WiFi Range: What is the typical distance of a WiFi signal?

WiFi is a great thing — it has changed the way we live and work, allowing us to connect to the internet without being restricted to one room in the house with a cable connection. But have you ever had moments when you take your laptop to another room, or maybe even to the backyard so you can work and enjoy the sunshine, only to find the WiFi has disappeared?

While WiFi might be convenient, there is a limit to how far it can reach, not to mention that there are things that can impact the signal and cause it to drop off. In this guide, we’ll take you through the basics of WiFi and why you might be experiencing a weak or short signal.

How far does WiFi reach?

WiFi uses frequency bands to deliver signal, and these days most modems will likely use 2.4Ghz and 5.0Ghz bands. The 2.4Ghz band can be stretched further — potentially reaching up to around 46m indoors — while the 5.0Ghz band can only reach around half of this distance, but will most likely deliver faster speeds over the shorter signal distance.

The 2.4Ghz WiFi band is generally the more ‘hardy’ of the two, but slower. 5.0Ghz bands are more susceptible to obstructions and appliance interference, and by the time this reaches the bedroom or backyard, signal can be patchy at best and drop outs can occur. But close up, 5.0Ghz can be the way to go to get faster speeds.

Placing a dual-band router (which supports both 2.4Ghz and 5Ghz bands) near technology that can make the most out of the faster 5.0Ghz band – such as gaming consoles and PCs – and leaving 2.4Ghz bands for phones and tablets, could make the most of your home WiFi.

The technology used for the routers can also impact how far your WiFi can reach. Modern routers with 802.11n or 802.11ac classifications on 2.4Ghz bands can theoretically only reach about 25m indoors. While older, slower, routers on the 802.11a classification generally might have a better range, but at the expense of speed.

If you’re experiencing slow speeds and drop outs and your modem is rather old, it might be worth considering a new modem. The WiFi technology in devices, such as computers, can also have an impact on how solid the performance of the WiFi connection is, so keep this in mind if you have unreliable WiFi.

What can obstruct or impact a WiFi signal?

We’ve established that WiFi signal distance between the router and the device using the WiFi can have an impact on performance, however there are other factors that can also impede how well your WiFi performs.

The size of your home obviously plays a big part. Larger houses may have a harder time with reaching more corners of the house due to the size and distance from the router — and more chances of the signal being obstructed — compared to smaller homes or apartments where you’re going to be closer to the router.

WiFi signal can also be impacted by the following:

  • Walls and obstructions
  • Weather
  • Appliances
  • Antennas and direction

Walls and other obstructions can block the signal and prevent WiFi from reaching certain parts of the home, especially if the router is placed near a wall. Ensure your router is in a fairly unobstructed part of the home and in a position as central to WiFi-connected devices as possible.

Weather can also have an impact, but mostly using WiFi outside. Electrical storms can interfere with the electromagnetic signals that WiFi emits and this can wreak havoc on wireless networks. Likewise, appliances, especially microwaves, can affect the WiFi signal. Because microwaves emit radio signal, which can interfere with WiFi network range, it’s best to keep your router away from appliances.

The direction of your device can also impact how strong a signal you have — holding your smartphone away from the router can make your signal drop a bar or two, but a directional antenna can help to reduce this.

Overall, it’s best to keep your router away from walls and obstructions, and in a very central place, especially where you mostly use the internet in the home. If you frequently stream on your TV or play online games, you may wish to put your router near the TV or computer/console. The living room is most likely going to be the area where you use your WiFi the most and a more central and open area of the home, so it makes sense to put your router there.

How can I improve my WiFi range?

While keeping your router in a fairly central location or near where devices that use the WiFi are — such as the living room — can improve WiFi performance, there are some products that can improve your WiFi range or boost your WiFi signal.

  • WiFi extender or booster
  • Powerline adaptors

A WiFi extender (also referred to as a WiFi repeater or WiFi booster) can be plugged into an electrical socket, which then picks up your WiFi signal and re-transmits the signal throughout the home. They can cost as little as around $40 and up to the hundreds, with the more expensive devices delivering speeds up to 2.2Gbps. However, boosters can severely affect latency or ‘ping’ scores, which can be bad news for gamers who need millisecond-precise responsiveness from their WiFi.

Powerline adaptors are purchased as a pair and are plugged into two power points in different ends of the home, meaning that WiFi can be transmitted across powerlines. Adaptors are usually a little bit more expensive and can often cost over $100, but are arguably more effective than boosters. In order for these adaptors to work, they need to be on the same powerline, and considering homes can have multiple lines, you might want to check this before you purchase an adaptor that won’t work for your home.

What is long range WiFi?

If you’re living in a large home or need WiFi out in the backyard, a long range WiFi router may be ideal. However, the catch is that speeds can suffer as a result.

TP Link is a wireless modem brand that offers two ‘high powered’ modems – the TL-WR941HP and the TL-WR841HP. TP Link claims its high-powered modems are capable of covering up to 10,000m² – or one hectare – of range.

These high-powered models support between 300-450Mbps wireless speeds, and TP Link claims the 9dBi high-gain antennas are capable of cutting through walls and obstacles to deliver more powerful signals even in far reaches of the home.

However, there is pretty much always a compromise. Even with high-powered modems, speeds can still suffer. The modems mentioned above are not capable of gigabit speeds and their speeds may still suffer the further you are away from the modem. However, these routers are generally at the cheaper end of the scale, so they may be worth a go.

Is a good WiFi range really important?

If you frequently experience internet connection drop outs, rather than blaming your internet provider, you might want to first check if it’s an issue with your internet router range. Consider how close your device is to the router, if there are any obstacles and look at how strong the WiFi signal is. If the signal is down to a couple of bars when you experience slow internet, you may need to look into optimising your WiFi range.

Following the tips in this guide may help you to get to the bottom of why you are having issues with your WiFi connections; however, if you are still having problems despite minimising obstructions and disruptions to the signal, there might be another issue. When troubleshooting, make sure you also test connections on different devices and at different locations within the home to ensure it’s not an issue with the device itself.

You might need to look into boosters or adaptors, but also consider the age of your router as another reason for slow performance and whether you might need to upgrade. If it’s clear that the issue isn’t with your WiFi signal distance or router, you may need to have a chat to your internet provider and see if there are any issues with your home’s internet connection.

Even if your home WiFi performance is fairly decent and consistent, it’s still best practice to ensure you place your WiFi router in an ideal location — away from appliances and walls, and closer to where the internet is mostly used, such as the living room, study or bedroom. WiFi range may sound complicated, but following a few simple steps can mean the difference between slow video buffering or enjoying your favourite show in glorious high definition.
