Help to hook 3 different routers together to get internet all thru my home

Post by tlryan »

My problem here is that I don't know the proper term used to define what I would like to do so it’s hard to search. We have a Linksys WRT120N router, a Motorola sbg901 router, and DSL coming into our big house with Windstream wireless modem Fast 1704n.
What I am trying to do is hook up all three units. I have the DSL coming in on Fast 1704n hooked to the Linksys WRT120N by way of Ethernet. That works good without a problem. I get a good signal from both and they both work well. When I run Ethernet from Linksys WRT120N to Motorola sbg901 I lose internet on both Motorola and Linksys but keep internet with Fast 1704n. How do I achieve the internet from all three hooked together. :~(

You would just carry out the extra step for the third one.

The best way to accomplish this is to leave only one router/device as a NAT Router (serving private IPs dynamically, usually in the 192.168.*.* range), and set the remaining routers as access points (using their lan ports, not the WAN ports, but connected via Ethernet).

Looking at your Fast 1704 DSL router, it is configured as a NAT Router already and it has 4 LAN ports: http://www.speedguide.net/routers/sagem ... outer-1964
It's default LAN IP address for web configuration is 192.168.1.1

I would set both your remaining routers as access points (connected via Ethernet to the Windstream router), using the guide here: http://www.speedguide.net/articles/how- ... point-2556

I would set the two remainging routers manually to consecutive IPs, i.e. 192.168.1.2, 192.168.1.3 (net mask: 255.255.255.0, Gateway: 192.168.1.1, DNS: 192.168.1.1 and 8.8.8.8 or your ISPs).
Set all three on different wireless channels (1,6,11), using the same type of security and passphrase.

That way, all three will be on the same subnet, you will be able to configure them using the above IPs in your browser, etc.


Notes:
Setting up your routers as access points is much better/faster than repeaters, with the only caveat that you need ethernet cables between them.
You should exclude the above manually configured IPs from the DHCP range on the main router, i.e. don't include 192.168.1.2 and 192.168.1.3, let DHCP start from an IP above that, 192.168.1.10, for example.
