[Q] -Device- WiFi problems after changing roms - Galaxy S II Q&A, Help & Troubleshooting

Hello,
Not long ago i decided to wipe everything from my device and install new rom and kernel just to fresh it up a bit, i want to highlight this: Before i did it, everything was Alright, at least everything related to internet and WiFi.
Anyway, Since i did it I'm experiencing problems with my WiFi connection (at least when I'm connected to my home WiFi router)
Everything Seems to be OK, i have the WiFi icon on the status bar, with at least 1 or 2 lines of WiFi reception (Same like i had Before i changed ROM and everything was alright)
The problem is that some of the time the WiFi is alright, i Can surf the web and use internet apps like Facebook and YouTube, but Most of the time.... Well i just can't... I do have the WiFi icon but the internet doesn't respond...
Another thing, I'm using laptop and connected to the same WiFi network my phone is connected to and everything is just fine... so the problem is with my Galaxy S2 Device and not my WiFi network..
I found a way to solve it and about 60% of the times i disable and enable WiFi my internet works again for some minutes...
Does anyone got a clue what my problem could be?
Thanks!

Try a different modem ..
Try a different rom .
Put your old rom back on .
jje

i Have tried several other modems and nothing changes,
About the ROM i really want to stick with my new ROM and i haven't heard of anyone using it experiencing same problems...

[Q] X10i Not connecting to Internet after 2.3.3 update

Hello everyone!
Just like everyone else I have been waiting infront of the screen for 3 days now to get this god forsaken update and when I finally get it everything works fine exceopt for the WiFi.
on 2.1 I used to get an Internet connection when on my WiFI, Now im connected to the router with full connection strength but I have absolutely NO internet connection, only an evil triangle telling me that I have limited network access.
This has happened to 3 of my phones (All of which are Identical)
And the only even closest similar issue here on XDA has been with the HTCD which dropped the WiFi connection if the signal was too weak, but mine is at full strength.
In short: My phone can do Everything but going on the internet...
What I have tried:
Putting the phone in DMZ
Disabling Firewall in the router
manually enter Static IP settings
anyone else experiencing the same issues and/or know how to silve it?
bump
[BUMP] just bumping this thread because without WiFi my use of the phone is limited to say the least...
Hi i get this too but ojly since the update, i have it working now but its still a problem it sorts itself out if i leave it on for a bit?

I have the another problem around since 2.3.3.
Wifi works fine,
But when not near a Wifi spot cannot access internet /send mms recieve mms , or download internet&mms settings. And this is the only similar problem i found <.<
But on your problem ofcourse might seem silly but im guessing your already tried rebooting/resetting the router? ^.
I beleive you have to be coolnnected to wifi to get settings for internet and mms.
And yes i have tried rebooting the modem but it didnt work so i just connect to the btopenzone signal my modem also gives off

[Q] WiFi on, connected, full strength and not sending anything.

So I have my Fascinate running CM7 with the Glitch Kernel, no OC, just for the stock UV, the problem I have is that I can connect to WiFi, everything seems fine and then a few minutes later everything stops loading, as if there was no connection. turning off WiFi and turning it back on helps about 80% of the time but still an issue, the reason this is so big is that at my house we have no reception at all, Verizon sent us a Network Extender but it simply does not work on any phone and I know for a fact that my Network is fine. (We have twin N600s one routing one access point) Additionally the issue is at the local college as well. Any help? Is there an issue with CM7 or the Glitch kernel?
I am having the exact same problem. For example, market will stick at "Loading..." while on wifi but when I turn wifi off, my 3g connection will load market fine. It's so weird because I have full wifi signal and it is definitely not my router. It didn't start until I flashed the glitch kernel. Has to be something there. Maybe there is a workaround?
Im running glitch v13 and wifi works great. sometimes after a reboot ill have to toggle it off/on...

I had that Market problem and it disappeared when I got a new router. A full reset/wipe of router may have fixed it also. Happened on 2 CM7 phones (Droid2 and Fascinate), but not a stock 2.3 Droid2.
On my CM7 Fascinate, I usually also have to toggle wifi after reboot.

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.

Wifi problems with DD-WRT

Sup internet,
right now i got XWLSN official rom with newest modem XXMS2 and philz kernel on my i9100.
Also i'm using a WDR4300 v1 which runs the newest DD-WRT software (r21153 ftp://dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/2013/).
My problem is that I can use the Wifi with the phone for a while, but after some time the internet access is lost without warning.
The wifi symbol is still there and it's even in the wifi and the router DHCP client list, yet it can't connect to the internet.
I only notice that it's gone once i try to refresh the weather widget or use any other app that needs internet connection. At that point the requests usually just time out.
All my other hardware doesn't have this problem (smart tv, 2x notebook).
I also had a previous firmware (XWLS8 with earlier modem without philz kernel) and a previous DD-WRT build and experienced the problem as well with that setup.
Usually it happens after a couple of hours, everytime in the morning as well of course.
Seems to me like it tries to put wifi into sleep mode, doesn't completely cut the connection, but damages it in some other way.
Did anybody else have this experience? Any ideas on how to solve this problem? Should i try to give the phone a static internal IP perhaps?
yeah. same problem, but with openWRT - for all stock 4.1 roms so far. sometimes after a few minute of deep sleep, sometimes after hours, but like yours mine is always stuck in the morning. it does not matter whether 2.4 or 5ghz is used.
as a "workaround", i completely turned off wifi as my mobile contract has unlimited data.

Strange N-router Wifi problem 4.4.2

Hi guys,
Looked for an answer on this forum, no luck....
Problem,
When connected to an Wifi N-router, my wifi works for an certan amount of time and than drops. Wifi says I have a full conncetion but all my apps say there is no internet. Manually set Wifi on and off works until the connection drops again.
The strange thing is that it is only on N-routers. When I put the mixed mode on, it works like a charm.
But the problem is, Wifi is so slow on mixed that it is no option for long term.
Also it looks like even some routers with mixed on, makes the wifi drop. On my ubee modem every mode drops the signal, on a older linksys modem mixed (b/g/n) works.
Solutions tried:
- Got a new phone, same problem
- Factory reset, same problem
- Disabling Wifi power saver or any battery saver, same problem
- Change Wifi direct name, no luck
- Try apps like wifi repair, or signal boost, no change
- Static Ip adress, did not work
- WPA, WPA2, WEP, no luck.
- disable sleep on my phone, no luck
- Reset the modem, even factory reset the modem, same problem
- Problem was still existing after Firmware update....
I think I tried almost everything. Do one of you have the solution?
Phone
Acer E700
Kitkat 4.4.2
Not rooted or anything...
Thanks so much!

The issue was driving me crazy since the update to KK 4.4.2. It was like disconnecting the Wifi but the Wifi was not disabled, just the Wifi icon turned grey instead of the green when you are actually connected. Well long story short, turn off your BLUETOOTH and it will not disconnect anymore from Wifi. It seems to be a 4.4.2 bug.
Yeah I know.. who would have thought that?
Anyways, this works for my Acer E700 for days now and I am pretty convinced it will keep on working. Before this I was losing the connection within half an hour (but when on the power adapter the Wifi wasnt dropped)
