people with GPRS problems...

I am one of those users that is having trouble connecting to GPRS more than once and getting the "unknown reason" problem. Only a soft reset or turn on/off flight mode will fix it. Well I found out what is causing this, at least for my device. I am running Wisbar Advance on mine and is what causing the problem. Once I closed the app, I can connect/disconnect GPRS as I please. I made calls in between also and it still works...
The developer for Wisbar is working on this issue so hopefully he will get this fixed. In the meantime, I have turned off Wisbar..
Hope this is what causing u guys' devices also.

Great info! Just a heads up. I had this problem since I upgraded to the 1.06 ROM however I have never installed Wizbar Advance. The only thing that I could get to fix it was upgrading to the Norwegian 1.11 ROM version or using the 1.10 US Radio stack. Even the Finish 1.11 did not fix the problem.

I have the problem and I'm not using Wisbar. I guess magician_os1.11wwe_bigstorage_6.zip is based on the Finnish ROM?

You can add another application to the list of problem apps (at least this worked for me)
Sygic .mobile contacts seems to mess up GPRS as well.
I've been using the 1.06 WWE rom, and i tried anasky's 1.11 bigstorage rom, and both times, with .mobile contacts installed, i received the "cannot connect for an unknown reason" error, after uninstalling it, GPRS reconnects fine everytime.
Hope this helps some of you.

i changed my sim card to a new one and now i don't get that error. plus i believe that part of that error is the service provider.
hope that helps

I have Qtek 1.11 and same problem too
It is a real pain, I do not have Wisbar, and I can only connect once then need a reset. Any ideas out there?

One cheap solution is to put the phone in flight mode and then go back to reset the GPRS. Not very smooth, but at least better than having to soft reset.

I have tried to turn flight modem on/off but i still get the error
"dialed:isplnk1.swip.net. The answering modem has disconnected. To check your connection settings and change them if needed, tap settings"
Does ne1 know what I can do? so I can use my gprs again. it worked fine just a day ago, and I havent done anythin at all that could cause this problem

I don' t have a magician but a blue angel.
I've got the same problem.
It's the last built of IA Caller ID.
I've make a hard reset with no IA Caller and no problem again.

just double check the settings to make sure that the access point name shows up in the number section of the connection settings, when its not there that can cause the answering modem problems

I have 2 SIM Cards with the same number, one for the QTek 2020, and one for a Motorola mpx200.
If they are both switched on, then my GPRS is disconnected after about 15 minutes, and I can only reconnect by going in and out of flight mode.
If I switch the Motorola off, then I stay connected, and can disconnect
and reconnect properly.

Never had that error message. Only the one hamsup1o was talking about. Is the Norwegian 1.11 Ananskyfied yet? I want to test if the problem is fixed in that one.

For me, I don't think it's any one piece of software. Since I upgraded my Jam last weekend to 1.11, it continually disconnects from GPRS. Soft resets may or may not correct the problem on the first try so a second reset is in order. Trying to turn Flight Mode On/Off is a chore in itself. I may need to tap "Turn Flight Mode On" several times before it finally does it. Even when GPRS is connected it will only last 5 minutes. Then while still connected, going to a different webpage, says that webpage cannot be found. Very freakin' frustrating!! :evil:
So, today at work I backed everything to SD and did a Hard Reset. I then cancelled out of the Operator settings, but allowed the other apps to install and soft reset. I manually added my data settings and connected. Within two minutes I lost my connection. Reset the device and couldn't connect. Reset again and it's fine. It's hit or miss. Restored from backup. Gave a MS Voice Command error so deleted that. Several resets later on the train ride home and it's been fine ever since, for now!
The question is, could this be a T-Mobile problem? I called them yesterday and all they could tell me is that data outages in the Boston area may occur in the evenings due to upgrades. Perhaps it's just a coincidence that I did the ROM upgrade and TMo is acting up. I'm pulling hairs here!!

I have the exact same problem with my Jam on T-Mobile (in Colorado) however it seems to have gotten better with the 1.11 ROM. The strange thing is that it does not ever happen with my 6315 on T-Mobile. I have spoken with their customer services serveral times and we have tried a few different things. The last thing we tried was a brand new SIM card to remove that as a posible problem. Since doing that, I can stay connected to GPRS, take calls and it re-connects with out me doing anything and it seems to have helped.
I have not tried to see if there is any change between wap.voicestream.com or internet2.voicestream.com. Which are you using?

I have the same problem with GPRS and the Cannot connect for an unknown reason. It initially connects fine, but if I disconnect it manually, I cannot reconnect without the soft reset. I started getting this error when I upgraded to 1.11WWE last night. I went back to Version 1.06WWE and the problem was gone so it is defiantely a ROM problem. Imate's Customer "Dis"-Service continues to timeout everytime I go online with them. I am in the process of trying the UK 1.11JAM Rom to see if that makes any difference. I am with T-Mobile USA.
On the Club I-mate forum there are people with this problem as well and one of them is on Cingular!!! So it's not carrier specific.
__________edit
I tried the UK 1.11 ROM and it worked a bit better. There was even a new tab in the GPRS bubble that you could click to disconnect the GPRS rather than holding down the red phone button. But alas, I still got the Cannot Connect for an unknown reason mesage. I'm going back to 1.06 (Thankfully I backed it up) It worked fine. Is anyone having this problem with the Anansky hacked ROM?
Also, why does the UK version come with Skype and the WWE version doesn't?

Could it be due to Activesync?
I too have the GPRS problem, usually it occurs after synchronizing with the PC. The flight mode trick fixes it. I can repeat this behavior and can always fix it, so it remains a nuisance...
Since you can access the internet through Activesync, maybe the OS stays locked in that mode and does not allow for GPRS to be a valid network connection...
Anybody else have similar symptoms?

Mashie, I use internet3.voicestream.com. As you said nothing seems to help.
chinadan, Yes! I had the exact same thing happen to me last night. I've been tinkering with my Jam for the last week trying to get it to work. Last night it was working fine, but then I connected it to my desktop to load PHM Registry and when I disconnected, GPRS started flaking out! Performing a soft reset didn't help.
I've been going back and forth with i-Mate CS, and it's obvious they know there's an issue. They seem to be getting a little testie since I'm basically telling them I'm not an idiot so please get the crap fixed! They had the nerve to send me instructions on how to setup a GPRS Connection on the Jam! :twisted: What nerve!
Anyway, think I'll try loading the worldwide 1.11WWE and see what happens. Anyone have a backup of 1.06 US 850 ROM?
Thanks and cheers!

Well, I went almost 24 hours without a GPRS problem on my JAM yesterday. I didn't get the usual "Cannot connect for an unknown reason" error message. This time I got a message saying that there was a problem with the modem???? I don't know where that one came from... changed my gprs setting to internet2.voicestream.com and it works now....until the next error message.
Screw it. I'm going back to 1.06. The JAM is VERY sluggish now and I can't even get it into flight mode to correct the problem. I guess I'll wait for the patch. (It seemslike we spend most of our time waiting for a patch or an update of some kind. ARGGGHH!)
ALso, I don't know if this was the case with the 1.06 ROM, but I used to have to hold down the red phone button for a few seconds to get the GPRS to disconnect. But with the 1.11UK rom all it takes is for you to click the red phone button and the connection is dropped. Example: If I'm on the Today Screen with GPRS connected, click the red phone button and voila, gprs is disconnected. Is this normal? I don't remember it disconnecting so easily with 1.06.

Any chance you give us a link to those pics? Pleaseeeeeeee :twisted:

Ok, been tinkering around this evening concerning the GPRS connection issues and this is what I have thus far. First, Club IMate has new Operator Settings on their website. One of their techs was kind enough to e-mail it to me this afternoon and checking their website this evening shows T-Mobile ver1.6. Applied those settings and it seemed to do a better job at installing my VPN settings for internet3.voicestream.com. However, when I checked the Connections screen it listed My Isp with my VPN connection and My Work Network was setup for wap.voicestream.com. Ok, nice but I don't use the wap settings. Connecting through IE to wap.yahoo.com resulted in the TMo Wap connection to launch, but not my VPN connection. So I went back into Connection settings and set both Work and Internet to "My ISP". Upon doing this and selecting any website from IE, it wouldn't connect and give me the error "Make sure you have your modem installed blah, blah, blah". If I then press and held on the "G" and tapped connect, it connected just fine.
So that got me thinking about the Registry again and why in the Connection screen for both Internet and Private network, why there was no option for "The Internet", or "My Secure WAP" so forth and so on. When I had my XDA IIs, those where options. So I loaded PHM Registry to the device and went exploring. The first thing I found and deleted was in: \HKLM\Software\HTC\WModem. I deleted the Preset GPRS key. The next thing I found where all the Interent settings I just mentioned in:
\HKLM\Software\Microsoft\ConnMgr\Destinations\. There is listed "The Interent" (which I tried to create myself in Connections but it said it already existed) and My Secure Wap plus others that I had made. So for starters I deleted "The Internet" key and reset the device.
Went back into Connections and created a new network called The Internet and added my connection to internet3. I then switched it to only look at The Internet network. Launching IE again and trying to go to wap.yahoo.com. Again, I get the "Unable to Connect: Ensure that your modems are presentand inserted correctly, and no network card present".
So obvioulsy, my edits to the Registry made little difference. So again that got me thinking. Why would their be a WAP connection when I selected T-Mobile VPN during the new cab installation? Because it needs it!
I then went back into the Network Management screen under connections and left it set to The Internet for programs that auto connect to the internet and set it to My Work Network for the private network option. Since doing this I've had no issues when any connection while browsing. If I go to a WAP site it automatically connects to T-Mobile WAP connection. If I then decide to go to a full blown HTTP website, it automatically stops the WAP connection and launches the VPN one. There is no delay when it does this, well, maybe a second! :lol:
My thinking is (and, I'm no programmer or Registry master!) that the problem lies in the Registry settings for IE. Perhaps it runs deeper than that but if one of you Guru's could take a look perhaps we can get this ironed out once and for all. Thanks for listening!

Wifi to GPRS/3G

I have searched this and other forums and have not seen either this problem or an answer to it. Per AT&T's suggestion, I just upgraded to the new AT&T rom version that adds PTT and seems to have big problems. My current issue is that when I first boot up and connect via GPRS/3G all works well. When I get to a wifi area and switch to wifi, again all works well. However when I leave the wifi area (or just turn off wifi) I can't get any data via GPRS/3G. The balloon comes up saying it is connecting. The little "G" and bidirectional arrows in the top left indicate it is connected. However in the browser, it just continues to grind away with "Locating" in the bottom right corner until it finally times out and puts up a screen that says that the "page cannot be displayed because the connection was lost". I open the connection manager and press and hold the "Data Connection" icon until that goes off and try again, same problem. The only way I can get GPRS/3G data connection to actually work again is to reboot. Any ideas what is going on or how this can be fixed? Forgot to add that this is an HTC 8525. Thanks.

From your description I wasn't able determine whether AT&T's suggestion was aimed at remedying the issue, or if it's something that came about with the update.
Assuming the latter, you may want to try a hard reset first and run it for a bit before loading any other apps. Failing that, reflash the ROM. I had a lot of trouble with my radio when my 8525 was new, but it mysteriously cleared up after a few radio flashes.

Thanks but still a problem
Thanks for your thoughts here. I hard reset and reflashed.
Yes the firmware is the latest one that AT&T has suggested that everyone who had the older Cingular phones upgrade to. It provides the AT&T logo, the "push to talk" feature, and some other junk. I have contacted AT&T about this and their response was to send me a new phone that they claimed had the old firmware, since they have been getting a lot of complaints about the new firmware. It didn't have the old firmware and also it's SIM card reader appears to be broken. I called HTC and they said that they too have had lots of complaints about the new firmware quirks but had nothing to offer to solve them. Anyway, the old firmware had no problem switching between wifi and CGRS so I don't think it is in the hardware. On the other hand I'm surprised that nobody else is encountering the problem from the upgrade.

I'm having the same prob. Purchase three of these phones and the other users have little technical expertise. First I set up a sync with my office PC. Then loaded the ROM update. I run MAC's @ home had difficulty connecting to my home wifi. Finally determined that the 8525 would not accept the 13 key ASCII wep password. Needed to use the HEX. So I connected. Went to work and had problems syncing with my PC. Active sync had to rediscover the device. Now I'm back home and can't connect again. My Device ID changed names upon "resyncing" and I updated the Airport Base Station with my new name. I've spent a lot of time on this issue.. Maybe I need to send em back for an iPhone!

Well I found a solution to it
This is a great forum - though somewhat hard to search through thoroughly. Anyway the solution for me was to go back to ROM 1.34. Found how to do that through flashing from the micro card at http://forum.xda-developers.com/showthread.php?t=311704&highlight=cingular+8525+rom+version and getting the production ROM version at http://wiki.xda-developers.com/index.php?pagename=Hermes_Upgrades. Back to normal - everything works fine. Just for a trial, I also downloaded ROM V2.1.1 and it works find also - but sure seems a bit large - ends up with 42.9M of storage free vs V1.34 that has 50.25. Think I'll try the the memory expansion process at http://forum.xda-developers.com/showthread.php?t=298327&highlight=want+more+storage. That seems to at least provide a more than 9 megabyte smaller MBH file but I don't know what that translates to in memory usage yet.
Suspect there is a way to fix this problem but I haven't seen anything in the forums on it.

Elf loses phone signal, doesn't reconnect

My wife's Elf keeps losing the phone network connection, each time she was in an area without reception, like elevators etc. and than refuses to register back to the network. Only way to get it to register again is to do a soft reset. (turning off and on the phone radio sometimes works, automatic and manual network selection don't). Tried another SIM card, same thing happened. The problem developed when she started to use GPRS/EDGE (previosly used her phone for calls and SMS).
Any ideas?

Have you tried flashing to a new radio in the elf upgrading forums?
Cheers

Changed radio still no go. Interesting enough it works when she doesn't use GPRS. I changed the RIL registry settings, and will be testing it next few days.

Oh, check it out and see how it goes.
Radio is usually affecting the issue.
You can hard reset, if it doesnt work!
Do backup!!

Seems like I tried everything possible and still nothing, it is probably hardware failure. My wife is going nokia after this, she said no more winmo.

HD2 Web Connectivity Issues and Analysis

Seriously people....
I've seen lots of threads recently. People are complaining that the HD2's data connection cuts out, leaving them unable to access the Internet from their phones for who knows how long. I know, it IS kinda annoying...But the thing is..
I can tell you this IS NOT a hardware problem. It's something to do with either the OS....or something in the phone's registry settings which no one has picked up yet...I hear that phones like the TP2 do not have this error, and I agree. My old unbranded Touch Pro 2 was brilliant, I could use it for IM and texts anywhere...LOL I used to sit on the Bus while people stared at my phone, while I was on Messenger talking to my phone. Anyways, here's what I wanna tell you guys. Hope I help out everyone in some way or another.
What I have:
HD2
3 Mobile Sim-So yeah, My Operator is 3 UK
Living in London, UK
Using ENERGY's 17th March Version ROM
HUSPA, HDSPA Enabled
What I've noticed:
The phone cuts out the signal when the transition between 3G and H occurs in the icons. As a result, the Internet cuts out temporarily, and programs such as Messenger lose connectivity for a while. For example, when the icon is on H, and no one's talking on Messenger, the Icon changes back to 3G....during this moment it cuts out sometimes..until it reverts back to the H icon (Got that? I know, it's a little long and complicated when I word it like that, but read it out and it'll make sense xD)
Now, whenever I have the phone connected to my PC/Laptop (Either as a Wi Fi Router or through the cable and then using Internet Sharing, either way, the phone does NOT change back to 3G, it stays constantly on H (Mind you, I usually download during this period). Anyways, the point being that the connection is VERY stable and constant, when in this state, connected to my PC/Laptop and the device is accessing the Internet through my phone's Data Connection. So what do you all think? And what have YOU found out? Leave your responses and ideas below

Some things I have found out are, if you Enable ONLY HUSPA in the Settings/Connectivity options, the connections seem to be more stable. Furthermore, if you really want to, Disable Advanced Connections, stay only on 3G, and enjoy a LOT of stability (At the cost of slower speed surfing and downloading )

My HD2 does not connect at all anymore. I called in to support because I completely lost data connectivity (web browser, email, slacker, whatever - no connection). They verified no troubles on their end. I moved the sim to my old touch pro (running Energy ROM w/ winmo 6.5 and Sense 2.1) and that phone connects fine. So it's not the SIM, and it's not the network.
I've also done a hard reset to get back to stock and still have the problem, which tells me that it's not a registry / software setting.
They only thing that leaves is faulty hardware - or firmware that a ROM hard reset wouldn't affect. Either way I need to replace the device altogether.
Unfortunately, tmo is out of stock and so I can only wait for a more to become available before it can be replaced.

Which phone company are you with? I experienced the same problem with 3UK in North London for a couple of months up until the beginning of last week but it was a problem at 3's end, not mine. Other people have been experiencing similar issues with non-3 phones in London (http://www.3g.co.uk/3GForum/showthread.php?t=102192).

yes, I had problems in London too before Good Friday. Especially on Tues+Wed.
Others around me inthe library also had similar issues with their iphones. I kept on switching the baseband and modes, and reapplying my 3G settings to keep it alive and solve the outages.
Most people with issues were on vodafone or O2 (like me).
It would work, then cut, then work.
I thought at first it was because I had a custom ROM, but iphone users had the same - and lots of timeouts on requests.
I DO believe however that running ROMS like energy's and Dutty's HG 1.7 with 2.10 (which I'm currently running) bases as 2_08 radios is not great for the uk and exacerbates the connection issue. 2_07 is better...and in any event we SHOULD be using 1.72 based roms with 2_09 radio.
I have also noticed that on COM5 23544 builds the opera mobile 9.7 and 10 google boxes do not work. They come up as failed connection, but then i click on teh link and it works...weird huh???
So I think last week was because of network faults in London. But in general, these 2.10 based ROMS and their radios are not ideal for stability.
I had perfect call and HSDPA stability with 1.48stock+2_09 radio.
Having turned to a 23544 rom (Dutty's HG) with 2_08 radio I've had much less call and internet stability (and quality) over the stock with 2_09.

HD2 no signal, shows exclamation

Hi everyone, my HD2 just stopped working with no signal at all.and shows a exclamation all the time, sim cards are no problem. i've updated the phone with official sw, still have this problem at the beginning.

has the phone been blacklisted?
is the phone turned on in wireless mode in settings? ( ya never no)
is it still under warranty?

My HD2 has done the exact same thing, just shows an !
it doesnt even try to find a signal.
phone was a tmobile UK version, which was unlocked to use any network.
the problem has literly just happened today.
have tried different offical roms, and different sim cards.

Just phoned my provider in regards to my phone, quoted the emei and have been told the phone is blacklisted.
they are sending a request to have it unbarred. will post the outcome.

I have had this happen alot with Vodaphone UK. This is a brand new number so doubt it has been black listed.
I can get this working my turning the phone to airplane mode then back to phone mode, this most of the time makes the phone look for a signal.
Usually happens to me when there is no signal like in a tunnel, the phone does not seem to try looking for the network until you force it to.

This is possibly a fault with the timeout of the HTC HD2. Could be once it tries to connect when out of signal the device gives up after a number of attemtps.
Does anyone know?t

I was searching before posting for just this problem.
It is really irritating me. The phone can jump from deciding there is no signal to sometimes even going to full-bar "H"!
I hav currently resorted to turning off 3G as at least that way I am eliminating the idiocy of it prefering 0/1 bar of "H" vs near full non-3G reception for calls.
Even so at times it will just sit there for ages having dropped a signal with the exclamation showing and then jump back to life [in the same place] with good reception.
I am also on Voda UK

Mine has done that twice, in 4 months. 1 time phone was turned off inside connections, no idea how? 2nd time I just shut off, & back on, signal was back, hasn't happened in months now?

so does anyone have a solution to this problem?
I've checked with my service provider and my phone is not blacklisted...
My SIM card seems fine and everything else seems fine, except it keeps giving me the exclamation mark.. most of the time i notice it's when i get out of the lift (but that could be because that's when i usually check my phone before I put it on my desk).
There are many occasions (probably 5+ times/day) where I turn my phone on (ie, off standby) after it's been sitting on my desk for an hour or so to check calls, etc and there is that dreaded exclamation mark.
I know the area around my desk does have a signal because the guy next to me on the same network has a strong 3G and 2G signal.
Sometimes going to Comms to turn airplane mode on and off to force it to look for a signal works, but sometimes it doesnt.
I've tried soft-resetting, hard-resetting, using different radios, different ROMs, etc and still no good.
Funny thing is, it's only been happening over the past 2-3 weeks.. and I'm not sure what triggered it.
It's really starting to frustrate the crap outta me and friends have been asking why they can't get through...
Any help would be appreciated.. . I'm trying to avoid sending it to the HTC service centre if I can because they're slooooow and the stories I've read about my local centre are pretty bad (when I had my HTC diamond).

Solved:upgrade your rom everything gonna b in place

Upgrade to what?

I am having the same problem, for a hile now. Been fiddling with phone settings parameters, trying to see the effect. One particular combination so far seems to work. Try this: Comm manager --> Phone --> Tap Change Phone settings --> Menu --> Advanced network --> GPRS --> select CHAP authentication --> then CSD Line Type --> select Data rate 9600(v.110). Then OK, Back, and Done with the Comm manager. Observe if the network pickup performance (switching from non-existent H or 3G to E or G) works better for you after that. It does better for me, so far.

I'm having the same problem - NO SIGNAL
Any solution?

i recently discovered that for my problem, it was to do with the earphones. Not sure why, but it only seems to happen to me not long after i plug or unplug the earphones.
I usually have my HD2 on my desk with the music going while I work, but every hour or so, I unplug the earphones and take my phone by itself out with me for a cigarette.. then I come back and plug the earphones back in.
Often when I'm about to head downstairs, I turn on the screen while the music is still going and i see the "!"... as soon as I unplug the earphones, the bars indicating reception comes back straightaway!
Not sure if it's a coincidence or whether it really does have something to do with the earphone/earphone jack.

Since I upgraded to the Vodafone rom on the htc website I have not had this problem

Since I upgraded to the Vodafone rom on the htc website I have not had this problem
Click to expand...
Click to collapse
I have just bitten the bullet and accepted the phone is crap at swithing between 2G and 3G signal so turn off 3G in a couple of locations when I know I get this problem [home - I can use WIFI] and my office.
HTC would not be drawn at all on un updated Radio and this problem being "fixed" in USA ROMs

Fixed
the very easy fix is to do this :
settings _ personal _ phone _ network then make network selection to manual ,, then choose ur provider,,, then u will have signal,, after that u can turn it back to automatic
100% working

Thanks a "fix" not a solution.
Rather silly to have to jump through hoops to make a mobile phone recognise available reception

Have the same problem
I have the same problem now, any solution for that?
