Happy to say I have finally got wireless connection from my laptop. I must say this is one of the least intuitive setup procedures I have ever had to endure. Thank goodness it seems to be over.
UPDATE: (Friday 17FEB06 11.10 GMT) And now I've got it working through my AOL browser, rather than through the clunky IE. The wireless connection is excellent and I envisage doing a lot of my blogging in future from the laptop.
