We recently installed two wireless access points on the 5th floor of Chamberlain Hall--one in the print room and one in the "grad student bullpen". The network name name (aka "SSID") is "Chamberlain Airport" and the password (aka "40 bit WEP key") is "rader". (No, I did not pick that password!)
If you have any problems, or find gaps in the WiFi coverage on 5th, please let me know.
You can check that status of the UW-HEP WiFi network here:

Our AirPort Extremes have been locking up for almost a year now, and the problem has gotten really bad with the new 5.6 firmware. After some investigation, we believe the instabilities started after upgrading from the 5.5.1 firmware, so we've downgraded to the 5.5.1 firmware.
The UW-HEP WiFi network ("Chamberlin Airport") is now password protected (by a 40 bit WEP key.) If you need UW-HEP WiFi access or have any problems or questions, please don't hesitate to contact me.
The conference room AirPort base station wedged last night. Thank god for Nagios. The AirPorts are cheap and easy to manage, but it seems that they're not exactly a "enterprise quality" product.
All of our Apple Airport WiFi access points wedged today over a four hour period. I don't know why.
