Re: Strange Wireless Network Degredation Problem

I have a strange wireless networking problem at home.
The scenario is that I have a Debian Lenny server which I have wanted to
move, so have added an Edimax EW-7128G wireless card. I have removed
the reference to eth0 in /etc/network/interfaces (and removed the cable
from it to my ethernet switch) and replaced in with one which brings up
wlan0 with dhcp (and wp_supplicant to proved the wireless networking
ssid and passwork).
When I first bring up this network I can ping this machine from other
machines in my network fine - but after about 30 seconds or so, the
networking degrades, and I get 70% packet loss. On the otherhand,
pinging out from this machine to others on the network always works with
no packet loss
I have other wirelessly connected machines (through the same wireless
access point) and I can ping these fine with no packet loss so the fault
seems to be related to my server rather than the wireless access point.
I have run wireshark on from my desktop (where I am pinging from) and
can see 4 or so pings go out and only one reply come back.
I can run uptables -L -v from the server and it is counting up the
packets coming in and going out and they are balanced. (ie its not
seeing these extra incoming pings at the iptables level)
I am not sure where to go next
Anyone have and ideas?
I had one private reply to look at all the various other machines
configs to check I had no overlap of ip addresses, but I can find
nothing. Running wireshark on the actual machine itself shows it never
receives the missing messages, whereas I can see them going out of the
sending side all right.
I've googled around the internet for others experiencing problems with
rt61pci module, but there have been no recent problems.
