I just picked up my phone and started fiddling around with it, and I discovered that the WiFi just doesn't work right anymore. It connects to the access point just fine, but when I try to go to a website, it acts as though I don't have a connection at all. I have no idea why this is happening, but I recently used ICS Control to replace my internet connection while my modem was messed up, and the phone heated up quite a bit. However, the WiFi connection to my phone was working just fine the whole time, it never disconnected, so I think it's some settings that ICS Control might have messed with.
So, I tried deleting settings the my access point in the WiFi settings screen and reconnecting to the router, but that didn't work. I also tried soft resetting my phone, but that didn't work either. I don't want to hard reset it right now because I don't feel like losing my settings, yet it seems that I might have to try that too. I need some backup software.
I haven't tried using my phone as an access point again, but I get the feeling that'll actually work, so I have no idea what to do. Should I try reinstalling the radio or something? What the hell could have caused this? It just broke on its own.
I bet you have a software problem with something you installed. A hard reset is probably the best choice.
Okay, is there some good free backup software I can use to backup everything, including contacts, apps, settings, etc? I'll do it, but I don't want to have to change every little thing.
Also, the only things that I think could have caused this are either ICS Control or WmWiFiRouter or whatever it's called. I uninstalled the latter before installing ICS Control and I love it, but I dunno if WMWFR might have messed something up.
spb backup
When I go into the settings to enable wifi I get the following messages back to back, either one can show up first:
"unable to save the network"
"unable to scan networks"
When this started the phone was not rooted.
I rooted the phone in an attempt to fix this.
I deleted /etc/wifi/wpa_supplicant.conf after backing it up.
This fix was suggested in the EVO forum, however it did not work for me, also the wpa_supplicant.conf was not recreated, and I was under the impression that it would be.
Has anyone had this issue and fixed it without doing a factory reset?

Now that you are rooted, i would say do a nandroid backup, then do a factory reset to see if that fixes your issue, if not, then you have a backup to restore to incase it does not work, if it does, then your good to go, if not restore and you are no worse off.

How do you do a NANDROID backup? Using Koush's recovery image? I saw initial unstability issues so didn't bother with it. I'm still hoping to see Amon Ra's recovery.
oh jeez i'm glad this thread is here. I have the exact same problem now. I don't remember anything significant enough to screw up the wifi, but I did use XBMC and Allshare as a trial run and it worked fine and I was amazed.
The next day the wifi is gone and 'unable to scan networks' gets on.
Can somebody help with this issue?
I will nandroid back soon and see how it goes down.

that is a link to the how to, just follow the first post, once you have clockwork recovery installed do a nandroid back up through ROM Manager,(if that is the koush recovery you said you had your set, just install the app) try a factory reset after backup and see if that fixes your problem, if it does then your set, if it does not fix it, then you can always do a restore and it will put your phone right back to how you had it when you did the back up.
Just ensure that you dont partition your sdcard with the rom manager, it will wipe your whole phone internal sdcard, not the external one, you should have no reason to do this anyways, just wanted to let you know not to try for fun. as it is not one of the steps to backup or restore anyways.
I had the same problem and found that the problem seems to stem from Allshare. I used it briefly and disconnected from WiFi, later that night, I enabled WiFi and had this problem. Today I opened Allshare and it prompted me to turn on WiFi, I was redirected to the WiFi menu and attempted to turn it on again. Of course it failed the first time, but I repeated this process of opening Allshare and pressing "Back" when it tried to redirect me to the WiFi menu. Doing this two or three times somehow managed to get my WiFi finally to recognize and now it all works. I would say, that if anyone is to run into this issue, I think it's Allshare related. This is what I did to fix it, hope it helps.
thank you for that. i'll go try it out
None of that works. Does any developers or anyone with some experience have any advice or fixes? Much appreciated.

I'm pretty sure it had something to do with Allshare or XBMC. I think it has something to do with the phone having to scan a network for other devices to obtain indexes. When I was messing with allshare, I disabled the wifi in the middle of the phone attempting to scan my network for my media servers. That's the only thing I did, so it's the only thing that could have caused my issue. When I opened allshare again it asked me to enable wifi, I received the error a couple of more times then after a few times it fixed itself, which led me to believe that it was allshare that caused the issue to begin with. I'm hoping that samsung is aware of this bug.
Same issue, first time I restored a Nandroid backup to get things rolling again. This time I was testing a new DLNA server at home with AllShare, since then Wifi wont stay on. I have sent a message to Samsung support about it. Rebooting doesn't seem to help, not sure how to do a workaround.
Best thing is to go into AllShare, make sure Wifi is on, wait a few seconds and then go to home screen. Usually after a few tries the Wifi setting will stick.
Like I said, all I did was to try and go in and out of Allshare back and forth between the Wifi application and enabling/disabling Wifi. After a few tries, it magically enabled successfully and worked. I wish I had a better fix or better advice, but all I can say is that I just had Wifi disabled, attempted to launch Allshare, Allshare told me to enable Wifi, so it automatically took me to the Wifi settings menu, I enabled it, received the error, went back to allshare, it sent me to settings again, I enabled wifi again and immediately pressed back to get back into Allshare, at which point I just bounced back and forth between the two, hitting back immediately to get back into Allshare, and somehow Wifi worked. This leads me to believe that Allshare didn't finish "something" with wifi, so interrupting Allshare in the middle of a network scan is bad.
already returned one unit to tmobile because of this issue a couple weeks ago had no idea it was related to allshare. makes sense i was using it to try to stream to my xbox the day before
Looks like a pattern to me!
Also, if you are using Juice Defender, you may have a setting that is turning off WiFi.
Fixed for me
So I had the same problem. Not with allshare, never use it. Just randomly stopped working. Anyway, follow the link below, it fixed the problem. It does require root and editing the conf file rather than deleting it. I had a missing } from the end of one of my entries for some reason. I removed all of the saved ssid's and put in the missing } to the end of the t-mobile entry and no more problem!

I'm rooted, deleting that file worked fine for me and it was recreated (the one early in the thread)

First of all wrong forum, either put this in the phiremod thread, or in general or somewhere else besides development, Do not make a thread in Development unless you are developing something.
Second of all, did you load anything new before you went to sleep, did you make any changes?
Hardware rarely just stops working....
Airplane mode. Check that out.

I had this happen to me twice with CM7, the only way I was ever able to fix it was by doing a full wipe and re-flashing the rom. It was not pleasant but it was the only thing that consistently fixed the problem. To make it a little less painful in the future try using the My Backup Root app from the market.

Hey nemith, thanks and thanks for all the great work you've done and are doing!
Yes, I know Airplane mode is broken, perhaps I should have been more elaborate in response to the OP in asking him to "Check that out.", meaning search. I'm guessing he inadvertently touched the setting and spazzed his wifi and if he had spent a sec to search wi-fi problems he would have found his answer and perhaps dug into settings.db and fixed it.
Then again, it might be easier for him to just re-flash.
I've had the exact same problem with CM7 stable 7.0.2.
Although it automagically disappeared when I deleted my remembered networks and all available networks showed up then.
thanks it got fix by its self then it came back after another week when i turned off wifi to save battery then i tried the airplane mode thing and then came back and it worked agian so ill just not ever turn off my wifi and get that my back up root incase i have to re flash CM7
I seem to be having the same issue with my NC, I just recovered into clockworkmod, fixed permissions, wiped the cache, then wiped the dalvik cache, then went into my wifi, "forgot" a hotspot and that solved it. It started scanning again; No reinstalling or rerooting required.
I posted a similar thread in the forums for the T989, but didn't get a good response, so I figured I'd try here.
Basically, my wifi stopped working for some reason a while ago. I got it early in January, and the wifi was working initially, but eventually stopped for some reason. I tried rooting it and upgrading it to ICS, and the wifi began to work sometimes, but it was hard to tell what I could do to trigger it working. I think it had something to do with toggling various power saving settings.
Anyway, I've tried basically everything to get the wifi working. I've tried dialing those test codes, like *#*#526*#*#, and those didn't work. I've tried flashing various custom and stock roms, being rooted and unrooted, flashing kernels, flashing the radio, using Wi-Fi fixing apps, etc, and I haven't been able to fix it.
Right now I'm on AOKP Jelly Bean 4.1.2, and the Wi-Fi works intermittently at best. Last night it was being incredibly cooperative, but for some reason this morning it quit on me again, and won't work. Currently, the switch to turn Wi-Fi on is greyed out, and I can't move it, but the screen says "Turning Wi-Fi on...". I'm seriously at my wits end, and have no idea what to do. Can anyone offer me any help here?
After a recent snafu in trying to remove root from my Nexus 7 tablet and installing the 4.3 update I think there are issues with with it's ability to keep a constant wireless connection, Juice Defender be damned as way before root and even during root I was able to maintain a flawless connection although I think the issue may have arisen during my installation of a cracked google play store app.
This was a couple months ago though.
However I decided rooting wasn't worth it and wanted to update to the new 4.3, this is where the snafu occurs, unrooting wasn't a problem at all, nor was flashing stock recovery, but the process of installing 4.3 was since even performing the update in my settings wasn't working, it would download and my tablet would restart and try to apply the update but soon after it would error out and I had to perform a hard shut down.
After that it would boot like normal and there were no issues, other than the update failing to apply.
So I decided to try and apply the update manually and as it turns out, I was attempting to install the update for the mobile version of the tablet instead of the wi-fi only one that I have so it didn't install correctly and simply erased all data on my tablet except luckily for the devices fastboot mode.
Seeing that I installed the correct 4.3 factory image and this is where the wi-fi issues come into play (I wanted to explain in as much detail as I could that might shed light on my current wi-fi situation).
The tablet booted up seemingly normally, taking a bit longer than it should have to me and upon getting to the glowing X before the main screen it suddenly reset it's self and then booted up correctly; so I finished the set up process after linking my wi-fi up but while going through each app that uses wi-fi I started off with games like Happy Street and The Sims Freeplay which worked normally.
Then I got go my Bank of America app and it's the one app (besides the Play Store on occasion), that didn't work at all, instead it just timed out, there's a screenshot so you can verify for yourselves.
You can clearly see I do have an established connection but this is the only app that fails to work after the update, again besides the Play Store but I've removed root and the crack is no longer installed, not that it would work anyway without root access but it doesn't concern me as much since it'll connect after force closing the app and starting it again.
So that's my issue in detail, is there something that I messed up that's preventing the device from maintaining a connection? Or do I simply need to re-install the factory image to restore connections?
Hmm...I've been having some trouble with WiFi as well.
I was running CM10 and then installed the 4.3 factory image over that. That's where the problem started. Since then I've tried the 4.2 factory image, Ubuntu Touch, and I'm now back on CM10, but the issue remains that my WiFi seems to stop working even though the icon in the notification bar says that it's connected.

Well the weird thing is, is that every other app seems to work but that one where it just times out, I'm going to try just re-installing the update and see if that helps things.
Edit: After backing everything up I decided to re-install the 4.3 update and after downloading the Bank of America app it started up instantly, froze for a moment and allowed me to sign in.
I closed out of the app and tried again to check and after 3 attempts to sign in it worked each time, I think the re-installation did the trick.
