Hello! So this issue started about 2 weeks ago for me. Whenever I turn my wifi off, the phone will turn the wifi back on for 0.5-1.0 seconds then it will turn it back off. This happens nonstop. The issue persisted even when the phone was in safe mode and still continues even after 3 full factory data resets and wiping the cache partition 3 times as well. I did this through recovery mode. Nothing changed. When this is happening, it seems to drain my battery significantly. The only fix I have found for it has been to leave my wifi on all the time, even when I am not connected to or near a wifi hotspot. The issue also does not happen when the phone is in airplane mode. Also, I did not receive any software updates around the time this issue started happening. I have tried Googling and contacting Samsung and could not come up with a fix.
Is anyone else having or had this issue? If so, did you find any fix? Thanks!
If this thread needs to be moved to the help/troubleshooting section, please tell me how to do that, or do that yourself if you would like mods. This is my first time starting a thread so I am sorry if I put it in the wrong place.
Possible Fix
My Note 7 and S7 Edge were doing the same. I fixed it by disabling "Wifi scanning even while Wifi is turned off" in location settings.

I'm really hoping this isn't a hardware issue as I would dread having to go get my EVO replaced and restore everything to how i have it, but I'm having an odd problem.
WiFi randomly stops working after a reboot sometimes. I turn it on, it scans for about 4-5 seconds, says "Unable to scan for networks" and then WiFi turns off. The only way I can solve it is by flashing back to flipz' stock rooted ROM. Reboots won't solve it, battery pulls won't solve it, turning on and off different networks won't solve it, nothing. Has anybody else had this issue or know how to fix it? Thanks guys.
did you update your firmware/software? the sprint rep had be update EVERYTHING before activating my phone.
yep. problem still occurs
After 2 days of testing I've narrowed it down to being either a setting or a corrupted system file from a backup. Hopefully it won't show up anymore.
My phone has had absolutely no problem connecting to Wi-Fi for the longest time. About a month ago, it started refusing to connect to Wi-Fi properly. If I go to the wireless settings, as soon as Wi-Fi turns on, it turns itself off immediately, and it keeps doing this over and over. I've tried different kernels (including stock), different ROMs, which sometimes fix it for a little while but it always goes back to this. Is anyone else experiencing this problem, or know how to fix it?
i have a samsung galaxy note 2. i got a popup msg from att alerting me that i was exceeding my plans data limit. shortly thereafter, i noticed wifi wasnt on. i tried to toggle it on, but the button was greyed out and would not allow me to slide it to the on position. it seems to be permanently off. i have powered off the phone, taken out the battery and sim and sd card, powered it back on, still not able to select the on switch on wifi. i reset my router, still nothing. i downloaded wifi fixer, still nothing. i have been reading up on this and it seems no one knows what gives. my phone is not rooted. i have turned off wifi power saver. i have not performed a hard reset as most posts i have read said that didnt work. i'm at a loss.
bluetooth is working

I had something similar in that I would turn on wifi and it would not turn on. Tried everything you did, even the hard reset w/ no love.In my case once I turned off Bluetooth and tried to turn it back on it began exhibiting the same behavior. I was able to "fix it" by booting up in safe mode, turning on the wifi (and BT in my case), and then rebooting. It has been working since then without issues.
Hi,
I've had my Galaxy Nexus for over 2 years now, and never had any major problems with it. However, over the past month I've been having a problem where my network connection stops working. I can't call, text or go online. I also can't receive calls or texts. When this happens, the connectivity icon still has 4 bars (or 3 or whatever).
In the past if I had network problems, I would put it in airplane mode and then turn it off, and this would reset the connection and fix it. Now, when I try to put it in airplane mode, nothing happens. The connectivity icon disappears, but the airplane icon does not appear. Then there's nothing I can do except reboot the phone. I can't even turn airplane mode off because the option is greyed out.
At first I thought I could fix the problem by resetting the phone to factory settings. That didn't work. So 2 weeks ago I installed Cyanogenmod 11, and the problem persists.
Yesterday I installed an app called "Restart Connection", but it hasn't happened since yesterday so I'm not sure if this will work or not. The problem is not regular. It can happen twice in a day, or it can not happen for 3-4 days in a row.
I'm not sure where to go from here. I've tried Googling but can't really find anything quite like this. It wouldn't be so bad if I knew when it happened, but if I don't happen to be using my phone, it can happen and then no one can call or text me until I realize that the problem is happening, so I can be without a connection for hours at a time before noticing.
Anyone have any idea what could be causing this and if there is a fix?
Thanks!
This happens at least 4 times a day, it's annoying, I have to switch to airplane mode and back again to get it to reconnect.
I also get this sometimes . When I look at the wifi access point on the phone, it says that its down to poor internet quality .It usually corrects itself in approx 10 minutes with no action taken on my part.
Do you have WiFi set to turn off when the phone is asleep? If so, try setting it so WiFi stays on during sleep and see if that helps.
I got the same problem since I rooted
Been trying to figure out if its a VENDOR Firmware problem or what. I do know that every developer says its a bug with the s9 when rooting. I've personally watch the live log on TWRP when flashing and seen where it mounts the VENDOR Firmware and then unmounted at the end. So it could possibly be a problem between TWRP and the s9 ROMs idk know exactly yet but I'm looking for a solution also. Keep your head and keep searching also then reply back here when you find something. I'll do the same. Good luck.
Its still happening sometimes its fine a for a couple of days then it starts acting up, my girlfriends S9 does the same so maybe it's something to do with Virgin Routers.
