Isolated wireless network within existing wired network

[WhiteKnight]

I have an existing wired network with a router located at 192.168.0.1 and a DHCP range of 192.168.0.100 to 192.168.0.199. I want to add an isolated wireless network. Right now, I have the wireless router attached via its WAN port to a normal port on the wired router using a straight-through cable. I tried to set the wireless router IP to 192.168.0.2 and have its internal IP as 192.168.1.1, with a DHCP range of 192.168.1.2 to 192.168.1.24. I can connect the the wireless AP just fine, but there's no internet for the wireless clients. If I turn off the wireless DHCP, internet for wireless clients works just fine, but of coures then the wireless clients are getting IPs from the wired router and are on the same subnet as the wired PCs, which is not what I want. Any thoughts here?

Edit: Also, if I allow the wireless router to get its IP dynamically (via the wired router DHCP), everything works. However, I want to be able to assign the IP for the wireless router manually.

I do not know what is it that you would like to isolate.

The way you trying to set it up that Wireless Network would be able to access the wired Network. While the Wired Network will not be able to connect to the Wireless.

The Network that needs to be protected has to be on the second Router behind double NAT.

Maybe isolate is the wrong choice of word? I basically want the wired router at 192.168.0.1 distributing IPs to wired clients with a DHCP range x.x.1.100 to .1.199 and the wireless router at 192.168.0.2 (attached to the wired router, but 192.168.1.1 to wireless clients downstream) distributing IPs to wireless clients with a DHCP range x.x.2.100 to .2.199. So, wired clients see the wired router at 192.168.0.1 and wireless clients see the wireless router at 192.168.1.1.

Can you get another IP address from your ISP?

That would make things a lot easier.

Nope, this is all just running off of a cable modem.

Have you checked a failing workstation for what its IP information is? From the description of your problem, I would say you are getting an invalid gateway or subnet mask. Just a guess.

I have the similar setting using Netgear Router as primary and old SMC 7004WBR as secondary and it works OK.

Actually my setting is even more complicated since the first Router is Wireless too. I use it to experiment how WZC ?Jumps? from one Wireless source to another.

Check your setting or try another Router as a secondary Router.

Thanks for the ideas. I'm hoping to be able to mess around with it a bit more after work today.

You need to enter a route in your router for the 2nd subnet assuming you are using a subnet of 255.255.255.0 i.e. /24
