Lan Connection Showing Unidentified Network & No internet access

Hi!
I have 2 desktops with Windows 8.1 installed on both. I use Internet using Reliance Netconnect USB card. But I cannot share the internet between the 2 systems. I can access the files and all except for Internet. I have checked all the IP series

I using following IP Series

PC 1 - 192.168.1.1 Subnet Mask: 255.255.255.0
PC 2 - 192.168.1.2 Subnet Mask: 255.255.255.0

Please help me to resolve this problem.

Thanks Norman
