Linksys WMA11B "waiting for host"

Hello,
I just got Linksys Wireless-B Media Adapter WMA11B. I can ping it over
my wireless network, no problem. I've got WEP as well as MAC filtering
enabled. My wireless access point is Cisco Aironet 340.
When I power up the Linksys box, it displays "waiting for host" on the
TV and that's it. The signal strength it is reporting is 92%. My
desktop running the Linksys s/w is Windows XP Pro.
Any ideas ?
Thanks,
Jarek

 

Looks like I fixed my problem - on Windows XP, disabling the firewall
for my wireless interface did the trick. I was not able to get info
from support on the ports that WMA uses to connect back to the PC,
though.
