The original title was going to be:

But it was going to be long and boring. Ok, everything started because I have moved to a new location and I was not going to have internet in a long time nor willing to get a two year contract with a company again.

Fortunately I have this hardware ready to be set up:
VIA ARTiGO Pico-ITX Builder Kit A1000
Alfa AWUS036NH
WiDrive DX325
I could explain the network, but better seen graphically:
