Try searching "Text" rather than "Titles" and you will turn up some
material - largely in the "Laptops" pages.

Agreed that some Wifi info would be a good addition. Not sure the three
categories are the best way to organize, but that is a secondary issue.
I'd propose something like a master intro/index page with a single
sub-page for each chipset, each with a set of entries for individual
driver (your three categories?) and corresponding 3rd party
repos or sources as appropriate
security level (open/none, WEP-40-bit/104-bit,
WPA-PSK/EAP/Radius, WPA2, ...)
system services or daemons (wpa_supplicant, NetworkManager,
dhclient, ...) and config files
tips and comments.

[OT: I have been struggling with wpa_supplicant, NetworkManager,
nm-applet, etc. ever since I decided to upgrade the security on my home
network from WEP to WPA-PSK and the information out there is very
confusing. Every time I think things are working, something breaks
again. What is more frustrating from the CentOS perspective is that the
WEP->WPA transition was relatively painless on two Palm devices, my
Nokia N800, Windows XP on 3 multi-boot systems, and Fedora 8. Only
CentOS-5 (on IPW3945, IPW2200, and Atheros chipsets on some of the same
hardware that works with XP and/or Fedora 8) has been problematic. Need
to post a query to the Users list and see what help is available, but
haven't gotten around to documenting everything I've tried well enough
to pose intelligent questions.]

Don't have to be a tech guru to contribute. If you have something
working it would be worth writing up.

Having a page with Wifi/Wireless in the title will remedy that, as will
a full text search.

I'd be glad to help with a Wifi Wiki effort if I ever get things working
solidly again. I could at least document what was working under CentOS
with WEP and with "open" access points at work and on travel.
