So I got my gs2 monday, as soon as I got home I rooted it and put cm9 on it. since then ive been trying lots of ics roms and leaks. it seems like on them all my data is terrible. Either incredibly slow speeds, or lots of drops where my data doesnt work. also im in america on tmobile, which means I only get 2g edge speeds, I know edge is slower but this is horrible.
anyone hve the same problem?
This problem is mentioned in almost every ICS thread, also with suggestions for fixes.
FYI, I am in the UK and my data is fine on CM9.

thanks.
im sure some of it has to do with me having tmobile so I can only get 2g speed. I love the phone but 2g is so bad.
I suggest to try diffrent modems

I suggest try a firmware that Samsung have actually released as opposed to a leaked beta buggy test rom .

Wow the selection of ROMs for my shiny new SG2 is amazing. I got mine from Expansys and was going to stick with the stock ROM but the constant switching from 3G to H+ was driving me nuts and I would lose data connectivity every few seconds. As a result I decided to give a custom rom a try. Right now I have the Cognition S2 rom installed and will test it out for a few days but I was wondering if some of you have already gone down this path and found a good/stable rom for AT&T. Most important to me is stability, battery life and reliable data/call connectivity.
Turn off fast dormancy *#9900# been with Cog for awhile and loving it.
There is no Best ROM, different stokes for different folks and all. You really should just test around and see what works best for you.

I guess I shouldn't have said "best" - what I really meant what - looking for some success reports from people running particular roms/modems with AT&T. More often than not reply posts are from users outside of the USA so I was finding it tough to gauge issues here in the states. Of course this is to be expected since none of our carriers are selling the phone yet.
Illicit Hero - thanks I did turn off fast dormancy based on the recommendation in the Cognition instructions.
im with fido, which is rogers which is AT&T and I cant say there are any problems with any of the roms. I am however using Criskelo at the moment without a single problem
ROMs are generally non region specific and the most you may have todo is put in the correct apn settings for Internet and mms, but there is a thread for at&t apn settings so you should be covered there.
As far as modems, just work your way though them till you find one that works well for you, your best bet is starting the with newest and working down till you find a good one.

^ what he said. There is no region specific roms. All roms work fine, just enter the apn if it doesn't register automatically.
I use leomar rom for stock, it has every possible customization and theme available thru rom kitchen app. And then there is cm 7 for pure android fun.

Well said! I'm on AT&T and KH3 modem is working very well, then again, I can't remember a modem that wasn't good with the exception of KG1.

On 3UK I have found all but KE7 and KH1 have been trash for me
Download speed wouldnt top 100Kbps vs 200Kbps up! and poor signal.
I noticed E2 is way faster. BUT big but, E2 has way worse reception.
Am i the only one?
I was on Jersey Shore today and I couldn't get any data working.
If that is the case for you, then you could flash a different modem I suppose.

I've noticed way faster data speeds on E2. I used to see about 2 down, now I see about 6 down. And I've had no signal issues, always 4 or 5 bars. Afaik, different modems can give vastly different performance for different people. All depends on your area and what not. Just experiment with the various modems. I'm just glad Samsung finally got one right for my area, as I've only ever seen about 3 down on any phone I've owned until now.

The AT&T version of both of those modems, which is all us Canadians have access to thus far, has, for me, had much worse data speed numbers (non LTE anyway) on the Telus network than the stock GB Telus modem.
The E2 modem is, in my very non scientific testing, slightly slower for us here in Canada. (again, HSPA only, no LTE coverage here yet)
I'd really be interested in understanding what is actually different between carrier modem implementations. I noticed a similar speed differential in the stock modems.
I tried adjusting the RF preferences but that doesn't solve it. Its almost like AT&T doesn't have the same implementation of HSPA+ as the Canadian carriers.
I say all that with some degree of confidence in the numbers... having installed a variety of ROMs n modems and the results from the stock Telus modem are consistently better when I can use it.
Currently on the One Beta and associated LE2 modem, it shows very wonky "bars" by times...like none, in what should be solid five bar area.
My fourth floor office which never wavered from five bars on stock.. Consistently now shows any where from 0 to 3... But it still transmits and receives calls and data.
A buddy of mine is testing the Telus 4.0 release with Premium Suite... so in any event, it shouldn't be too much longer.

is it really that much faster? ive yet to upgrade from UCLD3 because its just running fine, wanted the next time i update my phone to be the last (offical ICS since i doubt we will get a update any time soon after that)
I noticed a big difference in speed. UCLD3 used to stutter a lot and freeze up from time to time for no apparent reason. Haven't had any of those issues with UCLE2. Also, bugs that annoyed me in UCLD3 were fixed in UCLE2. I don't see any reason not to flash UCLE2.
I've been having a bug on ucle2 where I cant keep a wifi connection for in app downloads resulting in the download stopping I've tested on multiple ucle2 roms and confirmed no issue on ucld3 not sure how I got so special because I haven't seen anyone else report this that I know of

That actually happened to me. I reverted to D. Seems not as crazy fast but stable. With E I got 1mB (that's bytes) per second. D tops at about 600.

Hello. First of all I'd like to state that this is my first android device and I am still learning the whole process of rooting and flashing ROM's so bear with me.
So to my question. I installed BlackStar V1 yesterday and I noticed when performing a speed test that my 3G performance had dropped significantly. I have a 1Mbps download bandwith plan from the best provider in my area, and got full speed at 60-120ms with my previous phone and with stock and Omega V4 rom's with GS3 at all times of the day. However after installing BlackStar my latency tripled and download speed cut to third from the 1Mbps even at night when the network is less crowded. I can manage when I'm home or at work since the wifi works fine, but when on the move handling large e-mail attachments gets frustrating. Does anyone have an idea what might be the issue?
I haven't tried to restore my Omega nandroid backup yet in hopes this issue might get fixed somehow, but am forced in couple of days if it's not, which is a shame since i really like this rom .
Unfortunately I do not have screenshot of my speedtest result before installing BlackStar.
I have a little different speeds in helsinki with stock rooted ROM and fastest saunalahti multi-sim
Yeah that shows that the stock works fine, I actually realized to check the history tab and you can see that 3G has worked for me correctly in the past.
Could it be that the creator of the BlackStar has changed the stock modem with a different one that doesnt work well with finnish frequencies?

Seems like it was indeed a modem issue. Fixed after installing the new XXLF2 modem.

So last night I updated my s3 to the latest UK firmware, XXBLG8, And I can't tell if my problems stem from the latest update!
After the update many apps wouldn't open and I'd have to do a battery pull to sort out each individual app that refused to load, everything's fine now, however, my data connectivity seems to have worsened considerably, even with full signal strength and HSPDA nothing will load, the browser shows errors that I'm not connected to the internet and apps such as the Play Store and Speedtest won't connect.
Anyone else experiencing this problem? Would I be able to flash back to an earlier firmware using ODIN? (I'm new to the s3 scene, just jumped ship from a Desire HD and haven't yet fully got my bearings.)
Thanks guys!

only problem i have noticed is that speedtest does no longer work but everything else perfect. Infact my hsdpa connection is much better on this rom. you can easily downgrade your rom back if you wish just follow this excellent guide to flash via odin.

Hmm, I suppose it could be the area I'm in, but it's usually fine where I am. I'll give it another couple of days and test it in other areas to see if the problem persists.
I've upgraded via ODIN before, just wasn't sure if there were restrictions on downgrading etc, I'll give the thread you linked to a good read now, thanks!
Try changing Modem BULF1 for starters .
I find the last two updates modems are very poor .

I am also on the 8 firmware and so far it's good.
looks like speedtest.net have changed there site slightly if you goto site with mobile agent set on browser it redirects to the play store to the speedtest app, change browser to desktop as long as you have flash installed all is fine. I believe this has been done site to the up and coming removal of mobile flash

Thanks, I'll give it a go!
So I decided to bust out my Desire HD, I remembered I still have a month left on my old contract before it gets terminated, checked the data connectivity on there and I seem to be having the same issues. Looks like it's a problem with 3 in general rather than it being my s3. Which is good news for my s3!
Must have been pure coincidence that I started having these issues right after upgrading, however, I tried a few new modems and have been getting better signal (no change with the data issues) so at least I've taken something away from the experience
Isn't there an issue with 3 UK branded ROMs experiencing network issues when you flash the unbranded ROM? I think you may need to flash a separate modem, Google it, I may be wrong.
I'm on 3uk running blg8 not had any problems making, receiving calls and texts and my network is fine on both wireless and 3g

It seems to be working pretty well this morning on both my s3 and DHD, and Frostfree I'll have to check that out, I've already flashed a few new modems and I'm getting better performance so that might very well be the case!
I'm in Folkestone (south east coast)
I am on BLG6 with Cyanogen Mod 10 latest rom and so far I have great speeds (4-5Mb) on speed test app.
Will try flashing BLG8 when i can find a download link. I just want the modem to flash not a whole rom cos i am loving JB on the SGS3.
Ive been looking around throughout the forum and I cant seem to get a grasp on which Radio gives the best speeds and what rom should it be running.
Should it be a Stock Rom or should it be a Custom rom?
If so, Gingerbread, Ice Cream Sandwich, or JellyBean?

CyanogenMod9 and included kernel are stable, good set of extras added to ICS, the modem (I think it is stock), works well. Seems like it is still a little early for CM10 (still some areas that need to be imporved). Only drawback is that it does not include Touchwiz Intercase however, 3rd party apps bring back the pen functionality (for notes and drawing).
Someone posted a link to a Google map that shows best radios FOR YOUR AREA. I recall reading the post and seeing it but you have to use a PC for the search. Look around for Google radio locator etc. I'll look too

I've flashed stock and custom gingerbread roms (touchwiz), stock and custom ics roms (cm9, stock touchwiz, aosp, aokp), the t-mobile note rom, and various jellybean (cm10, slim bean, etc.) roms. I've flashed every radio modified for use with t-mobile from all the modem threads including the t-mobile note radio. At the end of the day, cm9 rom (stable or nightlies) / ICS blaze modem combination works best on my phone.
I live in NYC. I consistently get about 15mbps down / 1.5mbps up (sometimes 2.5mbps up) with this rom / radio combo. The only issue I have is that a phone reboot causes my speed to drop to around 600kbps down and almost nothing up (like 25kbps).
Reflashing the radio and driving around to allow my phone to connect to various cell towers gets my speed back up to 15mbps down / 1.5mbps up. For the life of me I don't understand why. However, if I don't do this, my speed will be stuck at 600kbps down / 25kbps up indefinitely. The good thing for me is the cm9 rom on my phone is pretty solid (I rarely have to reboot) and I commute everyday so (if I have a reboot) it's just a minor inconvenience until I start driving. Then my speed comes back.
radio combo
I Myself installed Saurom and tmobile radio vlk1 i beleive its called. .. I got it from zedomax,s site....rootgalaxynote.com and it seems to do the trick. ..my best was 13 down and 3 up. ...........not sure if this is the best combo but i tried a ics stock rom for note and blazeics modem and my speeds didnt come close. ..... But dont get me wrong id like to run a custom ics or jellybean rom and grt good speeds but i find gingerbread and the radio thats on zedomaxs site runs hella faster...i have adw ex i run and its good enough for me. ..if anyone knows a awesome ics rom with radio that has super speeds lemme know. ..i useually run AOKP roms... Word good luck people
