I have a Thinkpad T61 (UZ25FIT) dual boot with Xp and FreeBSD and has an Intel 3945ABG on board. #uname -a FreeBSD yoda.endor 7.0-STABLE FreeBSD 7.0-STABLE #0: Fri Aug 8 13:51:42 CEST 2008 root@yoda.endor:/usr/obj/usr/src/sys/YODA i386 I can load the wpi driver and configure the interface, then I can connect to my wifi router (linksys wag54g 1v) with WPA and surf internet but after a while the wpi disconnects. I think it is volume related and not time related, maybe a counter overflow or something other. If I mount a NFS directory and start copying files from the server to the notebook, after a minute the wpi disconnects. In /var/log/messages I can read wpi0: link state changed to DOWN and in wpa_cli I can read <3>Michael MIC failure detected <3>Michael MIC failure detected <3>TKIP countermeasures started <2>CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys after a minute I read in /var/log/messages wpi0: scan timeout and in wpa_cli <2>WPA: TKIP countermeasures stopped with netstat -ibh I see I moved 12MBytes If I write "reassociate" in wpa_cli, after some seconds in var log messages I read wpi0: link state changed to UP and in wpa_cli <2>Trying to associate ..... <2>Associated with ..... <2>WPA: Key negotiation completed ..... <2>CTRL-EVENT-CONNECTED ..... If I restart the copying process I can see <3>Michael MIC failure detected but wpi doesn't disconnect. After a while wpi disconnects and I have the same messages in /var/log/messages and wpa_cli There isn't a fixed amount of bytes I can transfer between two disconnection, sometime 10MB, sometime 100MB, but the maximum was 140MB Please help me, I can give further info. I have FreeBSD 7 on this PC since its release and I always had problems
