how to redo networking on bootup

[Paul Cartwright <ale@pcartwright.com>]

I think something is wrong with my system. It started a few weeks ago, when, 
on a reboot, my NVIDIA driver didn't work, so X didn't start(or is it X 
wouldn't start because I had no network..). I think somehow these are 
related, but I don't know how.

anyway, I just changed DSL providers, and in rebooting to get it setup, I am 
noticing that my network doesn't come up clean any more, now I have to 
restart networking, then do ifup eth0 to get back on the network.
How can I get it back TO NORMAL..
