data connection broke despite full bars - Galaxy S II Q&A, Help & Troubleshooting

hey there,
i am on cm 9.1.0 now. i was using nightlys before and before that the latest nightlies of cm 7. since the may- or june-nightlies i experienced some problems with my data connection (3g or H). despite full and blue bars in the statusbar with an 3g or H, sometimes i did not have any connection. i did not have those problems with wifi. and sometimes, when i was outside and surfing, the connection broke off from one page to the other. in some cases entering flightmode and turning it off again helped. but not always...
could it be that i need another modem-fw?
how would i do that?
where do i find my current version?
tyvm!!
ps: see my settings:

MIUI Connection Drops

I'm using the latest MIUI official release as of the date of this post. I keep my phone in 3G only mode due to poor connection at work. At home connection would stay in 3G anyway. Works fine on touchwiz and cm7 roms.
On MIUI I lose all connection to Tmobile. Not just data. Sometimes it comes back in a few seconds, sometimes it requires a reboot. Tried 2 different modems that work fine usually. Anyone else or am I alone in this issue?

[Q] SGS2 wifi issues after recent update to ICS...

Hey guys,
Just updated my SGS2 to ICS (see screen shot for version details). While im still getting used to a few of the changes, i have noticed a reasonably annoying bug which is causing my wifi at home to drop out. The phone will not hold a stable connection.
I updated my phone while at work, then when i got home it did connect to my network with no hassle, but after a little while (maybe 30 mins) i noticed that i kept getting notifications that i have connected to my home network. so it seems that a connection to the home wifi network is made, then lost, then found and re-established, then lost again. I have observed the 're-connection' can be as frequent as every 30 seconds, but sometimes it will hold the signal for up to 10 minutes.
the wifi signal strength is strong, as i do sit quite close to the router.
does anyone have any similar issues to me? Anyone know of a solution?
Thanks heaps for any help.
ps: you will notice from the screen shot that i have installed Wifi Fixer from the market, this did not help stabilize my connection.
Thanks again.
hmmm
Have you tried manually setting your network values?
I was having this issue as well using my phone in DHCP mode, but when I assigned a static IP, it worked great.
On a side note, what router are you using?
Gday mate,
thanks a lot for the reply. I changed the IP setting to static, though i didnt have to assign one. does that sound right?
Anyway, it seems to have improved the stability - i havent noticed any more drop-outs. Ill keep and eye on it and let you know.
I'm pretty sure the router is a Netgear DGN-2000, but ill confirm that. We also use a WIFI booster.
Thanks again for your help mate.
Same problem I think
My phone got ICS recently. It worked no problem in my sister's flat but now in my aunt's place. Doesn't work, it will connect with the router. It will work for about a minute and that's it. No more internet but still connected. They use a booster as well and this problem of wifi connection issues is common it seems.
They only way I've found ti help the problem, forget network, clear internet cache in applications and restart the router

[Q] Wi-fi indicator not showing data transmission

Hello everyone,
Today I flashed the newer I9100XWLP8_I9100XSALP4 (coming from the old LPQ firmware) FW, doing a factory reset/wipe and cache wipe.
I did this with the hope the wi-fi not working / not coming up from sleep problems would go away, and although I haven't tested more extensively, it seems they have.
However, I am noticing now that the wi-fi icon is not showing activity when I know I'm using the Internet (normally you see the down/up arrows blink). Any ideas why? I know it's not a live or dead situation, but I'm curious as to why this happens. It is also not cool when you have internet issues and you don't know if you are actually transmitting or not (useful to detect your modem is down for example).
The data icon does not seem to be affected by this problem as when I turn off the wi-fi, and the data icon appears, I can see the download/upload arrows flashing showing data transmission.
Thanks for your help

Data connection goes grey when screen off on 3g

Currently using Slimics 3.8 with fluxxi kernel
First of all I know that grey means not connected to google servers so the problem is this:
When the screen is off and idle(no data transfer activity) for 10-15mins it will lose connection to google servers without fail despite full 3g signal bars, resulting in push messages not being recieved until I wake the phone and the connection turns blue again.
And this only happens on 3G/H+, wifi has no such problems
Anyone faced the same problem and have a solution for this? Have tried different modems, kernels, 3G only etc.

Check under Slim settings to confirm data management when screen is off is not enabled (under power)

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.
