Powering up Interface


My laptop has two interfaces, eth0, 1gbit LAN, and eth1 which is wireless. I usually use eth1 for day-to-day computing, but sometimes I need to transfer large files quickly, so I sometimes switch from eth1 to eth0. The problem I am experiencing is that as my laptop boots, it checks to see if there is a cable plugged into eth0, and if it doesn't find one, it powers the port off, meaning I cannot plug a cable in later without restarting.

Does anyone know how to power the interface up after my laptop has booted?

If you make sure to load the module for your ethernet card, it should stay powered up regardless of a cable being plugged in. Are you using gentoo on your laptop? I have gentoo on mine and I do not see this problem.

Are you using hot/coldplug?

I have the card compiled into my kernel. Should I compile it as a module instead?

I am seeing certain advantages to compiling modules.

Naively, I can't see it making a difference, but maybe it will help. If the driver is a module you can 'reload' it. It might wake up the nic.
