O2 Xda Stellar - wifi switches to GPRS when in standby

[Garyph77]

Hi - ive tried looking through the threads but cant find anything, so apologies if im repeating something all ready asked..

Ive been noticing on recent phone bills that im getting charged for gprs calls that i definatly havnt been making but my phone company insists that i have. After further investigating, ive seen that if im using wifi, and the phone turns to standby, when it switches back on gprs has been activated and is running underneath wifi.. and this is where (i think) my call charges have been coming from...( i hope that makes sense!)

Is this a common problem with the stellar/kaiser/tilt or just a problem with this individual unit - also, if it is a common problem is there anyway in which i can stop it happening?

I can understand where it is coming from.

When you go into standby (ie turn off the screen), the phone turns WiFi off to save battery. This makes sense, but imho WM is still too stupid to understand the concept of money. Result is that when it tries to continue doing whatever it was doing it will open a new connection and it's first choice is the GPRS/HSDPA connection.

As far as I am aware, the options to stop this from happening again are....

1) Stop WiFi from turning itself off when the phone goes into standby. I'd do this using KaiserTweak (http://forum.xda-developers.com/showthread.php?t=333898) - the Option is under "Data -> Wifi standby mode"

2) Disable the GPRS connections so it can't connect. One way is to remove the password so it asks before it connects. There's also a tool on here somewhere that allows you to quickly enable and disable connections.

Hope that helps.
