Linuxant wlan connection dropping

Hi,

I have a linux server with a netgear WG311 wifi pci card installed. The
idea is that this server can sit in a cupboard and connect to (and be
connected to), through my netgear DG834G wifi router. The problem is
that the linux server keeps dropping off the network, unable to ping,
etc.

When I get a console on the server and run iwconfig it says that it's
not connected, with no signal strength, etc. If I reboot, it's fine for
a while and then just drops off.

Theres no issue with proximity.... it's going through 1 wall and about
10 feet, when connected it gets 100% signal strength.

I'm using linuxant driver which is installed on a linux 2.4.21-144
kernel (custom built from Suse 9 src). The card is running in "managed"
(same as infrastructure mode I think)

Everything works, it's just the connection dropping thats driving me
mad. I must stress I'm using the box as a server, and not as a client.

I'd appreciate any advice greatly.

Many thanks,

James.

For more info here is what iwconfig says: -

As you can see link Quality is not bad(!)
