I have a linksys access point plugged into a hub which is my local LAN. I am
trying to get my new Thinkpad T41 (running XP) to connect to my LAN. What
follows is an IP trace of what happens. At the end of this sequence XP has
dropped the linksys access point from its list of possible connections.
MAC address "00:0C:F1:28:89:7E" is the T41.
MAC address "00:02:55:AA:83:2F" IP 192.168.1.1 is the gateway PC.
My DHCPSD.CFG is at the bottom of this message.
I am hoping that someone knows what else I need to do to get the T41 to connect.
