What's the make and model# of the motherboard?  If you don't know that, 
post the make and model# of the machine itself.  It's possible that the 
BIOS is trying to do power management on its own, which could cause 
this problem.  Or if the machine's APM implementation isn't up to par, 
things could get weird.  Try unloading the apm module or booting with 
"linux apm=off".

To stop the connection at 9pm and then restart it at 6am, just do:

at 21:00
/etc/init.d/network stop
^D
at 6:00
/etc/init.d/network start
^D
