Question mandriva 2006 - wireless interface ra0 becomes unresponsive


hi there,

i'm using the rtx500 driver over mandriva 2006 to connect by laptop (ralink 2500 cardbus card) to a router/broadband modem.

i think the driver came with the distro, but i'm not sure because i also installed the module by hand when running fc4 previously.

my problem is that wireless usually works, but then will suddenly become unresponsive.

i notice because web pages fail to load.

then i've tried pinging the router - it fails if i use the hostname 'homeportal' - 'unknown host'. if i ping 192.168.254.1 it succeeds - sort of:

Code:
[jack@sonja ~]$ ping 192.168.1.254

--- 192.168.1.254 ping statistics ---
30 packets transmitted, 28 received, 6% packet loss, time 29004ms
rtt min/avg/max/mdev = 10.838/7426.603/17012.960/4729.615 ms, pipe 18
ie, it takes about 10 seconds or more for packets to get returned, then 10 or however many packets come back at once.

so i think web or other connections break because they time out.

router provides dhcp and dns, so i think dns times out similarly when pinging 'homeportal'?

i'm not really sure what other logs provide more info on this.

wireless connection in windows on the same machine and from other computers work fine.

i crossposted this to the forums for the driver at rt2x00.serialmonkey.com, hope this is okay, but i have no idea if it's a problem with the drivers. if they come up with anything i'll post it back here, but maybe someone can at least suggest ways to further investigate?

thanks a lot.
