Signal Drop Issue (when internet data is ON) - Galaxy S II I9100G Android Development

Hi to all,
I am having problem when internet data (edge or 2g) is on my signal drops.
This happen after screen is lock and I return from lock screen, signal drops and it comes back after a minute. It happens most of the time, and sometimes when somebody calls or send sms to me I don't see anything and it don't shows me also after signal comes back.
If internet data is off this never happens.
Also to mention when I was on 2.3.6 version, I didn't have this problem never, but since I updated to ICS 4.0.3 is happening also with CM9 same problem.
If anyone can help I will be really thank-full.

Does anyone know the significance of greyed out network icons?

I upgraded to R3A last week and so far everything's gone smoothly.
The only thing that's bugging me is that the network icon (H) spends most of its time greyed out (see screenshot). I only ever saw it in that state briefly in previous firmware.
It doesn't seem to affect connection or call quality. It's not indicative of a bad signal, as it'll still go back to 2.5G when 3G is lacking. The resulting G will usually be grey as well.
Presumably it means something's less than optimal, but I can't find any info about it anywhere.
Clues anybody?
Are you sure you are able to connect to a data connection, for web browsing etc? Because the last time this happened to me, i was not able to connect, and had to do a hard reset to get it fixed.

Data connection works fine. There appears to be no issue with functionality of anything.
The set of "custom" status icons (colored ones) doesn't contain icon for HSDPA (or something like this, dataconnection available in you location) so it is shown as standard icon (only black&white). I bet if you have only EDGE or GPRS available, there will be the same icon as the others are.
it should mean that data connection is unavailable at the moment (because it can get back in a later time) or something is wrong with your data connection (that is why we have sometimes to reset the phone to make it work back).
Guys,
I have a Xperia for almost one month, and last night it suddenly stopped to be connected with the network. I tried to connect manually, and it worked, but the calls still couldn't be done! One hour later, the same situation started again and my phone can not connect to the network.
I don't know what to do anymore, I have already hard reset the phone, and nothing happened!!
Help me!

I get exactly the same thing, running Jacks latest lite-ROM, based on the R3A. Connection icons are greyed out, but I still have an excellent data connection.
What's more is that after a fairly long call, the phone usually looks like it's in flight mode. However, if I try calling myself from my second phone it works just fine, and I can recieve sms-es. But, I cannot send texts or call out, since the phone thinks it's cell-module is turned off. This always corrects itself after a soft reset, and usually passes by itself after about ten minutes. But the connection icons stay greyed out.
If I try to turn the phone-module back on, nothing happens.
Weird, innit?

[Q] Wifi Signal extremely weak

Hi guys, I use the captivate as a spare phone , and sometimes to browse the internet at home. I've noticed that recently the wifi signal has been extremely weak. I'm literally right next to my router and it's showing 1 bar of reception. When i step into the next room, i get no reception at all. I was on stock firmware at the time, I have since flashed to cm10, and the wifi signal is just as bad. Can anyone help please?
I'd suggest you try a different kernel. Also, you could try to delete your saved network and re-connect to it.

[Q] Wifi Cycling

I'm on Viperone however I remember this happening on stock rom as well.
I live in a sketchy signal area where the phon can flip back and forth to roaming. Each time that happens I loose wifi connectivity. If it cycles a lot it gets pretty annoying. Does anyone know of a fix for this?

[Q] 3g data hangs

Hi guys,
on my xt1068 (5.0.2 stock, no root, locked bootloader), 3g data always hangs when I'm travelling (e.g. Home -> Work). The only solution is to cycle the connection....
When I'm at home it works like a charm, even for an entire weekend
The mobile data icon remains "on", with full bars and H/3g symbol...but I cannot send or receive data.
Any ideas? As you understand this is really annoying. :silly:
Thanks.

I have the same problem but not all the time and I'm still on 4.4.4, I leave the house therefore disconnecting from WiFi sometimes 3G doesn't 'pickup' esp. if I turn off WiFi after it has moved out of range, like you it displays 3G or H but no data can be sent, the only way to fix it is rebooting the device.
Do you turn off WiFi manually after leaving the house? as mine only seems to do it if I do that.

Hmm, I always leave the WiFi on. I'm going back home atm and I just switched it off. Let's see if 3g stays active...(even if it would be the exact opposite behaviour than yours)
Thanks for the tip, I'll keep you posted.

[Q]Suddenly losing WIFI connection when phone is idle

Hello.
I am using my I9000 for a good while now and i am running cm11-20150901-SNAPSHOT-XNG3CAO3G0-galaxysmtd. Everything was running fine so far, but suddenly for some days now, the WIFI connection somehow gets lost when it's idle.
When this happens (and i don't know on what timeframe it does) and i activate the phone (pressing the home button) the WIFI symbol is either shown and then disappears or is already gone - but then after some seconds comes back and WIFI is on again.
Yes, i do have the setting for standby WIFI on always, so this should not happen.
Does anyone have an idea what could be the problem here?
Also i do have a fritz.box 7390 which supports a 5GHZ network - does the I9000 support a 5GHZ wifi? Maybe it's the router that's causing the issue an switching to the 5GHZ might fix it - but so far i could not see the network when it's on 5GHZ.. So i guess it's not supported but thought i might ask anyways...
Thanks!
