Re: I need to monitor a dead network

Maybe, maybe not.

Typically I have had to do a stop(instead of a restart) then a
modprobe -r <networkmodulename> ; sleep 1 ; modprobe
<networkmodulename> ; then restart.

That works unless the NIC itself has a serious firmware issue and
locks up and really needs a hardware reset that comes on a complete
reboot.
