2.4GHz or 5GHz, what?

If you own a newer wireless modem or router you may be faced with a choice.

When you bring up the list of available WiFi networks in your home you may see a variety of options, how do you know which one to pick?

Don’t fret, the choice is pretty easy if you know what to look out for.


First, start by identifying which of the options belong to your network. Oftentimes your modem or router (whichever broadcasts your WiFi) will have a sticker on the bottom or side of the unit with the name of the network.

Second, once you’ve identified which network belongs to you, you may notice there are two similar but slightly different options: 2.4 or 5.

The two numbers at the end of your network name refer to the gigahertz in that band. The WiFi broadcasting devices that uses these two bands are called dual-band and offer you the ability to switch between two network bands depending on the device you are using and where you are using it.

The 2.4GHz band is designed for devices that may travel away from the WiFi network and require a longer range. The speed for these devices will be slower, but the signal can travel further.

The 5GHz band is designed for a shorter range but the network is faster.

Let’s say you have your WiFi hub in your living room. The TV in your living room is a SMART TV and connects to your network via WiFi. You would want that on the 5GHz band. The TV is stationary, close to your WiFi signal, and could use a boost in speed. Your daughter has an ipad and uses it in the upstairs loft. She likes to walk around with it and fire small tubby birds at seasick pigs. You would probably want her device to be connected to the 2.4GHz band.

Deciding which band to use goes a bit deeper with the strength of your network, the location of your devices, and if you have any relay hubs or signal boosters throughout your home. But the rule of thumb is: if the device is close to the signal and is stationary use the 5GHz band, and if the device moves around use the 2.4GHz.
