Now with FreeBSD 9.2_STABLE not rebooted on living-room computer, I can log in to router from bedroom computer with
using System Rescue CD with Midori web browser, but I still can't access the Internet from there.

But from living-room computer, I can't access at all as I did before.

Maybe FreeBSD stumbled over itself and changed IP addresses?

/etc/resolv.conf shows

# Generated by resolvconf

/var/log/messages showed, amid a whole lot of pulseaudio error messages,

New router (re0)
New IP address (re0)
New subnet mask (re0)
New Broadcast Address (re0)

but I can't log in to router from living-room computer either at, or .

So FreeBSD might have corrupted something that hopefully would be resolved on reboot.

I did reset the router with the pin-through-a-hole, also powered off and a minute later back on, but that didn't resolve anything.

Did you regain login access to the router?

How do you regain login access to the router if you change its IP address and then forget what you changed it to?

I guess the pin-through-a-hole reset would get you back.

I have some things to do that I don't want to disrupt before rebooting living-room computer.
