Linksys EZXS55W Switch Weird Behavior.

[BobHelms]

IBM laptop with Intel PRO/100 VE NIC. Trying to connect through a Linksys EZXS55W (5 port) switch, won't connect. Tells me I have a limited connection. Status shows no received packets. Bypass switch by plugging directly into Netgear WNDR3400 router, no problem. If I connect a different laptop with an Intel 82579LM NIC into same EZXS55W switch it works. I then connected the IBM laptop using a Linksys EZXS88W (8 port) switch, it works. Any ideas as to what could cause the PRO/100 VE NIC and the EZXS55W switch not to work together. TIA for any help.
