EXEC dropping GPRS data connection when on the move - JASJAR, XDA Exec, MDA Pro General

Hi,
I've recently put the JasJar 1.30.76 ROM on my O2 EXEC with its radio version 1.09.00.
Everything's great except I'm seeing the GPRS data connection drop and cease to reconnect when I'm on the move. This really upsets apps like TomTom traffic downloads! The only way to resolve the issue is a soft reset. I've just tried fixing the band to GSM to see if it helps.
Has anyone else seen this issue? Is it radio version related?
Thanks.

QTEK9100 and GPRS/EDGE - AAARGGHH!!!!

For some reason - my QTEK 9100 fails to maintain the connection to my GPRS service. Once I connect, it holds the connection until I make/receive a phone call. Thereafter, the device shows the connection in place, but it fails to pass any more data through the connection. To keep using the data connection, I must either soft reset or switch flight mode on/off.
(Needless to say, I have been able to use my SIM in other GPRS-enabled phones).
ROM 1.1.7.5
Date 9/22/05
Radio 01.01.10
Protocol 4.0.13.16
ExtRom 1.1.7.105
Anyone have any ideas?
Is there a ROM upgrade or RegEdit that could do the trick?
Same **** with mine 9100 on MTS. We should get together to solve this issue. Let me know if you got the solution. My ICQ 2662731, phone no. 916 137 7540, Leonid.
Absolutely the same problem with my Qtek 9100 on MTS. Some people on the forums say it's operator's problem; others claim it's not. However, switching from MTS is not an option for me anyway (corporate cell phone number, etc.) so I would be very much obliged for any solutions, or at least hints towards what can be causing it.
One possible solution (haven't tested myself yet) is setting GPRS to 'always on' via the registry editor; however
a) Will it drain my battery much more than usual?
b) Won't GPRS get disconnected in standby mode?
hi
hi. try to initiate GPRS connection with the default inbox email. press send and receive to check email. let it connect GPRS. when someone call u. it still maitain but the during call, the other person must pick up the phone. if nobody pick up the phone. the GPRS will have problem and need to turon and turnoff radio again. this is the only to maintain gprs, that is, to initiate GPRS connection with the default inbox email.

One thing I know for sure:
it will not drain your battery any more that when connecting gprs on demand. I used to use the "grps always on" feature and can't tell the difference in battery life.
Regardless of the "gprs always on" setting I do sometimes have problems with the connection. The icons (gprs) say it's on but no data is transferred (no e-mail/www received) but it happens very rarely and I can't tell in what circumstances.
By the way: holding the red off-hook key for 5 secs closes the gprs connection - check if it doesn't make your problem easier to bare ;-)
Maybe you could try another operator's SIM - at leat you'd know if it's the Wizard or the operator.

Yes, I know about this one; however, since GPRS won't reconnect anyway, this doesn't solve anything for me.
Oh well, I'll keep experimenting and hopefully Qtek will release some ROM updates in the future to deal with the problem.
Update: After playing with the settings a bit, the problem indeed seems to be with phone calls; i.e. I can disconnect/reconnect GPRS manually without any problems, but once a phone call is made or received, GPRS stops reconnecting. I have a suspicion it's actually an operator issue but haven't had time to try some other SIM yet.

I called service today about this problem, they heard nothing about it, they said. Also they invited to flash rom, that was released month ago, they said. I asked them about version but call operator didn't know.
I'm afraid to do that because they could flash older verison than I have, and there are some roms that have troubles with incoming calls, I read in russian Qtek forum.
My version:
OS: 1.3.9.4 RUS
Date: 9/29/05
Radio: 01.01.10
Protocol: 4.0.13.16
ExtROM: 1.1.7.105
I read there are some utilities to save rom but I cannot find how to save rom to hard disk to restore it in future surely.
My version is:
ROM 1.1.7.9
Date 9/16/05
Radio 01.04.10
Protocol 4.0.13.17
ExtRom 1.1.7.111
(Russian OS)
Just read on some Russian forums that there were the same problems with s100 until the new radio version was released, so I guess we just have to wait.

Just tried it myself, didn't work for me either.
So far, the problem can be diagnosed as: regardless of GPRS status, a phone call (outbound or received) will screw up the existing GPRS connection and any future attempts to reconnect unless a soft reset/flight mode switch is made.
I hope to god a ROM update will be available in the near future; meanwhile, any and all suggestions are welcome.
Today I visited service, they flashed me the same rom I already had. Then they tried to solve problem at least 2 hours but with no success.
I advised them to be ready for crowd of users of 9100 who connect to MTS.
Technician said I have to wait new rom update, but he cannot say nothing about release date.
I want to beleave...
Some guy at Russian forums put forth an idea that our problem might in fact be an issue with lousy MTS implementation of EDGE.
So in theory it could be solved by turning EDGE off entirely (if it is indeed possible).
Same problem on my Qtek 9100 ... is there any updates available for the ROM?
I have this same problem on both my Kjam and Qtek 9100. I am in the United States and use Cingular. I suspect this is not a carrier problem.
I'm in the US on Cingular with a Qtek 9100. I think the issue is that the carrier drops the GPRS connection after time, or the signal is lost and WM5 doesn't react. Either way, seems like leaving GPRS in constant ON mode plays into the problem rather than help it. After installing GB-SOFT Tweak http://msmobiles.com/news.php/4714.html and setting it to release GPRS if unused for more than 10 or 15 minutes, I don't get the GPRS problem nearly as often. Furthermore, when a GPRS lockup does occur, turning flight mode on and then off again restores function without the long cycle time of a soft reset

I had the same problem on my IMate and it was fixed by turning off (2sec) and then turning on your device once the GPRS connection was established. Haven't tested on my jam yet
I have the same problem since upgrading to AKU2 ROM - before I never had that issue...

JasJar only works in WCDMA mode

I have my JJ since October 2005. It worked 100% on the original ROM. Early Dec. 2005 I upgraded to the then latest Radio and ROM's. No issues.
Then suddenly From January I cannot get the Phone to work or connect to a data connection. I was told to upgrade to a 64Bit SIM which I did but still no result. I have installed every release of the Radio ROM and every ROM version compatible on the Uni up to date.
When the BAND is set to Auto it will not give me a data connection nor will the phone work. When in GSM same result. When I put the BAND in WCDMA it works 100%. Data connections work, Phone works, SMS etc. Problem is it only works in 3G areas now!
HELP, after 2 months I'm pulling out my hear and carrying my SP3i as backup.
Bump
@postman
what other applications are you using? Have you tried to start a fresh system with no third part apps (ie after a hard reset)? Have you tried to use the .cab files from i-mate for your network?
When I had a JJ I had frequent connections/disconnectiond between GPRS and UMTS. With the latest Radio on my XDA Exec I don't suffer from such frequent switching and it seems to have improved the batetry life as well. I used radio rom version 1.06.00.
J,
At the moment with the new ROM no apps installed appart from the ExtROM. Local network .cab also installed.
Problem is not as such that swtiching is taking place, problem is in BAND = Auto or GSM the Uni does not work for neither phone service nor data. When in WCDMA it works 100% without any issues. Like I said the prob. with this is that 3G is not covered like GSM, so if I leave work the phone feature is basically null and void as only GPRS/GSM/EDGE in area where I live.
Maybe the 3G and GSM/GPRS works off diff stacks / protocols or even hardware?
Yours desperate,
postmanpat
@postman, if you have tried to reflash your JJ and still the problem persists and the original problem did not occur because you added any third-party s/w then my conclusion is that you may have a hardware problem. Contact i-mate they usually reply within 2/3 days.
I would say you probably have a hardware problem !!, the GSM and UMTS aspects of the phone are very separate !!!

Orange Swiss GPRS

Update 20060509
If I go on Phone/Options/Network and press Find Network then it finds GPRS signal again and works for some time.
Does anybody know whether there is a way to create a shortcut to it?
Thanks!
______________________
Sorry for posting a "local" subject but can't find answers elsewhere.
I upgraded to:
ROM 2.17.7.2 WWE
Radio version 02.07.10
Before being Orange i could test with another provider and everything worked fine.
After being Orange, i get GPRS signal and later i loose it, being always in the same place, just as time goes by. If i reset, hence reconnect, then GPRS signal and phone signals are great.
Battery is always at good level and it happens while charging too.
I thought was an Orange problem, but signal is very good immediately after reset.
Did anybody experience same problem and found a reason or a solution, apart from leaving Orange?
Thanks!
Orange disconnects automatically users from the GPRS network since about 18 months. This is because their systems are outdated and can not cope with the demand.

T-Mobile UK - GPRS/3G session reconnecting problems

last few days i've been experiencing very strange problem using w'n'w service on T-Mobile UK. let's say i'm connected, i can browse web, check mail, etc. when i close (or i loose, i.e. in the Tube) GPRS/3G session and then try to reconnect, my Vario II is popping out error balloon 'The answering modem has disconnected. ...' straight away *every time*. only thing which solves the matter is switching off and back on again Phone module (just like switching off/on mobile phone). same thing happens when i connect both in 'Auto' and 'GSM-only' modes.
i surely didn't change anything with connection settings lately. it also used to work without any problems a week ago or so, and i thought it's network-related problem. i wrote a complain to customer service, but lady called me back and suggested doing a hard-reset, which obviously i'd like to avoid. :/
do anyone here also experiencing that problem on T-Mobile UK network (particularly in London)?
I had exactly the same problem with my mda vario I. I had to go in and out of flight mode which then allowed me to reconnect.
Recently I've had to do a hard reset and now it works perfectly.
There was a post which said something about deleting the settings in network management my memory is a little hazy though. A search on this site should bring it up
I'm currently experiencing the same thing on my Vodafone PDA 1605 with an Orange SIM. I get the exact same error message ballon every time I disconnect from GPRS. It's happened to me ever since I've had the unit, which is only about a month now. I've tried to find a fix for it on here but have come up empty.
Let me know if you find anything else out!
problem's solved! the reason was a defective BatteryStatus today plug-in - i'm using beta version of it, which had some bug preventing data sessions from reconnecting. i have now installed newest version, which has that bug fixed and my connection are working fine now!
thx for all for suggestions.
well... I have no answer to Your question... but... pozdrawiam z Bedford..
a vario II to swietny wybor
peace

Network Loss

Hi,
I've got an M3100 flashed to the SA Tytn ROM and after recently it seems to have had problems staying on a network. When I start it up it finds the network and connects for a while but then looses it (the exclamation mark next to the signal indicator) and refuses to find it again. The only way to get it to connect is to go into phone settings and tell it to refresh the network.
Any ideas as to what could be causing this?
Many thanks!
I was having a similar problem with my new Jasjam (HT 647xxx).
The factory installed ROM had a radio version 1.21.31.10 and the rom date was 8th september 2006.
Quite strangely the latest ROM available on the i-mate site is dated 21st July 2006 and has a radio version 1.07.03.10.
Since I have downgraded to the ROM available on the i-mate site it seems my problems are over. Maybe the ROM you have installed has a faulty radio rom.
Regards
Well I've got 1.18.00.10 as my radio version and I've had it for a while without any problems.
Just a couple of very routine things to be sure of (perhaps before going into Radio versions etc)
1. That the device is set to best performance not best battery under the network settings
2. The range is not great for wifi 10-15 metres at best so just to be sure your in good range. I know when I'm on the periphery of signal it connects fine but drops signal fairly often.
Cheers
Mike
Sorry, I should have made it clear that the problem is with the cellular network.
Sorry to bump this, but has anyone got any ideas? A full reflash of the device doesn't seem to have done anything so I'm beginning to worry that this is a hardware problem...
