Dual Band WiFi Extenders: What to Check Before Buying

Dual-band extenders use both 2.4 GHz and 5 GHz WiFi bands. Match the model to your router and consider whether mesh roaming or a wired access point better suits your layout.

A dual band WiFi extender can connect over 2.4 GHz and 5 GHz, giving you more flexibility than a single-band repeater. A common example is the TP-Link RE200 AC750, which the Australian product page lists with both bands and an Ethernet port. NETGEAR EX3700 is another AC750 dual-band model with external antennas and an Ethernet port.

Common questions

Questions before you buy

What is a dual band WiFi range extender?

It supports wireless connections on 2.4 GHz and 5 GHz bands. The available band and speed at any point still depend on the router, client device and signal conditions.

Is NETGEAR EX3700 dual band?

Yes. NETGEAR describes the EX3700 as simultaneous dual-band WiFi on 2.4 GHz and 5 GHz, with an AC750 wireless rating and an Ethernet port.

What does AC750 mean on an extender?

AC750 is a class label for the model's maximum combined wireless link rates, not a promise of 750 Mbps internet throughput to one device. Actual performance varies with network and environment.

Do I need tri-band instead of dual-band?

Not necessarily. Tri-band can provide an additional radio for network traffic, but suitability depends on the router and model design. Compare a mesh system if you need coordinated coverage across many rooms.
