i don't see any reason to buy an antenna for my current router.. because theres gotta be something wrong with it. For the first couple years.. it worked great anywhere in the house. Now, you walk 10 feet away from it, and the connection drops completely.

I do have a question though.. i want to upgrade to Verizon FIOS as soon as its available here (its available 5 miles from me already...).. what kind of router would i need for this?
