Help-Wifi not working."unable to scan networks"

Hey guys im stuck with some dead wifi, i try and connect through settings after a fresh restart and when scanning i get a popup saying "unable to scan networks. Ive been using different roms since original stock 2.1 and ive never had this specific issue. Does anyone know if there is a way to fix this without having to reload my nandroid backup? Or at worst odin. Which i dont mind doing because i have backups, its just a pain in my arse.
Also i think this started happening after i ran wifi tether the other night for like an hour. My phone reboot a few times because wifi tether adhoc is so bugged but yea, maybe that crashed something. I dunno.... any help is greatly. Appreciated.

Maybe you have a hardware problem/failure.

You can try clearing data cache and Dalvik cache in Clockwork.

Unfortunately clearing dalv and data put me in an odd boot loop. I just did a nandroid backup and that fixed me right now. Not sure what killed my wifi.

Wifi is fixed now but the suggestion of clearing data and dalvik put me in a boot loop.
All is well now. going to just leave everything how it is until Gingerbread

Sounds like there was more data corrupted somewhere and restoring the nandroid brought you back to before that happened.

Call ended issue

Hey guys,
So I googled this and looked this problem up on the thread and didn`t seem to find any answers and thats why I`m opening another one.
So anyways, I was initially running Highonandroid 0.3 and when I saw the new synergyrom, I decided to flash it (I made a backup before this). Flashing the new rom, it couldn`t register my network (Rogers canada) so I decided to revert back to my rom before.
After reverting back, I noticed that lte and texting works but calling and receiving calls no longer work. Every time I tried to call, it would just say call ended and on call logs, I notice it said call cancelled. I would like to try to fix this problem without resorting to reformatting everything because I backed it up to avoid such an issue to begin with.
I`ve checked my config and everything seems to be in place.
Anyone know the solution to fixing this?
Thanks!

That's really weird.. try resetting your APN's to default. Just press menu under APN. If that doesn't do anything, you should try a clean flash.. Wipe System/Data/Cache/Dalvik. I've never heard of this so it's probably a one off problem.

LOL after setting it to default, I lost my rogers APN thing and in fact, the menu changed too . Says System select and CDMA subscription now. So texting and my lte is gone atm.
I have tried wipe system and then restore and wipe everything and restore again and before booting back into the os, I cleared the cache and dalvik as well. This is pretty weird.
I'll restart and see if the APN default thing goes back to normal.
(ok so after rebooting it, i went to the settings and manually pressed by my rogers lte and data and texting works again but call still fails to work :/)

Wiping data or factory resetting in recovery won't wipe your internal SD. You'll only lose app data and have to redownload all your apps.

WiFi not turning on?

Ok so a couple of days ago I installed a 4.0 ready radio on my galaxy s2 and then went on to install Jedi Knight 6 ROM (4.0.4 and radio is UVMC6) and after installation everything was working fine.. I was messing around for a while.. it worked today, I shut my phone off to charge it up real quick, and when I turned it back on my WiFi would not connect. Well not necessarly connect.. it just wont even turn on. When I go into settings and click WiFi, it just sits there saying, Turning WiFi on, and never changes.. I can't seem to imagine what could have happened to it, and I really dont wanna have to reinstall the ROM again because i just spent hours getting this one all set up to my liking...
Anyone got any ideas?
EDIT: BTW, I have tried many things.. Tried airplane mode to disable everything then turn it back on, obviously tried rebooting the phone, i have tried wiping cache in CWM recovery and also tried fix permissions in recovery (another topic said to try those..)
Nothing has worked so far, i'm about to try reflashing my radio, see if that works.. but I really really dont want to have to reflash my whole ROM.. So if anyone has any other ideas please help, i'll edit if the radio works..
EDIT 2: Reflashing the radio did nothing.. it's really wierd, the data, bt, gps.. all of it works fine, it's just the WiFi that's frozen turning on... cant get it to stop turning on and can't get it to actually turn on..
EDIT Final: Ok well, i guess nobody knows what might have been going on.. so I just wound up reflashing my ROM, which obviously fixed it.. i just had to lose all that time spent setting everything up... But oh well.. Kinda sucks nobody even tried to help..

+1 I'm going through the same thing now

I have been having this same issue as well. It started out as stock happening sporadically. One thread suggested rooting and removing my account. Problem still occurring. Tried flashing multiple ROMs and now WiFi hasn't connected at all always stuck at turning on. I have tried clear cache, fix permissions, as well as reinstalling ROM dirty and with factory reset. I'm hoping this isn't hardware failure because I just bought this phone used but it seems to be a reoccurring problem with others as well. Any NEW suggestions not given from quick Google/xda search?

I'd suggest to check your Wireless Access Point (modem or router) wireless settings for security, check and see if it's set to use WPA/WPA2, which is common on some modems/routers, change it to either WPA or WPA2 (preferred) not both, it's a known issue with WiFi networks and having it set to using both, I had the same problem before with my phone connecting to my WiFi.
Also if you use MAC Address Filtering on the modem/router, you should disable/clear that and let phone re-connect before enabling mac filtering again.

The problem I am having is not that it won't connect to a particular network. Wifi will not initialize on the device at all and is stuck in "Turning On..." state. I found more and more posts where people ended up having to send in to Samsung so I spoke with them and even though I purchased the phone used its thankfully still under warranty and they will be replacing it. The did not confirm whether or not it was a true known device issue but were quick to file the exchange for me.

sigh, me too!
Just started having this problem on 4.3.1
great.

In my case, I had to wipe system and data before reinstalling my ROM.
Though the only reason it was happening to me was because Beanstalk 4.4.2 didn't want to get past the splash screen when I tried to install it so I downgraded back to ICS 4.0.4 without wiping. Good luck getting this issue fixed. Also another kernel might fix thingz for you if your current one does not like your device.

I have a similar problem. After a while, WiFi gets disconnected. If I go in settings - wifi, i get the message "unfortunately, settings has stopped" and I can't get WiFi to work again until I reboot the phone. The Wifi works again for a couple of minutes then stops.
I have flashed various different ROM (CM11, PA) but keeps getting the exact same behavior.
I've rebooted in safe mode and I don't get the problem now.

[Q] SlimKat 4.4.4 and WiFi Reconnect issue

First, I've had this issue since Build 6.8. I was hoping a Clean Install using Philz Touch Recovery v6.48.4, which is the latest, and selected Wipe Data and select Clean to install new ROM which Formats /data, /cache, /system. I also wiped Dalvik.
Once completed I did the following:
Clean Install of Slim-d2lte-4.4.4.build.7.0-OFFICIAL-5979
I then installed
Slim_full_gapps.BETA.4.4.4.build.7.x-190
Rebooted and waited for SlimKat to boot-up. WiFi/Data both full scale. Everything Restored just fine and things are running smooth.
Then after running a few errands outside of WiFi Range, I returned home within WiFi range only to find out that WiFi had not reconnected. It tells a WiFi connection is available but will not reconnect to it. So I go into Setting and select WiFi and tried to manually reconnect. It says connecting and then goes back to Saved Connection without connecting. This same thing on other WiFi connections such as McDonald's or other open WiFi Connections.
I then do a re-boot and everything is back to normal. WiFi connects without issue and again things are fine and running smooth.
Every time I leave WiFi range and then return within WiFi range, the problem re-occurs. A Re-Boot and everything back to normal.
One thing I've always noticed when doing a Clean Install as stated above, all of my previously stored WiFi connection are still there. Same on Ringtone/Notification Tones.
With the problem I'm having, could it be something that is not being wiped/cleared out during the Clean Install process. Or wondering if it could be somehow that the WiFi Radio has gotten corrupted.
I have also tried different Kernels but again the result is the same.
Hope this is not too much of a noob question and I have searched about everything I can think of. Wondering if anyone has had this problem or have any ideas of what could cause the problem.
I really hope I can get this figured out. Thanks

If you don't have to manually reconnect and enter your password, then its not being wiped. (Or you are restoring it from a backup.) Have you tested it after the clean flash, but before restoring anything? What are you restoring and how?
It sounds like a Rom issue otherwise and you should probably ask in the rom thread.

First I don't know what I've missed wiping. When I say restoring, I'm referring to letting Google re-downloading everything from the Play Store.
I know the WiFi radio are in a different location but like you, when I do a Clean Install by formatting /data /cache /system and wiping dalvik, I wasn't expecting all the stored WiFi connections to still be there, but they are.

Its possible its being restored by Google's backup, but I don't use it myself so I'm not certain about that. Its also possible the rom may save the config file elsewhere. Again though, I don't use cm/aosp based roms so I'm not too familiar with any of their specifics.
Next time you try a clean flash, do not sign into google during setup. Instead go straight to testing wifi to see if it still remembers the connections. Do you have it set to auto connect to any open networks? If so you might want to turn that off.
Have you searched or asked in the roms thread yet? It might be a known issue or something a few others have encountered and know how to fix.

Ya I don't sign into Google at the initial start up after the flash because my WiFi is no able to connect. I will double check the auto connect feature. But I having this issue with other 4.4.4 ROMs also because I tired however on those ones I am amvle to toggle WiFi on but in advanced it has the region set to Europe and when I switch it to Canada it doesn't want to save the change

[Q] Wifi Connection Issue

Welp here I am again. My note 3 is weird for some reason. Before I decided to flash a rom, I ran a stock rooted note 3. However, one day my school's wifi connection went haywire and it went down. After a day we discovered that the school just changed the password on the wifi. I figured the wifi password out and it didnt work. All it said was saved and secured. I am 100% sure I put in the right password because for every other student it works right now. And I know it's not the rom because this happened right before I flashed dompop. I tried using the wifi at home and at my tutoring place and they both worked. So is this a problem on their end? I also tried rebooting and forgetting the network. Also I CAN NOT REBOOT THE ROUTER because it's the schools and i might get arrested for climbing onto a desk to take the router off the ceiling LOL. Also I cant access the gateway to see if the bands that aren't working with my phone. I'm really frustrated because my peers are using the wifi and I cant even get on. Help Please

Since you did what I would suggest (forget router, and re-add) the next thing would be what you can't do. Unplug the router, and plug it back in. Maybe something in cache is stopping it. Try forgetting it again, and wipe cache, and then try it again.

Yes. I would wipe through recovery. Cleaning app cache probably wouldn't hurt either. You can either do it manually through the apps setting, or use an app itself like: https://play.google.com/store/apps/details?id=com.jrummy.cache.cleaner

Dalvik cache or regular

Sorry. I'm pretty much out of ideas. The only thing left is flash the ROM over again. Not from scratch (this time), but just dirty flash it right over the current ROM. If that doesn't work, and without being able to reset the router, the only thing left is to format the phone, and start again from scratch, and hope that works.
