If you’re looking to bolster your home wi-fi network, an aptly placed wi-fi extender can get the job done by linking up with your router to provide extra coverage. Wi-fi extenders are typically designed to work with routers of all types, and there are a number of options available.
Also sometimes referred to as wi-fi boosters and range extenders, wi-fi extenders pick up a router’s wi-fi signal and then repeat it. Working in tandem with the router, it expands the scope of a home network’s wi-fi coverage into hard-to-reach places.
It’s a potentially simple solution for households experiencing wi-fi woes. However, before buying one, take the time to identify the causes of any network issues you are experiencing.
When to use a wi-fi extender?
A wi-fi extender may be just what you need to help expand your home wi-fi network’s coverage. However it’s worthwhile weighing up a number of factors before determining the best path forward for your household.
Keep in mind that the demands on wi-fi networks are growing. A greater range of devices are seeking to connect, and services – such as HD video streaming and online gaming – are increasingly data hungry.
If you are experiencing network issues, wi-fi performance can be impacted by:
- Router – if you’re using an older model router, it might simply not be up to the job. Also, it’s a potentially simple solution, but is your router positioned where it will provide the best coverage?
- Ethernet ports – most routers come with Ethernet ports. If you’re not using these ports for wired connections to devices with high data usage, such as smart TVs, this could be creating a greater burden on your wi-fi network.
- Wireless bands – many routers utilise the 2.4GHz and 5GHz bands. (The 2.4GHz band offers better range and the 5GHz band greater speed.) However, if all of your devices are connecting on the one band, it could be creating network congestion.
- Devices – as with routers, if you’re using older devices they simply may not be capable of providing the speeds you require. For instance, older devices may only be able to connect to the 2.4GHz band.
- Retailer – is the problem with your broadband provider? It’s worthwhile getting in touch with your provider if you’re experiencing consistently lower speeds than your plan’s advertised speeds.
A good way to get a gauge on the types of speeds your household is receiving is to connect a device (such as a laptop) directly to your router via Ethernet and to run a speed test. Next connect wirelessly and conduct speed tests in different areas of your household.
This will demonstrate the difference in speed between your wired and wireless connections. It will also help you check how your wi-fi network is performing in different areas of your home.
Strong wi-fi network performance is dependent on a range of factors. When seeking to utilise a wi-fi extender, it’s important to keep in mind that it will only be as good as the wider network it’s part of.
How does a wi-fi extender work?
Always carefully consider where you position a wi-fi extender. It should be placed roughly halfway between your router and the area in which you are seeking to boost wi-fi coverage. Of course, you’ll need to be able to plug it into the mains power supply.
It may be a case of trial and error in seeking out an ideal spot. But many wi-fi extenders are designed to help with this process, incorporating indicators that guide users to optimise performance.
It’s also important to keep in mind that wi-fi extenders are only capable of rebroadcasting a wireless signal at the same strength at which it’s received. A full-strength signal will be rebroadcast at full strength, and weaker signals at weaker strengths.
Wi-Fi extender features to keep in mind:
- Wi-fi standard – refers to wireless performance capability. The wi-fi 5 standard (also referred to as 802.11ac) is commonly used. Wi-fi 6 is the most recently introduced standard. Look to match the wireless standard of your router with your wi-fi extender.
- Bands – as with routers, wi-fi extenders commonly operate on two separate wireless bands: 2.4GHz and 5GHz band. Dual-band devices provide greater connection options and capacity to manage a network.
- Speed – is measured in mbps. Wi-fi extenders often advertise the total mbps delivered across both the 2.4GHz and 5GHz bands. So make sure you check the total speed and the speeds delivered across each band separately.
- Set-up – many wi-fi extenders are designed to plug-and-play, allowing for simple pairing with a router. Some manufacturers also offer apps to assist with the process.
- Security – different wireless protocols, such as WPA and WPA2, provide varying levels of security.
- Design – wi-fi extenders are typically compact, designed to plug directly into power points or to be positioned on a flat surface, such as a bookshelf or desk.
Also keep in mind that wi-fi extenders create a separate wi-fi connection. This is often displayed in your network name list as the router network name with _EXT at the end. If you are moving around your house, accessing internet via a mobile device, you may need to switch between the different connections.
This could potentially cause delays when disconnecting and then reconnecting. However, if an extender is intended to provide coverage for stationary devices in different areas of your household, this will not present an issue.
There are a range of wi-fi extenders available at varying price points. So always shop around and weigh up the respective features on offer and how they fit your needs.
