[Q] MODE/Radio issues - No data/No internet connection SamsungGS2 - Android Q&A, Help & Troubleshooting

I have a Samsung Galaxy S2 with Android 4.0.3 XXLPQ.
It's rooted and now has CM9 installed.
Unfortunately for some bizarre reason I have no internet connection.
I've installed a different modem and it hasn't fixed the issue.
APN settings are correct (I've spoken to my network).
Sometimes it works absolutely fine then after a few moments it just won't load anything and I get a 'No internet connection' warning.
Apps won't work either due to no connection.
However I do have a 'H' and sometimes '3G' next to the signal bars.
WiFi is working fine.
Have full signal..
Running out of ideas/options.
I've started from scratch and wiped everything several times and re-flashed xxLPQ but still nothing.
Help!

Same issue

[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] -Device- WiFi problems after changing roms

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] ICS Wifi Disconnect?

Every time I flash a ICS rom my wi fi becomes inconsistent and constantly disconnects. If I go back to any rom with 2.x.x its fine. I tried the Wi-fi fix but that doesn't seem to help either. Any one have any suggestions?
Try another Modem Set ?
I use KI3 now, it works very well both wifi / 3g.
As I know , ICS roms have lots 3g connection problems, but not much wifi problems.
Have you tried diffrent router?

3g data transfer issue CM9

I have problem with getting data transfer working on my SGS2. Im using CM9 latest nightly, CM9 kernel and XXLPS radio (already tried few other). I cant get data transfer, my phone is connecting to network provider (which is Orange Poland) i have "H" symbol for few seconds and then it turns into 3G but the icon always stays grey. I tried multiple APN settings so i dont think APN is the issue here. I have tried stock rom and everything works fine there (same APN as on CM9).

[Q] Strange WIFI connectivity issue...

Hey guys,
OK Ive got a strange problem with one of my Galaxy S3's!
It will not connect to some WIFI connections! It will say 'Obtaining IP address' then 'Failed to obtain IP address' and then loops itself doing the same thing over and over...?
I have two S3's and my other rooted device is fine. The one that has the problem is running a standard O2 4.3 rom (Un-rooted)
My rooted phone is also running 4.3.
Anyone experienced a similar problem? I have had this problem with 4 or 5 WIFI connections now, including my home one which is rather annoying! I have tried the obvious and rebooted my router, which hasn't helped!
Any advice welcomed!

I've had issues with the quality of my internet connection being checked, and then the connection being killed due to "slow internet connection", even on strong Wifi networks. Solution turned out to be to uncheck the automatic network switch in the advanced Wifi settings.

How so, when I have an identical phone sat right next to it with the same version of Android and that phone connects perfectly?
The only difference is one phone is rooted, the other is not (Both running 4.3, just different kernal number and build number)
Well wifi is a function of the kernel .
