Hi.
I have two s3 phones. I tried to create a backup using one S3 and restore it on another one (too have same apps on both). Everything is fine, except WIFI connection fails on second phone.
I tried to clear dalvik-cache, but didn't work.
WIFI connection and WIFI-Direct don't work. WIFI sees the router, but cannot connect to it. It shows zero signal strength.
I did the factory reset on second phone and wifi worked.
It seems that some settings/data should be cleared to make wifi work again.
Any suggestion?

Apologies if this has been resolved eslwhere, but I did a thorough search and I could not find the solution in similar questions asked for the exact problem I am having.
I have an HTC HD2, basic Rom 1.66.405.2 (76641)with Max Manilla, Radio version 2.06.51.07.
I have previously used Opera 9 and Opera 10 to surf the internet along with Skyfire with no problems when using the 3G connection or when connected to my home or work WiFi, until a few weeks ago. When connected through WiFi, having changed nothing on the network routers or my phone, I just cannot get to pages. The same is with the facebook app and any updates via weather or stocks/shares.
It seems that as soon as WiFi is connected there is no data connection.
I have checked data connection and it is OK, I have also tried the slider the best as suggested on another forum, even re-installing Opera 10, to no avail.
I am considering switching to Energy Max Sense at the moment but hesitating as I can't bear going through another hard reset and re-installing everything, but this issue might just force me down that route.
Any thoughts before being forced down this route?
Been through lots of different settings and basically it appears that once wifi is connected I lose all data connecions, nothing then connects.....Please help?
Did you ever get this fixed, because I am now having the same problem.
I used to get internet data connection via wifi by first turning off data connection in comm manager, then turning on wifi. I must have screwed something up, because now I cannot get any data traffic via wifi. I can't even get data from my cell network whilst wifi is on, I have to turn it off to get my GPRS connection back. Bit frustrating, been through connection setup and delete/setup network many times to no avail. What have I done... harrumph!

Why Disconnect data connection before activating WiFi?
I leave it on, still it will get data through WiFi is available.
If you disconnect data connection, you will not get data through data connection. (while you have WiFi activated, as you switch it off)
Have you tried using both at same time? Perhaps disconnecting data connection does a "trick" so you can not get data through WiFi too and you are now experiencing expected behaviour. (And that it did before was the wrong situation.)
i tried lots of stuff, soft resetting each time, I then did a full sync and backup to my home PC (work PC has firewall and stopps internet connection).
After that I did a cache cleaner and emptied a lot of trash, it did appear to be running slow. Did another soft reset and voila in the morning it was all working.
I played around with settings, double checked everything and to the best of my knowledge nothing had changed to cause this fault, so no idea if it was a problem with synching between the two PC's, work and home, or whether the cache cleaner did the bizness. Never had the problem repeat again since.
Have you tried getting settings from your provider again maybe something got wiped by accident.

It did indeed, thanks.
I've tried searching and haven't found anyone with the same issue as I.
Jellybean broke my wifi, I had no connection issues before whatsoever.
Now, it still shows it's connected to the network with full strength but when I go to use the internet or any apps, it says there is no network connection, webpage unavailable, no autosync, etc. Things are fine when I go back to 3G and nothing has changed on my phone but the JB update. I've turned Sprint Optimizer off and on, deleted and manually readded all the wifi networks, and am not sure what else to do besides hard reset. Any ideas? Also, I am not rooted.

have you done a complete network reboot (cable modem and wifi router) when having the crappy sprint connection optimizer off?
if this helps you feel free to hit the thanks button
Thanks for the help! I found the answer in another thread... Seems JB automatically turns on "DLNA auto-ip" for some people. The fix that worked for me was Settings>Wifi>Menu>Advanced and uncheck "DLNA auto-ip" at the bottom.
Hi,
I've tried a factory reset but the problem is still there. The tablet picks up wifi signal, connects, but then gives an 'out of range' message. I've tried more than one wifi so not the modem. I have another identical tablet that doesn't have this problem. Any ideas?
guys, i decided to use custom rom on my old i9100 that i kept in perfect state until today, i've been using it for days normally, but since i missed the marshmallow cache cleaning system, i decided to clean it, kept using it and went to sleep, lefting my wifi connected and when i woke it was off, the wifi was not activating and i discovered that for it to work, needed to activate and deactivate 2 times through the notifications panel.
my i9100 was getting very hot and turning off the wifi every time i put it on stand by.
for curiosity, just remembered that i had cleared the cache and tried to clean again to see if it resolve the problem, because i was tired of reboot or clearing cache / dalvik cache through twrp
and now it just stopped working, even switching from custom rom or reflashing, the wifi does not come back
i realized that it didn't detect my wifi mac address (02:00:00.....) and i found on xda that for mac address to work it needed to change the wifi region, this worked, but when it activated it was just searching and not founding wifi networks, nor my neighbor's wifi
and swapping the wifi region and rebooting the previous region not work anymore
i remember using a code in the phone application and my dbm was -1 but detecting mac address, connected n working sending ping to google (this is possible??? it was not connected, but was with SIM card, not connected too but, so idk....) (a option in the same code).
at the moment, wifi doesn't work or activate anymore, only shows off and a loading line, mac address bugged again, using cyanogenmod 13 nightly, last release with security updates by linusdan n the pit is 6gb
anyone can help me?
sorry for my english!!!
I woke up this morning and noticed my wifi will not stay connected, I tried resetting my home network, also choose to forget saved networks, reset all connections, and even did a factory reset. Still wifi will not stay connected. Also tried on different network. I know Pixel 6 had a problem last year but I never experienced this until today. Any Help would be appreciated
Also wanted to say I am running stock firmware for T-Mobile. I did do a security update to see if that would fix wifi but it did not. Have not installed any new apps either.
Figured it out, It was the router after all. I have 1 router and 2 access points., named differently. I left and tried it on open wifi at coffee shop and everything worked. I went back home factory reset my router and put in new ssid and password. Now everything works . I never would have thought it would be router, because laptop and other devices had no problem with connecting.
