Network problems - Cycling though H H+ 3G - Galaxy S II Q&A, Help & Troubleshooting

Hi,
My Galaxy S II seems to be having data network problems after upgrading to XXLPQ.
When connected over data, the phone will continue to cycle through 3G... H... H+... and repeat.
The connection is very laggy and ping will have about a 3000ms latency as the phone just does this over and over again. I tried using an older modem and it didn't help.

I am on three network UK user on gingerbread and my mobile network is slow has been for too hours.

Looks like a good old 3g data stall/hang issue.

Me too facing same issue, Samsung needs to fix this issue.
ICS XXLPQ is not fully polished ROM, it has lot of bugs & its bit buggy.
May be the UK version releasing on March 19 will address this issue.
Needs to wait and check this out

I'm using the LPE version and I noticed this too, except its when I'm on Wifi. There's two arrows, pointing up and down, the one pointing down is constantly flashing on and off, like it's downloading sometime, the upload arrow occasionally flashes, but not a lot.

Did you guys disable the fast dormancy by *#9900#? If yes, try to enable it again.

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

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.

Stop switch between 3g and HSDPA/+

Hi all!
I have a Galaxy S2, rooted but running on 2.3.5 official firmware (XXKI3 / XWKI8)
I have a problem with the data connection switching between 3g/HSDPA/HSDPA+.
I have excellent connection when on H and H+, but as soon as it goes back to 3g it gets stuck on the "up" arrow.
Is there any way of turning off this switch so that it stays on H and H+?
I've had a look at *#301279# but as far as I can see I cannot turn of 3g through there (or stop the switch).
I've also tried turning off fast dormancy but 3g connection still gets stuck.
Any help or ideas are greatly appreciated!
Thanks in advance!
Siwan
You cannot turn of 3G and have H/H+. Just curious, when you swtich off H/H+ , so you are only on 3G and you have disabled fast dormancy, you still getting stuck?
I know this way you are loosgi out on high speeds, but does this at all works for you or not?
Thanks,
Vishal
Thanks for the quick reply!
Aha okay, well that's a bit annoying.
Yes I've tried with only 3g and fast dormancy off, but still the same problem; the 3g gets stuck on up arrow.

I would say it's an issue with your carrier. I'm with Vodafone Australia, and I have the same issue and even sometimes H staying on for hours.

Data connection hangs in gs2

Hi guys. Me and my wife both have gs2 and we both are on tata docomo 3G network. The speeds are good and this phone is awesome, specially for someone coming from a blackberry like me. However there is a peculiar problem both of us are facing. The data xonnection sometimes hangs on 3G and does not move to h or h+, and in 3g therd is no data transfer. The data transfer happens only on h+. That means for all practical purposes there is no data transfer. Sometimes it alsi so happens that the phone is showing the h+ icon but again there is no data transfer and i cannot access any internet related app. In these cases when the data hangs the only option is to activate the flight mode and then again reconnect. Then the data works fine. Off late this has started happening a lot. I have tried a couple of things like deactivating h and h+ and working only on 3g but to no avail. Can anyone help with this. I have not been able to test on other networks so i cannot be sure whether this is a device related problem or due to the network. Any help would be highly appreciated.
Regards

I am also facing this exact issue. I am on Airtel (India) network. For me, it seems to happen when I am at some particular locations, and works smooth at some other locations.
I just deactivate data network mode and re-activate it (long press power) instead of flight mode, takes only 10-15 seconds.
Don't know if rooting and using custom roms will fix this issue, because I strongly believe it to be network-related. I used to have similar problems with HTC Desire with various sense/AOSP custom roms.
He y buddy. But if ur on airtel and i am on tata docomo and we both r having the same problem, maybe it is not a network problem and is rwlayed ro some handset setting. Did u try the *#302179# trick. Did it work for u. Same problem in othe networks and for some of them this trick worked.

And by the way thanks for the data connection mode trick ( long press). Atleast it is a better way to make it work.

i have the same problem i.e data loses connection. after a fresh flash of stock rom and factory reset , it starts working fine for a week or so and then the shyt happens again . i can tell u , its not a hardware issue, it more like a software issue.
i m not good at android but wen i used to run squid on a linux machine as a proxy server , i recall i had to clear a log file to make data flow possible every few days. i think android has a similar issues some logs files build up or some **** like that.
Happening to me as well.
I always thought it was vodafone's poor network as my phone never downloads data when 3G is showing, it will only show upload arrow, then when it change's to H I get both uplaod and download arrows and starts working fine.
One thing I did notice though is when in Gran Canaria 3G was showing and working and data speed were ridiculously fast compared to here in the U.K
Surely this must be related to kernel used???
I have the same issue on my I9100 KI3, KF4, KG2 stock rom with either KG2, KF4, KI3 or KI4 modem. This is a combination of tower and our phone modem or kernel issue. I am having this issue with AT&T USA on KI3 and KI4 quite often in Champaign, IL. But when I went back to my country in Asia(Taiwan) 3 months ago, KI3 rom and modem have no 3G issue at all. I was on 3G 24/7 for 3 months without any issue there. However, I had the same 3G issue in Taiwan when I was on KF4 modem with KF4 rom when I first bought the phone. This is really a funny issue. I tried all the tricks and switching so many rom and modem, but 3g hang still happens to me with AT&T network. Now I am trying to lock the WCDMA band to 850 only, see whether it helps.
having the same issue here, but im quite sure its network related, inside my office the 3g dissapears at all and the same happends to a friend of mine who owns a SGS2 as well. whenever my outside the internet works as intended
also flashed trizillions of roms and modems before i gave up and blamed it on network rofl

H+/3g Delay

Im so pissed off at this phone. Supposed to be fast but my browsing experience sucks because of this delay between 3g/h+
Before I get flaimed I have read before, I tried fast dormancy off, I tried disabling H+ and putting 3g only but the same delay exists. I also tried putting the phone in wcdma mode so edge gets removed.
I don't know what to do, I came from an iphone 4 and although the pages load slower because of hardware I could actually see the data progress going and loading up, here my sgs2 just stands for 10 seconds doing nothing and then loads up the page fairly quick.
Sometimes it doesn't even load and says page could not be loaded even though I have the h+ icon on.
Now If anyone experiences this and has some sort of fix plz let me know.
Im running westcrip 9.6 with lph, and have had this issue in previous roms too.
My network is Claro Dominican republic
Thanks
I have a similar problem! In my case the phone suddenly switches from H to 3G, I don't know why, and then goes back to H. This happens while I'm using browser, generally when I activate data connection and I don't use anything, it remains on 3G
My problem is that sometimes the delay may be 2 seconds and its managable but then it can go up to 15 or not do anything at all.
Same problem, I thought it's ok, but if it's not, then how to manage your data, without any delays?
just in case for someone who might know how to fix your problem u should give them/us information about:
your rom
your kernel
your modem
rooted or not
ps. wrong section btw...

carrier and location (country) would be good too.
EDIT: whoops, saw it's in the first post. Sorry.
Its normal to go from G to H+ when data is in use. As soon as the phone detects that it needs to access the network, it will achieve the H+ connection. Apparently it will kill the battery if its always on H+. This, I understand. But the part I do not understand is the delay from G to H+. I am not sure if its a carrier issue for most of us, or the phone itself. I am assuming its a carrier issue though as it has happened on every ROM or Modem I have tried from personal experience. Not sure about the OP. It does seem to take some time at times to get from G to H+ - upwards of 15 seconds or more. Also, if it can't get H+, it will not browse at all on 3G

Yep, same problem in Moscow. It's probably related to device, nor to carrier. Kinda odd.

I don't think so. Seems to be a device issue. I just took a look at my Blackberry Bold 9900 I use for work and it always has H+. It doesn't go to 3G and then to H+ like the SGS2 does. And when I browse on that, its always ready to go, no delay. Not sure why our SGS2 needs to handshake H+ everytime
In my case it seems to depend upon the modem I use. kL1 works really well, however when I trialed ICS it was really slow as described.
Also, far less related, as for the mention of browsing, I use Dolphin and find that it seems to be much slower at either DNS lookups or redirects or something.
It's most likely because of your carriers settings. There's nothing you can do unless you call them questions about what their policy is at their end on data connectivity.

[Q] Rogers LTE Data connections drops sporadically

I've not seen this posted anywhere in the i717 part of the forms, and felt like it should be OK to post this.
Ever since I got my Galaxy Note from Rogers, I keep getting sporadic data connectivity issues. LTE data will work great, but if I set my phone down (such as when I am at work) and don't touch it for several hours, by the time I return the phone has no data connection.
However the status bar shows that I have full bars connected to LTE, yet when I open a browser or try to use the Play Store, it keeps saying I have no data connection.
This problem occurs on stock, and with custom roms, currently I am using the latest stable release of CM9 Quincyatt.
Has anyone else run into this problem (with Rogers or any other provider that offers LTE with the sgh-i717)? If so, is there anything I can do to mitigate this issue, currently the only fix I've is to simply reboot the phone. This seems to fix the problem, allowing me to access data until the next lengthy period of inactivity. Then of course after several hours of inactivity, when I go to use it again data will once again be dead (even though the phone reports I have a strong signal).
