You should be able to connect for long periods of time with no problem. One thing you should read is
this. The basic facts are that you should set up the wifi once in just a couple clicks, then you should be able to connect all the time with ease.
I am far from an expert, but in my opinion it should be as easy as connecting on the desktop. The Odyssey Client, while I'm not sure how it works, seems to work in the background to make things happen, so keep that in mind. I just use IE and don't do anything fancy.
If you have trouble after reading the Wifi guide, let us know.
