argh -- can't get wireless in someone else's house

[inforainbow at infinito.it]

For my experience is not a router problem nor a wireless 
card problem.iwconfig has nothing to do with this issue 
you can use how many parameter and the order you want.

The problem can be focused on which firmware uses the 
wireless card driver or on which version of dhclient is 
used on the machine.

I've experienced this problem with Ubuntu 7.10.
Ubuntu 5.10 works perfectly on the same machine inclusive 
wireless.

I cant start Fedora since version 7 because it crashes due 
to the version of xorg used.

Newer Linux doesn't mean better but worst for older 
machines.

Bye
