So, whether your computer is refusing to join your home network or just not picking up any signals, keep reading for some helpful tips.

Why My Computer Won’t Connect to WiFi?

A computer won’t connect to WiFi if you’ve recently changed your router or upgraded your operating system. Other reasons include:

  • Wi-Fi is disabled
  • Wi-Fi card is malfunctioning
  • Issues with computer’s network
  • Outdated Wi-Fi adapter or driver
  • Password-protected Wi-Fi
  • Glitched router or access point
  • Too many connected devices
  • Issues around channel interference
  • You’re outside the range
  • The system is banned

– The Concerned WiFi Is Disabled

Have you checked whether or not the Wi-Fi network you’re trying to connect to is enabled? If not, you should do it right away because a disabled connection won’t be of any help.

It might sound a bit quirky, but in most cases, users have found that they have been trying for hours to connect their computers to a network that was disabled.

– The WiFi Card You’re Using Is Malfunctioning

If you’re sure that the WiFi is enabled and the drivers are up-to-date, the concern might lie elsewhere.

Yes, when you’re having trouble connecting to your home WiFi network or registering the IP address, it could be because your WiFi card is malfunctioning.

Usually, a WiFi card will have an indicator light that will tell you if it’s working properly. If the light is off or blinking, that’s a good sign that there’s a problem.

– Issues With Your Computer’s Network

Needless to say, your computer won’t connect to the internet at times due to internal shortcomings.

Yes, issues with your computer’s network utility can go beyond and prevent securing IP address connections to the nearest Wi-Fi router or access point.

Just like in smartphones, having a properly working network set up inside your computer is crucial.

In case you fail to sort one, facing the consequences is pretty much evident. When we talk about consequences, we mean failing to establish a connection.

– Outdated WiFi Adapter or Driver 

Have you checked in your WiFi adapter recently? No? That’s not a good idea.

It happens to the best of us. You’re working away on your computer, minding your own business, when you suddenly realize that your WiFi connection is acting up. After a bit of troubleshooting, you know that the problem lies with your WiFi adapter- it’s outdated!

A WiFi adapter is a device that connects your computer to a wireless internet network.

Most computers come with a built-in WiFi adapter, but if yours is outdated, you may need to purchase an updated version.

If you’re trying to connect to a Wi-Fi network and having trouble, one potential issue could be that your Wi-Fi driver is out of date or corrupt.

This can happen if you’ve recently updated your operating system, installed new antivirus software, or made other changes to your computer that might have affected the driver.

Outdated drivers are never welcoming, and the cases with WiFI connections are no different.

– Password Protected WiFi and You’re Using An Incorrect Key

Are you trying to connect to a wireless network that’s password protected? If that’s the case, make sure you’ve access to the password, or else forget about establishing a connection.

Password protected wifi and incorrect key xIf you try to connect to the Wi-Fi network, and it says “Password Incorrect,” you may continue entering the password again and again, but the warning you receive is the same – “Password Incorrect.” Check one more time to make sure you’re entering the correct password, and if you are, the question arises, “So why WiFi can’t connect to this network then”?

The most common and probable answer is that the owner has changed the old password and set a new one.

– The AUP Hasn’t Been Approved From Your End

Are you trying to connect to a new network? If so, you might approve the AUP. For those who don’t know, AUP makes you look at an acronym for Acceptable Use Policy.

It’s a set of rules that govern how people are allowed to use computer networks and other resources.

The goal of an AUP is to ensure that everyone has fair access to resources and that vital systems are not disrupted by individuals acting maliciously or unethically.

While the specific rules of an AUP will vary from one organization to another, common prohibitions include unauthorized access, vandalism, spamming, and copyright infringement.

– Glitched Router Or Access Point

A router is a device that offers a wireless connection or simply connects two or more networks, such as the Internet and a home network.

An access point is a device that connects devices to a wired network, such as a router. But what if you’ve got a faulty one?

Glitches can occur in routers and internet access points, which can result in lost or intermittent connectivity issues.

Several possible causes of this problem include loose cables, incorrect settings, or outdated firmware.

In most cases, the problem can be fixed by power-cycling the device or simply resetting the settings. However, if the problem persists, replacing the router or access point may be necessary.

– Too Many Devices Are Already In Lieu

Although most routers are designed to accommodate many devices, there can be limits on the number of Wi-Fi connections that can be made to a single network.

This is often due to the router’s hardware or firmware, and it can result in poor performance for all devices connected to the network.

Whatever the case, the important thing to note is that if you’re trying to connect to a network that has already reached its saturation, the end result will eventually be a failed attempt.

– Issues Around Channel Interference

WiFi channel interference can be a major issue, especially in densely populated areas.

Interference occurs when two or more devices try to use the same channel at the same time, leading to slower speeds and connection problems.

If you’ve ever tried to use WiFi in a crowded place, you know that the experience can be frustrating.

Slower speeds and dropped connections are often the results of interference from other wireless devices. In worst cases, you might even fail to build a connection.

– You’re Outside the Range

It’s hard to imagine life without WiFi these days. We use it to stay connected with our friends and family, to work from home, and to stream our favorite shows.

But have you ever wondered just how far your WiFi signal could reach?

The answer depends on a few factors, including the type of router you’re using and the construction of your home.

In general, however, most WiFi signals can reach between 150 and 300 feet under ideal conditions. However, obstacles like walls and furniture can drastically reduce the range of your signal.

Well, the calculation is simple. If your device is out of capable reach, attempting to connect won’t bear any fruitful result.

– Your System Is Banned

Although very rarely, a crucial thing to keep in mind. There are instances when suspicious activities have led to a permanent ban.

Irrespective of your concerning network, the corresponding card comes with a unique identifier. The same is often known as a Media Access Control address.

When and if an organization ends up detecting suspicious activity, the administrators can even ban the address.
