When to use 2.4GHz & 5GHz?

What’s the difference between 2.4GHz & 5GHz wifi networks I see when connecting to the wifi?

Your UBB router that is used with our wireless broadband, 4G broadband, and fibre broadband, uses radio frequencies to provide your cell phones, laptops, TVs, and more with a wifi connection. These frequencies are split into the 2.4GHz band and 5GHz band which you will see after your wifi name when connecting. They both come with pros and cons! So read below for which one may suit you best.

But what one should you connect to?

Well, it depends! A 2.4GHz connection travels farther at lower speeds, while 5 GHz frequencies provide faster speeds at a shorter range. Whether you choose 2.4GHz or 5GHz will depend on where and how you use your WiFi connection most.

A lot of electronic devices and appliances use the 2.4GHz frequency, including microwaves, baby monitors, and garage door openers. If you have many of these in your home, or if you live in apartments or condos surrounded by other people, that 2.4GHz band is likely to be congested, which can damage speed and signal quality.

When to use 5GHz?

If you’re located near the router, and by close, we mean in the same room. The 5GHz frequency is great for fast speeds. It’s great for online gaming and video conferencing. If you’re near the router use this frequency. Ensure all your devices are not on this frequency though as it tends to be interfered with easier.

When to use 2.4GHz?

As the 2.4GHz frequency travels further but slower this wifi frequency is much better when you are further away from the router. It can penetrate solid objects like walls far better than the 5ghz frequency. Now we say the 2.4ghz is slower but it’s definitely not that noticeable at all when surfing the web or streaming on Netflix.

What connection is better than 2.4GHz & 5GHz combined?

Using an ethernet cable directly to the device like tv or computer! A wired connection is always faster and more stable than wifi connection. So whenever it’s possible connect your device directly to the router! But in saying that its not always possible.
