I have found WiFi to be very hit or miss. Sometimes it will work all day but other times I will have connection issues like "connected, no internet" or "obtaining IP address." This is very annoying and if I can't fix it I just may have to return the phone.
Are you running a custom kernel? Have you tried turning airplane mode on for a little bit and then back off?
I am running completely stock with the latest update from Google. Putting the phone on airplane mode doesn't fix the issue, neither does turning WiFi off and on. The only way to solve the issue is to restart the phone.

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?
With ICS when I first turn on my tablet, the WiFi often does not connect, even when the signal is strong. WiFi is on, but it does not connect until I turn WiFi off and then back on or manually select my home or office network. Once in a while this happens I turn the tablet back on after it has gone to sleep.
I tried restoring to factory defaults and it fixed the problem for a few weeks. But it has come back again. Has anyone seen this problem and found a solution?
I am using the OTA version of ICS.
I have also had this problem on occasion, but it seems to be happening less and less which is strange. I haven't gone to the effort of resetting my tablet.
There are many little quirks in ICS that I think will need ironing out with an update. Whether Acer think it worth their while is another matter.
I am on stock ICS - Rooted.
I know its not a fix, but normally I just toggle airplane mode from the system bar. Seems to be the fastest way to get it going. It happens on about 25% of cold boots to me.
Been happening to me every reboot since ics. Another incomplete release.
My phone is rooted, im on stock 5.0.1 no custom recovery or anything like that. I haven't changed or done anything to the phone recently either.
If I hold the power button down and look at the airplane mode option it will flicker on and off and as I lose service. Every now and then I'll get service for 5-10 seconds but most of the time my phone signal and data connection are off. Wifi and bluetooth work.
Any suggestions?
Unrooted the phone and went over to Sprint. They did a factory reset but the issue still persists. If anyone know how to fix this or even has suggestions please let me know. Its an otherwise perfectly working phone.
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.
