Well, if you're talking about turning off the power on the
card, then I can't help you. But if by 'restart' you mean
'release the DHCP lease and renew it', you can do

sudo ifdown eth0

to release and

sudo ifup eth0

to renew. Sometimes (like recently) the ifup/ifdown scripts
are hosed, in which case you need to do what those scripts
are supposed to do:

sudo dhclient -r eth0
sudo dhclient eth0

assuming your NIC is eth0.
