WiFi Problems with new Official ROM (I9205XXUCNA2) - Samsung Galaxy Mega

Anyone else noticed Wifi problems with the new ROM?
It was OK for a while then noticed the next day or so it wasn't connected. I tried manually selecting the SSID but it would not connect. I tried forgetting the SSID and re-entering the password but it wouldn't connect. A reboot finally cured the problem and it was fine for another day. I haven't worked out the patern yet I'm guessing once I leave the WiFi signal area it never regains connection?

With the latest update my wifi won't even switch on.
People suggested that I should flash stock firmware, which I haven't tried yet.
I will let you know if it solved my problem once I do flash the stock firmware.

I have the wifi problem today when i update my mega, just do a factory reset and then update your mega again.

[Q] WIFI connection stops transfering data

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

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

Mozart not finding my (non-hidden) Wi-Fi network

My Mozart for some reason can no longer find my home wi-fi network. It was working just fine 10 minutes ago and now, all of a sudden I unlock it and theres no Wi-Fi connection. Checked in Settings but the network doesnt appear in the list anymore.
The network is fine as im using it on my laptop now to type this and on my iPad. I tried switching Wi-Fi on an off several times and also rebooted the device many times too. I also tried adding the network like it was hidden, but no avail...
Any ideas?
UPDATE (PROBLEM SOLVED)
Okay i got the problem fixed, it wasnt a Windows Phone problem, my router suddenly decided to change the channel it was broadcasting on, it was 6 before, bumped it to 11 and now the phone is able to connect again XD
Are you running Mango?
I had problems connecting to my Wi-Fi pre-Mango when the SSID was hidden. Mango, however seems to connect fine in this scenario.
Apologies... I just re-read your question. I seem to have mis-read the NON HIDDEN network.

Yeah im on official Mango, forced it through Zune... And im certain my network isnt hidden...
If you go to Settings -> Wi-Fi -> Advanced is the network shown as a 'Known network'? If so, remove it restart your phone and try again.

It was listed and yeah, i tried that too, didnt work.
I think i'll hard reset the phone to the original pre-NoDo ROM and see if i have the same problem, if I do then it might be a hardware issue? Good thing I still have my warranty...
[UPDATE]
I just reset the phone, lost all my data for nothing -.-
[UPDATE 2]
Restored the phone to 7008, same problem... I'll reset the modem in a few hours. I hope that's the problem because the phone has no problem finding and connecting to networks further away from me...
Have you tried enabling the SSID again in the router setup then connect on your handset and finally hiding it again through the router?

[Q] Unable to connect to home wifi?

It was fine until last night...
I woke up this morning to find that my atrix had lost connection with home wifi, provided by ATT.
I tried to go back on, but it failed, as if I had got the password wrong (phone says its gaining IP address, turns wifi on and off, does the same thing again)
I tried rebooting the phone, retyping the password, which were an useless attempt.
Wifi itself seems like its, fine, since my mother's phone(Captivate) is going fine with it.
I can also connect to other wifi networks,
so I cant exactly see where the problem is.
My atrix is running on ATT, 4.5.91, rooted.
Thanks for your help beforehand!

Did you try telling it to forget the connection, then set it up again?
Have you tried rebooting your modem and router?
Many connection issues are solved by a simple reboot of all hardware involved.

Problem with cm9 and wifi

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.

Question Wifi will not stay connected,

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.
