What Is The Difference Between 2.4 Ghz and 5 GHz?


2.4 GHz and 5 GHz

These numbers refer to two different “bands”  or 'wavelengths' that your WIFI can use for its signal. The biggest difference between the two is speed. Under ideal conditions, 2.4 GHz WIFI will support up to 450 MB or 600 MB, depending on the router. 5 GHz WIFI will support up to 1300 MB.

A big caveat is that important phrase “ideal conditions.”

More Than Just WIFI


The 2.4 GHz band is a pretty crowded place, because it’s used by more than just WIFI
Old cordless phones, garage door openers, baby monitors, and other devices tend to use the 2.4 GHz band. The longer waves used by the 2.4 GHz band are better suited to longer ranges and transmission through walls and solid objects. So it’s arguably better if you need better range on your devices or you have a lot of walls or other objects in the areas where you need coverage. However, because so many devices use the 2.4 GHz band, the resulting congestion can cause dropped connections and much slower than expected speeds.

The 5 GHz band is much less congested, which means you will likely get more stable connections. You’ll also see higher speeds. On the other hand, the shorter waves used by the 5 GHz band makes it less able to penetrate walls and solid objects. It’s also got a shorter effective range than the 2.4 GHz band.  

Connect Fibra Routers

All Fibre Optic routers supplied by Connect Fibra are dual band. This means you may see two options to connect to your WIFI. We would always recommend 5G if you are having issues and it is available. The password is identical in both cases but if you do have both options and are not connected to 5G - see pic below - your speed and service on WIFI may well be not only slower but also cut out at times due to reasons above.
