Dell D505 Intel Pro/Wireless - no DHCP

A new Dell D505 with Intel Pro/Wireless 2200BG will not connect to my
wireless access point if WEP is enabled. It gets a bogus IP of
169.xxx.xxx.xxx.

If WEP is disabled, it connects right away.

I have another notebook with a Linksys Wireless card that works fine on
the same Access Point with WEP enabled.

I have tried entering the WEP passcode in the Dell/Intel Pro with both
the Alpha-Numeric characters and the HEX characters. The same results:
IP of 169.xxx

Any suggestions?
