My family comp. is in the den with a 2wire router plugged in to the phoneline. An ethernet cable connects this to the main computer, and my Dad uses a 2Wire USB to phoneline adaptor for his laptop in the same room. The problem is, I just got a new computer and it will be upstairs in my room, with 1 phone jack. Should I order the same adaptor my dad has or is there another solution because it would be nice to not have to wait another week to get it in the mail.
