Also perhaps of note is that 'arp -a' hangs indefinitely while the interface isn't receiving traffic. I did notice however that I am still seeing RSTP messages from the router during the outage. The arp command returns some stuff immediately after I bring the interface down then back up. Does anyone have any idea as to how this might be troubleshot further? FWIW, this is the relevant output of 'usbdevs -v': port 4 addr 2: high speed, power 500 mA, config 1, RTL8187(0x8187), Realtek(0x0bda), rev 1.00, iSerialNumber 00C0CA753185 I've seen similar behavior on OpenBSD in years past with various wireless adapters and have never been able to solve it. I don't want to go back to Debian and iptables :(((. -Brian
