How to Monitor WiFi to Improve and Protect Your Wireless Network

The practice of WiFi monitoring has gained importance as more and more individuals and businesses implement wireless communication networks for their computers and mobile devices. A WiFi network offers enhanced convenience and flexibility that cannot be matched by a traditional wired network environment. These characteristics have led to the incredible growth in the adoption of wireless networks as the first choice for gaining connectivity in your home or office.

We are going to investigate some issues that WiFi networks introduce that affect the performance and security of your network communications. Then we will look at how WiFi monitoring can help alleviate or minimize those problems. We will also show you some WiFi monitoring software for your Mac that will help you maintain a secure network and improve its performance.

Potential Issues With WiFi Networks

WiFi networks pose some problems that are not present in a wired network. These issues can lead to degraded network performance as well as to an increased risk of unauthorized access or security breaches. We are not concerned with public WiFi in this discussion, and you should always exercise caution and employ a VPN when using a public WiFi connection.

Here are some of the performance issues that you may encounter with a home or office WiFi network.

  • Slow or no Internet access in some locations that should have connectivity. The location of your router may be the cause of this problem.
  • Slow performance throughout the network. This may be related to unauthorized users on your network. It can also be caused by overuse of WiFi channels leading to network bottlenecks.
  • The existence of intermittent connection failures.
  • Possible WiFi router crashes.

There are also security issues that accompany the use of a wireless network. Some of the most critical security concerns when using a WiFi network are:

  • Rogue access points — Unauthorized entry into your WiFi network can be accomplished by individuals located outside your building who are accessing your wireless signal through rogue access points.
  • Data Interception — Data transmitted wirelessly is more prone to being intercepted by unscrupulous entities than data traveling over a wired network. Unencrypted sensitive data can be compromised leading to financial or personal repercussions.
  • Hacker attacks — Hackers can go after your wireless network in a number of ways including man in the middle attacks, denial of service attacks, and endpoint attacks.

What is WiFi Monitoring?

WiFi monitoring is accomplished through the use of various software tools that can help address the problems that you may run into with your wireless network. Through the use of a WiFi monitor, you can improve the performance of your network so its users can enjoy a better network experience.

A WiFi monitor app can assist in properly locating your wireless router to cut down on slow performance and eliminate dead spots in your home or office. A wireless monitor can also be employed to enhance your network’s security by alerting you to the presence of intruders on your network. It can also be used to identify the location of possible rogue access points and help you tune the signal’s strength to keep it contained and less available to unauthorized users.

Who Should Be Concerned With WiFi Monitoring?

Anyone tasked with implementing or maintaining a wireless network needs to take the practice of monitoring their network seriously. This comprises a rather wide variety of individuals including:

  • Network administrators — Monitoring the network is one of the major responsibilities of corporate network administrators. They may use professional-grade hardware components or software tools to accomplish this goal.
  • Small business owners — In many cases, a small business owner who implements a WiFi network for their employees or customers will be responsible for maintaining the network. Monitoring tools are essential to ensuring that the network is safe and performing optimally.
  • Anyone with a home WiFi installation — Keeping the data that is resident on your home computers and devices warrants monitoring your WiFi to ensure that it is only being used by the members of the household. A WiFi monitor can be instrumental in helping you locate your router so everyone can connect from anywhere in the home.
