Wifi wont stay on

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 can't post links so change the below hxxp to http

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

It's worked . Thank you so much.

none of the "fixes" posted work. im bone stock, running eclair. same wifi errors as the op. The phone is to be used as a wifi only device, since the sim is not active. is there a real fix for this?

This is helpful information. thanks.

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.

XOOM won't connect to google...

My wifi Xoom, using EOS 155, hasnt been able to connect to google's servers in several days. everything else works fine.... browsing, the amazon app store app, irc, etc. But the wifi icon won't turn blue, and when I try to goto the Andriod market it says it can't connect. gmail seems fine... just sent an email to another account and got the reply....
If i go into settings and look under accounts, everything that I have setup to sync says its doing it.... I just can't access the market and the wifi icon is grey.
This happens no matter where I'm at... my house, my friends and family, work, etc. So I know it can't be the network I'm connect to. I haven't made any changes to any settings in a while.... so unless something changed without me doing it....
I've power cycled it numerous times... both rebooting and turning it off completely and then back on again.
Anyone have any ideas what might be the problem???
Thanks

Strange problem... been using EOS for months now and have not had a similar connection issue. Only problem I had connecting to Google site and Application store occurred when I move to Google 2-way authentication and had to setup the security properly.
Did you have this same problem using an earlier version of EOS? When upgrading to EOS 155 did you do a wipe or clean your dalvik and cache? I would try a full system wipe and reflash the ROM. Sometimes it is easier to redo it from scratch then track down a particular issue.

I've never had any issues with any version of EOS, and I've been using them since night 1. And I had 155 installed since it was released... and this issue just happened a week or two ago. So nothing should have changed on my xoom.... unless it was done by some application or something. (And I'm the only user of the device)
I've tried stopping and clearing the cache on the google play app.... which I found the suggestion on another site... but that didn't do anything.
I had this happen before, but it normally just required a rebooting of the tablet, and it would then connect again.
I wish there was something like on windows with the event viewer.... cause I have no idea what the problem is. The error message when I try to connect to the storeis RH-01.
I'm going to install EOS4... but I wanted to wait a day or three until they have a chance to find/correct any early bugs.
I've also been getting error messages about google+... which I never had before. I'll just be doing anything.... browsing, using tweetcaster, playing music, etc and a error msg about google+ pops up.

Could not figure out what the issue was.... I just installed EOS nightly 160.. and everything is back to normal. I don't know if it was a Xoom issue or EOS issue... esp. considering everything was working fine on the nightly I was on for weeks... then all the sudden it stopped.
Reinstalling all my apps...

Simple solution: reflash gapps package.
Lol it's really that simple, I had the same issues as well, but on CM roms.

I've had a similar issue.. but resolved it with simply removing/deleting the remembered networks and re connecting them. This could be an artifact of my network setup with both the router and a wireless extender being visible from my location.. and once in a while it seems to confuse the connected systems.
Of course if I learned to leave my working systems alone.. they might not 'break' so often. but it is just too much fun to play:silly:

Oh well... I should have just tried reflashing everything... but I figured I would move on to 4.2 soon anyway... which I like (4.2) but it's a bit laggy on my xoom compared to 155.

You have to make sure you flash the correct gapps version with the ROMs. 4.2 nightlies require the packages named as follows: gapps-jb-201301##-EOS-XOOM-ONLY.zip be flashed together at the same time. EOS ROM 155 gets flashed with gapps-jb-20120802-eos-signed.zip.

Unable to turn WIFI On.

Hi there, I had my phone for about 5 or 6 months where it was fine till recently.
The problem was that I am unable to turn the wifi on. in the main settings the slider is greyed out and a text is on screen saying turning on WIFI but it does not. it does not even show the list of networks. it quick settings it shows as searching but nothing is listed.
in the about phone settings it shows the mac address to be 02:00:00:00:00:00.
This occurred a few days ago but no new software was installed the most recent being a week before to the April security update.
I have tried multiple things such as turning on the airplane mode then off, switching phone on or off, safe mode, factory reset, wiping the cache, taking the sim out.
There has been instances where I am able to connect to a wifi network but it does not last long (few mins) except when taking the sim out which lasted about half a day. (tried again but did not work)
My phone is not rooted and has the stock rom.
There has been some research on this matter where people have done something with the presist(I think that is what it is call) folder but there was no result on it so I have not tried it due to wanted to keep the phone unrooted due to warranty concerns.
I would love some solutions in figuring out this problem.
Thank you for your time.

Damn. I had the same thing with my n5. WiFi never showed up to the party. That's why I got the 6p... And the g4.... And the

This problem is exactly what happened to me also, since two days ago. I was searching for a solution and found this thread. Can anyone here who had this problem share how they fixed the issue? is it really a hardware problem?
Thanks!

No WiFi connection

I got 2 LG G2 d800 and both started not connecting to wifi, it gets stuck on "turning on wifi", both happened on the same day so I don't think its a hardware problem probably an update of Google services, anyone has the same problem and maybe a solution?

I am experiencing the same problem since yesterday. It just says Turning Wi-Fi on... and it never turns on. It happened when I had my phone charging and noticed a facebook messenger update. The wifi has turned on and worked for a while (especially after some reboots) but then it got back to doing the same thing again. I have reset my phone but it doesn't let me do a hard reset using the power and volume down keys.
Any ideas on how to solve this?

sorry to say, but its broken (99%). i had the same problem. but my luck it was i guarantee time (short before end)

I have made it work for a few hours, somehow. I finally managed to figure out how to factory reset it. I did it a few times until the wifi was working completely.
I started downloading apps and it worked perfectly. Then I decided to try a reboot and the wifi when out again. The difference is that now I have a MAC address and before I didn't. It's still stuck but there's some progress, I guess.
I thought about rooting my phone, but I'm scared of ending up with a brink since I have never done it before.

Me too with my g2:
About 3 weeks that my wifi, hot spot & the stock radio app aren't working like they used to for 4 years!
Did factory reset but it didnt helped
