One of my Linux boxes, having a wireless NIC, connects to a remote machine and suddenly started disconnecting. Sometimes this wireless device disconnect after an hour, sometimes after 10 hours or sometimes after 27 hours but I have to keep this machine running for at least 5 consecutive days without interruption.
This Wi-Fi stack connects to a 802.1x WPA2 enterprise and the Access Point is just three (3) feet away from the machine (running in stationary mode).
Nothing relevant to Network seems to be logged in dmesg, syslog, klog or any other /var/log.
How should I proceed?
