Hi,
I noticed there was some changes in the ath code. But it has little to 
no effect on the periodic drops of the radio signal. This time, 
suddently, the input is garbaged; at least, the card say so:

PM : ifconfig -v ath0
ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
         ssid vincent nwkey *****
         powersave off
         bssid 00:0f:b5:61:4c:94 chan 4
         address: 00:0f:b5:64:19:a8
         media: IEEE802.11 autoselect mode 11g (OFDM36 mode 11g)
         status: active
         input: 480 packets, 243876 bytes, 24 errors
         output: 456 packets, 56191 bytes

At each ping, the input errors accumulate and nothing short an ifconfig 
down/up can restore the IP level.

Anybody else experiencing the same problem?

Vincent
