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!

I have not noticed anyone mention this before, but anyone on the Telus Network who flashed CM ROM on their phone know that your network reports as "302220" and not "Telus"
I have a bunch of modems I'm flashing to test out the speed I get on mobile data, wifi, and signal. Over the past I've flashed maybe 15 different modems. I was suprised just now when I flashed "I9000BVJV2" and the network now says "Telus" and not "302220"
I've never really cared about it, but I've tried various things with files in the phone trying to make it say telus, for sole sake to see if I could make it say Telus. Atleast I now know that it's really no phone settings that I can change.

Edit: Seems to have fixed the whole 302220 issue all together, all modems I flash now show as Telus.
How well is the JV2 modem working for you?
wasn't that great... what Im doing is take a few modems.. throw em on my phone.. flash and use it for a few days and narrow it down to the better one.
I usually start with doing some speedtest.net tests... the best ones I've found were the Telus JL3, 450K down/400K up... LKG2, 250K down/260K up. LKG2 is the stock that came with the GB update.
Right now I'm settled on Testing out the JVS, KC1, KG3.... both the KC1, KG3 give me 550+K down/500+ up on the speedtests. It was nice constant too.
can you please post back whichradios give you the best battery life? at sfu or a place with a large roof, I get large amounts of battery drain from time without a signal. currently on cm converted i9000 from fascinate with xxjvk
KC1 has been the best for me, not much better then the others or the stock gb modem from telus... but it is better.
My SGSII i9100 came with the KI3 modem, which worked flaswlessly (6-8 mbps down). An upgrade to KL1 saw identical performance. However, the newer xxLxx modems that are included with most of the ICS roms are really slow. Not only are speeds dismal (50-150 kbps on a good day), the phone is basically unusable. Play Store takes 60 seconds or so to come up, if it comes up at all, browsing is beyond painful, news apps take forever to load, etc, etc. If I go wireless or flash back to KL1, speeds are back to fast and the phone is snappy. I have tried probably 20 different APN configs to no avail.
Any idea why the newer modems don't work on my phone??? Any and all help is GREATLY appreciated!
if you are really concerned about your data downloading speed, flash KE7, the best I ever used...
I am using KL1 and all is well now. Must be a Houston area issue with the LPx modems. Thanks for the reply.
Modems are very much 'black boxes' (to use Entropy's words), only Samsung knows exactly why different modems work well or not well on different networks in different locations.
It's impossible to say X modem will work well for all people on a given rom in every possible location. They don't work that way. Like you, I also got pretty crappy reception/data speeds with the newer L modems, so I've stuck with KJ1 which I've been using for 5 mths. Being on an ICS rom has nothing to do with anything.
The usual procedure to follow if you do ever have signal/connectivity/data issues is to simply keep trying different modems (being CWM flashable this is simple/easy to do) until you find one that works well with your carrier/location/etc.
I'm having nothing but headaches searching for this. Plus, I'm relying on the internet on my phone to fix the internet on my phone right now, so I've got very little on my bandwidth cap left this month. I'm hoping one of you can help me so I can stop draining my cap with searches that just make me tear my hair out (especially when the internet drops!)
I've got a common problem, the internet connection (and sometimes the entire connection) drops out constantly. In my searches, it appears clear that I need to flash a new modem.
I know I need to do it with Odin, that's fine. My problem is finding a download link THAT WORKS for a modem to flash. I'm happy to try a few until one works for me, but if anyone knows of one that will give me a solid connection to Optus, that would be a bonus.
I'm running Cyanogen 9.1.0 (4.0.4).
Baseband is I9100TDVKF2 (and I assume the "T" there indicates that this was originally a Telstra phone, which it was).
I'm rooted.
I'm unlocked.
Thank you!
Read/search through this thread. Plenty of posts from people at various times mentioning modems which work well with specific networks. That will give you a good starting point.
Obviously look for posts from people who tested X modem with Optus & found it worked well, search for said modem, flash it, test in different locations/preferably over a couple of days to get a feel for how it works for you. If it works well, problem solved. If not, try another. Repeat until you find one that does work for you. Sometimes people using the same modem on the same network can have varying experiences due to carrier side issues (carriers using different equipment on different base stations, congestion issues, etc, etc), so tho most people find certain modems work well with certain networks most of the time, this isn't a given.
To be perfectly honest with you, that sounds like carrier-side/network issues to me.
Ah, thank you!
This is the link that I so desperately needed.
I've flashed DULP4. Here's hoping it works!
Thanks again!
You're welcome. If you're still having probs after testing, post to the AU thread I linked to in my PP & someone using Optus should be able to help (eventually).
All good, it seems to have done the trick. It's much more stable now. Cheers!

Good man
P.S. Mr. Bungle is the best. Good choice of name! Ars Moriendi is one of my all time favorite songs.
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?
Sent from my SGH-I777 using xda app-developers app
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.

Hello people,
For the past few months I'm having this issue which I find extremely [email protected]!!
Every few minutes, my phones just loses internet connectivity - the 3g signal appears to be normal during all the time, thing is, whenever I try to use any internet application - it just hangs. and then, after a minute or so, connectivity is back(again, for a few minutes).
I have tried flashing so many versions of modems - some improved it a little but most of them didn't help at all, or even made it worse.
Hopefully someone could help me with that as I'm that close to give up on this and buy a new phone.
Thanks in advanced.
Nir.
Which firmware are you running on your phone? What modem do you have right now and where do you live? Do you have problems with all apps that use internet-connection? Do the problems dissapear when you use wifi?
Just some information would be usefull

Yop.. forgot to mention a 'few' things...
Model: GT-I9100
Rom: RootBox V3.8
Kernel: 3.0.31-CM-g7ce58e6
Baseband: I9100DXLPB
Android version: 4.2.2
I live in Israel, bought the phone in Thailand.
I tried flashing all available Israeli modems(from various cell phone providers) - none helped.
Problem disappear when I move to WiFi - as 3g connectivity moves to background...
Thanks.
I assume you've read the Rootbox threads to see if other people experience signalproblems?
Did you compare the connectivity with other roms? Stock-based roms for example...

I've been hovering the internet for weeks in search for a solution..
That's not a RootBox issue in particular as I tried using various roms...

That seems quite weird.. The only thing I can come up with is 1) a hardware problem, or 2) you live in an area where the signal is crap
Hopefully someone else knows anything.. Good luck.

Neither of them thanks anyways.
Anyone else...?
If you've only tried flashing the modems bundled with stock roms from Israeli carriers, you haven't done nearly enough. There are literally dozens of modems available, you need to start flashing as many as you need to. This isn't going to fix itself magically.

I haven't flashed only Israeli modems but others as well. I've tried around 20 so far...
Question is, which direction should I choose? should I look for Thai modems or IL?
That depends. I know Israeli carriers sold (still sell ?) the I9100T, are you sure you don't have one of these ? If that's the case, I'd be trying modems bundled with roms released by the Australian & NZ carriers which sold the I9100T (I have one), and yes, the Thai ones as well.
If you do have an I9100, then keep trying any/every modem you can get your hands on. If it's not a carrier-side issue, this is really all you can try, unless you want to start messing around with RIL's as well. I've not found any difference in connectivity doing this personally (tho many people have) but if you get to the point of trying every single modem & you're sure it isn't a carrier issue, you might as well try. But I would leave this till last given many people find their connectivity messed up even worse by flashing an incompatible RIL.
