It's configured to use ipsec and seems to work very well except 'Daily' reports an ever increasing number of 'Ierrs' far in excess of 'Ipkts' and 'Opkts'. Without any traffic on the card the counter seems to increment by about 20/sec. I also notice the two LEDs on the card are flashing at about 0.5 c/s. It's my first experience of wireless so I have nothing to compare it with. Should I be worried? Is this common for wireless cards? > grep ath /etc/rc.conf ifconfig_ath0="inet 10.10.20.1 netmask 255.255.255.252 channel 7 ssid skew_wifi mode 11b mediaopt hostap" > ifconfig ath0 ath0: flags=8843 mtu 1500 inet6 fe80::211:95ff:fe91:8cdf%ath0 prefixlen 64 scopeid 0x4 inet 10.10.20.1 netmask 0xfffffffc broadcast 10.10.20.3 ether 00:11:95:91:8c:df media: IEEE 802.11 Wireless Ethernet autoselect mode 11b status: associated ssid skew_wifi channel 7 bssid 00:11:95:91:8c:df authmode OPEN privacy OFF txpowmax 0 protmode CTS dtimperiod 1 bintval 100 > netstat -i -I ath0 Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll ath0 1500 00:11:95:91:8c:df 0 1685321 2 0 0 ath0 1500 fe80:4::211:9 fe80:4::211:95ff: 0 - 4 - - ath0 1500 10.10.20/30 10.10.20.1 0 - 0 - - 10 seconds later: > netstat -i -I ath0 Name Mtu Network Address Ipkts Ierrs Opkts Oerrs Coll ath0 1500 00:11:95:91:8c:df 0 1685515 2 0 0 ath0 1500 fe80:4::211:9 fe80:4::211:95ff: 0 - 4 - - ath0 1500 10.10.20/30 10.10.20.1 0 - 0 - - -- John.
