While the majority of 5GHz routers are dual-band and also broadcast on 2.4GHz, there are those which are limited to the single higher frequency.

Unfortunately, most smart home devices run on 2.4GHz Wi-Fi which leaves people in a bit of a bind. We give a run down on the compatible 5GHz smart plugs available for those with these router restrictions

Update: Only the 1st Gen versions of Leviton linked below support 5GHz. The newer 2nd Gen versions only work on the 2.4GHz band.

Range & Penetration

The 2.4GHz wi-fi radio frequency provides a longer distance/range than 5GHz however it does so at a cost. What sets the two apart is that 5GHz operates on a higher frequency which equates to a higher speed. 

That is why 5GHz is ideal for video streaming while the simple On/Off style commands of smart home devices can easily be catered for over 2.4GHz.

In addition, 2.4GHz broadcasts can easily penetrate obstacles and cover farther distances, compared to 5GHz.

5GHz Routers

Most 5 GHz routers available are dual-band and have two radios; one 2.4 GHz and one 5GHz. Either both frequencies are broadcast with the same Wi-Fi network name or they could be available under slightly different network names.

If your router is restricted to just a 5GHz broadcast, then read on to see which smart plugs are compatible.

Common Questions Relating to Smart Plugs

Why Do You Need A 5 GHz Smart Plug?

The only real reason you would need a 5GHz smart plug is if your current router does not have a 2.4GHz band. And you don’t want to replace your existing router with a dual-band device.

Differences between 5ghz And 2.4 GHz

The main difference between 5GHz and 2.4GHz Wi-Fi is range and bandwidth. 2GHz Wi-Fi frequency offers a longer range than 5GHZ Wi-Fi – for example, 2.4GHz Wi-Fi is better at penetrating obstacles such as walls and floors. However, 2.4GHz has a slower speed than 5GHz. 5GHz offers speeds of up to 1,300 Mbps whilst 2.4GHz only offers between 450 and 600 Mbps.

How To Boost Signals If You Cannot Connect To Your Smart Plug?

 If you are struggling to connect to your smart plug, it may be a Wi-Fi signal connection issue. So, you want to opt for a dual-band router and utilize a 2.4GHz smart plug which offers a longer range. If that doesn’t work you can set up a wireless repeater or upgrade to a mesh Wi-Fi system to boost the signal.

    Spectrum offers routers that only allow the 5Ghz part of the router. It is a ridiculous setup. Trying to use wireless smart devices like plugs is a pain to find. I wish companies would just switch over the connecting to 5ghz already and quit staying in the past.

    The big pain with the 2.4 device is that you need to swap you phone connection from the 5G connection you are most likely on to the 2.4 connection in order to control the device.
