5 GHz Wi-Fi Extenders and Range Boosters

Usually 2.4 GHz travels farther and penetrates obstacles better, while 5 GHz can offer higher capacity over shorter distances. Building materials and interference affect both.

The extender may support a 2.4 GHz connection, but a 5 GHz-only device cannot repeat a band the router does not provide. Check its supported bands and modes.

Use the band that provides the better balance of link quality and capacity at the extender’s location. A weak 5 GHz backhaul can perform worse than a solid 2.4 GHz link.

It means the product supports both 2.4 GHz and 5 GHz Wi-Fi. It does not by itself tell you how the extender allocates those bands between router and client links.
