Lost connection, need help

[Sight]

This may not be the right place, but it's network related.

I have a machine running pcbsd9.0, up until a couple of days ago everything was fine. Now I cannot connect to my network or even access the router, I can run a live distro from the box and the network runs fine so I don't think it's really a hardware problem.

The only thing that I can think of to cause this was that the power went out for about an hour before all this started happening, but the box wasn't even on at the time.

It's a wired connection btw. Any suggestions? I'm pretty sure a fresh install would fix it, but I don't really want to take that route right now. Thank you

What does ifconfig say?

Is there still an entry for that interface in /etc/rc.conf?

Is this what you were looking for in /etc/rc.conf?

ipv6_activate_all_interfaces="YES"
network_interfaces=re0
ifconfig_re0_ipv6="inet6 accept_rtadv"
ifconfig_re0="DHCP"

I suppose I should add, I have a router, but then the connection goes through a d-link.

Everything looks good. Are you positive it's not hardware related? Realtek's tend to have a flaky reputation on FreeBSD.

Everything worked fine up until about a week ago when I lost connection, and I can boot up a live distro and get it to work. If it's hardware related, it picked a funny time to start.
