Help with router setup

[MikeRG]

Hi, i am trying to set up the network for my new home, its a big house, i am trying to set up 2 routers to to amplify my WIFI and also my ethernet ports. In the image there are missing devices such as laptops and TVs (ethernet connection) and all the WiFi devices.

 

I cant get to my printer or DVR from my main computer and i dont know what to do.

Both routers are set with DHCP enable with different ranges, the ISP ONT is 192.168.0.1 and the routers are 192.168.1.1 and 192.168.2.1

You're running double NAT. This means you basically have several firewalls in place.

 

Does the ISP ONT include a router?

It has 2 ethernet ports, terrible WiFi and DHCP enable.

Bridge the ISP ONT, you can find this in settings or by calling customer service.

 

Make the first router the primary router. Connect the computer to it as well as everything else. Go to the second router and disable the routing functionality; leave on the WAP and the switch. Many routers have this function, but many don't. If it doesn't, its unsuitable for use as an extender, as everything past it will not be able to "talk" to the rest of the network.

 

EDIT: The router disabling function can sometimes be found as "Disable NAT"

that means i wont be able to connet to the internet from the ethernet ports on the other routers?

No, you'll still be able to use the ethernet ports on the second router. But the ISP ONT ports will be disabled other than one

Hey, This is most probably because you are running three routers as separate firewalls. So clients on ISP ONT wont be able to talk to clients on Router A and B. And clients on Router A wont be able to talk to clients on Router B. I would say, the easiest way to sort out this issue would be to either

1. Set Router A as DHCP and set Router B as DHCP relay to Router A. That way both routers A and B serve in the 192.168.1.0 subnet(But this would mean Main PC still wont be able to talk to A and B but clients on A can talk to B) OR

2. Set ISP ONT as the DHCP and set both Router A and B as DHCP relay to ISP ONT. That way all the routers server in the 192.168.0.0 subnet(All clients can talk to each other.

You literally have 3 routers between you and the internet. Good god man. You need to set the ONT to bridge mode. Then you need to put the second router in AP mode. Only ONE router needs to handle DHCP, NAT and Firewall duties. You literally have 3 separate networks in your home right now. Im not sure what people thing adding additional routers solves issues, its actually creates more problems then its worth.

I already had them never used more than 1 but this house is huge and in the current situation no money to buy WiFi extender

Extenders suck. You need to use multiple access points. Or put your extra routers in AP mode FFS.

You don't need additional equipment if the wireless coverage and speed are satisfactory for your needs. It's just that the configuration of the routers/ONT is not ideal and need to be adjusted if you don't want to run into NAT issues and have all client devices be able to communicate with one another.

 

What you have now are 3 different subnets and, if I might hazard a guess, you're probably connecting each wireless router's uplink via the WAN port. This setup is going to isolate the networks at each segment.

 

The simplest solution here, in my opinion, is to make the ONT the primary router/NAT device. Bind the MAC addresses of the 2 other wireless routers to static IP addresses outside of the ONT's DHCP pool, so that you have something like this...

ONT IP		-	192.168.0.1
Router 1	-	192.168.0.2
Router 2	-	192.168.0.3

Then, configure each wireless router in access point mode. Give it an internal static IP corresponding to the above with the same subnet mask as the ONT and gateway IP of 192.168.0.1, and turn off each router's DHCP server/NAT. You'll have to use one of the LAN ports as the ethernet uplink; other wired clients can use the other LAN ports. Do not use the WAN port on routers 1 and 2.

 

Finally, configure the wireless settings at each access point such that their broadcast channels do not overlap with one another or with your neighbour's. On 2.4GHz you might be limited, so try to utilize channels 1, 6 or 11. There's more room on the 5GHz spectrum. You don't need the highest power output on all access points if adequate coverage can be achieved with low or medium power output at each overlapping wireless node.
