Wi-fi not working

After connecting to 3 different wireless connections and none of then working, I'm concluded that my wifi isn't working.
I go to settings and check wifi on, it finds the network, connects, but I lose my entire data connection for the duration wifi is turned on!
Is anyone else having this problem?
Sent from my Samsung Vibrant

I'm having the same issues with the wifi. I downloaded wifi analyzer to make sure I was on a good channel. Set it to the best channel and my signal strength is 100%. I will be able to connect for a little bit but for some reason it goes in and out, connection unsuccessful, yada yada yada. I messed with all the troubleshooting solutions for my router (dgl-4300) but nothing works. If anyone can reply with a fix or point me in the right direction, that would be greatly appreciated.

Same Issues
Any help is greatly appreciated. Data working fine when on 3G but Wifi = no data. Connection is fine, IP is fine.
UPDATE: It's working again on my home WIFI. Will have to see if it's just an "at work" issue. Hopefully IT can assist.

Same problem with Verizon MiFi
I have had ZERO problems connecting to the Linksys access points we have setup at my home and my office, but recently my work provided me with a Verizon MiFi (as well as an iPad - don't hate ) and I've had MANY issues trying to get my Vibrant to consistently connect to the MiFi.
My iPad, Motorola Droid, and Laptop have no issues connecting to the MiFi.
On my Vibrant I'm running the 2.1 stock ROM with root & the latest ClockWork recovery.
It will "connect" to the MiFi (I use quotes because I can't really tell - it AT LEAST receives an IP). But I'm unable to send and receive data. I can't even browse to the MiFi's internal configuration page .
To FINALLY get it to connect consistently I have to do some kind of random combo toggling the wifi off and back on and then turning the MiFi off and back on and it will EVENTUALLY connect and stay connected with data flowing freely.
I've customized my configuration a little bit on the MiFi so I'm going to reset it back to factory and not change the config to see if it makes a difference - because at lunch I was able to connect to my boss' MiFi with no problem. I'm thinking it may either be the phone or the mifi...

I've connected to about 10 different wireless networks with NO issues, at all. The connectivity is actually much better than my G1/Nexus.
HOWEVER, last night at a bar I was connected to their wifi, strong signal, but I was not able to use Data. I was in a very poor reception area for T-Mobile... don't think that could be an issue, bit the other places I use wi-fi that is not the case.
I just chalked it up as a fluke and moved on. Not sure what was wrong.

I had this happen to me today. I just rebooted and it went away. Toggling wifi didn't help, but I only tried it once. The phone reboots so quick I figured I'd give it a try.

I have set the phone up manually with static ip. Seems like its a problem with the dhcp.

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 disconnects often?

I'm really happy with the phone so far, but my wifi disconnects fairly regularly and I keep getting a force close on the SMCC Process (whatever that is). Anyone else having problems?

I just read the thread below this and that issue seems similar.
EDIT: I tried turning off the smart wifi, but it still loses connection. The phone still shows that it's connected to whatever wifi signal, but stops downloading. This happens both at home and at work, so I don't believe it's related to the router itself.

I'm seeing the same issue on mine as well. Noticed it last night playing Pandora via wifi. Would play like 3 songs then nothing. I would have to toggle wifi on/off to get Pandora playing again.

Sounds like basically the same thing. If I wait long enough, it comes back on its own, but it's faster to just cycle wifi or airplane mode once. It's fairly frustrating, and I even found myself just using 3G to do things last night instead of Wifi.

seems to be a known issue in other S4 forums:

Mixed Mode WIFI
I had this exact same problem with my EVO 4G LTE, the problem was the mixed mode WIFI. (B,G,N). On the EVO it turned out to be an easy fix because there was a setting in the WIFI menu to force either B or G. As soon as I selected one mode I had a solid internet connection. The problem here is there does not seem to be an option in the S4 settings to allow this. I have been trying to force single mode on my router to see if that will fix it but my router will not allow me to turn it off either. Pretty serious bug I would say.

WIFI worthless on brand new S4

it doesn't do it as often as it did with the SGS3 though

I really wish I could find a resolution to this. I'm thinking of wiping my phone and starting over to make sure it isn't an app issue, but man that's a lot of work.

Im having the same issue as well.. Im almost positive its common issue and i would expect it to be addressed in the next OTA

The common link seems to be DLink router. We have a Cisco Linksys router and it stays hooked up solid on that.

I have an Asus router. Don't know if there are usually problems with those or not, but I haven't had any prior issues.

I have a Cisco e4200 stock and a Asus running ddwrt operating as a wireless bridge to extend my network. I had to turn off mixed mode on both devices to resolve the issue. Hope that helps.

I have the same problem but I have Netgear routers. The one at my house works fine, but at my other location. The wifi drops.

Same problem on dlink

Adding my 2 cents because I have 2 S4's that I've been testing with and I'm getting mixed results... my first post here so I hope I'm doing this right!
I have 2 wireless routers at home:
- DLink DIR-655
- One provided by my ISP (Bell Canada; not sure of the model at the moment)
The DIR-655 is troublesome for BOTH S4 devices; they stay connected for a few minutes (or longer in some cases) but will always end up not transferring data even though they show as having a very strong signal. Turning wifi on/off always fixes the issue for a short period of time.
Knowing that there seem to be compatibility issues with the S4 and DLink router, I switched them both over to the Bell router. Now only one of the devices has the wifi issue described above.
I found it odd that changing the router being used fixed the issue for one of the devices but not the other. I'm now questioning whether one device has a hardware issue or not (doubtful on this, but worth questioning).
Both S4's have the most up-to-date firmware as do all of the routers in the house. No other devices (iPhones, laptops, apple tv, etc...) have any issues with the wifi.
I've tried resetting the routers, forgetting the wifi connection and setting it back up, rebooting the phone, smashing my head against the wall; nothing seems to have worked permanently.
Is it possible that this is a hardware issue and not a software issue? Has anyone else had similar results with multiple devices?

fix....?
this wifi drops are due to the router WIFI signal setting. it will drop it you are using a B/G Mixed signal/ B/G/N Mixed signal. i recommend setting it on 802.11 g. or, if all your Devices in the house have N use N since it has more bandwidth. i use G because of the PS3
Hope this helps resolve the issue for you guys, it sure did for me.

Thanks for the suggestion, I can attest that this wasn't a permanent solution for me. After switching to N mode only, the amount of times the issue occurred was reduced, but still happens at least once per day.
It's also a pain when I'm connected to networks where I have no control over the wireless settings (work, public networks, friends networks).

I have a linksys modem and router. Haven't had a single connection issue with this phone as I had with my EVO. As my wifi disconnects and reconnects right away. Lol. First time that has happened. Knocked on wood.

wireless network problem

I have an AT&T galaxy s4 and I've been having trouble with the wireless. I can connect just fine to the netgear router at my apartment in Athens but at home I've been having trouble. At home we have AT&T uverse with an AT&T branded router. My phone will connect for a little while but eventually the small down arrow under the wireless symbol in the status bar starts blinking and the phone says it's connected but I don't have internet. Ive tried searching for a fix but it seems that the only routers people are having trouble with are dkink routers. The problem seems to trigger after I try to load a new site or refresh a page. Also, locking the phone triggers it as well. I've tried changing the security settings, forgetting the network and re-adding it, as well as turning the wireless network power saving option off but nothing works. I've rebooted the phone and the router but it still messes up. What's odd though is that my brothers galaxy s4 connects just fine (although I haven't been able to do extensive testing on his phone). Also, I was home last weekend and the weekend before and it worked just fine. I haven't rooted my phone or changed any settings that would have impacted the wifi since then. Anyone have any ideas?

I'm having very similar problems. When I connect to the wireless, the phone will work on it for about a minute and then stop getting to websites, etc. I have a Motorola SB 6121 cable modem with Vonage and a Dlink DIR-655 wireless modem. Inet provider is Comcast (only option here).
Anyone else having the same symptoms?
I've done the same troubleshooting steps: factory reset, power cycle, default settings, etc and the phone does the same thing.
EDIT: it's been working longer than usual now. I adjusted the Transmission Rate from the Wireless setup to 54 from Auto and the wireless has been stable much longer. See http://forum.xda-developers.com/showthread.php?t=2253471 for people sharing the same pain we have

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"
