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.

Help with fixing Wi-Fi

I have reached my wit's end trying to resolve my problems, so I'm posting here for ideas on fixing this, any input is appreciated!
When this started I was on stock, rooted, ICS 4.0.3 and had been for months. My wife has a nexus s with the same config and hers works fine.
Last week, my daughters sidekick 4G stopped having wi-fi internet connectivity. I turned her wi-fi off, then back on and it was fine and has been ever since. Later that night, my nexus did the same thing, the same procedure resolved it. Ever since then, my wi-fi will only work for 1-5 minutes after turning the wi-fi on. This is the only thing I can think of that changed that could have caused this. This was the first night we connected her sidekick to wi-fi.
The wifi symbol is up there, it'll be blue for up to half an hour, but won't have internet connectivity for long. One thing I noticed pretty quickly was that even though the grey wi-fi symbol is there, I can't access the router settings at 192.168.1.1 from the phone. I thought the grey wifi symbol still indicated I was connected to the router still, but it's not working. Each time this happens, I can turn wi-fi off, back on immediately and it'll work for 1-5 minutes. It appears that the more I constantly use it after turning it back on, it seems to maintain connectivity longer.
Last weekend, just after these issues started, I visited my sister and my phone operated on her wi-fi all weekend just fine.
When I came back home, my problems started immediately.
Here's what I've tried in pretty much the order I tried them:
I started by uninstalling avast, facebook, and autostarts
selected "Forget network" in access points screen and reconnected
Factory reset
Wipe dalvik cache & fix permissions
see if it worked without sim card in (it didn't)
flash GB broadcom driver
Switched router channel from 6 to 1
flash stock 2.3.6 (wi-fi problems still present)
flash OTA ICS (still had problems)
flash stock 2.3.6
flash OTA ICS
re-root
Flash PixelROM 1.60 LiteTouch
factory reset router (No wifi problems on using open network and default SSID for 30 minutes!)
resetup WPA Personal security and rename SSID same as before
Worked for another 15 minutes or so after this
flashed stock 2.3.6
flashed OTA ICS
re-rooted
Restored nandroid backup - quit working after this step
Factory reset router - worked for about 15 minutes, I decided I was ok so I setup security and SSID as before, then it quit working again
flashed PixelRom 1.60 LiteTouch
flashed stock 2.3.6
Flashed OTA ICS - THIS time I did not restore my google backups from the cloud, fearing that this was somehow restoring something that was causing me problems. It did not help.
Changed SSID on my router and reconnected phone
I have spent countless hours trying to fix this. I don't believe it's the hardware because the router factory reset seems to help quite a bit, works fine on unencrypted default router settings, and it worked on my sister's wi-fi.
I have nmap and wireshark and have a basic working knowledge of them. I have adb setup and usable on my computer. I also have dd-wrt installed on my router and have for years. Is there any kind of IP or hardware logging I could perform with these tools to help figure out what's going on??? ANY help is GREATLY appreciated!!

Well i'm no expert with any of this, but it sounds more like a router issue.. If both your sidekick and nexus have the same characteristics of failing wifi, it cant be the devices..
If you've already reset your router and it does the same exact thing, maybe it is something wrong with the router itself. You said it connected fine at your sisters house, so it cant be any hardware within the phone.. The only thing I could think of is maybe try a different router in your house to see if it works? If that helps get rid of the connectivity issue, then you can just get a new router and be happy with the wifis

I don't think a *hardware* problem with the router would only affect 1 device connecting to it wirelessly. I would think that kind of issue would affect all devices on the network.
Which makes me wonder if there's a setting on the router that may be causing it somehow, or some combination of packets might somehow cause the router to block my phone.
But again, I'm open to ideas here and I appreciate your input. I think getting another router will be my next step if I don't hear anything better by the time I get my next paycheck.

Ohh, I thought you had said that both the sidekick and nexus were having problems connecting. My bad.
But yeah have you changed any settings on it lately? Or messed with anything related to the router? Some setting may be kicking your device off after 5 mins, maybe some frequency setting or something dumb like that, I have no clue.
I know how it feels to have funky wifi, so I was only trying to help. good luck

Have you removed DD-WRT from your Wireless Router and back to stock OS? I had a Linksys router with DD-WRT and after about 3 years it started working so weird it became useless with any device. Had to buy a new one.
BTW, are other devices connecting fine to this router?
As swamp goblin stated, I would try with a new router.

It sounds like an issue on your router (or AP) with mixed client settings. I have had this issue with an old Netgear AP.
Try forcing "WPA2 with AES only" if all clients support it, otherwise force "WPA with TKIP only". If you have mixed B/G/N devices, force the fastest mode that all devices support. I use "G only".
Then remove and re-add the router on all your devices.
Also check for router firmware updates, and if you use DD-WRT firmware, find the Wiki page for your model and revision and use the suggested build there. The DD-WRT database they have is a mess and should not be used!

I haven't removed it. I thought I had a model that couldn't go back to stock, but I WILL be looking into this. The other devices connecting fine are Sidekick 4G, Wife's Nexus S, Acer Aspire one, HP tx2000 laptop, and my wife's HP laptop. I also have my satellite receiver connected via ethernet.

THIS FIXED IT! I tried it first since it was the simplest solution and I've been 4 days with no loss of connectivity since I changed it to AES only, which all my clients do support! Thanks so much!

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.

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....
-Matt

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 connection drops, have to reboot - Virgin hotspot

My Nexus 7 had no problem with wifi connections since I bought in right after they were first released. Last week, I bought a Virgin Broadband Mobile Hotspot to use while doing some traveling. (In some areas, it works a lot better than I expected.) The problem is that fairly frequently, the connection drops and I can't reconnect. When reselecting the device (or any other network) in the list of available wifi networks, I get an error message that reads "failed to connect to network." My only recourse is to reboot. A fast reboot is good enough, but I've done plenty of those and complete reboots.
Then, I can reconnect. That new connection may last ten minutes or many hours. But at some point, the connection will drop and I'll have to reboot to get another one.
I figured this must be related to the Virgin hardware, but when I got home yesterday, I discovered that this happened again with my router. In the 5 months I've had the Nexus 7, I've never had a problem connecting to my home router. So I "forgot" my remembered wifi networks and reestablished them. There are only two, my home router and the Virgin device. Didn't help. Right now, I don't have the Virgin device turned on, so maybe this will temporarily solve the problem. I'm not sure, yet.
One thing that seemed to help was that when driving and using the Google Navigation app, this seemed to be less of an issue. It's even possible that we never dropped a connection while navigation was active. When nav is active, the device doesn't sleep. So there may be some relation there. But plenty of connections were dropped while nav was off and the device was awake. In fact, most drops occur when I'm stationary, i.e., not in a moving car or walking around.
Another piece of info — our other Nexus 7, which also came along on the trip, doesn't seem to have this problem, but it didn't get used that much, so it may be that it would be there, we just didn't have the opportunity to see it happen.
Anyone seen anything like this and/or have any ideas about what to do about it? Why would I need to reboot to renew a connection?

I had a similar issue,it would see connections not connect automaticly and when trying to manually connect it would disappear.I shut off the autoscan for networks off and it works much better.
Hope this helps

Thanks. I'll play with that and see what happens.

The nexus 7 that I purchased for my wife last week is experiencing the similar issue. I can see many network in range but any connect I try to connect will return a message "failed to connect to network".
I found some submitted issues on the Android project thread, but none of them offered any solution.

It's your router, not your phone(s). Can't believe you haven't considered the common factor.
There's nothing wrong with the WiFi on these phones. Hence you can't find answers to problems that don't exist...

I have no problem with wifi whenever I change new mobile phone . In your case you can try resetting your router.

I have reset the router and like I said in my earlier post, the problem was not just in my house with my wifi, its every wifi we have tried in different places all over

There isn't nearly enough data here to make any sort of assessment.
-Have you tested your connection settings from the phone? Try something like Speed Test to see if it can establish a connection.
-Does Wi-Fi stay connected or does it drop in and out? Does the Wi-Fi icon change to being grayed out? Does it turn itself off under your settings?
-Have you tried changing the connection type on the router? WPA2 to WEP, etc...
-Have you verified that the network is broadcasting an Internet connection from another device?
-Can you see the phone on your network from a computer?
-Have you tried pinging an IP address from your phone?
More than likely it's a DNS or DHCP issue. But I don't want to recommend any troubleshooting methods until the problem has been isolated.

I have the same issue. I have had the phone for a month with no issues. The last couple of days, I can't stay connected to any wifi either. It has happened on multiple routers in multiple locations.
I have updated my router firmware (although it happens on all wifi routers). I get a connection, then it disconnects, finds the wifi again, and reconnects...over and over again.
Something is up.
Did a factory reset...wiped everything to start over again...didn't help.
