rossi, use a Linksys access point/router. I did and was able to make it work just by going with the 'quick install' sheet. Here's a board with some useful info [not too many posts, so you can browse them all] http://www.siliconinvestor.com/stocktalk/subject.gsp?subjectid=52949
I've heard good things about Linksys tech support but have never used them myself.
Since my installation happened a year ago, I've forgotten details by now.
