Ah good, which wireless card are you using?

Are you sure?  I've had this kind of behaviour under two
circumstances:
1) autologout is active on the machine you're logging in to.   
This will log you out after a certain amount of time if tere's no
input.  It's usually an hour.
set autologout 1440
will make it a day I think.
2) the dhcp  server is cutting you off.  I had one router  do this to
me very frequently indeed if it thought i wasn't paying it enough
attention, kind of like a spoilt child.   
Doing something like
ping -i 60 your-target-machine &
seemed to do the trick there.  
Of course I've not used wireless so there might be no end of other
explanations.
cheers
