HomeGroup over a local area connection

Question

My network configuration is as follows:

• One desktop is connected by a network cable to the wireless router
• My laptop is connected to the Internet by WiFi (2nd floor)
• The laptop shares the Internet connection with my second desktop via a network cable (2nd floor)

My laptop and the desktop connected by cable to the wireless router are sharing files via a HomeGroup, yet I would like the second desktop to join in.

Is this possible? How?

Answer 1

It needs to be hooked into the same network (physically through router or over wifi).

You could also buy another router and set it up as a bridge to the other router and you can plug your 2nd desktop into the router. This is quite trivial if you set up the second router with DD-WRT (custom firmware for the router).
