My ISP gave my /29 IP block years back. I was using within my LAN using Linksys and other devices. On my request for more IP's my ISP have given me /28 block. My question is how to use it in LAN with my existing Linksys wireless as I want to add more devices within business ? Thanks for the best solution.

You can implement VLANs and throw that subnet into a different VLAN or break it into two /29s and throw them into two different VLANs. Or you can just configure it as a subnet extension on your current LAN.

You should be able to give your Cisco router an IP from that subnet with the following command:

ip address x.x.x.x x.x.x.x secondary
