Stale GPRS during connection - Windows Mobile Software Development

We have a repeatable GPRS Connection issue on the XDA. I would be interested to know is any person can suggest a solution, and whether any body else has found the same problem.
Whilst connecting on the move, between radio masts, the GPRS sometimes becomes stale.
The connection will timeout after some long period, or when the calling application kills the attempt. After this, every other attempt to connect will have the same result. After a hard-reset, the device will connect in a few seconds without issue as expected.
The odd part, is by examining a 'feature' of the signal stength meter (which always return 69% when connected to GPRS) it appears that the connection has been made in all cases, but the RAS server seems to think the connection is still being made. -- It seems obvious that some part of the RAS with GRPS has become stuck in some stale state to which only a reboot will fix it.
A single timeout can of course be countered by another attempt to connect. But when every subsequest attempt leads to failure, some other solution is needed.
If anybody can suggest a solution to this, I would be extreamly interested.
Thanks, Ben Clewett.

BA Dropping GPRS?

(Posted this in the thread for the T-Mobile ROM, but realized it might be better to post it in its own thread.)
After upgrading to the latest BA ROM (the T-Mobile one), I have some GPRS problems. Namely, if the screen goes off, GPRS drops.
I know the device is capable of keeping GPRS connection with the screen off, because under the previous (O2) image, it had no trouble. I am getting better Bluetooth performance under this image (whether through actual fixes to the stack or just dumb blind luck), so I would prefer not to revert if possible.
(I'm also seeing it periodically drop the USB connection while cradled, but haven't figured out any common cause. This is annoying but not nearly so much so as the GPRS problem.)
Is anyone else experiencing any issue like this? For what it's worth, my actual device is branded as an O2 Xda IIs.
This is your solution
Hello:
A great guy solved this... It owrked for me... I changed the AP name to internet as he said and worked!

Data Connection keeps disconnecting

Hi, maybe someone can help, i have already tried two different ROMS from this site and my Data connection keeps disconnecting right away after it retrieves something.
For example, once i connect to retreieve email it disconnects, then if i try opening my browser go to google.com and leave it inactive just for a few seconds it disconnects. basically every application i open or close keeps disconnecting me. once connected i am fine, but has anyone else run into this?
I have tried all the different CAB settings for MEdianet
I have a Cingular 8525
I tried Vanilla as well as LVSW Roms, i just would like my data connection to remain on. I am not looking for a tweak which constantly forces it on (unless thats a last resort), i just would like it to behave as it did on WM5
Any help would be really appreciated
Thank you

the tweak you search for is in the Phone Section of HTweakC... enable always on of a certain connection... and yes it is a last resort... as the OS closes inactivity connections... now the timeout can be changed of course but that requires registry changes under HKLM\Comm\ConnMgr
Connection stays on!
Hi!
Maybe you can help me.
I upgraded my WM5 to WM6.
Now my problem is, if the mobil connect to gprs (automatically,for mail download,...), it doesn`t disconnecting after receiving and stays on line! I tried the settings for the mail account. But nothing helps. The best would, if the data connection disable after same minutes. Save the Bat.
You have a solution for me?
Thx

GPRS/3G Connection troubles

Hi all!
I know this has been discussed before, but it has never really been answered or a *working* solution been found to this problem:
I have the Cingular 8525 and my WAN connection (yes, no matter if it's Edge, 3G or HSDPA and no matter if I use isp.cingular or wap.cingular) just seems to die off after the PDA has been sitting for a while in STANDBY.
After seeing how incredibly stable and reliable all the blackberrys work, I still opted for the PDA because I liked the versatility plus the ADVERTISED push capabilities of it.
Apart from non-working tools like "gprs keepalive" etc, how can anyone REALLY PREVENT programs that are running from being stopped? Is there a Reg-Hack for this?
Here's my setup. Fresh blank WM VI Black 2.0 (great imags jas !!) and ONLY VGSMail (for mailpush) and IM+ for yahoo messenger installed. Rest absolutely untouched. Everything works fine as long as the thing is actually ON (display lit up and everything). Once i either wait for the timeout or manually put it in standby by pressing the power button, the Yahoo IM+ will react for another 5 minutes, but VGSmail almost immediately goes deaf. I have a TCP bridge in front of my IMAP server so I can see all in/out traffic to the IMAP by just accepting connections on port 1430 and routing all traffic to 143 while dumping it into a log. I can see the PDA connect the server and go into IDLE. Every time a new message arrives, the PDA is SUPPOSED to get it, but it just doesn't when it's in standby. Completely defeats the whole purpose of it.
Long story short:
HOW do you prevent the connection/radio/windows/software from "silently falling asleep" when the connection should stay open and new messages (email via VGS or IMs via IM+) should be received?
P.s. I already used the included HTweakC to acticate autoconnect and permanent connect. opens up the connection fine after reboot, but that's it!
THIS HAPPENS WITH EVERY IMAGE I HAVE TRIED! Original Cingular, Cingular Hacked AKU3.3, Black 1.2 and Black 2.0 :-((
Thanks
Ive had the same issues, my internet connection will just randomly quit on me. One second it will be working the next it will disconnect. Seems to be when I bring it out of standby or get a call. Definitely not as stable as WM5 was.
Radio Version?
Which radio version are you running? I have two things different with my configuration, but I had similar issues with my service (T-Mo USA).
My GPRS connection would hang, even when on the charger (not sleeping).
Turns out a radio update caused the behavior to quit altogether. I could drive completely across town, and have 10-15 new emails in my box, whereas before, I had to either press/hold the disconnect button, or soft reset.
My current versions are in my signature.
Hope this helps.

Yeah, I had radio 1.27.00.00 before, now I have 1.38.30.10
Also I do have newest Hard-SPL 1.40 installed. So I'm pretty much cutting edge here. Howewer, the PROBLEM has been annoying me since WM2003SE.
Is it just the way it is with desktops? Micky Mouse Soft dominates the market, releases one pile of **** after another, never really fixing bugs but introducing new ones by the thousands and we users (who in this case have paid $500 for the device) are left in the dust?
If I just imagine delivering buggy crap like this to MY customers, they would kill me!
Anyone have some good ideas or hacks? I definitely need to get this working at least to a somewhat acceptable level. Since having the Hermes with the first "original" WM5 on it, I got used to rebooting that unreliable Micro$hit every morning when I get up, to make it usually just about last for the day. I'm definitely not willing to reboot every hour !!!
I have this problem
I have this problem however I still receive push email. the most annoying thing is that I cannot keep a data session active with a voice call.
I am on Orange UK network. I use 4smartphone's hosted exchange service. I get directpush working 24/7 with Black 2.0 OS. I also receive my pop email whilst on voicecalls.
So its not a WM6 issue. Its either your network or your connection settings.
I must say that it actually improved a lot since installing Black 2.0. However, the connection still silently dies off eventually. I now have a makeshift solution using FlexMail, set to poll emails every 15 min. So what happens is as long as the PDA is ON, I get immediate PUSH mail. Once I put it in standby, it continues to work for a minute or two, then the connection ****s up. Every 15 min Flexmail wakes up and polls for emails, which most of the times seems to work as I can see in my logfile that every 15 min the tcp connection opens up and the server dumps all new mails over to the phone. It then enters IDLE and at some point dies away with "recv(): connection timed out".
So it's all pretty messy still and I'm wondering what you can do to PREVENT the line from silently dying in the first place. Tried tools like GPRS Keepalive with no luck, since the whole program stops being executed in standby and hence it can not keep the connection up = useless. I need some hack/tool/program that stays active during standby! Then I could just have it ping my mailserver once per minute to keep the connection open.
Any ideas would be greatly appreciated

GPRS Connection Never Log off after close Browser

Guys,
I notice that when I close the Opera browser, the GPRS is still connected on the background and I don't have such problem with my previous Xperia.
Anyone can tell me any solution to this issue?
I left it on the whole time never disconnected it, unless if the connections failed...
It will not take much of the battery, unless you uses it
I also have this problem on the device....I have an internet flatrate, so costs isn't the problem, but not everybody has a flatrate so it should be fixed.
I wanted to try out the new PUSH-INTERNET option on the phone and it works great, it downloads the webpage content every few hours but it doesnt disconnect automatically after that, so sometimes I look at the phone and find out that the GPRS hast been on for an hour or so,it also happens after I sync the weather on the manila, on the TP it syncs and automatically disconnects, but on the TP2 it just stays connected and I have to disconnect manually which is annoying..........does anyone know how I can fix this??
thx!
This works on mine!
This worked on my artemis and now on the TP2

Galaxy Tab Pro 8,4'' [SM-T320] - WLAN flapping issue

Hey guys,
FIrst of all: Thanks for maybe helping me.
So my problem is that I have a really annoying WiFi issue with my Galaxy Tab Pro. I installed a cm13 build (Link in that style because I am not allowed to share links...)
Code:
download[B]DOT[/B]cyanogenmod[B]DOT[/B]org/?device=mondrianwifi
a month ago and have one big problem with it. Whenever I want to use WLAN to connect to the internet (or use it on my local network, whatever) it just keeps flapping. It turns on and off and on and off and so on. I thought that it would be related to my home network at first (so that it doesn't get a IP or something like that), but after I checked my DHCP and general network settings and came to the conclusion that it can't be related to that. All other devices in my network are able to get a IP (and go online). When I turn on the WiFi on the tablet and check the network settings I see that it gets a IP but looses it after 1-2 secs. The thing which makes absolute no sense to me is that after a while (turning WiFi off and on again, 3-4 times) it often is able to get and keep a IP address. After that everything works fine - often for 1-2 hours until it looses the IP again and I have to begin with the game of randomness. I checked in the known bugs and could not finde that issue listet there. So I think it is maybe not related to the cm13 build I am using..? Or not even to the device? I don't know. Maybe you can help me - would be helpful enough if someone could tell me which logs I have to check when having a WiFi issue. I am quite new to such problems and don't know how I should start the troubleshooting.
So thanks in advance and greetings,
Maik
