My only consolation is that this fault is not intermittent. :-( Here's what happened. I emerged a different (to my tried & tested rt2x00-9999 wireless driver). Then I uninstalled rt2x00-9999, but I couldn't get the new driver to work. So, I unmerged it, remerged rt2x00-9999 (this is a CVS package) and I have not been able to make it work ever since. I even recompiled the kernel in hope of getting it to work, but I can't get it to detect any Access Points: ===================================================== # /etc/init.d/net.wlan0 restart * Starting wlan0 * Loading networking modules for wlan0 * modules: apipa arping ccwgroup macchanger macnet rename ifplugd iwconfig essidnet iptunnel iproute2 pppd system dhcpcd ip6to4 * ifplugd provides plug * iwconfig provides wireless * iproute2 provides interface * pppd provides ppp * dhcpcd provides dhcp * Configuring wlan0 for MAC address 00:11:50:18:55:3F ...

Here's some additional relevant info:

Would you perhaps know how I may be able to troubleshoot this thing before I
lose my temper and throw it out of the window?
PS. I might have un/plugged it during probing/scanning - could that have
caused some physical damage?
