I currently have a wireless connection via a Linksys WRT5G router. The transmitter is upstairs at the front of the house and I have placed it as high as possible. In the front downstairs room the signal is excellent and all is fine but if I move just 10 feet towards the rear of the house I lose the signal. Is it possible to boost the signal somehow to enable the signal to reach the rear of the property? Thanks for your help.
