Nah, no help.

Some more interesting observations: (now that it has happened again)

- If I restart AP, no help
- If I disable WPA2 on the AP and connect with no security at all, it works
- If I re-enable WPA2, it fails to connect again
- Syslog reveals nothing (same messages as in dmesg)
- It took this time a bit over a day for the n900 to drop off wifi, last time it did it in 5 hours and the record is 5 days of being connected
- Tried restarting networking (no help) and wlancond (no help either)


I wish there was some way to debug this... maybe I'll go and read some documentation now
