I am using the 192.168.1.1 scope for my network I am running out of addresses since are using more wireless devices and systems. How do I add more addresses to my scope of 192.168.1.1 - 192.168.1.255....a superscope??

or change to a Class A.

you could go with a Class B but heck Class A give you about 16k possible networks with a whopping 16 million odd possible unique node addresses for each network. Be tough to run out of addresses if you have 16 million of em per network.

But if I change to class A like 10.0.0.1 then I have to change all my static devices. so There is no way to add say 192.168.2.1 to my dhcp to get it to use those in addition to the 192.168.1.1 addresses???

Connect a second router to the first one.

The first router network IP would be 192.168.1.1 ? 254 as you have now.
One of those should be assigned to the WAN of the second router.
The second router network IP could be 192.168.2.1 ? 254.

There should not be a problem of connecting Internet or accessing the first network from the second one.
However, there might be a problem of accessing the second network from the first one.

there's the superscope.

yes you can do it using a different subnet mask but.... using a Class A, you don't have to worry about running out of addresses.

Cisco kinda came up with a defacto standard that in planning a corporate network, no matter how small, the use of Class A addressing allows for growth.

you might use a different address and subnet mask on a class C to give you more addressing but that doesn't seem to solve the root problem, the plan for company growth. Better to switch to a Class A which gives room for growth that having to continually run of of node addresses. Little pain now vs a bigger pain later on.
