Continually losing wireless connection

[Amol Modi <amolmodi yahoo com>]

I've got a Linksys WPC11 Version 3 PCMCIA Wireless Ethernet card running
on RH9 using the orinoco_cs driver. I'm having no problem connecting to
my network initially, but every couple of minutes or so, I lose the
connection. The redhat network configuration tool still shows the device
as active, but iwconfig shows:

eth1      IEEE 802.11-DS  Nickname:"localhost.localdomain"
          Mode:Managed  Channel:-160  Tx-Power=15 dBm
          RTS thr:off

This is incredibly annoying, and if anyone has any idea why it happens,
I'd appreciate the help.
