Dell notebook loses wireless lan on battery operation

[Guest]

I have a dell inspiron notebook and with Vista I have the problem that i lose
my wireless lan connection after a while (10-15 minutes) even when using the
connection. The network monitor then says " limited connectivity" for this
connection. Disconnecting and reconnecting manually solves it. It only
happens when I am running on battery.

In the bios there may be an option to disable the wireless lan when you are
running only on battery so as to conserve power. Check this out and see if it
is.
