Windows 7 Info needed on wifi extenders and dual band routers?

[lorenkjr1]

I am looking around for things that will help make my Verizon Fios Internet connection both stronger and faster. I have a 35meg. connection which at best seems to yield around 4 to 5 megs. per second. But, that of course is if I am in the house itself; and not outside like on the patio or porch. Would a wifi range extender be a good idea? And whats a good brand or model that you would recommend? I have a Verizon Fios router which has gigabyte ports but, will not access the internet at that speed. It only produces the gigabyte mode, when doing things from computer to computer. Might a dual band router be a possibility, along with the Verizon router?
