual house and first it came ok, I could connect it, and worked for several days, went away and used the 3G internet, and came back and used the wi-fi because it has better speed, and it started to don't work, so I reseted the router like 3 times, each time it didn't work, then I contacted a friend of mine that works installing routers for companies, and he configured mine so it had a better security and values he knows that would work better, and indeed the problem was solved... for a couple of days... now, it says connected and it does not charge the pages, or if I "forget" the network, and charge it again, internet works but it loads pages partially it does not load them completely. On my phone and laptop the internet always works, in the tablet that is the problem... so what could it be, or how could I fix it?
PD: this is really strange, because normally it happens either when I shut down the router (because it is right besides my bed and the computer (big desktop) makes noise) or when I leave the tablet in stanby for a day or so, I write this because now I just restarted the tab and internet worked as if anything had happened...

I was recently having problems with wifi also. Mine was connected to my network but I couldn't get on the internet. This happened after a few weeks of ownership with no issues. I found this article and it pertains to my issue, not sure if it will help you though. You do need a rooted device to be able to do this "fix". It worked for me though.

Ok thanks so to root it, is the method suggested in the article safe, or what could I loose with that procedure? meaning, do you know a trustfull procedure I could follow?

I had the same problem too recently...works well at my friend's place but not with my router...it seems that the tab works well with static ip and not with dynamic ip address with we people usually have...
Oh , just read that link...i was about to say the same...
There s another way...
Without root,
reset your router
go to your wifi settings
go to wifi channel
set the channel to 11 (6 or 4 works too)
these channels tend to workout the problem i heard...worth a try right...
You can try this before you root

WLAN-connection hanging every 30 mins

I got my 7.7 yesterday. All is working great, but about every 30 minuttes of use, the WLAN-connection hangs. The WLAN-icon stays lit, but the tab is not able to send/receive data. To get it to work again, I have to disable WLAN and then enable again. It then works for about 30 more minuttes.
I have not installed any task-killers or battery-enhancers etc..
The router is a D-Link DIR 555. I use several PCs and Phones on the same router without losing connections ever. Encryption-type is WPA2.
Any ideas?

Bro here is the same problem really confusing me evrytime the wlan disconnects.

Have you checked that your WLAN settings do not put the tablet wifi to sleep ?
Settings -> Wireless and Networks -> Wi-Fi settings -> Wi-Fi sleep policy

I'm having the same problem here, and my wifi policy is set to never, so when that happens I have to turn off/on wifi.. not good!.

I have the LTE version, but am running it without a data plan. I have the same issue with WIFI. The connection will hang after 30min to an hour of use. It is VERY annoying. I ran Speedtest, and i get an interesting result, over wifi i get a very fast download speed (15+Mb/s) but my upload totally hangs. It just sits there. On the same wifi, with my Galaxy Nexus, i have no problem with download or upload.
I've seen several threads across the internet about the problem, and no one seems to really know why. Some people say you need to change settings in your router, and it isnt the Galaxy 7.7's fault, but, i don't know if I buy that. I have the same problem at the Airport, and, i cannot exactly go and change the router config there. I am hoping that there will be an update to the firmware for the wireless radio, either separate or with ICS.

WIFI Problems Solved!!!
Hi,
I had the annoying wifi problem. It would work really fast for a few minutes and decide to stop working all of a sudden.
I fixed the problem by setting the maximum Router output to 54mbps G. Seems like the galaxy tab 7.7 does not like the N settings.
Now it works flawlessly and I will just use it at G speeds until Samsung provides an update. (I really do not notice the difference in speeds between G and N. Just the peace of mind that it will work every time.)
I hope that solves some of the other users' problems.

Wifi problems, yet another one...

Here's my problem, and I've seen many problems with wifi here and on other forums but nothing exactly like this.
When I'm at work, my phone connects to the network over there without any problem but, every time I come home, it simply shows my network as "Not in range", even at 2 feet away from the router (WPA PSK security). I've tried turning wifi off and on, resetting my router, "forgetting" my network on the phone. Nothing does the trick unless, I restart my phone and then it connects automatically and stays connected until I leave.
Something strange I noticed tonight; I went to my son's hockey game and, at the arena, I noticed it still showed as connected to my home network!?!?!!?
I started noticing this issue a few days ago, after flashing the 4.2.2 image from Google. My phone is rooted and is running the latest clockworkmod recovery but otherwise, still stock.
Something else I just noticed; my Nexus 7 doesn't have the same issue...
Anybody else having the same issue? Any hints on what's going on?

I also have this issue. But I had the problem before 4.2.2
Sent from my Nexus 4 using xda premium

Got to work this morning... wouldn't connect to the network here because... It was still connected at home, 40km away. That's a powerful router!
Any clues as to what might be the cause?
What brand/type of wireless router are you using? What type of security?
We gotta be more than 2 with this problem... I've seen so many issues with wifi with this phone on other threads... Weird

Last night I went to my parents and again, my phone wouldn't connect to their home network so, its definitely not my router. So I made a backup of all my apps and returned to 4.2.1 and voila, wifi problems are fixed, for now...

G2 Verizon - Wifi Won't Connect

Has anyone had any issues connecting to Wifi networks on their G2s? I got the verizon version on Saturday and haven't been able to get the phone working on 2 different wifi networks. I can connect to the wifi network just fine, but I can't access the internet at all. I can confirm that other devices are able to connect no problem.
Curious if anyone has some thoughts on how to potentially fix this. If not, will be heading back to Verizon to get a new one. Thanks in advance for the help.

I have the AT&T G2 version , it will connect to any wireless router but the connection will last 5 seconds then no internet, this is totally unacceptable I upgraded from the G-Pro and may go back as that never had this issue, I did read LG had a similar problem with the Nexus 4 and Optimus G

Mine works fine. I have a VZW G2 and an ATT G2 connected on the same router. It connects to both G and N networks.

No issues with my Verizon G2.

Did you try rebooting your router? I see this at home with the families iOS devices a lot, especially after heavy data traffic. I'll turn off the router for a couple hours or overnight and the next day all is well. Router is open, no encryption.

I have the exact same problem. It will sometimes transfer some data using browsers, but nothing on facebook, pandora, or the play store it will say connection lost or not data connection.
My wife has the same phone and it works no problem and also the laptop. Must be a dud wifi radio or something like that. Mine is going back to the store tomorrow.

Are you trying to use adblock by any chance? I was and it was causing the same issue you have. I uninstalled it and changed my proxy settings back to none and wifi is working great now.

Just received my LG G2 White brand new from T-Mobile about 2 hours ago. After many attempts to troubleshoot the issue it all failed. The problem is Wifi will connect to router and even work but after 30 seconds the connection goes down. The actual Wifi signal shows connected but no internet it gets stock. We tried resetting the phone and toggling with different features but still it did the same thing. T-Mobile is the worst they were trying to have me ship the phone back and leave me phone less for days. I complained and they are sending another one overnight but have charged me for the phone on my account. Mind you I've had months of bad service, after all I think I got a defective phone. I've read some other people having the same issue with other carriers. If I get another one with the same issue I'm jumping boat. If anyone knows of a work around let me know. I tried 2 different routers same issues connects then it randomly disconnects and stops downloading or transferring data.
Reset Phone - didn't work
Turned off mobile data - didn't work
Turned off wifi sleep - didn't work

I'm on Verizon. I have trouble with initial connection to wi-fi. It says obtaining IP address for a very long time. Even if I have a very strong signal. It takes about five minutes. It eventually connects and works fine. Then next time I try to connect to that router it works fine. It's only the first time I try to connect to a new router.

I just got this phone over the weekend and I was also having trouble connecting to my home wifi.
It would stay connected for 30 seconds or a couple of minutes then disconnect however the entire time the status under the Wi-Fi settings page says Connected even though I couldn't access the internet or the admin page of the router. Frustrating. If I turned off the mobile data, the wifi, the phone, the router, or some other unknown combination of events it would then reconnect again for another 30 seconds to a couple of minutes.
I called Verizon, they told me to take the phone back since I was within my 14 days. I did this and was optimistic. Then the new phone immediately experienced the same issue.
I did some more research, changed my router from 20 mhz channel width to auto 20/40 mhz. Not sure why it was set to just 20. I thought that would fix it. Nope.
I tried to set my phone to use a static IP, that didn't work either.
Then last night I tried the WPS Push Button option instead of using a password. This method worked and my phone stayed connected. I haven't had a chance to repeat my steps to verify it works again but wondering how other people are connecting, password, wps push button, wps pin? WPS is not my preferred option due to the security risks but just trying to track down what works and what doesn't.
I am able to connect at work just fine using a password.

I'm having a similar problem - my work network has no problem connecting while my home network almost never works with this phone (~25% of the time, other devices have no problem). Occasionally, resetting the phone or just turning on-and-off WiFi fixes the problem, but more often I just give up and use 4G. Anyway, if anyone finds a solution, please post! This is such a standard feature that should really work out of the box.
In case it helps, my home network uses "WPA/WPA2 PSK" security and my work connects to "802.1x EAP" security - also I'm not adverse to changing the security options if it fixes the problem.
Thanks! Nick

After reading more on this, I've decided this issue is router related not phone related.
I discovered my router reached end of life in April of this year is no longer receiving firmware updates. Newer versions of my router have received multiple updates since then.
I will be buying a new router. I report back on if it works.

I really don't think it is "router related" as all my other devices work as expected with my router. A new router may fix the problem, but I'm pretty sure the phone's WiFi is buggy and not the router..

In my situation it really appears to be how my router is handling the connection when I connect with a password since I can connect with limited security.
Does your router have a firmware update available for it? If so, have you applied it?

Received my new to me router yesterday with updated firmware as of 10/7/13.
My phone was connected for a few hours last night and I have not had any problems today. I'll report back if I start experiencing any issues but getting rid of my old, end of life router and replacing it with a newer router worked for me.
I did not buy a brand new router either. I went with a cradlepoint mbr95 which has been on the market for awhile and has already had a few firmware updates.

Check you wireless security settings
Had a similar issue to this and it seemingly was resolved when I moved the wireless router security over from WPA/WPA2 personal to WPA2 personal only. The phone found the WAP and connected right away. I tried to reproduce the behavior but alas I have not been able to do so. Perhaps this will help others.

hi guys
i found the problem
it happens just when you disable auto update in "settings>general>about phone>update center>software update>check automatically"
