(Help) signal problems - Galaxy S II Q&A, Help & Troubleshooting

Hi I have had my galaxy for a few months now and just wondered if anyone else had the same problem.
When I connect to the internet it flicks over to H connection then straight back to 3g which is making downloading big apps impossible.
If anyone knows a fix it would be much appreciate.
Thanks

Connection completely dies

Hey folks,
This has been a problem for sometime. Every now and then my x10 will completely drop connection, wether its 2G or 3G. The signal bar shows a little X sign next to the bars. Sometime it will do it when im downloading apps ot browsing the web.
Any ideas or fixes?
Cheers Sean

Use titanium backup and freeze the se backup utility. This is usually the cause, if so remove if you wish.

had exact same problem, on both o2 and unbranded fw's. can't seem to solve it, thinking it might be hardware prob.
might give one click root a go and try removing se backup like suggested above.

hasn't made a difference here unfortunately. doesn't seem to be related to battery temperature either.

[Q] Has anybody realized there is a problem w/ setting call forwarding when on WiFi?

When on cellular data, this works fine. But when I'm on Wi-Fi, it doesn't work half of the time. I've tried different modems, and the problem is always there. Also, I realized that it takes the phone three times longer to send a text message when on Wi-Fi than it does on cell network. Anybody experiencing similar problems?

Edit: forgot to say - lack of cell coverage is not an issue. H+ available where the problem occurs.

Why is my WiFi so slow at work?

It Works ok if im less than 5 meters away from server. But anything over that and its unusable. I work about 10 meters from the server. And I get at least 2 - 3 bars of signal out of 4. And I can't even post a comment on here. The speed is very fast for about 30 seconds and then ridiculously slow. It also struggles to connect. Tries about 3 or 4 times before it connects. I'm running cm10 on s3 but have this problem on stock, omega and checkrom. I had simular problems with the s2 aswell but not s1. I don't want to use wifi kill as its my work and it might not solve the problem. Is this the s3 working on networks with multiple apns? Is there a code I can call to turn off power saving ?? Can't force to 5ghz either.
Some advice would be massively helpful. I am getting very frustrated.
Thanks in advanced

S3 Signal Issue

Just wondering if anyone can help with a 3G issue I appear to be having.
I generally get great mobile internet signal, but today it keeps dropping out. If I select GSM only or WCDMA only then I can maintain fast mobile internet speeds, but if I select GSM/WCDMA (Auto) then my signal drops to 2G.
Signal in the area is fine for everyone else on the same network.
Has anyone else experienced this or know how to resolve it?
Thanks in advance

Make sure its not your network problem first

Checked, and it's not a network issue

Funny thing is, i have the same problem.
I got great mobile signal on stock ICS, full bars. Until i flash another ROM, ARHD 13 to be exact.

Try updating to JB if it's a software issue that should sort it.
Sent from my GT-I9300 using xda premium
I think i found the solution.
I'm on ARHD13, with Phenomenon kernel. I flashed other modem, for my region, that is LH1. That's when i got terrible mobile signal.
Then i went back to Phenomenon thread, and found out that he's using XXDLIB ramdisk. So, i flashed XXDLIB, just to test it out.
And it worked! My signal bar is full again.
