How to connect 2 PC on Livebox

I want to my Livebox to connect two PCs. Firstly, I connect with the wifi while dongle works fine but when I put the second via the USB (I have no ethernet cable and the second wifi dongle) it can not connect. J I do the installation via the CD (adding a new computer).

If someone has a track to get out of there.

Why not go buy an Ethernet cable in a corner shop (type the Universe Computers if they still exist)?Because it will be much faster and simpler than the hassle of connecting a second pc in USB

Yes it still exists. Ok, then I'll try to find a cable.

His works perfectly, thank you.
