Asus AiMesh is a technology designed to provide a mesh network in your home using a combination of new and existing hardware. One advantage of this method is that you don't have to buy a collection of often expensive mesh routers and nodes at once to set up a mesh network.

This could lead to cost savings (at least in the short term) and potentially a more impressive feature set, given the nature of some Asus routers.

AiMesh is Asus’ technology for building a mesh network of routers without having to buy a specific collection of mesh routers for the job. It makes it easy to upgrade your existing router or buy an additional router and use the combination of that new router and your current Asus router to build a mesh network.

Mesh networks have many advantages, especially in larger, more spread-out homes with lots of interfering walls. An AiMesh-powered Wi-Fi network can give you a smoother, clearer Wi-Fi signal throughout your home than a single router can provide alone.
