Hi, Anyone care to elaborate on what I've goofed up? I've read the man page about 4 times, and I believe I have exactly 26 hex digits. It's also the exact key all my *ugh* wintel boxes have on them: water# ifconfig wi0 wepkey 1:0xbb2cc2093f788f0ebb67d28abd ifconfig: SIOCS80211: Invalid Argument water# Thanks, Steve
