The reason why one of your computers is not getting the internet is because your network is not on the righ LAN.

Got to internet-tool-options-connections-lan settings- uncheck the prefex server-make sure all thoose boxes are checked. and un check the oxes above it.

@OP Can you run ipconfig in a command prompt and post the results back here?

I suspect you're having problems with DHCP.
