I think I posted a link in your original thread for a suitable dongle. Something like
this should work like a charm and it is the bargain price of £20 with free delivery. If you ever fancy making the jump to supreme awesomeness I would also suggest investing in a Linksys router such as this

In fact, as they are only £36 (cheapest they have ever been and is an amazing price for the calibre of the router) I would very strongly suggest you get one
now (along with anyone else reading this who needs a new router or is having a problem with the shub).
£56 for a cracking router and wireless dongle from Linksys is a supreme bargain. They are going to kick ass and provide you with stability, performance and reliability for a long time and is well worth the investment.
