Increasing Wi-Fi Signal

Is this valid? Are there other methods in order to increase the range of a signal? There is a place close to my house that is free Wifi, but inside my home, I only receive one bar, and the connection is unstable.

Advice?

I'm not sure about the wi-fi thing, as I've never needed to try it myself, but it looks like it would work.
