Did an update, which seems to have gone off well except for an error with postgresql not having a certificate, which I fixed.

Sadly, wifi no longer works. As I was doing the update through wifi, I know it was working until then. (It didn't break until reboot.)

Here's what I've tried:
Code:
update-rc.d -f dhcp3-server remove
update-rc.d -f apache2 remove
(which did remove some entries, but no luck)
Code:
sudo start-network
Code:
sudo /etc/init.d/networking start
After starting the network I do see interface lo and eth0, which I take to be the wired network, but nothing else (like, say, eth1).
Code:
sudo iwconfig
tells me neither lo nor eth0 has wireless extensions.

Google has failed me. Can anyone help? Thanks in advance.
