[ale] Best WIFI stuff for Ubuntu 9.04 Jaunty?

[ale at sixit.com (ale at sixit.com)]

Hey everyone,

Quick survey...  I'd like your opinion on the best WiFi USB adapter (with
or without cord), best router, and best wifi manager (WICD,
NetworkManager, etc.) for using Gnome and possibly KDE, E17, etc. on
Ubuntu 9.04 (Jaunty).

Also, any gotchas you've run across in hooking up a second wifi router
to a first wifi router in order to give private, secured internet access
to machines the second router?  I've done this many years ago without
issue, but today's routers are quite a bit more advanced yet dumbed-down.

Thanks much,
Robert~
