Look for available wireless networks. Click on the one you want to connect to. If they have a password, then you have to enter the password.
I have a HP laptop with windows Vista. So many places, motels, Starbucks, etc., apparently allow their customers to hook up to the internet with wifi. Can someone please advise or refer me to a website that will explain how to set up my computer and exactly what I need to do so. Thanks.
