I now have both my Dell laptop and my iBook hooked up to my Airport Base Station, using WEP. I had originally disabled it, because I thought the USR card on the Dell wasn’t compatible with the 40-bit WEP implementation on the Airport Base Station. The USR config software only had options for 64-bit and 128-bit WEP. Little did I know that 40-bit and 64-bit are the same thing. And little did I know that the Airport Admin utility has a menu option to convert the text password used by Airport into the hex key required by the USR software. This nice little article explained it all: Flying into Other AirPorts. Yay for TidBITS! They rule!
My efforts to get WEP running again were of course spurred by Sunday’s Doonesbury.
