Is 5GHz is always better than 2.4GHz ?

Using 5GHz can improve your WiFi signal, but it’s not always applicable or the better option. Using 5GHz is great for local transfer speeds, and provides both reduced network congestion and faster throughput in certain scenarios. However, the shorter radio waves mean less range than with 2.4Ghz. A 5GHz signal also won’t penetrate through walls, whereas a 2.4GHz signal can (depending on wall composition).

In addition, the 2.4GHz band works better than it has in the past because of band-steering making it less congested. Most routers and access points are now dual-band or even tri-band, which means your devices can utilise the best band available. If you’re still using a single band router, it might be time for an upgrade! If you need any help with choosing the right router, please call one of our experts on the number below.

WiFi is unreliable and even the best connections can drop unexpectedly

With older routers and access points, reliability is an issue. In the last few years, however, there have been huge leaps in reliability, speed, and intelligent technologies such as the aforementioned MU-MIMO, and QAM (quadrature amplitude modulation). These days, WiFi is seen as a must-have, not a luxury. Even if you live in a home with thick walls, reflective surfaces, many storeys, and other obstacles, there are still things that can be done to improve your WiFi coverage.

The further away from a router you are, the worse the WiFi will be?

As a general rule, if you double the distance between the router and client device (mobile, laptop etc.), throughput decreases by one-third of its original strength. This is further affected by objects that obstruct the signal, such as walls. The key to great connectivity is to place your router in an optimal location so that all or most of your home is covered. Adding access points, or a mesh router set-up, to spread the signal further is also an excellent option.
