WiFi can be a fickle thing. You may be enjoying a perfectly strong WiFi signal, move just a few steps in one direction, and watch it drop to one bar.
Check out a video guide on how to boost Wi-Fi signal at home—some tips and tricks as well as how to use NetSpot to see surrounding WiFi networks and perform a WiFi site survey.The seemingly unreliable nature of WiFi networks has everything to do with the fact that there are many factors that influence their performance.
Now that you understand the top 5 factors that affect WiFi performance, it’s time to take a closer thing at some of the things you can do to improve it.
Not all places are equally suitable for your router. To start with, you want to avoid placing your router close to metal objects and appliances that emit electromagnetic waves. Metal is the top disrupter of a WiFi signal, and its presence close to a WiFi router can easily create a large dead zone.
Other materials, including glass, wood, plastics, foam, and cardboard, can also disrupt a WiFi signal but their influence of WiFi signal strength tends to less severe. Keep in mind that many buildings use metal studs (rather than 2x4 wood) for the particle board mounting, and placing your router close to them would be a bad idea. When in doubt, use a handheld stud finder or at least a stud finder app on your smartphone.
Strictly speaking, all household appliances emit electromagnetic waves to some degree, even fluorescent lightbulbs, circuit breakers, and electric razors. The biggest emitters of electromagnetic waves tend to be found in the kitchen, and they include stoves, microwave ovens, and dishwashers.
Other problematic appliances are washing machines, tumble dryers, televisions, cordless phones, and radiant heaters. If you have any of these appliances at home, keep your WiFi router as far away from them as possible to boost WiFi signal.
Ideally, you also want to keep a safe distance from electric wires. To cover an area with an even WiFi signal, you should place your WiFi router roughly in the center. You can slightly boost your wireless signal by elevating the router above the floor level.
WiFi signals radiate outward in all directions, not just horizontally. When your router is on the floor, it’s ability to emit strong signals is severely limited. For the same reason, people who live in multi-store houses should always locate a Wi-Fi router near the ceiling on the first floor. This way, even the second floor will receive consistent coverage.
If you follow the news, you’ve heard about the growing number of large-scale malware attacks that are costing businesses and individuals alike billions every year. Many of these attacks wouldn’t be possible if all routers were kept updated. Once a malware infects a router, it can steal bandwidth and spread itself across the network to other devices.
But even without a presence of a dangerous malware, routers with old firmware perform worse than routers that are properly updated.
To check if your router is running the newest firmware available:
Most WiFi routers come with small, weak antennas. It’s not that manufacturers want to save every cent they can, but powerful WiFi antennas tend to be hideously large. Compared to the antenna that came with your router, which probably is just a few inches tall and has around 4 dB gain, a 10-dB antenna can be anywhere between 10 to 15 inches tall.
But if you don’t mind the size, a new, powerful WiFi antenna is a great way how you can boost WiFi at home or office without buying a new router.
There are several different types of WiFi antennas, but the only type you need to care about is the common “rubber duck” antenna, which is an electrically short monopole antenna that consists of a springy wire in the shape of a narrow helix, sealed in a rubber or plastic jacket to protect the antenna.
Such antennas use the same RP-SMA connector, and there are many different models available on Amazon and other online stores. Some even come with a handy extension cable that allows you to place the antenna farther away from your router to achieve optimal signal distribution.
To boost WiFi signal, you need to purchase an antenna with more gain than your current one. The gain of an antenna system relative to an isotropic radiator at radio frequencies is expressed in dBi, or decibels relative to isotropic. Most home routers come with small antennas, whose gain tends to be between 4–5 dBi. Replacing such antenna with a 9 dBi antenna should provide excellent signal boost.
An encrypted, password-protected WiFi is a must in this day and age. With more people than ever relying on WiFi, the hunger for open, fast WiFi networks is real. Don’t think that your neighbors won’t use your WiFi network just because they have their own — they will.
You should encrypt your WiFi and protect it with a strong password that can’t be easily guessed. A strong password should:
If you have lots of guests, create a separate guest network and either significantly limit its range or protect it with a different password and change the password on a regular basis.
Even though they are referred to by many names, WiFi boosters, repeaters, and extenders are basically the same thing.
WiFi repeaters are relatively simple devices that take an existing signal from your WiFi router and rebroadcast it as a new network. This new network is just an extension of your main network, and all data that go through it also go through the main network.
WiFi boosters and extenders are very similar, but they also amplify the existing signal before rebroadcasting it to create a second network. Because WiFi boosters typically have greater range than WiFi repeaters, they make sense in situations where the original signal is very weak.
A good repeater or booster costs less than $100, and it can be installed in a few minutes by anyone since the installation process usually involves only the press of the WPS button. You can find a list of the top 5 WiFi boosters at the end of this article.
To achieve the best performance when using a WiFi repeater or booster, it’s a good idea to use a WiFi booster app to analyze existing WiFi coverage and determine the optimal way how to extend the existing WiFi network.
Just like lanes on the highway, there are multiple WiFi channels on which a WiFi router can broadcast. Even though most countries have six non-overlapping channels (1, 6, 11, and 14), many users leave their router set on the default channel, which is usually either Channel 1 or Channel 6.
This results in a WiFi traffic jam as too many packets are trying to drive on the same line. The solution is simple: find out which channel is occupied the least and switch to it. This can be done with the help of NetSpot, a professional and easy-to-use WiFi analysis and surveillance tool.
With a new channel selected, you need to tell your WiFi router to use it:
You can now verify that your router is broadcasting on the new channel using a WiFi network analyzer like NetSpot.
It takes just one bandwidth-hungry application or a client to make download and upload speeds come to a crawl for everyone else on the same WiFi network. Luckily, modern routers support services like QoS (Quality of Service), which allow users to prioritize certain applications over others. With QoS, your online gaming session won’t ever be interrupted again by a person watching a 1440p video on YouTube or downloading a huge Linux distribution from the Internet.
To change your router’s QoS settings:
Some routers make it very easy to configure QoS settings, while other routers are far from intuitive. When in doubt, consult the manufacturer of your router.
The newest wireless technology, IEEE 802.11ac, offers superior download and upload speeds as well as improved range compared to older WiFi technologies, such as IEEE 802.11b, g, and others. To take advantage of the latest WiFi technologies to boost home WiFi, you need to make sure that both your home router and your WiFi-enabled devices, such as smartphones and laptops, support them.
When selecting a new WiFi router with support for IEEE 802.11ac, don’t pick the most affordable model you can find. Unless your budget is very strict, it’s always worth spending extra to purchase a router with excellent range and modern features such as MU-MIMO, Quality of Service, guest networks, gigabit Ethernet ports, and replaceable external antennas.
A good router should be able to serve you well for at least five years, which is approximately how long it usually takes for a major new WiFi technology to become mainstream. Near the end of this article, we recommend five best WiFi routers from leading manufacturers, so all you need to do is pick one that fits your budget.
The 5 GHz wireless frequency provides faster data rates at shorter distances and is typically much less busy than the 2.4 GHz wireless frequency. If your router supports it, consider switching to it for an instant short-range speed boost.
How to boost your WiFi by switching your router to 5 GHz:
One downside of the 5 GHz wireless frequency is that it doesn’t penetrate solid objects nearly as well as the 2.4 GHz wireless frequency. This can be a problem in office buildings and residential areas, so it’s advisable to always use 5 GHz in conjunction with 2.4 GHz. That way, you can get the best of both worlds.
The timeless IT advice, “If it doesn’t work, try switching it on and off", also applies to WiFi routers. A simple reboot is often enough to considerably improve your WiFi speeds. A reboot clears the router’s memory and allows updates to install.
To reboot your router, either press the restart button located on the back (you may need a pointy object like a pen to get to it because many router manufacturers use recessed restart buttons) or simply disconnect the router from power and turn it on again.
If your router really starts installing an update during the reboot, be patient and don’t interrupt the update process by turning off your router. Depending on your router’s performance, the update process may take more than 10 minutes.
If you’ve tried the 10 above-described tips for improving wireless internet performance without any success, then it’s time to shift your focus from your WiFi and measure wired internet performance. To do that, you need an Ethernet cable and a laptop or desktop computer with an Ethernet port.
We recommend you repeat the wired internet performance test several times, preferably at different times of the day. Once you’re certain that your internet service provider is to blame, send them the results of your tests and ask them to fix the problem. If they fail to do so, then it’s probably time to switch to a different internet service provider because even the best tips on how to increase WiFi signal won’t help you.
Sometimes, a single router — no matter how capable — can’t reliably cover the entire living space with a strong WiFi signal. In such cases, it’s best to set up a mesh WiFi system, which consists of the main router and multiple satellite units that together provide seamless WiFi coverage.
Some of the most popular mesh WiFi systems available today come from Asus, Eero, Orbi, and Google, and we offer some recommendations later in this article. What’s great about mesh WiFi systems in general is that you can expand them depending on your needs. This means that you can start with just one main router and one satellite unit and upgrade only if your WiFi is still not performing up to your expectations.
The Domain Name System (DNS) is responsible for converting domain names (such as www.google.com) into IP addresses (64.233.160.0). By default, your modem is most likely configured to use your internet service provider’s DNS server, whose performance may not be the best.
The good news is that most modems let you change your DNS address, which is often the easiest way how to boost WiFi performance. There are many public DNS servers you can choose from, including Google’s DNS server (8.8.8.8) or Cloudflare’s DNS server (1.1.1.1).
To help you pick the best DNS server, we recommend you download and run Domain Name Speed Benchmark. This free Windows application offers features designed to enable serious DNS performance investigation, and you can use it to find the fastest DNS server in your area with just a few clicks:
Once you’ve picked the best DNS server available, you need to go to your modem’s settings and replace the default DNS address with the DNS address of the new server.
It’s easy to underestimate just how many devices these days connect to the internet via WiFi. From computers and mobile phones to various smart home products and appliances, these WiFi-connected devices consume a substantial amount of bandwidth, and not all internet plans can provide it.
If you’ve been paying for the same internet plan for the last 10 years, then you should look at what other options are available and considering upgrading. You might even be able to save some money since the prices of fast internet plans have gone down substantially since the early days of broadband internet.
Last but not least, consider contacting your internet service provider and asking for help. If the ISP truly cares about their customers, they will help you remotely diagnose your WiFi performance issues or even send over a technician to measure your WiFi signal strength and help you boost wireless signal.
The purpose of WiFi boosters is to extend an existing WiFi signal to areas where it can’t reach. Most WiFi boosters are designed to be plug and play, making it possible for anyone to install them on their own to enjoy a strong and reliable WiFi signal everywhere.
When selecting a WiFi booster, make sure you have at least a rough idea of how large is the area that you want to cover. You can use a network analyzer like NetSpot to create a signal heatmap of your space. Then you need to set a budget and evaluate the potential candidates based on their features.
To make the selection process easier for you, we selected the top 5 best WiFi boosters according professional reviews and real users alike.
The Netgear Nighthawk X6S EX8000 is a high-end WiFi booster with speeds up to 3 Gbps.

With these ten tips, you should have no problem boosting your WiFi network without buying a new router. Make sure to have NetSpot at hand to check whether our tips helped each time you try one. We guarantee that by the time you get to the number ten, your WiFi will feel faster than ever before.
If you’re wondering how to improve WiFi signal strength, then we have good news for you: there are quite a few things that you can do to boost your WiFi without spending a single dollar. For example, you can use a WiFi signal analyzer to determine a more suitable place for your router, or you can switch to the 5 GHz band for an instant boost in performance, especially if you live in a densely populated urban area.
If you want to boost your WiFi without purchasing a new router, you can start by tweaking your settings. If you haven’t done so already, activate the 5 GHz band to benefit from its greater resistance to signal interference. You should also make sure that your router uses the least cluttered channel possible, especially when using only the 2.4 GHz band. Use a WiFi analyzer app to determine the best settings.
Yes, WiFi extenders really work, but their effectiveness greatly depends on their placement. A poorly placed WiFi extender won’t be able to perform nearly as well as a well-placed one, and it might even degrade the performance of your existing network by causing additional signal interference. That’s why it’s essential to play the deployment of any WiFi extender using a WiFi analyzer app like NetSpot.
The most expensive way how to boost your home WiFi is to buy a new router. Fortunately, there are many far less expensive ways that you should try first, including buying a stronger antenna for your existing router (if it has an external one), installing a WiFi repeater, or moving your router to a more suitable location.
You can instantly boost your WiFi signal for free by cutting all out WiFi leeches, which are basically unauthorized users of your internet connection. To do that, all you need to do is change your WiFi password and make sure that you’re using at least WPA2 protection (WPA3 is preferable, but not all WiFi routers support it yet).
Yes, WiFi boosters can greatly improve signal coverage by amplifying your existing WiFi signals and rebroadcasting them as a new network, which is why we recommend them to all WiFi users who want to know how to increase WiFi signal strength without buying a new router.
To give you a quick answer — that is how you get a great WiFi coverage.
Getting into some detail, not every spot will do for your WiFi router. A router won't do great near metal objects and the appliances that emit electromagnetic waves (the strongest ones are from electric stoves, microwave ovens, and dishwashers). Obstacles made from other materials than metal, can also affect the strength of WiFi signal. You also want to have your router installed on an elevated surface for a better signal broadcast.
Keeping your WiFi router up-to-date helps keep hacker attacks away. Malware developers keep coming up with new viruses that can steal bandwidth and spread themselves across the network to other devices. Getting new security firmware versions on your router consistently will keep your network secure.
WiFi repeaters, boosters and extenders help you get your WiFi signal to farther rooms and levels of your home or office space. Choose what will work best for you according to the size of your space, compatibility with your router and your budget. A good repeater or a booster can cost less than $100, and can be installed in several.
There are multiple wireless channels a WiFi router can broadcast on, however there are only a few non-overlapping available on 2.4 GHz band (3 to be precise). 5GHz frequency offers 24 non-overlapping channels. Usually when you get a router it broadcasts on default channel 1 or 6.
Because many owners leave their routers with the factory settings, those channels get overloaded. Find the least occupied channel in your area with the help of such software as NetSpot and switch your router to it.
