Problem with internet Communication

Hello All,
I have a problem with my kaiser, it started i think 2 weeks ago. I have vodafone (netherlands) with a data connection account (hsdpa). Now is the problem that i can't use umts (3g) or hspda. The only thing i can use is gprs. It looks like the modem or something is broken. But that is a kind of weird because (if i understand correctly) its al the same chip (wifi and so on). When i open internet explorer it begins to connect a gprs, 3g data connection. But it can't connect, than you can see a X by the synchronisation arrows (on the top of the screen). And after a few secconds it comes with a message that with the current settings there can't be a data connection. But if seen other messages as well ( the modem on the other side disconnected the connection) The weird thing is that i tried my sim card in my friends kaiser there it works fine, so it have to be my kaiser.
Ok what i tried:
I have a dutch htc kaiser (not vodafone branded or anything)
I use the latest dutty rom, but i tried the orriginal rom and different roms to see if the problem was the rom or something.
When i let the 3g mode on i can see that the phone finds a 3g connection (to call over umts).
Is there any program or tool or something so i can test the modem?
Or does anyone know a sollution for me, i will be very greatfull!!

Ok i tried a other radio to, maybe this was the problem. But it didn't, at this moment i have the default htc dutch rom (who was on the phone when i got it). I searched the net for the same problems, what i found was that this error could be happening when you have your wifi connection open, but i have wifi disabled. The phone is still receiving a 3G connection, but after a few secconds the 3G icon is gone and the failed synchronisation icon (two arrows with an X) is visible. than you can see that the phone is reconnecting. and then if i want to connect to the internet the same story as above is happening.
When i search internet i couldn't find an tool to test the chip/modem.
Because i have it spl unlocked i can't return it for rma, is it posible to restore the default spl?

Hi,
unfortunately I have the same problem with my Kaiser. I have an unbranded German version and it worked fine with all bands (GPRS, EDGE, UMTS(3G) and HSDPA) but since two weeks ago its only working with GPRS and EDGE mode. I have to change band-selection from AUTO to GSM in order to make or receive any calls.
I didn't do any ROM flashing, everything remains the same as the device was shipped.
I assume, that something is damaged but I have no idea how it could happen or how I can find out exactly what is causing the problem.
Since there is still warranty I'll return my Kaiser soon.

seems to be a widening problem
hi,
it seems many have the same issue, see my other posts for linkage to some other threads on it...no solution yet as far as I can tell.
rich
p.s. moderators any chance to link these threads and make a sticky?

ok, thanks for your reply. I've allready found another thread for that issue. But im still uncertain if its a bug in my device or a combination of a bug with a provider specific (Tmob Germany) problem or if its only the provider to blame for??
Chris

I have a slightly different problem. I don't have 3G in my area but only EDGE. Now the problem is that I cannot get speeds higher than about 80 kbs with EDGE.
Now when I put the same SIM in my Touch I can get speeds upto 200 kbs. So obviously this is not a problem of my service provider but rather something wrong with the device.
I have repeated the trial by swapping SIMs a number of times but with similar results all the time. Really don't know of a solution. Will appreciate any help.

haven't seen the edge problem
hi,
my edge speeds seem to vary more by location...I measure up to 200+kbs but have seen it go much lower too. there is a location where I can still get 3G working and i measured up to 1.7mbs for downloading! At my home location it is sporadic edge only and I can't even always get to speakeasy.com to test it, sometimes the speedtest says its not licensed..switching to wifi and it works. My guess is some needed ports are getting blocked by at&t at times..because sometimes it works. I brought all this up with at&t..they are taking some charges off this month and switched me to a cheaper plan too...so they at least seem to care even if they can't quite fix things yet.

my Kaiser do not work with 3G only works on GSM

Suddenly it had happened; NO 3G nor GPRS data transmission. I can see the 3G sign , but when I make calls the phone disconnects; when somebody call me, he received a message that my phone is off line. Only when 3G signal is on. But when normal GSM is on, everything will be OK. My phone can not get data from the internet, even though it shows that is is connected. I tried all of the above solutions to fix this problem but no helpand sometimes it shows 3g sign but as soon as i try to call some1 all the signals are gone.. I tried to hard reset and try it before installing any software, no help. I tried mostly all available ROMs and Radio ROMs; even the original, but not fixed. I do not what to do. Now, I am using the phone with GSM only, NO 3G. Please help!!!

Hi there nunu,
I had the same problem, went back to the store and nope not a known problem.... So I started to troubleshoot this
1. normal G connection
2. 3G appears or even H
3. signal lost and after 30 sec. the cycle starts again.
what worked for me was the changing the of the radio version. I am currently in the Netherlands and here the NEON_Radinly_1.65.24.36 works fine, I confirmed it by loading a rom with a different radio in it and the result was again the same.
hope this helped in any way...
Let me (us) know.

life is good, but life get's much better with a Kaiser

are you trying to connect with [email protected] / cingular1 ?
this is the kinda information you should have put in your first post
I use the above and have zero problems in Philadelphia

My 3G went out for like a day here (Phone only worked on Edge), then it started working again. Cellular carriers do have outages from time to time. Has it been a long while since it stopped working?

Flash to a different compatible radio. If you do not get 3G/H service back, then you have a hardware issue with your radio, and will need to have the phone serviced.

what newtwork are you on?
have you tried your sim in a different handset?
what happens when running in gsm only mode?
in settings phone network change selection to manual and tap find networks and reselect network (this is known as a manual roam) does this make a difference?

Same here!, im in montreal, canada with Rogers, and in 3g doesnt work, it detects the 3G network, but as soon as i try to make a call or go on the internet it looses the signal and i have to go on GSM mode.
and i'm using LKDV12 but i still had the same problem on AT&T Original rom, and Dual V2.
Anyone?

Major problem --
I have been travelling round the world for a year and have the same problem, Have tried many radios, if I use 3G( wscdma) or auto band then the signal drops everytime i try to make a call, and no data is possible however if I use gsm only data and voice work fine, thease symptoms are on many networks, Chile, Easter Island,Tahiti, NZ, Fiji, Optus ( OZ ), and m1 ( singapore ),
Radios tried
EMO 1.71.09.01
Neon 1.65.24.36
1.65.21.18 ( att )
I even loaded the generic dopod rom + radio and it didnt seem to help.
Is it possible something low level has changed whilst doing all this flashing ?
Or could the Hard SPL affect something.
I always try to buy a 3G USIM in each country and test the sim in a backup G800 to ensure the carrier has enabled 3g data okay.
Phone is Kaiser ( HTC TytnII )
ROM is varied but and usually lorentis series roms -- L26 12 light atm
Symptoms, 3G icon shows but data wont connect, if you try to call radio strength bar drops to zero and cell communications are lost , sometimes reestablishes comms but often needs soft reset to band switch to work.
If 3G icon not showing all calls and GPRS data works Okay.
Personally I would not expect this to be a hardware failiure as many others are experiencing teh same fault and for working hardware to fail in use is more erratic in the failiure mode, but a low level register, or some other type of protocol corruption could easiliy be the cause......
The proven "high GPS current consumption in standby" issue is also present as it seems to be on all Kaisers but afaik the root cause of this was never resolved either .....

my Kaiser do not work with 3G only works on GSM NEED HELP
HI I´m from mexico telcel gsm band and the same problm works on my kaiser tried changing the rom put the htc rom again the radio too

i have the same problem did you make it work how you set a gsm band instead of the 3g on the phone tks for your assis
dr.vogel

I have the same problem. Already had it with WM6.0 original HTC ROM (Finnish ROM, but language set to English). Then sent it to service. It came back, they said they "reapplied software or smth" and it worked after that. Then after 6.1 update again, the same problem (even with the latest updated Radio ROM).
When I set band selection to auto, it picks up 3G or even H but tends to loose it and definetly looses connection to network if I try to make a call. Can't take any incoming calls either.
It works ok when I force it to use GSM (EDGE for data) on Band selection tab, in phone properties.
I probably won't bother taking it to service anymore cause there is no local service here in Estonia, they ship it to Finland and it will take a minimum of 3 weeks...
... so I'm waiting for Xperia X1 and hope it's not as much HTC.

Read this: http://forum.xda-developers.com/showthread.php?t=335074
Hardware problem, repair needed and unavoidable to get 3G functionality back.

I have the same problem.
I bought an O2 Stellar (Kaiser) from a work colleague and it worked fine on 3G/Auto on the day I bought it.
The next morning, when I switched on the phone, it had exactly the symptoms described (i.e. it would only work if forced into GSM mode).
My colleague took it back to O2 under warranty.
1 week later, it was returned as 'fixed', but it actually still had the problem, so my colleague returned it again to O2.
Another week later, O2 provided a replacement unit under warranty.
The replacement worked fine, until the next morning when I turned on the phone and had to force it into GSM mode again because it wouldn't work in 3G/Auto mode.
I'm on 3 in the UK and I suspect the problem is something to do with the roaming onto Orange GSM which happens when there is no 3G signal from 3UK. However, on the day each of the units worked, it was switching between 3G and GSM repeatedly because the 3G signal is fairly poor in my office.
I'm now waiting for my colleague to return from his holiday so that he can return this unit to O2 and we'll see if we get another replacement. If we do, I'm very reluctant to actually use it - I think I'll probably just sell it on and get something different. Shame because I really like the Kaiser.

as mentioned before, another thing that you should've tried is to call the helpline and see if there's an outage in your area. I've been experiencing the same problem in a very particular area (3G hand-off to EDGE problem only happens on campus). Tried different radios and problem still exist, so I gave them a call today and turned out that there is an outage here.

In my case, it's not caused by a network outage - 3G works fine on my Hermes in the same locations.
Good thought though.

Relax boys...I have'd the same problem... The only solution is to go with your phone for warranty return. There they will change your TyTN II mother board and all will be ok. IT IS THE ONLY WAY.
PS do the same thing I did http://forum.xda-developers.com/showthread.php?t=418375

i post this thead and the solution
i post this tread an the solution came on tha answer of various of you great ideas i get the solution changing the rom and the wm to 6.1 and the rom is the dutty's it has worked almost perfectly in any wy itested only some install on the gps progrms but no mayor problem tks all you friens for a great support

The same thing has happened to me as well (Orange UK).
Initially I thought that it was an outage in my area as my friends had problems connecting to 3G as well, but their problem has been fixed but I still cannot.
I'll be contacting their tech support dept. later today and I'll post back.

Help

My city just got 3g yesterday and I am having a big problem. I cannot connect
to the network at all when 3g is turned on. Shows 3g is connected..but I can't make any calls, or get on the web or even text message. After a min or so, it shows I am not connected to anything then it will do it all again. If I turn on only use 2g, I have no problems and I connect with Edge. I have 3 other friends who have g1's, one is rooted liked myself and no one has any problems. Any Ideas? I was originally using dwang 1.14 rom, but changed to cyanogen 4.2.8.1 and it doesn't make a difference.

i had a problem like urs when 3g was first introduced in my city..the problem was just the area i was in and the young 3g network.. 3g worked other place but not around my house, eventhough i got reception.. so i suggest, first try the 3g somewhere closer to downtown or something and see if problem still presists.

Yea, I tried that. I was at work with the three other guys who have a g1 and they all had no problem with 3g. But, me on the other hand just couldn't connect for anything. It would show connected to 3g, but I couldn't place a call..send a text or get on the web...that after a few seconds would show no service at all...strange.

I just tried reinstalling the radio, but still didn't fix it.

it might be the sim i had the same problem they just gave me a new one at the tmobile store

Ok, got a different sim card and I am having the same problem. Any other ideas.

contact your carrier say 3g is not registering to your phone, and the may tell you how to set the network back up.. my friend had the same problem with his rooted g1, he called tmobile they said its not set right.. all he said his phone came with special optional capabilites.. and the tellar said.. "can you do that to my phone"

try putting ur sim in another g1 i dunno if you have to register it or not though and see if you can make calls that way with 3g it might be just some setting on the phone or something

[Q] Milestone is loosing signal - hardware or software error?

Yesterday my Milestone dropped the network and wrote "Only emergency calls". On other phones there was maximum signal. After a while the phone logged in to the network, but lost the signal again. I thought something is with the ROM, so I made a factory reset but didn't help. I flashed the correct SBF file (first Éclair, then Froyo), but didn't help. I restored an earlier MOD I used without any problem but didn't work.
I always used the German baseband files with other MODs because my Milestone is German.
The problem is that if I make anything (I mean anything related to the data connection), the GSM signal disappears, sometimes data connection remain with no problem, sometimes it is lost, too, but sometimes it has GSM signal with only EDGE network. If I do nothing, just turn off the screen and do nothing, everything goes back to normal, and the phone has normal data connection with GSM signal, I can make or receive phone calls.
I put in another SIM but the issue was the same.
Can I try something related to software and didn't try yet or this is a hardware failure? And if so, what is the price of a GSM module? I couldn't find it.
MOD: It seems that only the 3G is not working (sometimes HSPA does while 3G phone connection don't), with 2G there isn't any problem.

dial *#*#4636#*#*
Under phone info, try a different network type.
It probably defaults to GSM (auto). It does on mine anyway and it's fine.
But maybe WCDMA preferred, GSM only, or WCDMA only will work better.
It depends on which is screwing up... the WCDMA or the GSM
edit: had the dialpad code wrong... again.. geez

Are you sure you have applied the correct baseband?
I would tell to re-apply thru AOR.
Sent from my Milestone using XDA Premium App

You could go to settings, wireless and networks and somewhere there there is use only 2g networks and if that is checked, you could try to uncheck it. That is what happened to me before on the froyo mod. Also, you could try turning on airplane mode, then turn it off. Good luck

I always used the German baseband, tried to switch 2G/3G many times, applied the baseband trough OR, applied the RTEU baseband, re-flashed the ROM, the original Éclair, the Froyo, again and again but nothing helped. I gave up I decided to go to the service. Before that on a forum somebody asked something, I gave an answer but I was not 100% sure about it, so I flashed the RTEU Froyo.
And it worked. The 3G, HSPA, 2G, EDGE, phone functions all are working now. My phone is truly German, it has QWERTZ keyboard and the original ROM was the ROM from Deutsche Vodafone (tried that one before, too), it has the logo on its box, and the German baseband files always worked. I don't know what just happened, it's simply working now. Why now... don't know.

[Q] 3g problems nexus one

hello every body
i have this problem with my nexus one when i am connected to 3g service (umts,hsdpa,Etc'). i can't make calls or receive any calls, i can't use the internet (data) or get sms and Etc'. but i have full bars reception. when i check the vi in setting to "use only 2g" the phone work great.
i tried everything downgrade/upgrade roms,radios. i tried to go back to my first backup and even do PASSIMG but nothing help i googled it every where but nothing
please some one can help???
without 3g the smartphone is useless
thanks,
shushkis

What network you on? I would at least see how old the sim card is.
Lots of time if you have an older sim card it just can't handle a newer system.

I am connected through Orange IL
and i tried switching sims even with other networks.
and more the phone worked fine at the beginning it just happened i remember i switch to one of CY roms and it happened

Have you tried a full wipe and reinstall the rom?

yes of course i tried customized roms and stock roms but nothing helped

I would check your apn settings...

apn connected to taking or getting calls?
i thought it's just for internet connection

Its just a guess.
If its a problem on multiple ROMs, its likely to be either hardware or settings. Settings are cheaper and easier to test, and that's the only setting I can think of...?
Of course, doing a full wipe (including system), installing a new ROM, and testing before you restore any apps and settings may be another way to test, but since the apn settings are pre-baked into most ROMs, it wouldn't rule our the apn...?

OK I tried to put apn settings and it didnt help
you say hardware?
but when I check in settings "use only 2g" the transceiver works great .
maybe the nexus have two transceiver one for 2g and one for 3g?
seems un-logical

No there are two radios one for 3g and one for 2g because 2g is for calls and 3g for data but when 3G is unavailable the phone will use the 2g for the data.

The Same Trouble
shushkis,
I have the same trouble, my 3G connection works so bad, but if I use only 2g connection, all works good... I have no idea what happend with my N1. I have a N1 for 3G 850 (AT&T) model.
Thanks for advantage.

So maybe the problem is the hardware? if the N1 have two inidvidul transcivers?

I have also the same problem. I've tried many different roms and radios. I use 900/2100 3G. What's strang is that 3G works perfectly at home, but when moving to another tower I get emergency calls only warning. 2g works fine.

I just started having 3G issues at home. With 3G on the phone reboots like once an hour, but on 2G I've gone days without a reboot. My 3G signal is not the best at home, but I don't know why that would make the phone reboot. I'm on T-Mo USA.

The one I'm using is only a couple months old, and it works well in my Desire HD, and my Moto Defy. It's only the N1, but I guess maybe it could be that. I'll look into more.

If it's only a few months old, then it may nor be the SIM that is the problem. I suggested it because a number of T-Mo users were having similar problems after a recent network upgrade, and a new SIM seems to fix the issue for most...
