First, I'll spit out pertinent machine information - uname -a: FreeBSD hautlos 6.0-STABLE FreeBSD 6.0-STABLE #3: Sat Mar 11 16:26:58 CST 2006 root@hautlos:/usr/obj/usr/src/sys/HAUTLOS i386 pciconf for the card: ath0@pci0:12:0: class=0x020000 card=0x3a131186 chip=0x0013168c rev=0x01 hdr=0x00 vendor = 'Atheros Communications Inc.' device = 'AR5212, AR5213 802.11a/b/g Wireless Adapter' class = network ifconfig ath0: ath0: flags=28943 mtu 1500 inet6 fe80::211:95ff:fe8d:1379%ath0 prefixlen 64 scopeid 0x3 ether 00:11:95:8d:13:79 media: IEEE 802.11 Wireless Ethernet autoselect mode 11g status: associated ssid deutschland channel 6 bssid 00:11:95:8d:13:79 authmode OPEN privacy OFF txpowmax 36 protmode CTS ssid HIDE dtimperiod 1 bintval 100 The ath0 is briged to a dc0 interface through netgraph. This is the behavior I've noticed; at seemingly random intervals I will get a device timeout thrown out to dmesg from the ath driver. Reading the ath manpage, I see that "This should not happen." Most occurrences do not yield any perceivable change in the connection. However, sometimes the windows wireless clients I have associated with this machine will not be able to receive anything over the wireless link unless they trigger it by sending something over the radio. Sometimes the windows clients will straight up lose track of the machine completely and scan for other networks. I've not been able to replicate the problem from a FreeBSD client. I desperately need to troubleshoot the problem, as my wife is getting frustrated with losing connectivity to my "stupid computer" (which is the gateway for our network) and I can't cook very well. ;) The difficulty I'm having is that I don't know where to start to solve this particular issue, and I've seen no other users with the same problem. I'd appreciate any bumps in the correct direction. Thanks, Reid
