Improving Wi-Fi performance in your home
Dual Band Wi-Fi
Most routers and modem/routers that are sold nowadays are what is known as dual band. This means that they emit both a 2.4GHz & a 5GHz wireless signal. The 2.4GHz Wi-Fi has a longer wave length which enables the signal to travel further, it does however have issues with interference, which can cause what looks like slow speed and even dropouts if the issue is bad enough. The 5GHz Wi-Fi has a shorter wave length and thus will not travel as far as the 2.4GHz as well as having issues with going through dense objects, such as a brick wall or concrete slab. The 5GHz Wi-Fi however, does not have anywhere near the issues with interference as the 2.4GHz. If you are further away from your router, trying to use the 2.4GHz Wi-Fi. If you do notice any issues with speed over the 2.4GHz Wi-Fi, check out our interference guide here.
If your router or modem/router has external antenna that is very helpful for increasing Wi-Fi coverage. The way they work however, is if your antenna is pointing vertically, the signal will be emitted horizontally. If you live in a single storey premises, having the antenna point vertically is the best recommendation. If you live in a two storey dwelling, it may be a good idea to point some of the antenna horizontally, so the signal will be emitted vertically and cover upstairs better than if they were all pointing horizontally.
The placement of your router or modem/router within your house will also have a big part to play in getting good Wi-Fi coverage. It is often the case where you will not be able to reposition your router or modem/router, based on where your NBN Connection Box is installed. If you are able to move it however, it's best to place it as centrally in the premises as possible. If you live in a large or two storey premises you should also take in to account the router or modem/router you purchase. As Wi-Fi does have limitations with the distance the actual signal can travel, as well as often having issues passing through obstacles like brick walls and concrete floors. Mesh Wi-Fi systems are often a good solution in this case to cover your entire home.
