The advantages of a wireless network do come with some additional considerations that are absent in a wired network configuration. One of the most important factors that need to be addressed when setting up a wireless network is the range of the Wi-Fi signal.

The ability of the signal to reach and adequately serve your users is the reason that a WiFi network was constructed in the first place. If the signal is weak or non-existent in portions of your intended coverage area your WiFi network needs to be tweaked. One of the primary ways to address this problem is to boost the WiFi signal.

How to Extend WiFi Range

When faced with the need to extend the range of your WiFi network there are a number of options from which to choose. Some are simple and do not involve the purchase of any additional equipment. In other cases, you may need to make a financial investment to provide the WiFi range that your users require.

Step 1

Find a Better Place for Your Router

Even the best WiFi router available won’t be able to provide satisfactory coverage if it’s positioned poorly. As you may know, the WiFi signal is affected by all kinds of interference, including walls, furniture, electronic appliances, and other wireless devices. While it may seem convenient to hide the router inside a cabinet, the strength of your signal will suffer considerably.

Simply finding a new location for your wireless router can have a dramatic impact on your WiFi signal for a variety of reasons. You should strive for a central location that is free from physical obstructions like walls and doors if possible. Don’t keep your router in a closet or a desk drawer if you hope to realize its true potential signals range.

Optimize the placement of your router

Try to place it as high as possible, with a line of sight to all devices that will be connected to it. While this is not always totally feasible, getting as close as you can to this goal will help you extend the range of your WiFi router.

You can easily find a better place for your router to extend your WiFi range using a WiFi analyzer and heat mapping tool like NetSpot. With this useful software application, you can visualize the strength of your wireless signal on a map and easily see all areas of signal weakness.

Step 2

Update your router’s firmware

Keeping your device’s firmware current can help you obtain the best WiFi signal that the router can provide. Just like computers and smartphones, routers receive updates from their manufacturers, and it’s important that you install them as soon as possible to keep your router secure and in good working order.

Depending on the manufacturer there are different methods that need to be used to update your firmware. The good news is that most routers make the update process easy, and you should be able to accomplish it directly from the administrator interface. Some routers even have a companion app for Android and iOS mobile devices, allowing you to take care of firmware updates with a simple tap.

Keep Router Updated

And some routers can be configured to automatically update the firmware. If your router is in that category, it is strongly recommended that you take advantage of the auto updates. Even if the update doesn’t solve your problems with insufficient WiFi range, you can at least be happy, knowing that your router is more secure.

Step 3

Use the 5 GHz Band

Dual frequency routers offer you the choice of 5.0GHz and 2.4GHz bands. You might find that switching to the 5.0GHz band improves your WiFi range as it will incur less interference from other electronic devices since the frequency is used less often.

Switch to a Different WiFi band

Because of its higher frequency, the 5 GHz band is able to offer superior speeds and, in some situations, better signal strength. Its biggest downside is its shorter range and inferior ability to penetrate solid objects.

However, if you live in a densely populated area, surrounded by WiFi networks broadcasting on 2.4 GHz, the 5 GHz band is an easy choice.

To learn more about nearby WiFi networks and the bands they broadcast on, you can use NetSpot’s Inspector Mode, which quickly gathers a wealth of information about all WiFi networks within reach and presents it in the form of an interactive table.

NetSpot Inspector mode
Step 4

Change Your WiFi Channel

Just like walkie-talkies, all WiFi routers broadcast on a certain channel. In the 2.4 GHz band, there are 11 channels, but only channels 1, 6, and 11 are spaced far enough from one another to not overlap.

The remaining channels can be used, but they are more likely to experience interference resulting in slowdowns, particularly in heavy use, so it’s important to use the least congested non-overlapping channel available in the 2.4 GHz band.

Fortunately, far more channels are available in the 5 GHz (45 channels) and 6 GHz bands (seven 160 MHz, fourteen 80 MHz, twenty-nine 40 MHz, and fifty-nine 20 MHz channels). As a result, issues with their overlapping are much less common.

Switch Different Channel

In any case, a WiFi analyzer such as NetSpot can survey your own network as well as other networks whose signals may overlap with yours and make it easy to determine which channel you should use.

Once you know which channel is the most suitable, you can sign in to your router’s administrator interface and configure it to use it. Your router will then restart to apply the new settings.

Step 5

Get a Better Antenna

If you have a router with a replaceable external antenna, you can easily improve its performance by getting a better one. The gain of WiFi antennas is indicated in dBi (antenna gain in dB above an isotropic radiator). Many budget routers come with a small antenna with just 2 dBi, and replacing such antenna with a high-gain alternative is guaranteed to provide a significant boost in WiFi range.

Get Strong Antenna

To reinforce a particular area of signal weakness, you can point a directional antenna toward it, but you need to keep in mind that other directions may suffer. That said, most router antennas tend to be omnidirectional.

Step 6

Using a WiFi extender

In a similar manner to a second router, a WiFi extender or booster also takes the original signal and repeats it to extend its reach. WiFi extenders are also available without any ingress protection for use indoors. Such WiFi extenders are usually considerably less expensive than their outdoor counterparts, and they’re just as easy to install.

Buy Repeater/Extender

They come in a variety of styles including extenders that simply plug into a nearby electrical wall outlet and can solve the problems of an inadequate WiFi range. Regardless of which type you select, make sure to use NetSpot to determine the optimal placement for your WiFi extender so that it extends your WiFi range as much as possible.

Step 7

Employing a mesh network

If your budget allows it, then we recommend you extend the WiFi in your house by replacing your existing router with a mesh system to create a so-called mesh network.

A mesh network is made up of two or more WiFi access points, typically called nodes, which together blanket a large area with seamless WiFi coverage. By setting up a mesh network in your house, you can gain the ability to roam with your devices from room to room uninterrupted by connection drops and slowdowns.

Set Up Mesh WiFi

While often deployed on a large scale by enterprise customers, mesh systems are also readily available to home users, and their installation is so easy that anyone can do it. Here’s how to set up a mesh system in a nutshell:

  1. Buy a mesh system that can cover your entire house.

That’s how easy it is to set up a mesh system!

Step 8

Upgrade Your Router

Upgrading your router can significantly enhance the performance and range of your Wi-Fi network, especially if your current router is several years old. Modern routers incorporate the latest technologies and standards, such as 802.11ac or Wi-Fi 6, which offer improved speeds, better range, and more efficient handling of multiple devices simultaneously.

Older routers may not efficiently manage the bandwidth demands of today’s high-definition streaming, online gaming, and smart home devices. They often operate on overcrowded frequencies, leading to interference and reduced performance. In contrast, newer routers can operate on multiple frequency bands (dual-band or tri-band), offering dedicated channels for different types of devices, reducing interference, and ensuring smoother connectivity.

Additionally, contemporary routers come with advanced features such as beamforming and MU-MIMO (Multi-User, Multiple Input, Multiple Output). Beamforming enables the router to focus signals directly towards individual devices, avoiding the scattergun approach of broadcasting signals indiscriminately in every direction, thereby improving signal strength and range. MU-MIMO allows the router to simultaneously interact with several devices at once, significantly boosting network efficiency and capacity.

The physical design of newer routers often includes more or high-gain antennas, which can further extend the Wi-Fi coverage area. Furthermore, the latest routers come with enhanced security protocols, providing better protection against unauthorized access and cyber threats.

Buy a new WiFi Router

Investing in a new router can be a straightforward and effective way to extend your Wi-Fi range, especially if you’re experiencing connectivity issues, slow speeds, or have a growing number of Wi-Fi-enabled devices in your home. It represents a critical step towards building a more reliable and faster home network capable of handling today’s digital demands.

How to Extend WiFi Range with Another Router?

If you have exhausted the free methods of extending your WiFi range to no avail it might be time to consider purchasing some additional equipment in order to improve your WiFi coverage. There are a number of different ways you can do this.

Before you purchase another router and set it up, we highly recommend you check your WiFi coverage using NetSpot so that you have reliable data that you can use to determine whether the change you made produced a desirable result.

Step 1

How to Extend WiFi Range with Another Router with Cable?

If your current router has a free Ethernet port, you can simply connect another router to it with an Ethernet cable and place the new router anywhere you want. Since the maximum recommended length for Cat5e cable is around 100 meters, you can position the new router pretty much anywhere you want.

Using another router with Cable

Because your existing router is almost guaranteed to support and use DHCP, a network management protocol that dynamically assigns an IP address and other network configuration parameters to each device on a network, you can simply connect the new router to it and use it as an access point — no additional configuration required.

Basically, you are using the second router to catch the WiFi signal and push it to previously unreachable parts of your home or office.

Step 2

How to Extend WiFi Range with Another Router without Cable?

Connecting two routers with an Ethernet cable can be a lot of work — not to mention that high-quality Ethernet cables are not exactly cheap. At the cost of some performance, you can extend WiFi range with another router without a cable by setting up the new router as a wireless repeater.

Using another router without Cable

The job of a wireless repeater is simple: rebroadcast the signal from your main router. Unfortunately, not all WiFi routers can work as repeaters, so do your research and select one that can. Alternatively, you can replace the stock firmware with DD-WRT, an alternative router firmware with plenty of useful features.

How to Extend Wi-Fi Range Outside?

Extending WiFi range outside is relatively easy, provided you have the right equipment for the job. Because a regular WiFi router wouldn’t be able to survive the exposure to the elements, you need a device that’s meant to be left outside regardless of whether its freezing or raining. We recommend an outdoor WiFi extender, sometimes called a WiFi repeater or access point.

Extend WiFi Range Outside

Your outdoor WiFi extender of choice must have a sufficiently high ingress protection (IP) rating, and the temperature range it can withstand must cover even extreme temperatures in your area. When it comes to setting up an outdoor WiFi extender, you simply connect it to power and position it within the range of your indoor WiFi router.

Why Would You Need to Extend the Wi-Fi Range?

There are several reasons that you might want or need to extend the WiFi range that you currently are achieving.

  • Poor planning — Creating a WiFi network without adequate planning can result in poor coverage and can negatively impact your users. All users need access to a strong WiFi signal in order for your network to operate successfully. Later in this article, we will look at how a WiFi tool like NetSpot can help alleviate this type of problem.
  • New requirements — This issue can arise in a business setting where additional space is used to house new employees. Despite your best previous efforts in sizing your WiFi network correctly, you now may be faced with the problem of figuring out how to extend the WiFi range to accommodate the influx of new users.
  • Inadequate signal — You can be faced with this issue no matter if the WiFi network is used for business or simply for home use. You might have issues connecting to the WiFi from certain rooms in your home. Customers taking advantage of the free WiFi offered by your coffee shop may need to avoid certain parts of your establishment.

Predicting and Optimizing the Range of Your WiFi Network

Making use of a quality WiFi analyzer like NetSpot can help you tune your WiFi network and determine if the signal is strong enough for your intended coverage area. Let’s take a look at how to use this powerful tool both prior to installing your wireless network and using it to optimize it once it is in place.

You should conduct a site survey using the tool before you purchase any equipment for your WiFi network.
