Hello

I would like to know if it is possible to have 2 separate wireless routers run off a single cable modem connection. The main connection comes into one bldg and then directly into the main wireless router. From the main wireless router, there are network cables run to a separate bldg. Now there are also many wireless access points in the 2ng bldg that are connected to the first wireless router and have the same IP address scheme as the main wireless router. There is a switch in the 2nd bldg that I would like to add a new wireless router. I want this new wireless router to be on a separate subnet from the main wireless network. Lets say the main wireless router runs on a 192.168.0.1 scheme. I would like the 2nd wireless router to run on 10.0.0.1. I would like both routers to have DHCP. The new wireless router is a separate network that will only handle Ipad internet access. There is no need for file sharing of networked printer...just internet access. What is the best way to go about setting this up? Is it even possible? Thanks in advance.

The second router is going to be a different subnet -- so it's own address will be that subnet gateway address (whether 10.0.0.1 or 192.168.1.1, just not 192.168.0.x).

The WAN address used in the second router will be the address of the main router -- so 192.168.0.1 in your case.

The idea is that all requests that come in to the second router that are not within its DHCP range are routed to its WAN address, the main router at 192.168.0.1, which in turn will route those requests out to your ISP WAN address that connects you to the Internet.

Yes, you can add a second router to the switch -- attach the cable from the switch to the WAN port of the second router and give the second router a WAN address and DNS server address that is the gateway address of the main router (192.168.0.1).

You will need to insure that your wireless channels do not overlap between the two subnets or you will get interference. Also make the new subnet radio SSID identifiable as distinct from the other subnet.

Thanks for the response. Just so I have it straight....in the first half of your answer: The second router's IP address should be the same as the first or just an IP on that subnet....like 192.168.0.2?

The DNS part makes perfect sense
