	On both Jaunty and Karmic on my laptop I installed the system 
in it's partition and let the new grub control things which it 
always does, and then when up discover WiFi doesn't work. No 
problem right? Just put the password for my WiFi router in 
Network Manager.

	I have NEVER found out where to put the password! So my fix 
is to plug in the Internet and when NM gets that right, I have 
an invocation that goes:

	$ sudo apt-get install wcid

The system reboots and wcid puts up a panel asking for my 
password. I give it and from that point onward it works.

	NM needs a lot of work. It does work fine on wired Internet 
but on WiFi it is hopeless!
