I ran both commands, but still no-go. The wlan works fine in Windows, so I know it's not the hardware. Ubuntu just doesn't see the hardware. I found what looks to be the error here in /var/log/syslog:

Since I plugged it into the network on eth0, the upgrade manager has been downloading and installing. Maybe the fix is in there...
Thanks for the formatting tip, I'll format the shared space as FAT32.

and the fix was indeed in there. WLAN is up.
Thanks!
