Boost your Wi-Fi

[ Edited ]
    1. Use the latest Wi-Fi technology – One way to boost Wi-Fi Speed around the home or office is to make sure you are using the latest technology. Your old router might at best support 802.11N which is 54Mbps. The latest technology on offer is Wireless 802.11AC with typical home routers reaching speeds of 733Mbps depending on the antenna configurations. It is all very well having the latest space age router with 8 antenna, but don’t forget to ensure that your PC also supports 802.11AC, otherwise you will still be restricted to wireless N speeds.


    1. Find the best spot for your router – Routers might not fit in with the latest interior design décor, but slow internet irritates everyone, so find the best spot for your router. Often we just place the router where our broadband line enters the house. This might be short-sighted, as you may find that this is on one side of the house and you need access on the other side. A good place to put your router is in a central location. Some people have even found that in your roof is the best place due to the roof being an open cavity with no walls to block and bounce signal around. Also angle your antenna correctly. A good guide is to point them perpendicularly (1 up and 1 sideways). Be mindful of electric equipment near your router, as these could cause interference.


    1. Find the right channel – The frequency that Wi-Fi operates on is split into channels (virtual pipes). If you and your neighbour are both on the same channel, you are effectively sharing bandwidth on that pipe, meaning that you could be blaming your provider for slow speeds that is due to your Wi-Fi setup. What to do? If you have a smartphone, download a Wi-Fi Analyser App. These apps tell you what is in each channel (1-13) and shows you which channels are open. Log into your router, go to Wi-Fi settings and change the channel to the free channel.


    1. Have better Wi-Fi security – Leaving your router on default settings is a sure way of allowing your tech savvy neighbours to gain access to free internet (Your Internet!). For this reason, ensure that you secure your router. There are a few steps to take.
      1. Change the default router password
      2. Enable WPA encryption on your router
      3. Setup a complex passphrase (Wi-Fi password)
      4. Hide the SSID (the name you see when you switch on Wi-Fi and connect to)


    1. Limit certain bandwidth hogging applications – You might be trying to do some work and the kids are streaming YouTube in all its 4k glory. In order to get the best experience for all, limit certain of these bandwidth hogs using QOS (Quality of Service) by setting how much bandwidth is available to these protocols or applications.


    1. Use W-Fi repeaters – These days you can pick up a Wi-Fi repeater for a few hundred Rand. They are usually simple wall plug device that extends the range of your Wi-Fi in those far parts of the house. You could even use on old spare router to perform this function by using the built in WDS (Wireless Distribution System) functionality.


    1. Reboot your router periodically – Routers are electronic devices and such devices are not perfect. They are affected by heat, firmware and other issues, so it is a good idea to reboot your router every now and then.


Please add any tips you may have for others.

RE: 3


Buy a router that offers 5GHz. Most modern equipment can receive the 5GHz channel which are less congested than the 2.4GHz channels. 2.4GHz shares your cordless phones; garage door openers and microwave ovens.


Also 2.4GHz channels only have 3 non over-lapping channels (1 ,6 & 11). The 5GHz channels have 123 non over-lapping channels.


RE: 6 using range extenders are not ideal as they half your connection speed. A mesh type network is best or use extra AP (Access Points) to extend your network. However this means running multiple LAN cables from your primary router to these APs.
