[Q] Cannot connect to WiFi

For some reason, this morning my A500 will no longer connect to any WiFi AP.
If I go into WiFi settings, it just shows Scanning... Obtaining IP... Scanning... etc.
I've tried with multiple APs and have no luck. It worked yesterday just fine.
I have also tried rebooting it several times to no avail. Anything I can try to get it to work again.
(Side note: My DROID3 phone can connect to the APs with no problem.)

which firmware do you have ?

Search is your friend...

This happened to me just the other day. Rebooting didn't help, however two hard resets (paperclip in the reset hole near the USB port) in a row got Wifi working again.

Moving to Q&A.
PS: Every Q? thread should be posted in Q&A.

supposedly tthe updates are fixing this. Till then: if you haven't already, root your device with iconiaroot if you have 3.1. Then download a root file explorer, I recommend es file explorer, then go to settings and toggle the 2 root options. Turn off wifi, and in es navigate to data/misc/dhcp and delete the 2 files in there. (To get to the root of your file system press the picture of the memory card in es) then turn wifi back on.

HELP!! please :_ wifi stopped working after update

I have a US wifi only xoom
It has been rooted on android 3.1 stock for months with bigrush dogs kernel.
Today I decided to upgrade to 3.2 using solarnz hammerhead. So I performed a nandroid backup, booted back into cwm and then wiped, then flashed hammerhead and then proceeded to reboot. upon rebooting I was ask to connect to wifi and now I cannot connect to wifi for anything. Every network I try to connect to just says connecting or says nothing and never connects. So I flashed my nandroid backup to go back to normal and I still have the same issue. I can't connect to wifi. Anyone here know anything at all?
Thanks for you help
Wanted to post an update to this problem. Apparently when I flash a new update my system name changes in my routers Mac address settings. My router then automatically blocks my xooms Mac address so I had to unblock it in the router. Never experienced this with my evo. Fyi. I have a 2wire router with Att

I actually experienced the same problem the first time that I flashed hammerhead. I thought it was a fluke or had something to do with the wifi issues that I have had with all of the 3.2 roms, including stock 3.2 on the xoom and the transformer. I just flashed back to tiamat 1.1 wiped again and then reinstalled hammerhead. That did the trick for me.

Wireless "Disabled" - help

I just recently got this tablet from someone else. (This person had no problems and is trustworthy in reporting all that was done and care taken with it, even offering on advice on things you can do with it.)
My first step was to connect to Wifi. This happened without problems.
When returning home from work where I also connected, my wireless connection(s) said "Disabled" after trying to obtain the IP where they worked fine before. The first time this happened I had to do a factory reset to solve it (hardware reset didn't do it).
Today, it is happening again. I woke it from "standby" to start using again at home and received this message. In fact, any attempted WiFi connections comes up saying "disabled" after attempting to connect and obtain an IP. Again, these are saved connections that previously worked. I know for a fact that it's not the routers.
Please help if you can. I've tried:
1) power off/up 2x in a row to no avail
2) removing and adding back the connection with the appropriate passwords
3) a factory reset but I really don't want to do that again because I'm afraid flashing it back will bring back the same problem.
3) I haven't put any new apps on it since it last worked earlier today so I can't figure that as an issue. The first time it happened a week ago was when I'd just gotten it. It has worked for almost a week without problem. I did nothing special but travel home.
SPECS:
A500 Wifi
Rooted (was unrooted when it first happened); rooted now using IconiaRoot v1.3
(previously rooted and unrooted with Gingerbreak which would no longer root)
ROM: Honeycomb 3.1 with Virtuous Picasso v.1.1.0
Kernel: 2.6.36.4-UNITY-V5-ge7dee2a-dirty
Thanks in advance.

it's a known problem with this tablet when moving from one access poin to another, introduced with the update to 3.1. you have to reset using the pin hole near the micro USB port. i use a staple.
it may take a few tries. if it never works, there's a specific file you can delete if you're rooted. if you cant do that, you will have to do a device wipe.

There is a known issue of connecting to PEAP/EAP networks, which most work networks are. After connecting successfully, often many times, it will suddenly fail to connect. It also shows the signal from the access point to be very low or non-existent. After this happens, it can also cause problems with other PEAP/EAP access points as well.
If this is what happened to you, here's the fix. Try to connect to the access point giving you problems. While it is stuck on trying to connected, click the access point name and tell the tablet to Forget it. Then enter the same access point information manually and try to reconnect. This fixed my problem, and the fix sticks for a few weeks or so until it comes back.

Interesting, I had this same problem a few weeks ago when I visited my parents house. After a couple reboots it just started magically working again and didn't think anything of it. Their router is whatever the Verizon FiOS people install when you get their service.

Thanks, GeekGuy and Falkner, but.....
I've tried both before, but I went ahead and tried both of your recommendations again (pin reset and connection attempt/forget/add). Neither fixed it.
I would like to try to delete the file that Falkner mentioned, but you didn't specify a name and/or location of it. Can you share that?

I could never find what file to delete, so I've just installed a new ROM (thanks to XDA for info on all the how to stuff).
We'll see if it repeats.
Gone from V.Picasso v.1.1.10 with HC 3.1 to Taboonay 2.1 with HC 3.2.
Thanks for the attempted help!

Just guessing but I would say your problem is solved since no reply from yesterday?

Per my last post, I've switched ROMS. As it happened randomly before, I can only wait to see if it happens again. I will post back if it does.

And....as of tonight it happened again.
Note: Different ROM working since the last post 9-26-11.
ROM Taboonay 2.1
The only thing I can wonder about is if it happens when it tries to connect to a network that is actually down such that it cannot obtain an IP that actually gets internet access. However, it was "disabled" when I brought it up before ever trying to specifically reconnect to a network to realize the ISP wasn't doing their part.
Still....no reboots, or hardware resets have worked. I'm working on an image restore of only the system from the 9.25 install of the ROM rather than a factory data reset. Not sure if that would have been better. Trying to save some of what I've done recently. Gonna have to get used to a weekly backup if this is to continue.
Grrrrr..........restoring a backup turned out to be the last ROM. After reinstalling Taboonay 2.1, I still had all my apps and found the same problem. I'm doing a factory data reset as it's the only thing that fixed it before :-(
The only "oddity" I've experienced has been since last Thursday. The Android Market doesn't even recognize now that I have another device. Have communicated with them; they are investigating and saying they have received reports of this on free downloads giving an "unable to process purchase" message. It updates installed apps, but I cannot download any new ones through market, appbrain -even the appbrain app only and not to the market app. I can download through Amazon, so it's the Market issue. Still, that shouldn't affect this issue.
If you have any constructive feedback, I'd appreciate it!

This was happening to me. I had problems with every rom I tried until the following combo: Taboonay 2.2 with Richard's Villain ROM 3.7 kernel. Every other combo would lead to erratic wifi...now it hasn't happened in 2 days. I don't know why this is happening as many of the roms I tried claim to have the wifi fix integrated. I hope this helps. Just flash the latest Taboonay and then the kernel zip file on too of it. By the way, latest rabbinate is 2.2....NOT THE ONE YOU HAVE NOW.

Wifi not working?

So I dont exactly know what is going on. I go to connect to a wireless network and it will start to connect, say its obtaining IP adress, and then refresh and start all over again. It never actually connects and stays connected. I know its not the router because I have tried numerous networks (that worked before) and now they just stopped working. I did have trouble with root and I re unlocked the tablet because root wasn't working. Is there anyway I messed something up? I installed the 3.2.2 rooted rom and now I flashed back to moray both with the same non-working wifi result.
Anyone know what is going on?

Did you by chance restore system apps and data through Titanium Backup? Sometimes wifi is messed up by restoring a previous version of the system app and data over a newer version supplied by a custom Rom.
You might want to just wipe everything in recovery, reflash your Rom and set it all up again fresh.

my WIFI was messed up when I swiched Kernels way back. I had forgotten to push one of the files... when you switched ROMs, did you wipe first or did you just install one over the other?

have similar issue after going from hammerhead 3.2 to moray 2.2.2.
Infrastructures wifi works fine, but whe trying to connect the xoom to an ad-hoc (from Nokia jokiuspot) just keeps displaying "obtaining IP address". Never had a problem with hammerhead? Guessing it has something to do with the dchp client on the Xoom¿
Certainly not a big problem, and something I am more than happy to live with as is.
everything else working spot on. Using a UK wifi only!

Wifi Turning on Stuck

UPDATE - Problem sorted via philos64 thread at the top...
Should've tried that 1st, but posted here hoping someone would confirm that was the route to take, as it wasn't actually bricked... Never mind, all done..
Why??? Was out earlier so I turned my wi-fi off and my mobile on and everything was working fine..
When I got home, I turned the mobile off and tried to turn wifi back on, but it is hanging on 'Turning wifi On.'
Tried rebooted the tablet a few times and rebooting the router, (BT HomeHub 3), but still the same problem.
This N7 is rooted and running 4.2.2.
When I look at the Advanced Wifi the MAC and IP address are unavailable.
When I go into Wifi Analyzer it says the wifi needs to be turned on and tries but gets same hang and retries...
On the left of the analyzer it shows my Wifi ID with a mac address underneath with a yellow triangle and 'No Signal!' in red.
The wifi from the router is working as my phone is connected via wifi.
Any ideas please people ???
:crying:

going for the post with the most views and zero replies is not on my bucket list... So I'm going to reply to myself..
An Update....
The problem is still there, so I went into bootloader - recovery mode....Then I went into Android system Recovery.
I selected cache then wipe dta/factory reset.. Reboot then starts tablet as new with the unlocked symbol, then goes through the initial setup. Select language, then it does Select wifi and displays 'Turning on wifi'.. Hung...
Would flashing it via Nexus root toolkit sort out then problem... If so, any clues what flash and how...
If it wouldn't fix it... Is the tablet now bricked??
Please answer someone if you know..
Cheers

There have been several posts about wi-fi problems if the outer shell of the N7 is separated and not fully locked in. A loose or separated shell can cause a disconnect in the wi-fi antenna. Check for any separation and maybe squeeze the front and back together all the way around the outer edge.

I did read them and a lot of other threads but they were mainly to do with wi-fi looping and not connecting.... I couldn't find any other post regarding just 'turning it on'.... And seeing as it's sorted with just a flash of the stock rom, I can safely assume this problem had nothing to do with hardware...
Hence why I was surprised I was the only 1 with this 'type' of prob.... (but I didn't read every post so I may have missed one).

Same problem too

im experiencing the same thing. im using Samsung galaxy S4 i9505 LTE and on android 4.3/ rooted Baseband i9505XXUEMJ5. it happened when i was trying to erase all the bloatware on my phone using Trulyclean by schoolsux. after i flashed the script i started having this problem.so far ive tried to do a factory reset by using custom recovery, tried to download the modem fix and flashed it through odin and do the advanced settings on wifi and uncheck the auto network switch. The problem that i have is yes it say "connecting" for 2-3 minutes then it gives you a list of possible wifi connections and then you connect. another 2-3 minutes then it wont connect. repeat the steps and now i can connect, then if you turn off the wifi you will have to go through the whole process again. it doesnt save any wifi connections you have connected before. there are 2 other ways i havnt tried yet and that is to flash a different kernel. a custom kernel and reflashing my phone again with the android 4.3 then root:laugh: for the nth time already:fingers-crossed:

i have same issue with htc one x, my wifi doesn't wan't to turn on. it stuck on "turning on...", i tried to flash different roms, etc, now i think about flashing kernel, did you do that? did it help?

Same problem on N4
Have had the exact same problem not once but twice. One day it works perfectly fine. Next day, it just stops at turning on process.
On my N4 the 4.2 was working fine. Along comes the 4.3 OTA update and the wifi stops working. Does not startup or show the mac addr either.
Did factory reset, wipe cache and even reflash binary from google stock images. No relief.
One day, the wife using gmaps started the gps location service and pop the wifi started,
Now after the 4.4 OTA all seemed to work well till yesterday and pop the wifi breaks down. the earlier trick of gmaps does not seem to work. I think one of the google apps update is breaking this.
After rebooting also, the device seems to remember the wifi state and tries to read the previous history and restore for the startup. And that is killing.
Any idea how to debug this or to wipe the wifi logs or to manually start the wifi/bluetooth radio.. ya athe bluetooth is also stuck.
Thanks guys in advance

Where is the fix?

Hi Can you please send a link for the solution? i am still stuck with "wifi turning on" screen and cant seem to bypass it. No matter what Stock image i flash through Wug Toolkit.

i have got the same wifi errorrigictsi vanished
initially i had loaded my explorer with fly rom and everything waas working except the internal memory. i'm not even able to download at least an app and then i tried bulletsense rom for increasing the internal memory of my explorer. it's successful, and the memory increased. From there onwards, the problem started. the wifi first said error... but after reboot, it's all the time saying "turning on"..
by typing "ifconfing twlan0" it said no devices found... so i thought it might be some driver error. coueld any one port some other drivers to the below rom so that i can have both internal memory and wifi...
link to bulletsense rom ///d-h.st/xFr//// ( add https before /xxxx/)
here is a screenshot of it...///bit.ly/MMSeam///
any one please help me on this and give me a chance to raise your thanks meter...
sorry that i'm newbie and not allowed to post links.

Hey guys.. I faced similar issue in my AMOI 820 based Indian local device Micromax (rooted + custom kernal)
I fixed this stuck wifi problem by uninstalling Google apps in system by removing them using Titanium back up + and again installing them from playstore if needed.. Hangouts(in my case) if it's a system app after getting updated is the culprit .. Try removing it and reboot and test it yourself..

guess it working now!!
I was going crazy about this stuck wifi issue!!
I tried everything!! I found on the advance panel on the wifi
That the MAC address and the IP address is unavailble.
After many tries i think i fixed it!! Using:
Busybox and MacMan
MacMan changed my MAC address and now the wifi is no longer stuck!!!! Hope it will help you too. Peace
