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

I'm puzzled by the behavior of my phone. For probably a week at a time, I go to work, connect to a WIFI there, then come home, connect to a WIFI there. No problems at all.
Then it seems like after a week or so of 'being good' sometimes I'll wake up the phone and it will see the network, but will not connect to it, asks for passphrase repeatedly (WPA2-AES Cisco E3000 router) but just will not connect. I have found no way to trigger the phone to reconnect (and I refuse to do another hard reset because that is no solution at all).
The simple fix is to reboot the router. Presto, the phone will connect almost immediately.
I am willing to accept that maybe something is wrong with my router, although I have 3 laptops and a couple of IP cameras, and an Xbox that connect wirelessly all the time, and I never ever see this refusal to connect on any of those devices, and my wife's Blackberry will also connect whenever. So I'm thinking its my phone.
So for the experts out there, what is it about rebooting the router that fixes the problem?
I only recently learned how to get into the manufacturer's special app, so I'm going to pay attention to my IP address next time I have an issue, and see if it actually changes when I reboot after this problem occurs again.
Where does one discover how and what can be tweaked in the secret app? I'm cautious but not afraid....hey, I've edited the windows registry countless times on my PC and never toasted the OS yet! Does that count for something?
Add: I had this happen once at my work WIFI, using an ancient DLink router using WEP. At the time, I was trying out a bluetooth headset (Plantronics Backbeat), which worked, albeit, after I was done listening to the podcast, be darned if I didn't get into this refusal to connect thing, and unbeknownst to me, I was using the 3G data connection for what I thought was a wifi broadcast. That sucked 175 megs that day! I was a bit pissed about that. I have not used the Bluetooth since then.
Rebooting my router at work fixed the problem but I hate doing that, because I've got other equipment on that network that likes to be permanently connected.
the same happened to a frined of mine: interoperability issues with that model of router and the phone, changed the router and after everything worked perfectly, that sucks, but it is
Had a similar problem, and simply could not pinpoint the cause. Solution? I resetted my router to factory settings, and started to change all the settings from scratch to my desired settings. One thing that helped solve my problem was that I changed the default IP address used by the router (in my case, 192.168.0.1) as well as the IP range to something more ... random. Also, I limited the number of allowed IPs to 10 rather than the default 100...That helped. Never got a disconnect or problem connecting again. I had the same thing happen on my mother's iPhone and my brother's Galaxy S, and this solved it.
Hey everyone. I just recently picked up this tablet. Its the Verizon 4G version, but 4G isnt active right now so Im using WiFi only.
I can connect to wifi no problem, but as soon as I launch the play store the wifi drops. If I exit, go into the settings for the play store, etc... WiFi turns back on.
Any ideas?
Anyone? Ive noticed now that it seems to be happening using browser or opera too. Last night I powered te tablet off, rebooted my router and fired the tablet back up and it seemed to work for a bit. Im not too keen on having to do this each time, however.
Haven't experienced this at all. Try a wipe? Clear play store data? <-- doubt that would help but who knows.
Well the fact that its extended beyond the play store and into browsers bugs me.
I performed a wipe - no success. I started googling galaxy tab wireless issues and there are posts everywhere, but most were for the 10.1 tab it seems.
Interestingly enough, if I switch to 5GHz on my dual band router, it seems to work fine... but the 5GHz signal is so weak that the tab randomly drops it. It seems to be the 2.4GHz band that being a pain in the neck.
Interestingly enough, my old iPad has no issues with either band in any applications.
Wifi Issue
I just received my galaxy tab7.7 2 days ago and it seems that I'm also having the same problem. After reading online I realised that certain routers don't work well with it. I am not sure about the exact problem but next day I connected my tab to university network and it worked absolutely fine. I don't know if there are certain models which are having this problem or if all 3G versions have this issue. But I may write it up to samsung later to find out more. You can download an app e.g, Speedtest.net from google market and check if your network does work with it or not.
I use intel my-wifi to connect it to my laptop's network, it works fine for first few minutes but then my-wifi shows that tab isn't connect to it anymore whereas my tab shows it's connected to the inernet but doesn't open any page, email etc.
no such behavior from my tablet in last 45 days or so .
try factory setting ....

I've already tried it a number of times but no improvement.....
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...
Hey guys. This is my first post here. Checked all the troubleshooting threads and did not see this. Have seen the issue similar on other forums and sections, but my situation is a little different.
I have a rooted 16GB S4. I have been using the same wifi connection since August 2nd. The wifi on my phone, computer, TV, and Xbox have all been working this whole time. This afternoon I tried to check something on my computer and had no internet connection, but was using my phone. Thought the issue was my computer. Left. Came home. Computer is connected fine. My phone, my wife's iPhone 4s, TV, and Xbox will not connect to the network at all. So this situation is a bit different as I have been connected for 3 weeks and now wont work. I assume its not my phone because so many other devices dont work either. Not to mention it's both IOS and Android. Anybody have any ideas? Thanks a lot.
My plus is just something small. Yesterday my lock screen blanked out. I have my other lock screen pages, but my page with the date and time and all just randomly went blank and will not come back after reset.
If I read everything correctly then you don't have an issue with any of your devices. Chances are it's your wireless router. I would recommend replacing it to see if that fixes the issue. You can always buy one from Best Buy and take it back if that doesn't fix your issue.
EDIT: Forgot to mention that it may be the way your router is configured. (I doubt it's your ISP if something is working but other stuff isn't.) What kind of router do you have?

I think its a netgear. We are living in a downstairs apartment. All my devices now work. It was weird. First nothing was on. Then just the cimputer. We went to sleep and woke up and phones were working but not tv or xbox or computer. Now everything is fine again.... I did send an email to my landlord and ask her to unplug the router for about 30 seconds. She may have done that....
I definitely think it's the router. Netgear isn't the best around, and I have found that they do have problems from time to time. If you had access to the router yourself that would be the best way to troubleshoot the issues.

If things were working fine for some time then just started acting wonky, it wasn't anything your devices (S4, iPhone, computer or xbox) could've done, per se. Something had to have changed with the router - not that it's going bad or that it sucks, but something was altered. The smallest changes in networking can make the biggest difference. Don't just buy new devices and throw out the old when an issue arrives.
That's great its working now. For future reference, you should get your own in-apartment WiFi, like "Clear", cheap and works well in most areas, this would narrow down your possibilities of your internet not working properly on your S4 and other devices.
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..
Sent from my VS980 4G using XDA Premium 4 mobile app
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"
