How to Improve Wi-Fi Signal Strength?

Internet connectivity in today’s world has become as essential as showering and a weak Wi-Fi signal is definitely unacceptable. But this is something that most people who live in densely populated areas experience.

When the Wi-Fi signal strength in your home or office becomes weak, you start to experience wireless dead zones. Your browser is slow as hell and you may not be able to stream videos seamlessly.

If your wireless connection seems slow, you need to measure your Wi-Fi signal strength. This will tell you where dead zones are located in your home or office so you can make the necessary adjustments. NetSpot is the tool you need to measure Wi-Fi signal strength.

But before you start thinking about how NetSpot works and how it can help you with a weak wireless connection, what do you know about Wi-Fi signal strength?

What is Wi-Fi signal strength?

Today, Wi-Fi signal strength has become as essential as fresh air because all kinds of devices use it, including wearables, home appliances, and even security cameras. Without a strong wireless signal, wireless devices will not be able to reliably connect to the Internet to transmit data.

The strong Wi-Fi signal from the router allows these devices to function. You can even move from room to room while downloading videos from YouTube or social media platforms without losing your wireless connection. This implies that a strong Wi-Fi signal will greatly improve the user experience.

These are just some of the profound benefits of a strong wireless signal. Therefore, optimizing Wi-Fi signal strength is something you should strive to achieve with everything you have.

What affects wireless reception?

Several factors affect Wi-Fi, and due to its very unreliable nature, you need to know what can affect its performance. Here are some factors that affect wireless reception:


Wi-Fi signals can be partially or completely blocked by many objects or obstacles such as thick concrete walls, furniture, pipes, and even people.

The Wi-Fi signal blocker has a bad effect on the 5 GHz wireless network. This is because higher frequency wireless signals are more challenging to penetrate solid objects than lower frequency signals.

Physical distance

Wi-Fi routers do not have the same transmission power as cell towers for security and technical reasons. And many Wi-Fi routers can have trouble getting coverage even in a small apartment or isolated space despite a strong wireless signal.

This is why you need a Wi-Fi analyzer app like NetSpot to help you determine the coverage of your wireless router.

Router capacity

Not all wireless routers have the same capacity. Low-end routers that provide Wi-Fi access to the Internet are unreliable, especially if there are more than a dozen employees, fax machines, wireless security cameras, wireless printers, etc.

This means that a router’s capacity can significantly affect its ability to effectively transmit signals.


Did you know that Wi-Fi signals occupy the same radio frequency band of the electromagnetic spectrum of cell phones and actual radios, walkie-talkies, microwave ovens, baby monitors? If your router is near any of these points, they can interfere with your Wi-Fi signal.

Wi-Fi networks also suffer from mutual interference, a challenge that most people who live in apartment buildings or densely populated areas face from time to time.

How to measure Wi-Fi signal strength?

Before moving on to the next section, it’s important to know how to accurately measure Wi-Fi signal strength. Fret not: measuring wireless signals just got a whole lot easier these days, especially with a unique and innovative tool called NetSpot.

NetSpot is an easy-to-use product that comes with Wi-Fi analysis and survey application features that you can use to measure Wi-Fi signal strength. It’s compatible with macOS and Windows computers, and anyone can use it if you’re a little tech-savvy.

NetSpot supports all wireless networks broadcasting on the 2.4 GHz and 5 GHz frequency bands. While there are plenty of other Wi-Fi survey and analysis apps out there, NetSpot leads them all with its powerful features, ease of use, and affordable price tag.

NetSpot is currently the best native wireless site survey software for Windows and Mac. It provides at least 2 ways to analyze Wi-Fi:

  • Discover
  • Review

Discover mode instantly gets all the details about nearby wireless networks and displays Wi-Fi data as a separate interactive panel. The ‘Survey’ mode is designed to create an interactive heat map that shows very detailed information about each tested Wi-Fi network at each point on the map.

How to improve Wi-Fi signal strength?

The easiest or easiest way to dramatically improve your Wi-Fi signal is to buy a high-end wireless router. Most of these high-end routers come with multiple antennas as well as plenty of signal-boosting features. They help transmit strong Wi-Fi signals over long distances and even overcome thick obstacles.

But then, even the best and most expensive wireless routers available today have some limitations. And you may not be able to handle them.

However, using NetSpot’s Survey Mode, you can easily create a heat map of your Wi-Fi signal to see exactly where your wireless signal is weakest and strongest.

You can use this information to change the location or position of your wireless router so that it covers as much space — and evenly — as possible. You may need to place the router as far away from thick concrete walls, furniture, and other obstacles as possible. Placing it on a high shelf will be the best viewing position.

You might also consider switching to a pure wireless channel. To see which wireless channels are being used the most and which are the least used, use the NetSpot Wi-Fi Channel Analyzer. You need to find which wireless channels are duplicate and which are not.


Wireless routers can broadcast on multiple channels with only a few non-overlapping channels available on the 2.4 GHz band. The latter has only 3 channels, while the 5 GHz band comes with 24 non-overlapping channels. And since most Wi-Fi router owners leave their devices at factory or default settings, these channels become overwhelming. Use the NetSpot software to find the least busy channel in your area and then switch your router to it.
