[newbie] 3Com PC Card Woes

[Andrew Miller]

  Having trouble getting proper configuration for a 3Com 10/100 LAN 
CardBus PC Card 3CCFE575BT on my Thinkpad 760 XL.  Under KDE, the 
card works correctly for a couple of minutes and then just stops. 
Pinging the machine over my local lan then gets no response and I 
can't get to the internet via my DSL connection.  Works better under 
Gnome desktop, but only for longer.  Any suggestions?
