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!!!

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.
Hi, is anyone has the same problem? When I'm connected at home to my Tenda router (WIFI b/g/n) after cca 30 min. my phone WIFI stops sending and recieving data, Skype is offline, etc... but WIFI in phone is stil switched on. After I switch WIFI off and back on (on my Samsung, not on my router), everything works good for a while and after cca 30 min. is situation the same. Is there in Samsung any WIFI sleep mode or something like that? Or some settings, which is not visible? Any other suggestions? Sorry for my poor English. Thanx in advance.
I'm having the same problem. But I did a factory reset and it works fine afterward.
And just few hours ago, I encountered this problem again. What did to get this error was, I pressed "on samsungapps" and it failed to update and thus results wifi connection stopping. What about you? Also my Kies air is not working.
are you guys sure you have wifi sleep policy set correctly? just to be sure, settings, wireless, wifi, menu button, advanced, wifi sleep policy to NEVER.
Yes. And also even if i manually disconnect and reconnect the wifi back. The data still doesn't come in. It is stated there as connected but no data at all.
Somehow Wifi keeps searching every few seconds, even thought it's connected.
This is bound to cost in battery life too.
I have reseted router to default settings, disabled n mode, disabled security (only mac filtering is on), disabled all unnecessary features and PROBLEM IS SOLVED !!! Thanx God Tomorrow I will experiment with router settings to know, what was causing this error ;-)
Well at least u're connected, I'm facing the same problem as the thread starter. No data flow at all. Browser showing me offline msg. I had the same problem on the 1st day with the phone after I woke up. previously playing with most of the default aps. So i'm not sure what went wrong, did a factory reset and it works fine.
Until, few hours ago, I tried my kies air which didn't work. Browser couldnt load the address given. And I thought i had an outdated kies air, so i went to click on samsungapps, which failed to update me. At that point the wifi is still working, i leave my phone for about 30 mins, and when i came back. The same problem which happened on the 1st day came back. I was hoping to find an answer here so I didnt do the factory reset it. On another note, the phone wifi works after restart, but wouldn't last.
Edit: The wifi works after i resetted my modem to default. oh well. at least that solved it.

Hi,
Did you find out what setting was causing the connection issue? I also have this problem with my Tenda router. I thought it might be the wireless N, but disabling that doesn't fix it. I have a wireless distribution system set up with other tenda routers so didn't want to disable all the settings to troubleshoot if i can help it!
Thanks

I have the same problem, my router is N and the conection between SGS2 and my router is bad. Any idea?
Same problem here, I'm running WZR-AGL300NH in access point connected to my Ubuntu Server. Everything else works in the house just fine but SG2 stops transmitting data after a while.
I recently upgraded to KF1 firmware (and unknowingly wiped out whole phone, being on the bleeding edge and that didn't seem to help.
I would very much appreciate all tips because this problem is very annoying!
Additional Info:
- Buffalo is running latest firmware
- Authentication WPA2-PSK
- Encryption AES

Same symptoms here. Cisco DDR2200. WPA2 PSK. Haven't tried fiddling with the router yet.
This seems to be a common problem. Anyone knows of a definitive fix?
Bump...I have the same problem and the issue persists even after i reset the phone
Sent from my GT-I9100 using XDA App
Glad I found this, thought it was the ROM I had flashed to the phone (which is VillainROM)
I keep losing connection from my phone via wifi like everyone else in this thread
edit: I've just assigned my phone an IP address via my routers settings and I can connect to the net again
Also when it wasn't working, I couldn't ping the phone. When I assigned the IP just now I still couldn't ping it.
When I did a tracert to it, I could get to it when the IP was assigned and when it wasn't.
I have no removed the assigned IP for the phone from the router. Wifi connection is still working after disconnecting/reconnecting wifi on the phone.
I can also now ping the phone, where as before it was getting timeouts.
Also when it wasn't working the first time when I did a tracert it was showing up as HPsomething (didn't make note of the numbers)
this time when it is working it's just showing up as the IP address when doing a tracert.
Another update:
Just checked my printer, it has an IP address manually set on it, which at one stage when the phone wasn't working for internet it had the same IP as the printer, hence when tracert'ing it I was going to the printer instead of the phone and getting the HP etc back.
When it wasn't working at that time and looking at my routers DHCP list, it had the MAC Address of the phone against the IP that the printer has....
So I've got some issues with how my own network is setup ^_^ which looks like is causing me grief.
So the issue is with DHCP? Setting a static IP fixes it? I'll have to try, but I doubt this is a problem with the network, as all my other devices use DHCP without this problem.
I have the exact same problem!!
It's really annoying.
i was having problems with wifi too.. it keeps scanning and checking, etc, signal dropping for no reason..
fixed mine..well for me it worked
backup ur phone ( i dont take responsibility if ur phone catches fire or dies or chases u around )
u need to be rooted
download FXR WiFi fix and rescue from market
and just run the app.
now my wifi signal stays constant speed and i get good speeds
alternatively try
WiFi Fixer
both of them will cause high battery usage..i think since it keeps the signal at maximum.. so only enable wireless when i need it or use juice defender or green power.
greenpower seems great. using this at the moment
Hi i went from stock ics on my ray to cm9 by followingnexact step by step guide provided by cm9. Used their kernel as well. Have never modded my phone before. Having a small problem with wifi though. After my phone has been asleep for a while, if i wake it up the wifi icon in status bar is no longer blue its a dark grey and i can no longer browse anything or use the internet. Ive tried rebooting. I did the whole wipe cache etc when installing cm9. In wifi settings in advanced ive also left the setting to "leave wifi on when sleep" checked. If i turn off and on the wifi connection the phone ofcourse is able to reconnect again the icon is blue and i can connect. It not jsut a one off thing its been happening since i isntalled the rom.
If i wakek from sleep a few minutes later i have no issue with wifi. Its only when its been sleep for a while do i have this issue.
Any solutions?
I have the exact same problem but for me it's even bigger, whenever i turn on wifi on my modem, i can connect to internet on my phone, but after awhile i lose my connection completely, on my phone and on my pc also, the only way to get it back is to reset my router and wait for like 5-10minutes...

If its also an issue with your. Pc then your issue might be also the router.
My other devices actually work fine in my case its oky this phone that has issues. Macbook iphone ipad nexus s no problems with those.
Same issue here. I can see available networks but unable to connect. There should be no problem with the wifi router as all my other devices work well and I have tried another router. Now I have to flash back to stock firmware.

Your issue seems more severe than mine. Mine actually connects and works, just that when it wakes from long sleep it wont work until i turn off and on wifi.
I get this problem too, but my problem even worse than yours. My wifi lose it's connection after a while, but the icon on status bar shows it's connected, running ping test, browse, even play store can't be accessed. I pinged the router and got unreachable.
And yeah, this problem occurs when I'm using all ICS based rom..
Anybody has any idea if this is a known problem, or if its just us few having thisissue?

I have same problem. I have SE xperia mini with CM9. WiFi worked fine until yesterday. Now phone can't connect to AP (full signal - try connect -> signal drops down), but sharing 3G internet over WiFi works fine. I cleared dalvik cache, but that didn't help.
Anyone else having issues with Wifi Calling since updating to 5.1.1? It randomly goes red on me and shows an error of er081 or er082 and sometimes the Wifi Calling icon just vanishes though in settings its still turned on. I have tried a reinstall of Lollipop, tried a reset etc etc and the only way to get it back on is by turning Wifi Calling off and back on but 10 - 15 mins later it goes red again.
Happened to me so i booted twrp, cleared cache and dalvik the rebooted. Went to system, apps and cleared cache,data on the wifi call settings/apps and rebooted again. I also always kept smart network switch off but it works well now.

I had 081 errors also after flashing to 5.1.1 rom, there are several threads on the t-mobile forums discussing enabling PPTP and IPSec pass-through and in some cases PPPoE relay In your Router settings. In my case enabling pptp and ipsec pass-through soved the 081 errors. Not sure why it wasn't a problem before going to 5.1.1...
g900T wifi calling & net10
wifi calling crashes when i try to start it since OTA 5.1.1. I have net10 service and you required by net10 to have wifi calling to make calls....data and messaging work fine
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.
