[GRLUG] Ubuntu and Wireless

[Godwin]

Use "modprobe" as it will do some param stuff *automagically*.  One
thing I've learned about Ubuntu and wifi cards, there exists a
directory "/lib/hotplug" or "/lib/firmwares" or
"/lib/hotplug/firmwares" (I don't have access to my box right now),
which contains a plethora of wifi card firmwares under a directory
named "2.6.15..." or whatever kernel version you have.

I've always kept a tar'ed up copy of that dir as it tends to disapear
after kernel upgrades.  I simply untar my copy, rename it to match the
kernel and reboot.  Magically, the firmware for my Intel 2200bg wifi
card gets downloaded onto the card and it works like a charm with WPA.

I recall having to do that with Warty a while ago.  It's now embedded
in my ubuntu brain...  :-)  On a diff topic, Novell (gnome) SuSE 10
rocks!!!  ;-)
