Computer 1 - downstairs Connected to the modem/router via usb . Computer 2 - upstairs connected to the modem/router via ethernet . Computer 3 - outside in the shack, connected to C2 via wireless card.
C1 and C2 connect to the internet through the modem/router via their respective usb/ethernet connections.
C2 and C3 connect to each other fine (the signal strength is -31db - and that is good enough for full rate data exchange).
....... but no matter what I try I cannot get C3 to connect through C2 to the internet.
