wireless suddenly not working (iwl4965)

[Peter Smerdon]

Hello, I have xubuntu 7.10 installed on my HP UV9000 series laptop.
I don't recall doing anything special during installation to get
wireless working, it worked right out of the box.

kernel is 64bit 2.6.22-14-generic
modules loaded are:
iwl4965 113512 0
iwlwifi_mac80211 200456 1 iwl4965

sudo iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

So now all of a sudden I have no wlan0 device.
here is some dmesg output:

sudo lshw -C network

       configuration: driver=iwl4965 latency=0 module=iwl4965

but as you can see, no `logical name:' entry...

So, what is the next step? what can I do to troubleshoot this?
Thanks in advance
