Yes. You can add another router to home network. We understand 2 different scenarios where this is encountered. This is either used to extend your home wifi or setup dual internet connection with two routers.
Can I add another router to home network to extend wifi range
There are two ways to do this. You can either use an additional wireless router and connect it to the main router or you could use mesh routers.
Mesh routers are the best way to achieve the solution. With a mesh system , the number of routers you add is not restricted to one. You can add routers based on your requirements.
For example, let us assume a scenario where wifi has to be provided to a home with coverage of 5000 sqft. Instead of adding an additional router, you could look at purchasing a Mesh router.
The NETGEAR Orbi Whole Home Tri-band Mesh WiFi 6 System (RBK852) is a good choice for a wifi router which can provide wifi coverage to 5000 sqft.
The router comes in a pack of 2 and 3. You can purchase it based on your requirements.

Can I add another router to home network to support multiple internet
This is a deployment scenario where you have two internet connections from different ISP, but only home network should be available.
When two different routers from two differenr Internet service provider is available, you will have two networks. To avoid this, a multi WAN router is required. When a multi wan router is used, the two routers can be connected to it and used at the same time.
The TP-Link ER605 | Multi-WAN Wired VPN Router is a good choice for multi wan router. The router has multiple WAN interfaces to which the routers from the different ISP can be connected.
Can having two routers cause problems
No. It will not cause any problems. In a mesh router setup, you can have multiple routers. Also when you have muttiple internet connection, you can use two routers simultaneously which would not create any problems.
Does adding a second router slow down internet speed
No. It does not slow down internet speed. Having two routers in a mesh enviornment and dual wan connection would help achieve efficient internet speed.
