FTP will be humming along and then wlan0 will go down.. I have the router set for channel 11... i do not have these types of drops with other wifi capable devices.. ex. WIN laptop, Playstaion 3... etc... rum0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 2290 ether 00:1e:e5:a8:bd:5a media: IEEE 802.11 Wireless Ethernet autoselect mode 11g status: associated wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether 00:1e:e5:a8:bd:5a inet 192.168.1.169 netmask 0xffffff00 broadcast 192.168.1.255 media: IEEE 802.11 Wireless Ethernet OFDM/18Mbps mode 11g status: associated ssid vicnet channel 11 (2462 MHz 11g) bssid 00:22:6b:66:bf:74 country US authmode WPA2/802.11i privacy ON deftxkey UNDEF AES-CCM 2:128-bit AES-CCM 3:128-bit txpower 0 bmiss 7 scanvalid 450 bgscan bgscanintvl 300 bgscanidle 250 roam:rssi 7 roam:rate 5 protmode CTS roaming MANUAL Also yesterday, I lost complete connectivity to the router while my WIN PC was connected and browsing just fine.. I had to bounce the interface and reset the default gateway and my connection restored. I did: /etc/rc.d/netif restart && /etc/rc.d/routing restart Thanks, Justin --623271173-516893176-1292521590=:12484--
