    Hi...

    I have a PCs with 2 network cards on each PC.

    One network is already working with 192.168.1.1...50 and subnet of 255.255.255.0.

    Now I need to setup 2nd network. For that I tried setting up the network with 192.168.1.101...150 and subnet of 255.255.255.0.

    I saw that the first network is not anymore. I tried disabling the 2nd network. Then 1st one works fine...

    Any idea? what is wrong? What IP addresses and subnet I should use for 2nd network?

    The two networks you've classified are still referring to the same network. In other words based on the subnet mask you're using, 192.168.1.23 is still on the same network as 192.168.1.123. If you want to split the class C network to follow what you want to do, you'll have to use a subnet mask of 255.255.255.128. The first network created from this will have a network address of 192.168.1.0, hosts in the range of 192.168.1.1 to 126, and a broadcast address of 192.168.1.127. The other network will have a network address of 192.168.1.128, hosts in the range of 192.168.1.129 to 254, and a broadcast address of 192.168.1.255.
