Hi all,
I have Thinkpad R61i (with Intel(R) PRO/Wireless 3945ABG wi-fi adapter)
running FreeBSD 7.1 RELEASE.
Access point is ASUS WiFi-AP Solo (embeded in ASUS P5B-MX motherboard)
Sometimes (2 - 3 time in hour) FreeBSD loses wifi connection to AP.
In some cases connections appears again after 2-3 minutes,
in some cases i need to /etc/rc.d/wpa_supplicant restart wpi0 to restart
connection,
in rare cases system crashes, leaving dump.
I had similar problem running Ubuntu 8.10 on the same notebook (exept
for crashes),
and no problem running windows xp.
Could you help me to fix at least crashes of system ?
