Best Home Wi-Fi Mesh Systems -2021

wi-fi-meshWhat is the best home Wi-Fi mesh system for providing whole house Wi-Fi?

There are many reviews on the Internet comparing different brands. Some very biased and others less so.

Personally I don’t have the time to review all of the available systems on the market. My normal approach is to look at products offered by the network equipment supplier that I mainly use which is TP-link.

I then look at the features,cost and reviews before deciding.

If you are not already familiar with the concept of wireless mesh networks then take a look at mesh networks

To save you some research I’ve listed the 5 most popular and affordable mesh systems I found on Amazon USA below.

I’ve ordered them by the number of reviews which should reflect the overall popularity. All of the systems received top ratings and are in the affordable price range.

Feature Explanation

Tri Band Mesh wifi

Wi-fi operates on two frequency bands 2.5GHz and 5 Ghz. These are used by clients (laptops,tablets etc) to connect to the network. Older devices only support the 2.5GHz band.

The mesh nodes also need to communicate with each other to pass data and network traffic as shown below:


There are three possibilities for the internode connection.

  • Ethernet
  • Wi-Fi 2.5 or 5GHz shared
  • Wi-Fi 2.5 or 5GHz dedicated

When the nodes communicate using a dedicated frequency band (usually 5Ghz) this is called tri-band.

On a network with many clients this would be faster than using the shared mode where the internode connection and the client connections shares the frequency bands/channels.

Powerline Mesh wifi

Again this refers to the internode connection which uses Ethernet over Powerline connectors. This is normally faster and more reliable than using Wi-fi but slower than using an Ethernet cable.

Mesh Wi-Fi  6 System

Wi-Fi  6 is the latest Wi-Fi standard offering higher speeds and greater distances than Wi-Fi 5. The only problem is that only very new devices support it.
