While visiting my sister during the holidays I got to talking with my Bro in law about Wifi...Tv... Internet etc. Next thing I know... he gives me a Router. Then he E-mails me a YouTube video on "How to hook it up to a cable modem". The problem is...I don't know what he had in mind and I didn't ask. I've always had cable Tv and Internet and don't know anything about Wifi but I'm thinking the router has to do with the Tv. And I feel stupid asking him why he gave me the router. Any ideas?
