I'm trying to keep my GPRS connection alive - all day
I'm using a mobile solution which relies on traffic being sent automatically via GPRS to a Qtek 2020i (service calls for field engineers)
The problem is that the GPRS appears to time out (or at least go to sleep) after a period of inactivity.
I need to keep the connection alive as having to manually reactivate it (or wake it up) defeats the object of my engineers receiving calls via GPRS.
The "G" symbol appears on a white background and has to be tapped to wake it up ("G" with left and right arrows).
Only then will the queued data be sent to the unit.
The timeout period appears to be around a couple of minutes.
I've checked the power settings - there is nothing which relates to GPRS timeout.
Any help would be much appreciated.
Would be worthwhile checking with your operator as I believe that the timeout is setup on the network not the device.
My understanding of the general issue is that the network times out the GPRS connection and the device or OS (WM2003 etc) does not properly handle reinitialising the connection or detecting that it has timed out.
Is the data really being sent to the device. We have used O2 and Orange and the IP allocated is not available from the internet unless you go with something like a VPN solution.
You could look at changing the app to request the info or at least ping a server every few minutes to keep the connection alive.
GB-Soft Tweak
There is a program called GB-Soft Tweak, which could help with the issue. I'm using it even on the MDA_PRO (as I did with the MDA2) and it's working flawlessly.
It has an option "to keep the GPRS connection always 'on'". I believe you can at least try it. It installs in "Settings" and once set, you don't need to touch anything.
It's just 13KB and I'll attach it to this message.

I will give it a try and thanks a lot man.
Hello everyone!
Just moved from a P3600 to the P4550 and noticed something strange twice in the last 4 days. When I looked at the display in the morning (phone and WLAN were off overnight.....hardly ever turn on WLAN, as I only use it when travelling) I found that WLAN had switched itself on sometime during the night. What gives?
Any ideas would be greatly appreciated!
Thanks!
This happens to me also if:
(1) ActiveSync is set to "as items arrive" (i.e. push)
(2) There is no phone signal.
Apparently AS looks for the Exchange server, and not being able to find a phone signal, turns on Wifi to see if it can connect like that.
I suppose this will also happen if you have AS set to poll mail at intervals. When the interval time arrives, I guess AS will want to go online and - not being able to use the phone signal - will turn on Wifi.
Very annoying as it drains the battery. It does NOT turn Wifi off after a while.
Oh well.

Oh - an afterthought: in CONNECTIONS I have set both programs accessing the net and programs accessing a private network configured to use MY WORK NETWORK. Don't know if fiddling around with that may stop AS turning on WifI.
Should you find a solution, please post coz I would like to fix this bug/feature too.
Hmmm.....if this theory is correct then going to flight-mode instead of just turning the phone off - should effectively not allow any kind of connections.....will check tomorrow....
I recently applied the Kaiser tweak to disable idle connections after 1 min - this works great when the phone is on, however, when it goes into sleep mode, this fails to work.
E.G. If I click send/receive on my emails then quickly put it into sleep, turn on the device in 10min and it would have stayed connected, once it is turned on after a minute it will disconnect.
This morning I turned on the device to see that it had connected to receive emails last night and had stayed connected for hours - of course once I turned it on the tweak kicked in and it disconnected after a minute.
So my question is, how do you get the tweak to work whilst in Sleep? Any work arounds?
Thanks in advance!
Hi
If you are referring to GPRS/3G there is no problem the connection remaining active. It isn't really active unless data is being transferred, it is just the session remains ready for data. The mobile operators prefer it working this way as it is less strain on the network creating a data connection and keeping it rather than setting them up/closing them down/setting them backup again.
It doesn't use any more power by remaining up.
The software isn't shutting down the connection when you have the phone in standby as quite simply the software will not be running in standby, everything stops in standby, so the program can't run to turn off the connection, until you turn the phone on again.

Phil
Hi Philip,
From my experience I have found that even if the data connection is open with no data flow (HSDPA / 3G ) it drains the battery much more than if it were closed.
Or is this just for HSDPA?

Hi
There is a blog that explains what is happening from Microsoft.
I would guess that while the connection is active something on the device is seeing that and stopping the device from entering standby.
The actual connection itself remaining open does not drain any more power as it isn't doing anything different than just having your phone on waiting for a call.

Hi Philip,
Thanks for your response.
I have to say though from the last few days of tinkering, an open connection does drain more than a closed one even with no data flowing. This is with HSDPA, I have not tested this with just a 3G open data connection though...
Are we talking about the same things? I'm a bit new to this phone though sorry.
Thanks,
I have recently procured an HTC Diamond mobile and is facing the following problem:
I have a Linksys Router at home. When I switch on the Wi-Fi in my Diamond, it gets connected to the router. In the status, I can see the signal strength, Tx, Rx rate etc. But when I open the browser (both opera & IE), the web pages does not open. Error message stating check the url or does any other programme using the internet works? appears. Even my weather does not get updated. Using the same router, I am able to connect my laptop as well as my desktop to Internet.
When my diamond is synced using active sync, my mobile is able to connect to the Internet & Weather application also get updated.
Kindly help me to resolve this issue and make diamond connect to net using wi-fi.
Thank you in advance.
I have the same problem sometimes
I just changed parameter in settings -> connections -> wireless lan -> power mode -> "best performance" instead of "best battery" and it seems to work now.
I'm new to WM, so I don't know if it's a bug: when I don't use my phone I press the power button, or I wait it to go to "sleep mode" in 40s.
When I press power button to reactivate the screen, I can see in the first seconds that the wlan was disconnected and connects again.
So it seems that wifi is always disconnected when the phone is in sleep mode? That means no mails can be received ? Can anyone confirm?
Thanks
Hi there for both of you!
I had a connection problem with my Diamond at home. It was almost the same as tkak just I couldn't figure out whether ActiveSync connects or not. I managed to bypass this to set my routers DHCP timeout from 1 week to 3 hours and it all went away. The network status showed periodic connect/reconnect during the problem so it might be a different prob than yours.

WM6 keeps WiFi connection asleep during sleep mode. Imagine the battery usage if it was connected to WiFi all the time. So be happy with that and beside it is usable. WiFi automatically tries to connect to the closest hot-spot if it was connected before each time you switch on. Normally it shouldn't take more than 5-10 seconds and the whole process can be followed on the top bar.
Mails: Use DirectPush and GPRS connection and e-mails will arrive instantly. Google for setting this up. With Wifi I dunno - if you schedule ActiveSync for a periodic check whether your WiFi will be used or a new GPRS connection. I think GPRS can be used while the device is asleep but I'm not sure. Someone should test this. Probably whichever is quicker to build up a connection will be used for data transfer. (Note: on some forum I read that if you disable GPRS auto check with a tweak battery will last longer so I guess this means that GPRS is always connected.
Regs, Cina.
Does your diamond obtain an IP adress from your router, and is the connection setup as 'connects to internet'?

Thank you for your answer,
I had a SE P1i before, and wifi was connected all the time with push mail. With the diamond and its weaker battery, I set up my mails schedule to connect every 15 min so wifi only needs to be active every 15min, even in sleep mode, I don't want it to be connected all the time this is of course a battery waste.
HSDPA is connecting in sleep mode there's no problem with that, I just wish to use wifi for mails when I'm at home as my data plan is unlimited for web surfing but only 10Mo/month for pop/imap connections.
BTW I don't use the "keylock" option, is it different from sleep mode in this case? I can't see the advantage of keylock versus sleep mode
I had an ETEN M600 for ages before and I found that for sync it always used GPRS even if WiFi was available. The cause for this was GPRS was available while device is asleep so it can start syncing immediately after wake up (does it needs to wake up for sync?). So you probably have to switch GPRS (HSDPA) off while you're at home.
Keylock is for locking hardware buttons and touchscreen while it is active. (You won't dial up anyone from your pocket). It has nothing to do with sleeping just if you set up the registry tweak the device get locked (Keylock software is started) if you press power to send it to sleep. (I've almost written "off" but it is obviously not true - you can switch it off with a long press on power = soft reset).
Hope this helped a bit.

Okay thank you, I checked and HSDPA is connecting every 15min in sleep mode even with wifi ON. If I switch data off I suppose nothing connects and no mail is received, which is I think it's a weird behaviour.
By the way, I have set my data connection to swich off 10 seconds after not being used, and it works perfectly and reconnects automatiquely when it needs to. But for the wifi I can find that option, it's stays connected all the time when I use the phone, even if I don't need to. Is it possible?
Maybe it's due to the fact that it's always checking if there are new networks? On Symbian UIQ3, you can pre-configure networks, give manually priorities for each networks (1.Wlan work, 2.Wlan home, 3.3G etc..) and for each application (web, mail, etc). When the phone connects it checks if the network "1" is available, if it's not it checks the network "2", and once it's connected it doesn't check anymore. Is there a WM6 advanced network tool like that?
(Sorry for my english)
I did the following and now it gets connected to the web:
I just changed parameter in settings -> connections -> wireless lan -> power mode -> "best performance" instead of "best battery".
I do not know why this needs to be done like this.
Thankyou all for resolving my problem
I'm experiencing problems connecting to my WL Router (DrayTek 2820n) using WiFi when the router is set to Auto instead of to a specific channel. I've noticed from some threads for other mobiles that people are exprience similar problems. Does anybody knows what is the story around which channels are supported on WiFi: 1-11, 1-12 or 1-13. My router is set to 13 by default. In addtion to that Diamond has problem to connect to some channels even in the 1-11 range. So how can I check, which channels are supported and for which region?
Edit: I did further testing and it became obvious that when using Auto channel selection on the router, Diamond wouldn't connect. When selecting manually any channel between 1-11 it works OK, but when selection channels 12-13 it stops working, which makes me believe that the Diamond doesn't have support for the channels for non-US regions.
Does anybody have any idea how to change wifi region to support 12-13 channels as well? So far I couldn't find anything on the net that would help me doing it. Is it possible that it might be WM 6.1 issue and not Diamond?
HI I am actually having a diffirent issue but still related to wi-fi. When my phone awakes from sleep, it promts me to connect to my wi-fi server at home, when it was already connected jus minutes before. I have to re-enter the pass phrase everytime it awakes from sleep. This does not seem normal as my 6.0 touch didnt do that.
Any takers on this?
For more channels, it depend of US version or EU version. You need to changer your firmware but the problem is that in France for Internet you use PPoA and Belgium PPoE and I do not know if in the US they use the same so you will probebly losse your ability to connect to the Internet. Having more channels is not interesting because you need a hope of 5 between channels ( ex : ch1 + 5 = ch 6 and ch6 + 5 = ch11) between ch1 and ch6 place a ch11 for avoiding interferances. In 802.11g that is a question of scheme.
Sorry for my poor English.
Problem connecting to home network wifi
Hi, i've been using diamond to connect to my wifi home network but since few days is not possible anymore even if nothing was changed in the settings of the router.
The phone recognize the network as available, i push connect, it comes connecting but instead of connecting to the netwok it goes back to available.
Password is correct and the setting are the same as few days ago.
Any idea which setting should be modified?
Thanks in advance!

Hello everyone,
I have one problem with my diamond. I disabled the "data transfer" with the improved comm manager. I usually use wifi when i'm home, however, i've seen that even though wifi is active, HSDPA connection is activated as well so i got charged, this sometimes happens when updating weather data or downloading emails.
Anyone with the same problem?
Yes - having he same problem.
I have WIFI at home and at work - so i want to use GPRS only when i am outside. never managed to do this - except when i kill GPRS fully - and even then Opera, the weather and push-mail wont work. :-(
WiFi Channels 12-13?
I need to bump up this issue again.
I can't find anywhere in this forum how would you change your WiFi channel range from US to EU (i.e. 1-11 to 1-13). My Diamond was purchased in Australia and I was hoping that the new SW upgrade would rectify that, but it looks to me that's not the case. Any idea if that can be done in registry?
Thanks.
Change Channel range from 1-11 to 1-13
***Bump***
Has anybody got any ideas how to increase the channel range from 1-11 to 1-13?
Hi, I am having a seperate problem from all that are listed. I have the linksys rangeplus router, and my Diamond wont even detect my network when it searches, yet my computer and PS3 do fine. Can anyone help me?
another problem...
Hi,
i have a problem with the wifi on my Diamond aswell..
I have a router at home which is encrypted. When I try to connect to it, I type the encryption key and it says Connected but i cant surf any pages. When i go back to wifi settings my home network switches between Not available and Connecting...
However, when i remove the encryption, everything seems to work fine. Since i dont want to treat my neighbors with free internet, does anyone have any tips for me?
(it is set to Best performance... +i'm sure i enter the right key...)
Thanx
The same over here... I found out, that some of cooked ROMs had this problem, but official worked. Before I couldn't connect via WPA2-PSK AES, all other encryptions worked. Until now... I tried to flash official ROM and RADIO, but it doesn't work anymore. I'm pretty sure it must be hardware problem. I need to send my Diamond to get fixed, but... The closest repair centre is in Prague (GSMobile)
!!!!!!!!!!!!!BUT BE AWARE!!!!!!!!!!!
I owned previously Qtek8310. After I send them my Qtek to replace the joystick, it came back with broken motherboard... This repeated 3 times and everytime they broke something else. I've got my Qtek8310 back as a total crap, destroyed and scratched... I called and send a claim to HTC Europe in London, but nothing happened since then. I don't believe them anymore. If you love your Diamond avoid to get it fixed in GSMobile!
Hi all. just got my Galaxy S and its a great phone.
One of the annoying part is that whenever the phone goes to standby mode, it connects to Edge network (E is displayed on top). It seems like whenever WI-FI is not available it always connect to Edge network.
Can I set it to connect to Edge network or WI-FI only when there is explicit request from the user?
yes 2G and 3G works even when the phone is in power saving mode for the push emails and other data syncs
WiFi only works when the phone is awake
but there is a fix for that some where in ths forum
Go to your Wi-Fi settings, open up the Menu->Advanced. Set sleep policy to never. Then you'll always have your wi-fi and the phone shouldn't need EDGE for data, unless you moved too far away from the access point.
Install "JuiceDefender" it will turn off net access when screen is off
