hello all so in my other post I mention I briked my phone so here it is.
I had to flash a stock jellybean rom with odin and now my wifi seems to only pick up certain frequencies.
example I have a F3 that shows up all the wifi around it but then my note doesn't lucky for me my work wifi is one of the only ones it picks up I think it is due to the radio/modem any one have any ideas
thank you in advance

Hi Guys,
I recently got the SG2 on AT&T (i777) and the first day I had it stock I was getting consistent H+ connection in my house and pretty much everywhere I was going. I ran the speedtest app a couple times, and I was averaging 2.5-4 mbps downloading which wasn't too bad.
That same night I rooted the phone and flashed Phonebreaker 2.1 rom following the correct steps (Not my first time rooting/flashing roms, I've done it to my Tmobile SG2 a few times). However the following day it seems my data connection has become inconsistent and speeds have slowed down to a drag. The indicator on the phone can never stay on H+ or even H..it consistently cycles from H+ to 3G to H (tried it in same locations as the first day with the phone). I ran the speedtest a few times and my download speeds ranged from 300Kbps to 1.6mbps if I was lucky.
I tried looking around in all the forums, I re-did the APN settings found in these forums, I troubleshooted with AT&T but to no avail.
Anyone have any suggestions? Would much appreciate it as I love this ROM minus this data issue I'm having.
FYI - Stock only shows H+ even if your not actually on it.
Its an illusion AT&T does to make the user think they have great connection everywhere.
Also try flashing a different modem, that might be the issue with your speeds, cause I changed to the leak's modem upon many request.
Thanks LiLChris06!
I tried the KH7 modem which did nothing, and I tried the KK6 which seemed to improve it a bit. I went into AT&T today and they said maybe it's just a defective phone and were willing to switch it out, which I might do.
However I love this ROM so much, is it available without the custom modem you added or with a different modem in the install rather then the UCLK2 I think you included?
Thanks

Hmmmm...what you mean by is it available without the custom modem? Maybe Im reading it wrong. As you know, because you said you have tried different modems, there are many different modems you can try. Shouldn't matter what modem the ROM comes with. Think there is a modem thread around here that has some good info. I think Task also just uploaded the the new LC5 Modem
I should have worded my reply a little better, and it might come across as a newbie question but basically I was wondering if that rom came with the stock modem the i777 comes with because when I had the phone the first day stock, the data speeds were pretty reasonable (3-4 mbps/downloading).
Wasn't sure if flashing different modems other then the one that came with the phone originally would help out my issue, but I suppose it doesn't hurt to try. I did find the UCLC5 modem so I'll try that in a few minutes along with the other ones I haven't tried. If no luck, I'm going back to AT&T to exchange, probably defective phone like they said.
Thanks again for everyone's help
Sweet, found a solution!
I tried all 7 different modems under the same conditions, KJ1, KJ4 and KK6 were around the same ball park. KH7 and UCLC5 were a bit slower but close to each other, UCLC2 was by far the worst..and the winner was KJ2, big difference.
Thanks guys!

Is it normal that the SGS2 i9100G Model has a very weak signal reception, not only with WLAN but also with normal mobile phone connection (Talking etc.) ? On my previous Motorola Defy I didn't had these problems. Now everywhere the signal is weaker than before on the other phone.
Is there a good ROM & Kernel (too many to know which is best and which not) that could currently help fix that and make it a bit better again ?
Thanks in advance.

try flashing diff modems ,one might help...
Unfortunately I am not so much the "flashing" kinda guy, only what I need to. I wouldn't know where to find these files or which to use for the G Version. I suppose I need the international versions for that, since I am from Germany, right ?
I bought a sgs2 about an year ago and since the very first day I had problems with receiving calls and even making them.
If I'm sitting at one place everything's good but as soon as I move something goes very wrong and the call drops.well if I'm moving I'll be glad to even get or make a call although the signal in the notification shows full.
Now on the stock ROM,the signal strength is about -61dbm 19-20asu but on any other ROMs that I've tried it never goes beyond -89dbm 11-12 asu.
Next I read a lot about flashing different modems that might solve the problem but no.its like nothing seems to work.(BTW I tried a lot of modems for my country and others as well and used getril also to match the ril's as I read about that in forums.)
While trying go flash a modem i lost my imei and baseband.
Luckily I had a backup of the stock ROM and when I restored my phone at least I got the imei and baseband but whenever I reboot my phone for something,the problem's back.
Im on stock ics 4.0.3 with siyah kernel v4.1.5.
I'd be really very greatful if one of you millions of geniuses could help me.
If you need any further details in finding a solution I would provide it ASA I see what it is that you might want to know.
Thank you in advance.

I got a Razr Maxx that cames with 4.0.4 version already (got it from CLARO, claro rom 672.180.311) and since first moment im experiencing low quality from wifi connections.
i moved for 672.180.340, same quality, them for .350 and used a lot of cm10 biulds (d-wiz, crackerteam, etc...) all of them i got an unstable wifi connection. With CM10 i think was little better then others, but still worse them my DEFY and my OPTIMUS2X. after lot of times getting wifi connection droped i start to analyze it using this software that i use since my first android (HTC Diamond, android version 1.6) https://play.google.com/store/apps/...SwxLDEsImNvbS5mYXJwcm9jLndpZmkuYW5hbHl6ZXIiXQ..
when im 5-7 meters away from my Router all those phones still with -40db (total signal) and my razr maxx is getting moving from -80 ~ -50. it never comes on -40db and the changes have so fast frequency.
Can someone from brazil say something about this to me? did your phones act like this on wifi? im thinking to send it to support.
*maybe i post a video of my test later.
This question is "especially" for BR people, that not means "only for BR"
the only thing is that my phone is Made in Brazil. thats why i direct my wuestion to BR people.
Can Someone tell me something more about this issues??
I'm totally disappointed with the wi-fi on this device. I upgraded recently from a very basic android phone (LG P350) and it had better signal (which is unacceptable) . I've tried some tweaks to improve it but nothing worked. I'm almost convinced of buying a more powerful router for my home office. I'm not willing to install custom roms just yet, so I've only tested it with stock ICS from VIVO.
Let me know if you find something to enhance signal strength and stability.

Ok drunken, thanks for your opinion. Was thinking that was only on my phone.
I will try little more, probable using a dualband router and/or another cryptography like wpa2/wep (im actually on wpa-psk aes)
Will update here all results
Digitado pelos meus dedos.
Just to let you know, yesterday I had to flash a new firmware (new, but official, from TIM) because beats audio screwed up my phone. Wi-fi is better now, not perfect, but I get a nice signal in every room at my house, without random disconnections.
Of course by doing so I threw warranty out of the window. It was the only option is had, though. Sound was dead and video playback as well.

I have a Samsung Galaxy SII, the i777. I have rooted it and loaded ShoStock3. I love the ROM except I'm having trouble downloading apps from Google Play. The research I have done suggests that I need a better modem. I have downloaded and flashed six different modems. Each one just as slow as the last. I'm in Salt Lake City, Utah. I know that the location can have something to do with the modem as well. Does anyone have a suggestion on which modem would work the best? Also, if you happen to know that there is a separate problem and that it's not the modem, will you please let me know? Everything else seems to load fine, it's just trying to load apps from the market that I'm really noticing it is really slow. Thank you everyone in advance.

Modems are good in different places. What's good for me might be awful for you. Have you done a speed test?

You've already flashed 6 different modems, you should know by now which one is the best for you out of those 6.
If you don't like them all, try some more and pick out the best.
Have you tried KH7 or LL6?
Side note: why can't you use Wifi for Google Play?
You are I assume flashing modems for this device right? I only ask because obviously the i9100 modems wouldn't work for us. (And I'm pretty sure calls don't work with them) also, if you are flashing all these modems and they ARE for our device, and NONE are working properly, I would look at a fresh flash of the rom of your choice wiping everything again or going back to stock to eliminate hardware error possibility.
I did verify that they were all for my model and network. None of the six were any better than any other. I also noticed none of them worked on the 4G network. I tried to download an app to do a speed test but after 30ish minutes waiting for it to download on each modem so I could test it, I gave up.
Shoman94 changed to UCLL6 modem on his latest build. Are you using this one now?
Or you can select all the modems from here:
http://forum.xda-developers.com/showthread.php?t=1336958
They seem to be working OK, at least for me. I have tried at least half of them although I am still running ICS (CM9.1), not JB like you.

In the Settings of ur phone, since u r runnin SHOstock 3, do u have the Mobile data box checked under Data usage ? And do u have the "Set mobile data limit" box checked under Data usage (this could hinder u) ?? And under More settings/Mobile networks is the Network mode set to something Other than the "GSM/WCDMA (Auto mode)" (this could also be the problem)??

So, I un-rooted my phone but from what I understand, even doing that won't re-set my modem. It's still working slowly. My biggest fault here was not doing speed tests from the beginning and not noting down what my phone came with. If I could find what modem my phone came with, I would root and load it back on.
I really appreciate everyone's help and suggestions.
Is there anyone in Utah on the 4G version of the SII that could tell me what their modem is?

Check your APN settings, that can cause plenty of issus for data.
