I've just installed Ubuntu 10.04 on my Samsung netbook alongside Windows 7. I cannot connect to my BT Home Hub from Ubuntu but it works perfectly in Windows.
The general issue of wireless conectivity in Ubuntu appears to be a common problem judging by the number of discussion threads I've found on this subject. However none of them offer any straightforward advice to solve the problem that makes any sense to a relative novice (me!).
I don't undertand a lot of the acronyms and jargon that get posted to these sites but I can follow step by step instructions so if anybody can provide such a thing I will be very grateful.

This should tell you whether or not your wireless adapter is actually seeing the homehub.
