That is certainly likely ... The state of wireless cards and firmware on
Linux is not yet wonderful, some wireless devices work great others do not.
I have a Intel 2200 device (Intel Corporation PRO/Wireless 2200BG
Network Connection) ... and it uses the ipw2200 driver. Other than the
fact that I had to get the latest firmware from Dag's repo, it works fine.
I would certainly recommend trying NetworkManager first and if it does
not work, then going the other route.
I was able to use the wpa_supplicant and its conf file to make this work
too, but it was much harder and NetworkManager is great everywhere I go
to get connected ... of course YMMV :-D.
