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.

Unreliable phone?

Hi All
I'm not able to make calls / receive calls properly. At least one call out of ten is not connecting at all.
I have tested my operator (SIM-card) and there is no quality issues. I live in city area and even though there is three signal bars on my phone, the Diamond is not able to connect.
Do you have same kind of difficulties to make or receive calls? I'm just wondering do I have lousy cell phone unit or is this common problem?
What is the latest radio sw version? Could it be the fix?
Best Regards,
Illodin

Try turning off 3g so it only uses grps\edge.
My p3600 used to "disconnect" from the network when 3G was enabled.
Not sure if this was a phone or operator bug.

This worked for me...
I had a problem similar to this when I first got my Diamond, literally the next day i was trying to make a call to my Voicemail and it wouldnt connect. I noticed that the signal strength was behaving very erratically. One sec it was 3 bars, then it was none, then the G symbol disappeared and then displayed a cross, then an H appeared, and this just kept on happening.
After reading XDA Developers and looking around the forum, I decided to turn of HSDPA so I no longer have my phone searching for the H. I have 3G and GPRS when needed and this does fine for me.
Just a workaround at the moment as im hoping that a new RADIO version will be released soon so I can turn this on again, but to be honest I dont really need it.
To turn off HSDPA, Goto START and then SETTINGS and then select the CONNECTION tab. Select the first icon, ADVANCED NETWORK and then untick the TURN ON HSDPA box.
I just find this works for me, and everythings fine now.
Hope this helps!

Hi Hallatore and Tomchap
Thank you for your info
I'll test the approuch you descriped. It's good to find that kind of solution.
But I think it is not good enough for me. I bought this device because the fast Internet connection. And without HSDPA it is not fast I think that the device with the price ticket +500€, should work better (parallel) with these features.
//Cheers,
Illodin

3G Connectivity

I have an Orange branded TyTn II, and it never connects up to 3G even though the area i live in is well covered by 3G.
It mostly stays on G. It has changed to E (EDGE) on occasions but thats it.
I am from the UK and live in the yorkshire area.
Anybody got any ideas, or do i need to speak to Orange?
Thanks

Did u check the band settings in settings/personal/phone?

I went into the settings and it says it is set to Auto.
So i would presume it would pick upthe best signal?

Yes, at least that is doing in my case.

If that is the case any other ideas as to what it could be, and why the phone does not detect 3G?
Thanks

Where are u from?
Go to commanager and check if there is 3g turned on.
Did u try to search this forum?

Check my first post for location.
In comm manager there is no option for 3G, the only other choice i can see is data connection, and i cannot turn this on.

The Connection button is only used to disconnect active data connections.
I ,along with some friends, have also been having problems with Orange's 3G the last few days (I just came back to the UK so I'm not sure how far back the problem started - my friends say its been like this for at least a week). Not sure if it is related though. Oh, I live in Essex.

U can install advanced config tool, and there under menu u can choose the layout of the commanager(there u can put the 3G button on the screen). But it could be the above mention reason.

My problem just got more complicated.
Have a look at this thread: http://forum.xda-developers.com/showthread.php?p=2606166

Hi alt236,
The strange thing is my unit has recently come back from repair, and the main board has been replaced, under warranty, because of a dodgy ROM flash, and the 3G still does not work.

Weird.
Have you tried with a different SIM card?

Ok, I just had a chat with Orange support. Thankfully I got a pretty helpful guy
Anyway, according to him, Orange does not fully support 3G yet (at least not officially) as only about 50% of their masts are 3G enabled. This means that they get network congestion problems causing devices not to connect or drop connections unexpectedly.
His advice was to try to connect at different times of the day, and to force the connection on the Kaiser (not to set it to auto).
As I live in an area with 4-5 3G masts immediately around me (yes, I know I will die from cancer ) its a bit weird for me to be unable to connect, but I'll give it another go, at a unsociable hour (4 in the morning for example) and see what happens then.
He did ask me if I wanted to get my phone tested though, so if it doesn't work tonight, I'll send it off and hope for the best.

Nice One alt236, that would explain the lack of 3G.
I will give it a go at different times of the day and see what happens.
Thnx

No luck with my overnight test.
I passed by an Orange shop in town this morning and I spoke with one of the staff members there.
He proposed that before I ship it out, I should call 156 which is technical support for data enquiries (MMS/WAP & WEB/Email) and PDA's as they can see what my phone is actually trying to do when connecting and push updated settings to it.
I've tried calling a couple of times today, but the queue is too long. I'll post back when I have news.

i have the exact same problem, please let me know what orange have to say!

XDA diamond - HSDPA connection

Hi all,
I've got the following problem with my XDA Diamond (O2 Germany).
- To establish a connection, first the 3G connection is enabled. After the 3G connection is up, it switches to HSDPA ("H" icon).
- Now everything works fine, no latencies and fine transfer speed.
- After a certain idle time (surfing...), the H disappears again and is exchanged by the 3G.
- When I try to download data again, it switches back to "H".
=> Then, huge latencies occur (up to 1 min. before data are received), the connection speed slows down dramatically or no more data is received at all.
I first thought of issues with my ROM (Bepe 0.99) or my RadioROM (.05). But after flashing to Aztor V7 and RadioROM .08, I'm afraid I have hardware troubles as the problem persists.
Now my questions: Did anybody here have the same problem? If yes, could you fix it? If yes, how? ;-)
Would be nice if you could help me. It would be really annoying to RMA the device...
Thanks for your help in advance!
Regards,
eypostel

That could be because you device disconnected from the net (thus it switched from H to 3G), and it take time for it to reconnect to the net.

Thanks for your hint, but I think this behaviour is not normal...
Even the connection cold start (establishing 3G connection, then switch to HSDPA) is faster and before, the connection was working fine:
When in 3G mode the connection was required, the icon changed to "H" within one second, and the data transfer started immediately.
Now, it takes about ~30 s before the first life sign, and then data reception is not even guaranteed.

eypostel

Thx prodigy7, this topic exactly describes my problem...

I have a question regarding this HSDPA idle bug. Turning off HSDPA should bring relief, but my MDA Compact IV does not have the HSDPA-switch. Can anybody have a look in their registry which values are changed when HSDPA is switched off on an XDA or HTC device?
It is easy, simply save a copy of the registry with PHM RegEditor before and after the change. Then compare both files with a file comparison editor (PSPad or TotalCommander for desktop PCs does the job).

This is so ridiculous... I have bought a HSDPA-device (Touch Pro) because I wanted to use HSDPA a lot... and it doesn't work at all... this was my first and last HTC device... I have invested 600€ for a piece of crap.

The Diamond does HSDPA just great, however your service provider must support it. In the UK T-Mobile supports it on their Web 'n' walk Plus and Max services. If you have normal web 'n' walk you can see the H and connect using HSDPA but its throttled.
Nothing to do with the device, just the service provider. It also depends on coverage. For example, when at home I get a H with 2 bars. When driving to work I loose that and get 3G and then eventually just G. Because my provider doesnt have HSDPA coverage where I work.
To turn HSDPA on and off easily use a cooked rom, i use Duttys. Very close to the original and tweaked just a little.

Did you read the german thread linked above? I guess not because what you wrote is wrong.
It is correct that the problem only exists if you use htc devices in the O2-HSDPA-Network. But: the problem only exists with HTC-devices in the O2-network. I am able to use any other (non-HTC) phone that supports HSDPA with the same sim-card successfully in the O2-network. And I am also able to surf using HSDPA with my HSPDA-Surfstick in the O2-HSDPA-Network. This means: the problem is not the network, it is the device (=HTC).

If it was that simple then none of us would be able to use HSDPA on our TD, but most of us can. I can use it on my TD on Orange in the UK and other networks including O2 when I am roaming in Europe and, for that matter South Africa (not sure about Germany). So the problems probably lies with the interaction between them, rather than solely the "fault" of one or other.

Seriously, sometimes people can be a bit absurd. 3G & HSDPA are standardized communication protocols. This means that there can be little (no?) device-to-device OR network-to-network variation with regards to the integral working of 3G. The context and application might vary and impact performance, though. For instance if a device is not supplying enough power to its 3G chip, signal acquisition might be slow and strength weak.

I highly doubt the existence of a bug limited to a single network and device brand. By the way the Qualcom chipsets (which incl. the 'radio chip') are not specific to HTC and many companies (incl. Kyocera, Motorola, Sharp, Sanyo, LG and Samsung) feature them. The specific Diamond Qualcomm chipset (MSM720xA) also features in the G1, Xperia, Motorola Atilla & Alexander, LG Incite and MANY others.

I seriously doubt that. To prove this, you would need to test EVERY single 3G phone that has ever existed with the network. Which is, quite frankly, impossible.
Like I mentioned earlier (ct. 1st paragraph) context and application might influence performance. Maybe you're just not in an area with sufficient coverage, maybe your specific device has a design flaw or malfunction. Whatever the problem is, I'm pretty damn sure that it's not "HTC-devices don't work on O2".

I use the german o2 internet pack L and I have the same problem. Seems to be an o2 issue.

That is a much more feasible scenario. Any other O2 users have this problem?

I totally agree with H3x. You say the problem is only HTC devices on O2 so therefore its a device problem. but surely as the problem only exists on O2 its an O2 problem? Every other network in the world seems to be fine. Did you test any other devices with your SIM and network or are you just reading whats on the internet and taking it as true. As we all know, the interwebs is never wrong.
But, your obviously not happy with your diamond so throw it away, go and buy a nokia.

Seems like the HTC-homies in this forum are not willing to read what I wrote before and keep asking the same stuff again and again. I mean, I wrote in the previous linked post all details that you are asking again here...
I'm outta here and will keep at the german forums where people are not constantly trying to convince me that I am stupid...

You're right of course. The bug mentioned here is not limited to a single brand nor a single network. But it seems to be limited to specific Qualcomm chipsets. According to numerous reports in German user boards all (?) devices using MSM7501A (HTC Touch Diamond, Touch Pro), MSM7200A (SE Xperia X1) and MSM7201A (HTC Touch HD) have trouble reconnecting from HSDPA-idle in German O2 network. Doing some research on the web I found similar reports from Swiss Orange users.
From my experience as a German O2 user: An idle HSDPA connection switches back from "H" to "3G" after 25 seconds. If you then send a new request, e.g. tapping a link in your browser, the connection indicator of your device changes to "H" again, but most of the time the connection hang up. You have to manually disconnect and reconnect... Switching off HSDPA/HSUPA gives you a stable 3G connect, however limited to basic 3G speed. Another workaround is to frequently ping around, a 10 to 15 second intervall does the job. With pushmail or some IM messenger active it may work, too.
That's my experience with the SE Xperia. And it's definitely not a local network issue nor temporary - I'm using a Palm Treo pro, too, without any problems at all. AFAIK the Palm also is a HTC device running on a Qualcomm chipset, the MSM7201 without an "A".

Orange Uk 3G not allowing calls and delayed txts anyone?

hi i have a touch diamond orange variety and when i travel to scarborough uk i dont get calls and will just get a txt 2hrs late saying missed call and i cant send msgs out.
ive tried my htc tytn 2 and thats the same and i tried my bros omnia and thats the same.
i was wondering if anyone else had same problem either in scarborough or anywhere else on orange uk?
ive tried numerous different radios etc
thanks for any help
rich

I'm on Orange in the UK and swapped to 3G as soon as I did I couldn't make any calls, turned out all my Phone settings were changed. On the services tab check Call Barring, Call Forwarding etc. I've gone back to my old sim only because the receiption for 3G was rubbish in my area. Hope you have better luck. tallen3

What do Orange have to say about it?

They blamed the phone, I managed to change the settings myself, Orange were less than helpful but probably about average for a phone company.

I was asking the OP!
But yes, unless you can actually see the mast with your naked eye 3G reception is a known issue with the Diamond. I have set mine to GSM only.

Orange 3G works fine for me without seeing the mast - even indoors. But that can't be the problem because if 3G reception is to weak or not available then it should revert to GPRS or Edge automatically and will still allow calls.
To the OP - is it all of Scarborough or just particular parts? Does it happen anywhere else in the UK?

The problem I have with 3G on my Orange Diamond is that although the phone just clings onto 3G indoors (about 1 mile from the nearest 3G mast) it drops down onto GSM as soon as I make a call - with associated momentary call interference - and drains the battery a lot quicker on standby (I'm syncing with Exchange every 15 mins 07:00-17:15 Mon-Fri).
If I'm 50 yards away from the mast I get HSDPA, which is handy when I'm in my car queueing at the tip, not...

hi i finally had a call from orange they now say its scarborough that doesnt have enough 3g masts and they have planning permission in for some more.
its strange everywhere else is fine even when i have lower 3g signal than scarborough.
they recommend i leave my handset on auto which doesnt work so was told everytime i go to scarborough manually turn phone to 2g.
not a perfect soloution, and i wonder why scarborough is like that? ever since they activated the hsdpa.
thanks for all the comments and suggestions.

If your phone won't auto switch between the two then it is faulty and Orange should sort it out shouldn't they? Or is it not their phone?

well it does switch between but i have a two bar 3g signal and it doesnt work for calls as explained and therefore wont switch to 2g.
thanks for all your help btw its not just my fone its most win mobile fones that my family and friends have.
