[maemo-users] Connection up, no ping to 770 after a while

[From: Damien Challet]

Dear All,

My 770 has a weird (software) problem: after idling for a while, its 
connection enters into a weird state whereby it is shown as up in the status 
bar, but I cannot ping the device. When using the network again, there is a 
delay before packets flow again, as if the device was reauthenticating itself 
again. This is with os2007he

This does not happen in Mer, for instance, therefore I suspect that it is 
linked to some power saving settings, but which one?

Thanks for any help.

Damien
