Hi, I have 2 BEFSR41 Linksys router and would like to setup 2 subnet. I tried several times but couldn't get it to work. Router 1 with 192.168.1.1 and router 2 with 192.168.2.1 I have one pc attach to each subnet. Any ideas or instructions. Thanks

those soho routers are not really routers in the true sense of the word. You can get from 192.168.2.1 to 192.168.1.1 and the internet but there is no route from 192.168.1.1 to 192.168.2.1. After all what is a gateway entry for? It's for a subnet request that isn't local. How is a node on the 192.168.1.x subnet with gateway 192.168.1.1 then get to 192.168.2.1? Only way you can get it to work is by setting a static ip on the wan interface of the 192.168.2.1 router [it wan is in the 192.168.1.x subnet] and then do a route add on the workstation that point to that static wan interface as the entry point to the 192.168.2.x subnet. More work than its worth. Example of Oxymoron: Person who is pro choice and anti sex education. Education is key to prevention. Prevent conception you prevent abortion. Abstinence training clearly isn't working.

This is confusing to me. I was under the impression that 192.168.1.1 and 192.168.2.1 were two seperate class C networks. And to connect these two networks to work as a single network requires a bridge. For example, if the routers have the ability in the firmware to configure a bridge, then the two networks could work as a single network. A subnet, I thought, was created using the "subnet mask" (hence the name). 192.168.1.1 with netmask 255.255.255.0 is the entire network, but 192.168.1.1 with subnet mask 255.255.255.240 would be a "subnet" which uses the IP addresses 192.168.1.1 - 192.168.1.14 (network address 192.168.1.0 and broadcast address 192.168.1.15). And then 192.168.1.17 with subnet mask of 255.255.255.240 is another subnet which uses IP addresses 192.168.1.17 - 192.168.1.30 (network address 192.168.1.16 and broadcast address of 192.168.1.31) and so on...

A subnet mask of 255.255.255.240 will give you a maximum of 16 subnets. The first subnet (subnet 0) will have an ip range of: 192.168.1.0 (Network address) 192.168.1.1 - 192.168.1.14 (Usable host addresses) 192.168.1.15 (Broadcast address) The second subnet (subnet 1) will have an ip range of: 192.168.1.16 (Network address) 192.168.1.17 - 192.168.1.30 (Usable host addresses) 192.168.1.31 (Broadcast address) The third subnet (subnet 2) will have an ip address range of : 192.168.1.32 (Network address) 192.168.1.33 - 192.168.1.46 (Usable host addresses) 192.168.1.47 (Broadcast address) And the pattern continues up to 255... Router A and host devices connected to it we can call subnet 0 (maximum 14 devices) Router B and host devices connected to it we can call subnet 1 (again 14 max) There are your 2 subnets but now the routers need to be able to talk to each other... this is where subnet 2 (third subnet) comes into play, they need to have a subnet of their own. They will each be a part of 2 subnets. 1. Router to router 2. Router to host devices Having a subnet mask of 255.255.255.240 is overkill as there can be 14 devices in this subnet, but it offers plenty of room for future routers. You could actually give them a subnet of 255.255.255.252 and that would mean a max of 2 devices can connect but it offers no room for another router in this subnet. I'm not sure what the bridging mechanism is between your routers, but if they need a subnet you have it ready.

"And to connect these two networks to work as a single network requires a bridge." You are mixing layer 2 with layer 3 in the OSI model. You never bridge between subnets you route between subnets.

Thanks for instruction. I agree it is more work, but want to test it out. Wanderer, I don't get your last para saying to a route to add on the workstation. Instruction please. Thanks

Lets say you have 192.168.1.0/24 as your router connected to the internet (call it Router1). It's LAN IP is 192.168.1.1. Attached to that router you have another router with IP 192.168.2.0/24 (call it Router2) and it's LAN IP is 192.168.2.1 Anything plugged into Router1 get's IP's in that subnet with Gateway address of 192.168.1.1 (Router1's IP) and can communicate on the internet. Anything plugged into Router2 get's an IP in that subnet and gateway IP of 192.168.2.1. The two subnets (routers)as they stand, cannot communicate with each other and subnet 2 cannot communicate with the internet. In order for subnet 2 to communicate with the internet you will have to create a route from Router2 to Router1. Without a route between subnets (and routers) the two subnets cannot communicate with each other (although, in a small environment, if you want them to communicate, separating them by subnetting makes NO sense!) AND subnet 2 cannot access the internet. So to sum up, on Router2 you would need to create a route from 192.168.2.0 to 192.168.1.0
