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.

Vibrant wifi problems

Hey guys, newbie user and android owner.
I picked up the vibrant the other day. So far its rooted, android-wifi-tether, and i performed the gps fix on it.
I really like the phone, but whenever I connect to my wifi router, it stops all data (android market, web browser, etc) It says connected and doesn't show any signs of problems. Am I doing something wrong?
Thanks for any help you can throw my way.

Hmm. Mine has problems with "No Connection" when it's connected to my wireless at home, but I just figured it was my router's fault since my computer gives me the "unable to load web page" thing all the time too. My router sucks, though. Maybe your does too?

Yeah, mine does it sometimes too. I just turn on airplane mode, and turn it back off...works fine after that. Its a hit or miss issue.

Mine works fine running off if my router. Btw, do you actually have the wi-fi tether working? Because I thought we needed a working kernal for that to work.
Feeling Vibrant on xda-app

Yup that did it for me. All I had to do was turn on airplane mode and then turn it back off. Wifi working for me now. Thanks.

Please tell us how you got wifi tethering to work without a custom kernel.

you know, i have a similar issue, where im connected to my router but i dont get internet and 3g goes away the moment i connect to wifi... airplane mode didnt help tho... its interesting really..
ive tried other routers and my phone can get wifi w/internet from them
i did factory reset on my phone 3 times trying to figure this out; 2 of the three times i got wifi to work w/internet until i disconnected and connected again. then i just got the same problem all over again

Nexus 4 WiFi Problem

I rooted and flashed my phone last night and everything was fine other than 1 thing. The Wi-Fi wouldn't connect on my home router. I tried several different roms and was left with the same problem where it was stuck on either obtaining ip address or authenticating. I then came into work this morning and the phone connected to my Wi-Fi network straight away.
Does anyone know how I can get around this problem, don't want to be using up all my data at home!
Thanks in advance

Dont get me wrong but did you try to restart the Router?

I second the other suggestion. Those symptoms sound like your router needs a restart if it hangs at getting IP/authenticating.

I'm having the same problem on the network at my university.

I'm having problems with my wifi as well. We have a network here at my office secured with WEP. My galaxy nexus connects to it just fine but my Nexus 4 refuses. It sees the network, show strong signal but it doesn't seem to connect. I did manage to get it to connect once and I downloaded some updates but then the connection dropped and will not reconnect. I've tried various advanced settings (forcing the network to 2.4GHz, changing the power options, etc... No joy. This is particularly frustrating for me as my micro sim has not yet arrived so WiFi is all I have Hopefully it will work at home. At least there I have access to the router so I can make changes if needed. So far not a fan though.

I've got WiFi problems here, too. Roaming between different WiFi networks (home and university) often results in an non functional WiFi connection. Experienced this problem with stock Android 4.2 on Nexus 4 and Galaxy Nexus and latest CM 10.1 nightly on Nexus 4. Even reboot doesn't help every time.
As workaround: If WiFi connection is broken, turn on "flight mode", wait a few seconds and turn it off again. Works for me, maybe it works for your problems too.

I literally just received my nexus 4, and I haven't done anything with the SIM card yet, I just wanted to get things going on WiFi to start. It sees the network I want, let's me type in the password, and lets me click connect. After that it does literally nothing. No thinking, no obtaining IP address, nothing. Any ideas?

I have exactly the same problem. Got the phone today and have tried several different access points - no luck. Restart the phone, no change.
Also, system updates screen said I could only download the update to 4.2 from a wifi connection till the 7th, so i set the date to the 7th and did the update successfully over the cell connection. Still no WiFi. Factory reset - no change.

Oh, also tried the flight mode "trick" with no success.

Your uni wifi probably is LEAP wifi or PEAP wifi, which is proven broken in Android 4.2

My university provides both LEAP and PEAP authentication. LEAP doesn't work for me either. But PEAP works. I'm able to connect via PEAP. (Stock 4.2 / 4.2.1 and CM 10.1)

Here is my log. It appears the authentication is timing out.
12-07 10:42:43.863: I/wpa_supplicant(19563): wlan0: Authentication with xx:xx:xx:xx:xx:xx timed out.
12-07 10:42:45.345: I/wpa_supplicant(19563): wlan0: Trying to associate with xx:xx:xx:xx:xx:xx (SSID='XXXXX' freq=2447 MHz)

12-07 10:42:55.346: I/wpa_supplicant(19563): wlan0: Authentication with xx:xx:xx:xx:xx:xx timed out.
All other devices do connect fine and I even restarted the AP to make sure.

This is getting very frustrating. I couldn't connect to wifi at work (WEP, I know...) at all yesterday. I went home, and my WPA2 network at home worked perfectly. I come in this morning and boom, I'm connected just fine to the wifi here at work (the connection was remembered from my tries yesterday). I went to lunch, came back, no wifi. Reboots, reconnections, nothing seems to work. I also have a Galaxy Nexus with 4.2.1 and it connects to the wifi just fine. Grumble grumble....

I did a few tests today and it seems to be only when using WPA2 with a pre-shared key. WPA works, as do open AP's.

No solution with stock google image AFAIK, because google does not provide 4.1.2 image for Nexus 4. You can try other custom ROM or ask if some one has successful LEAP wifi story about running custom ROM.
BTW I don't own Nexus 4, I am stilling using Galaxy Nexus, as soon as I upgraded to 4.2 LEAP wifi broke, I flash 4.1.2 back then it works fine.

I found that upgrading the access point (MikroTik) to the latest version allows me to connect.
Seems something in this device does not like some older WPA2 versions?

My N4 has been connecting fine to my home router over the past two days. Suddenly, today, it stopped recognizing the network (shown as "not in range" in wifi settings). No amount of router or phone reboots would get it to connect. I read in another forum about going to Displays in the settings menu, scroll to bottom - Wireless Displays. Turn on and search for wireless displays, then turn off. I thought, wtf? Anyway, I tried this and it connected to wifi immediately. Maybe there's a bug in the wireless display function that's interfering with wifi.

I am actually having a similar issue as others here, but I have found another weird work-around. Basically, although the Nexus 4 see's my campus's network, no packets get transfered back and forth, and I am not even sure what is going on (The IP address, tho, is usually "unknown".) However, upon going to the campus's IT help today, they turned off mobile data, and it then seemed to connect fine over Wifi. Any idea what is going on here?
There is no "signing in" to the network at my university, it just connects and verifies your device's MAC address, so I don't think they are doing any fancy authentication. I was thinking about maybe flashing a different ROM and seeing if I get different results.

i got mine yesterday and it connects then stops connecting after a couple seconds

I get exactly the same issue in my office. I can connect to school open network, but after a few minutes it lost connection (while still showing connected). I got to wifi setting, it shows that there is only one wifi hotspot and i am connected to it. But actually there should be more than five hotspot! If i switch wifi off and back on it can detect all the networks and get connected again, but then it goes to the weird cycle over and over.
Strangely, if i stayed in another office, it is connected all the time. Seems like the signal problem in my office. But i got no problem in my office when i was using galaxy nexus.
I am driven crazy by this!

Wifi Issue

So I got the Nexus 7 today from Amazon, did the setup, connected to wifi and had no issues. Very soon after, the Wifi showed it was still connected, but I couldn't update apps, go on the browser, get emails, etc. It looks like the Wifi is connected, but nothing that requires a connection is working. I tried factory resetting, but nothing helped. Has anyone else come across this issue? And ideas on what might be the problem?

Had that same issue. Rebooting my router fixed it for me.

Are you using 5ghz? 2.4?
I've been traveling all week and had no problems with my home 2.4/5ghz Linksys router nor any hotel access points I've used. Seems to work great. So you can't get online at all? No browser, no email, no apps, no play store, etc?
Perhaps you typed your password in wrong. What about router security?

Mine was doing some crazy stuff like that as well.
I rebooted the device and haven't seen that since.

I finally got it to work. All it took was me disconnecting from the Wifi and reconnecting again. Seemed like a weird little glitch, but all is good now. Thanks guys.

even turning on/off wifi multiple times i still get OP error, whos blue wifi icon connetion but i can't do anything online!!! i'll try to reboot nex7

Hello,
Try to change wifi router security settings wpa, wpa2.

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"
