Is there a way or additional hardware that will boost the strength of wifi in my house. I have router connected to AirPort Extreme which is great in that part of the home but very weak reception on second floor far from unit.
To start check out the following Apple Support article on how to extend an AirPort Wi-Fi network with additional AirPort base stations. You will be presented with at least two options. The basic difference between them is that one option uses all wireless connections, whereas, the second requires all base stations to be interconnected by Ethernet.
If you want to increase wireless range and coverage try mounting it on the ceiling or wall like with this product:

It optimizes the 11n/ac speed and throughput so that you can get great performance from your Apple Extreme throughout the entire house!
I may receive some form of compensation, financial or otherwise, from my recommendation or link.
