very slow 2g speed - Galaxy S II Q&A, Help & Troubleshooting

Hi
I'm experiencing very slow 2g speeds these days I think it's modem problem because my brother who's using same network(vodafone) is getting around 3x speed compared to mine, both on same plan but he's using grand and he's on official rom and I'm on neatrom
How can I fix this? If new baseband please suggest me one especially one which works well in India - Mysore
Currently I'm on neatrom 4.2
Baseband xxms2

Switch to 3g.
Sent from the little guy

I got wifi in home so it's waste to spend money on 3g which is costly in India

2g, 3g or wifi? Which one is it?

Mate, staying on 2G is a viable option only when 3G has a poor connection and drains battery. The only difference is the speed with which pages are loaded and data is transferred. The only noticeable difference in the volume of data is if, on a good connection, you browse more pages because they simply load faster.
You may be referring to WiFi, which is another story.

Modem bad reception in Canada Galaxy s2

Hey all, i thought i would start a thread about an issue that many canadians seem to have with the GS2, it seems to have been beat to death but there is no actual solution.
Im currently using the GS2 with Telus, its a wcdma/3G/H/H+ carrier using the frequency 1900 mostly and 850 at times on the cdma network, i used so far KG3-KG6 i placed them in that order because KG6 is the latest i tried and has proven to give me better coverage but its still really bad..
I can connect to data but only outdoors or only when the reception is full bars, if i start to lose any bars there goes my data connection and i can no longuer use any services data/sms/mms/calls i literaly cant do anything..
This is a big issue as i know for a fact that you dont need a data connection to send sms. but it seems the galaxy s2 under the current modem firmware im using KG6 wont allow me to unless im on full data coverage...
My question is this, what is the best modem firmware to use according to the frequencies that i meantioned earlier 1900/850 WCDMA i dont mind using another country's modem as long as they are oriented towards the same frequencies that i need
My phone came from Korea and i know they use 2100/900 could that be the issue? Is my hardware oriented towards that? At this point anything could help and please feel free to post thanks

Hmm, I'm a SGS2 owner on TELUS as well and haven't had any problems so far, besides the GPS Lock Time which most people seem to complain about. It takes about 1 minute for the GPS to lock for me, but my data is fine. No dropped calls or sms problems here. My download speed as I checked last was at 8.31 Mbps down and about 2 Mbps up.
But again, having horrible GPS issues. Wish I could figure that one out
Sobai can u post your results to *#1234#
so i can compare my settings to yours.
I'm using KG6 on Rogers network and don't have fantastic reception either. For most situations it holds calls -- but buildings with lots of concrete I lose the signal completely. It's as if I'm not truly on the 850 band ... my G1 had the same problem until I flashed a Bell-specific modem, that solved the problem. I guess we'll have to wait until Bell launches the G2 here, we'll be able to swipe the modem again.
i have an imported gs2 that i am using on rogers and it doesnt drop calls, but i have had times in the past when it would show 3g but not download any data. once i turned airplane mode on and off data would work fine again. the best radio for me has been the kf2 modem in terms of not having the data stalling issue. i find that even if i show no bars of strength i can still download data with no issue.
if you are on telus i would make sure so set the wireless settings to 3g only so the phone doesnt try to look for a 2g signal.
KG2 on a Bell SGS2 on Rogers/Fido network in Vancouver.
GPS locks in seconds. no dropped calls. H+ all the time, never once saw a 3G symbol. no data dropouts.
over 7Mbps down on this network with the SGS2, when i had 1/3rd the speeds an HTC Desire. great reception in my office downtown, my apartment, everywhere i've been so far.
KG2 (not the stock canadian though), in Montreal on the Virgin/Bell network. So far no complaints on the data. Since I started messing w/ the firmware however, the connection is on 3G when idle and only switches to H+ when actually in use. From what i've been reading many people have been noticing this when flashing over the stock Canadian firmware.
On the other hand however, the GPS has been having a hard time establishing a lock (whereas it used to be quite speedy and precise before I flashed). Won`t be able to test whether this is a firmware problem untill the stock Canadian is released by Samsung.

Wow guys I appreciate the feedback I thought I was the only one with this issue! I will definitely give kf2 a try right now and I'll also download the 3G only data app and give it a try and I'll get back to u guys with some feedback. Thanks again
Btw I'm using, touch x 3.2 rom that has kg5 on and I did notice a little improvement in the reception but the data connectivity is still very spotty so I'll give kf2 a try but so far kg5 modem is definitely the best one I seen so far to use on telus. Btw anyone trying to use the galaxy s2 on fido, I was never able to get 3G at all to work I was stuck on edge.

Do you know how I would be able to set it up so that it stays locked on 3G? I tried the *#301279# trick and disabling hsdpa and hsupa with revision 99 but to no avail. Even if it shows full bars and 3G I still get no data connection and also I can't send or receive texts unless there is a data connection for some reason, have you guys had this issue??

i have never needed to mess around with that menu. you should be able to go to
settings
wireless network
mobile networks
network mode
select wcdma only
that will lock it to 3 only. if you keep having issues you might get a new sim card from telus as that might be causing you some issues
Do you have your apn configured properly for your provider? If it isnt your data definitely work. Other then that I havent had these issues in edmonton on kg6 or maybe I just dont know what to expect reception wise. I do notice it hops from 3G to hspa to hspa+ a lot so i switched to only 3g. If anyone finds anything that improves that or reception though I would be interested

This information would be great because I am also experiencing spotty data connectivity (browser loads data, stalls, resumes centuries later) which results in severe crappy data speeds of 0.8mbps down and 0.07mbps up (done on in-browser speakeasy test and speedtest.net app.

I wish there was a way to extract the modem.bin file from the bell sgs2 this way we could simply distibute it around. Someone should root their phone, install cwm4 and make a backup and we could simply pass the backup around so we could all have the modem
Bell modem has already been posted to the forum.

[Q] Unstable Network signal on sk17i - losing network all the time

Hello,
I have the SK17i and I'm a bit down by the bad network connection. I use GSM only mode, since UMTS coverage isnt that good as GSM coverage and with both enabled, its switching all the time.
Do you have similar problems?
A call breaks up, but I still got good connection displayed... 5 sec later, i got the yellow warning and no signal ... 10 sec later everything is back normal and I can make calls...
This is really freaking me out...
Do have this problem, too?
Is there any Solution?
Thanks,
Linkin
what software are you running? maybe that's the issue.
i used to have e-plus, cell coverage was ok, but internet was horrible.
now vodafone, good reception, good internet.
i'm running minCMsandwich, before that hybrom with x-kernel, never had problems with phone reception.
I'm running the stock ROM (*.58) at the moment!
I have o2 germany network!

Fully stock phones shouldn't have problems with baseband at all.
I will leave my mini pro since I can't really use it this way... I'm gonna give it a last try with the new ICS ROM but I'm not really optimistic...
Sent from my LT22i using xda premium
It looks like the ICS update fixed this problem!!! THANKS Sony... I love the XMP!
Unfortunately i have also a little problem with that.
I had poor bad network connection on GB... but both on official ICS and CM9 FXP123 its not much better...
baseband .72 is great. drain a lot battery, anyway
just had the same problem with ICS once... I will report back, how it progresses...

[Q] Orange UK 4.1.2 update?

Hi all,
Has anyone updated their Orange S3 to 4.1.2 through KIES? Does it include any bloatware or anything useful (unlikely).
Also, has anyone taken a dump of the FW?
Just wondering as I have not seen much coverage of this other than that it has been released, eventually.
Cheers
MS
I think most people on here will have flashed the unbranded firmware to be honest.
Could be wrong though....

You are probably right, I am running the latest and greatest stock release, but live in hope that Orange will include Signal Boost in an update, one day.

I doubt EE will go to the trouble of a bespoke radio firmware for their network, the XXELLA modem is working fine for me on EE with 12Mbps speed recorded on occasion (why bother with 4G when H+ is delivering that?).
I'd suggest you try flashing a few of the 4.1.2 radio variants to see if your signal improves, but this may also decrease your battery life.

Orange Signal Boost is a UMA application for Orange -- it allows you to make/receive calls / SMS over wifi when you have no signal. It was in the GS2, but not in the GS3, unfortunately. I was really hoping it would come out as well as I have practically no signal where I live unless I am right next to a window.

Likewise, it is a shocking oversight that they have not brought this out for the S3. I have to stand in my kitchen if I want to use my phone! Sometimes that doesn't work either, so I have an excuse to go to the pub (I get signal there!).
Indeed
XXELLA does give good performance and I have tried modems galore, but when there are many houses between you and the base stations sometimes you just need some help!
On a slightly off topic note has anyone tried the BT Smartalk app? Although its just for outgoing calls its pretty handy for making calls against your BT allowance over WIFI.
If only we could have a seamless phone / wifi handover for calls.....I live in hope (and know that its been punted as a future before)
And I completely agree about the Signal Boost UMA side of things, its was super handy in my S2 when I occasionally ran a stock ROM or installed while rooted, plus I could make calls on the WIFI on the Underground in London, I do miss it!

Hi I have been looking everywhere for answers since about changeling app data speeds and bandwidth allocation for tethering. I live in a new 4g HSPA area supposedly capable of 42mbps speeds on my galaxy S3 sgh-t999. Its rooted running the darth stalker ROM, the tweaks that come with and the NEW UVDLJA MODEM that came with yet daytime I get about 1.5down and very variable up with late night like 11pm or midnight 3mbps down same up. Is there a ROM somewhere or a custom and/or new modem that could help me? Maybe a file I could edit on bandwidth saved for phone functions? Lol I only the data! I am on T-Mobiles unlimited 4g data plan and get full signal. 4 bars of 4g at my house. Any suggestions?

Last ota update I did all of that and used mobile Odin pro for root to inject SuperSU into the stock 4.1 after a total reset. Since I originally bought the gs3 on any ROM, app, or build.prop tweaks the data rates have remained almost exactly the same. T mobiles network upgrades didn't change anything either. Anybody know who has the best/most use full data speed tweaks in their ROM? I was thinking of trying hellfire or illusions. There has to be something I can do with a rooted GS3, the new 42mbps network, and a constant 4 bars 4g! Any advice at all?

I would Definetly say Darth stalker X.1 especially if u flash Deviant 1944mghz OC CPU speed kernal. You have to download the Kernal desperately but it's worth it. Darth stalker is only for T-Mobile T999 so he is always up to date on our fastest network/data/streaming tweaks and tethering hacks. Dude is on it. Better than hellfire, xquizit, cm10, and even aokp in my opinion.

S3 Network issue! Slow internet! only GPRS.

I've Samsung S3 GT i9300 SHV E210 L and when I check my APN settings it does have LTE option under Bearer but currently my Telecom provider doesn't support 4g. However they do provide 3G with a great speed. I hv used it on other mobiles and it works great . It's just this phone gets only G when selected GSM/WCDMA automode. When I manually select WCDMA only it gets 3G but very slow speed and it drops out very frequently. The maximum speed which I have received is around 1 mbps only.*Please provide me with a resolution how I can I get good bandwith/speed. ?

Change modem,is the only thing you can do...control in samfirmware site what's your last stock firmware supported by your device,in you country with your provider. There you can see the base band,use that for looking for the right modem and try to flash it. The wrong modem can drain your battery or could kill your network
S3 Network issue! Slow internet!
And this phone is a Korean S3 with 2GB RAM and 32 GB ROM and it always warns me about data usage in abroad. I use this phone in India.
It gives me error like registration failed contact customer care. And ya my battery drains very quickly. If you can please give step by step process to fix this issue it will be great.. Much appreciated.
thanks.
Give me time start from samfirmware!

I'm sorry but we have 2 problems:
first,your device can't be a GT.I9300 because has 2GB ram...
second, on samfirmware KOREA doesn't exist,so i can't quickly know what base band is used in your country :/
Haven't you the stock rom??
