From the article: Can Two Routers Be Used on the Same Home Network?
Using two routers on a home network can be a good idea for a few reasons including increased security and performance. Some people may need a second router if their first one doesn't support a certain type of connection or home gadget. Some may even like to keep a second router on their network as a fallback option in case one router fails. What's your story? Share Your Reason
One router per IP address
- I'm not an expert, but I have learned a few things over the years about networking and generally, one router does the trick. You only need one box assigning IP addresses. There are some instances where you would put a router behind a router, if you wanted to, sa,y use your wireless router behind a U-Verse Gateway that has a built in router. But I have 3 routers set up in my network, only one of them is acting as a router. On the other two I have disabled DHCP. As long as you don't use the WAN port to connect anything, the unit will act as a switch or a Wi-Fi access point. so, 2 things to remember here... 1. disable DHCP on the 'routers' you want to be just access points (or switches). by disabling dhcp, you are allowing your main router to do all the "routing" and assign IP addresses. 2. DO NOT use the WAN port on the 'routers' you want to be access points (or switches)'. Connect everything (link to router and link to computers) via the 4-port 'hub' on the back.

Needed to extend wireless and wired
- I have a Belkin router connected to cable modem. I also have a dedicated repeater going to my elderly in-laws house next door. In addition, I have added a second router as a gateway to handle network traffic to a ROKU / TV since this is all I use for entertainment. I also wanted to extend wireless connectivity to more remote rooms of the house. However, when i connect the ROKU to the second router (Cisco E1500), the throughput is not enough to stream video data. I measured throughput with OOkla and got 25-28 Mbps when connected to the Belkin (main router) but only 3-5 Mbps when connected to the Cisco (bridge). This also prevented video from displaying, only sound, so now I'm not sure if there is a problem with the Cisco router or with my setup... .

Connecting two modems
- I have two wireless modems that come with Internet. They are on two separate data plans. With two routers I can combine, bridge or VPN them and still keep Wi-fi in my home.

Second router for printer server
- I have an Ethernet print server and want to connect it to a additional wireless router to act as a wireless print server... .

ISP supplied router's Wi-Fi didn't work
- I added a separate router strictly for WiFi traffic, since the WiFi on the Frontier Communications modem/router kept dying. All wired devices are still connected to the Frontier device which connects to the WAN.

A triple router config
- I have 3 routers going. One for my brothers and parents devices. One for me alone, and one for my older PSP.

Separate N and G, common subnet
- I've got 2 routers on my network. An old 54 Mbps and a 300 Mbps router. The 300mbps router is connected to the Internet and set to reject any device slower then 150mbps. The 54mbps is in bridged mode, firewall turned off. They both have a different SSID. The 54mbps is in the same subnet, so it all works together as one network. 54mpbs is on channel 11, and 300mbps on channel 4 and 9 (downstairs neighbor is on channel 1, so this keeps everything separated with minimal interference). Now I have a router for slow devices and one for the faster devices. The slower ones don't slow the faster ones down, but being in the same subnet everything can talk to each other. Best of both worlds!

Can't reach config page of other router
- I have a ADSL2+Router from iBall and a wireless router from Netgear. What i want to do is to connect the wireless router to the wired modem. But the problem is that while configuring the router i get the configuration page of the old modem+router, that is iBall, instead of the new Netgear... .

Redundancy and high availability
- I have a mult-ihomed setup where i introduce 4 circuits to the UTM/firewall (router 1) where i secure my traffic, bond 2 circuits to a data center, and load balance my up-links. then finally traffic passes to my LAN routers (router 2, router 3) where I have failover-enabled redundant access to my physical network.

Deciding between two models
- I need to configure an older D-Link 4100 router that was used for cable modem, but now I have a Clearwire from this ISP, a device called Clear Hub Express which shows all password, SSID and ability to change all settings once someone hacks this hub. I keep seeing my neighbors' connections turning off or on when I disable my network connections. I suspect unauthorised usage, but there is no way to block them even after un-checking the 'connect automatically' option. If this model is not feasible, I'm considering a Linksys wireless router but have no clue if this will also work as an extra connection barrier from my computers to the hub.

Second router for isolated test lab
- I have an isolated virtual test lab to assist with IT learning. I don't want my work to interfere with the home network, so I have it running on a different subnet under a virtual router (a VM running DD-WRT).

No, I don't want a switch
- Traffic is isolated on a switch and will not "route" to other devices on the LAN. Having gotten that out of the way, I need that second router to control network access. There is a limit on a single router to the number of "allowed" MAC addresses. Of course, you can skip that and forsake security, but that's not my cup of locked-down tea.

- I use 2 routers. 1 is 5 Ghz for our phones and tablets the second is 2.4 Ghz for wireless printers and other network devices that don't support 5 Ghz

Too many devices!
- I have many devices requiring both a wired and wireless connection. I would like to set up a router between the modem and a wireless router to give me more ports... .

Multiple routers and switches
- I have about 20 devices in the house with 7 people. I use WAP devices that provide a connection to the AT&T router. On each WAP I connect the LAN side to another router or switch. On my server's side I have a Cisco 4-port gigabit router connected WAN port to a D-link WAP that connects to the AT&T router. The Cisco ports then go to 3 gigabit switches, which all my computers and gear are all CAT6 wired to. One of the Cisco ports goes to a Belkin N750 WAP, and it has another 4 gigabit ports. I connect my tablets and phones via Wifi through the Belkin. I have a small server farm, so I needed to branch my network out like this. Using the firewall of the Cisco and the Belkin I can tell you that unless a port is forwarded in the AT&T and the Cisco there's no way to reach my isolated LAN setup. I run Web servers and other services and never had my systems compromised. It's also incredibly fast. LAN side access at gigabit is nice. Also run DLNA servers for in-house gear so for multimedia - its really nice.
