[Skunkworks] Live box and coverage and boosting signals

Question: My neighbor just got the Live box on 512. Livebox itself is wifi enabled but I living on the next block of apartments 50m aerial distance cant see the signal unless I go out on my balcony and even then it is a poor signal. There is line of sight btw his house and mine. Will plug in a Linksys router to the livebox and placing it on his balcony do any better? Or is there an easy way to boost the signal?
