I have 3 routers:

1. Router A with ip class 192.168.3.x

2. Router B with ip class 192.168.4.x

3. Router C with ip class 1c2.168.5.x

All routers have separate internet connections and all are wireless.

I need a way or device through which I can connect these three routers in a way to allow LAN access between all the computers connected to the individual routers. Internet access is not required to be shared between routers since all the routers have separate internet service providers. I merely need just LAN access. Any help will be welcome.

A couple of steps:- Buy 1 more switch- Connect one LAN port on routers A, B, and C to this switch- Modify the LAN ip addresses of routers A, B, and C to 192.168.10.1/24, 192.168.10.50/24, and 192.168.10.100/24 respectively.- Modify the dhcp range of your routers to the following:Router A: 192.168.10.2 to 192.168.10.49, default gateway of 192.168.10.1Router B: 192.168.10.51 to 192.168.10.99, default gateway of 192.168.10.50Router C: 192.168.10.101 to 192.168.10.149, default gateway of 192.168.10.100This should enable all local traffic (192.168.10.x) to only be switched without leaving your LAN segment. From the PC's perspective, it will only use the default gateway if it will send traffic to a destination that is outside the 192.168.10.x/24 range.Hope this helps.

When i Do as you have suggested, the computers are not usign the DHCP of the individual routers but getting DHCP from other routers as well.

Another thing to note is if you are not too particular with regards to the Internet access of the PCs/devices, (i.e., any PC can use any of the three Internet Service Providers without any preference), then you can just use the above setup as it is. There won't be any need for the additional MAC filtering administration. The PCs can just get IP addresses from any of the three routers, whichever provides it first.

1 word: Hamachi.Google LogMeIn Hamachi, its free, its meant to connect people in different locations via a 'virtual LAN' to do stuff without needing to portforward, but I think it'd work in your scenario too.Just set it up on all your computers, make a network, and you're done!Of course this works less well if smartphones need to be on there too... :P

yeah that goes through the internet which would be pointless. the comment below is a way better solution.
