I noticed that the AP was hiding its ESSID, so I did a
manual

iwconfig eth0 essid laniel

then did an ifdown/ifup, and the router came up fine. Now
when I do an iwlist eth0 scan, I get

eth0      Scan completed :
          Cell 01 - Address: 00:12:17:C5:9C:8F
                    ESSID:"<hidden>"
                    Protocol:IEEE 802.11bg
                    Mode:Master
                    Channel:6
                    Encryption key:off
                    Bit Rate:54 Mb/s
                    Extra: Rates (Mb/s): 1 2 5.5 6 9 11 12 18 24 36 48 54 
                    Quality=86/100  Signal level=-44 dBm  
                    Extra: Last beacon: 228ms ago

which is the proper information for my router. But I don't
get the neighbor's router, with a publicly-broadcast ESSID.
It used to be that I'd get the neighbor's router, but not
our own. There's something screwy afoot.
