wireless card problem - DHCP ok

Hey everyone

I have a little problem. I have a dell inspiron 8000 laptop with
redhat 9 installed. I also have a linksys WMP11 pcmcia card that i
use to connect to my wireless net. Im having a problem getting it to
connect to the network. I get an IP via DHCP, but i cannot ping the
gateway or any other host on the network. I can only ping my own
ethernet interface. The data LED is blinking at a constant rate, but
if I do a tcpdump on the interface, there is no data on the
line...absolutely nothing. Any ideas??

TIA
Rob
