[SOLVED] What's the correct way of setting up dual router

[KsoTy]

I have an old router and currently I have my old and new routers connect to one same modem. I was searching through Google and stumble upon someone connecting a secondary router to the primary router on a modem.

Is this the correct way to setup dual router? If so, what are the differences between these two methods (pros and cons)?

(Sorry for my lack of knowledge and grammar)

One router is for my living room area, and the other router is for the area far from my living room

So - the purpose is to have a router in your every room?

In two different rooms, yes.

It is possible, yes. Most popular solutions here is:

1) Use first router as uplink with WAN in DHCP client mode. Connect second router to first router with Cat5e Ethernet cable in first router LAN socket. Set different WiFi AP name for second router. Pro - will always work with almost no uplink speed loss. Con - you must install Ethernet cable between routers.

Alternative version - you can connect routers over your AC mains wiring in home if both router are connected to same mains phase. You will require a pair of powerline network adapters here. This will spare Ethernet cable installing. However network speed to second router may vary accordingly to mains wiring quality and specific in your home.

2) Connect routers wirelessly in WDS bridge mode. Pro - no need to install anything between routers. Cons - routers must remain in distance acceptable for WiFi communication quality between them. And you will get only half of possible WiFi speed for second router WiFi clients. Plus even more clogged WiFi radio space if you are living in some multi-story apartment.

So - the purpose is to have a router in your every room?

He very likely want to have even WiFi coverage in his home or apartment.

Possible.

May be he just likes blinking lights on router box.
BTW - not all routers have wifi in them.

If you only care about using the internet you won't have a lot of issues. If you want to connect you another other client thats not on the same router you will start running into problems. Ideally you would just want one router and have the others as access points. Another issue is nesting them and trying to use the same subnets on every router and the defaults are usually the same subnet.

the only problem you might run into is IP conflicts , you can elevate this problem by changing your two routers' default gateway address and changing the DHCP address range too to make sure there is no IP conflict whatsoever ..
