Problems with wifi connections in your laptop can surely cause a headache. But if you can identify your problem it doesn’t take much to solve it. You can solve the problem regarding your wifi connection sitting in your home, without costing you a single penny for service charges.

So let me help you by listing some common issues regarding the wifi connection in your laptop and how you can fix it for both Windows 10 and Mac.

Why Does My Laptop Keep Disconnecting From The Wifi? (Windows 10)

Wifi can get disconnected for a whole lot of reasons. The most common reason your wifi can get disconnected is having a poor connection.

If the router you are using or the internet providers are having an issue with their connection, the laptop would likely get disconnected from the wifi. Sometimes the inbuilt wifi adapter inside the laptop can also be faulty making it disconnect from the wifi.

Another reason can be the usage of outdated drivers or a faulty update.

Wifi can also get disconnected because of the power management setting. Laptops tend to save battery power and turns off the wifi automatically. Also, in the power saving mode, wireless adapters settings sometimes provide less power.

Because of this, a slight fluctuation in connection can cause the wifi connection to get disconnected. Sometimes the problem can be due to the TCP/IP configurations.

Wifi can also keep disconnecting if there is an issue with the DNS server. The connection faces problems because of heavy traffic if you live in an apartment with many routers and your channel can’t provide the internet.

Wifi also can get disconnected when you are in a public network rather than a private network. It is really hard to figure out the exact problem that is causing your laptop to lose connection frequently most of the time.

Now that we have discussed wifi disconnection on Windows, it’s time to talk about wifi disconnection on Macs.

Why Does My Laptop Keep Disconnecting From The Wifi? (Mac)

There could be quite a few reasons your Mac computer may cannot connect the internet via wifi. These options can range from the service provider’s network being taken down to hardware/software issues within your Mac.

Let us explore some of the possible reasons that could cause this phenomenon:

Service Provider’s Internet Being Down

The Internet Service Provider (ISP) is the company that provides internet services to all the houses in a particular area or neighborhood. They are in control of what internet speed we receive and how strong our network is.

They can also manage how many people are connected to a particular network at a particular time.

Since your service provider provides your internet, any problem in their network will directly lead to a problem in your network. If their network of services fails, it will not only affect your internet but also cause everyone else’s wifi to act up in your area.

So if there is a common disconnection problem within your neighborhood, it is probably because there is something wrong with your network service provider.

There are several kinds of issues that may cause your internet service provider to fail. The problem could be technical, hardware-based, or even financial. If most people fail to pay their bills, it could cause poor services from the internet provider.

There could be natural or man-made damage to the network infrastructure such as poles breaking down due to a heavy storm or cables getting damaged because of construction work. These could all result in wifi getting disconnected on your mac.

Hardware Issues On Your Mac

Sometimes hardware problems may cause disconnection of the internet on your Mac computers. These can range from severe issues such as a busted modem within your computer to merely dust seeping inside your Mac.

Dust can cause a lot of problems so it is very important to keep your mac clean if you want to avoid such trivial issues. Fine dust particles may get trapped between connection points and it may cause those connection points not working. Therefore you must always keep your computers clean.

Again, other hardware-based issues are beyond our capabilities such as a broken modem or wireless drivers on your computer. Unless you know what you are doing, it is best to leave these kinds of repairs to the professionals.

Because if you try to tinker with your computer yourself, it may cause a breach of your warranty.

Although it is rare for a hardware problem to cause your wifi getting disconnected, it could sure be the problem. If your wifi works on other devices but not on your MAC computer and if your computer allows for cable internet to work but doesn’t cooperate with wifi, then it could be because of a hardware issue on your computer.

Software Issues On Mac

Another group of reasons that may cause wifi getting disconnected automatically is software-related issues. While macOS is one of the best-operating systems for computers, it is not completely free from bugs and glitches.

Wifi can, a lot of times, get disconnected automatically if there is a stronger network that you have previously connected to nearby. There can also sometimes be glitches that don’t let your computer connect to your wifi network.

Again, if your wifi network is weak then it might also prevent your computer from connecting to it.

If you or any of your family members change the password of your wifi network then it will also result in your computer getting automatically disconnected from the internet.

This only happens so that the privacy of your home wifi might be preserved. You can reconnect to the network by entering the new password and if there are no major issues, your computer should connect just fine.

There Is A Problem With Your Router

The router is a key element in connecting to wifi. It is this device that converts your cable into wireless wifi signals. If this device is not working accurately then it may result in an unreliable connection.

If connecting to the internet through an ethernet port works but your laptop cannot keep a stable connection with your wifi router, then there could be a problem with your router. Routers are prone to overheating, hanging under too much pressure, and even dust allocation at times.

You should also check the wall adapter and the wall socket that your router connects to. Again, you should make sure that the cable that connects your router to the internet is not damaged.

A damaged cable will also result in a poor internet connection. This poor connection might result in your wifi getting disconnected automatically at times.

How To Fix Laptop Disconnecting From Wifi? (Mac)

Here are some steps you may take to tackle this situation on your Mac computers:

Check For Software Updates

Apple computers have a history of wifi-related problems that are caused because of software issues. However, they are always quick to patch up any major wifi-related issues on their computer with a software update. Check if you received any such updates and if you do, download it and update your computer. It should fix the problem. And if you somehow cannot connect to wifi, consider cable internet or use the data on your phone.

Consider Apple’s Wifi Recommendations

Your apple computer automatically scans your network for issues when you connect to your wifi. If there are any major problems with your internet, macOS will automatically identify and flag them. Then they will recommend a few solutions for your problem. Do consider them.

Restart Your Router

Sometimes a simple solution is all you need for your wifi-related problems. Wifi routers can get unresponsive and lose the connection sometimes. To restart your wifi, turn off its power source and wait for about 30 seconds before turning it back on. This should fix any trivial issues you may have.

Check-in With Your Broadband Provider

Sometimes the problems may arise on your provider’s end. There is not much you can do during a situation such as this. Wait until your broadband provider fixes the issues. This can be very frustrating and potentially disastrous depending on your needs.

Consider using mobile data until your provider ultimately gets around to fixing the issue. Make sure to file a complaint and consider switching to a different service provider if these problems occur regularly.

Apple Diagnostics

You may choose to run apple diagnostics in order if you still cannot identify the root of your problems. Here is how to do it:

  1. Disconnect all external devices.
  2. Restart your Mac while holding on to ‘D’ on your keyboard.
  3. Choose your preferred language and wait until the diagnosis is finished.
  4. If a problem is identified, Apple will suggest recommendations.

Restart Your Device

There could be a temporary bug with your computer. Turning it off and turning it back on is a surprisingly simple but effective solution for a lot of your problems. Although it is unlikely to fix your problem, it doesn’t hurt to try it for once.

Use Apple’s Wireless Diagnostic Test

The Mac operating system offers a built-in wireless network that allows you to scan for and detect any network-related issues you may have. Here is how you turn on the diagnostic tools:

  1. Either search ‘Wireless diagnostics’ on spotlight or hold Option/Alt and press the icon indicating wifi. Then open the diagnostic tool.
  2. Click on Window>Performance from the menu and click on continue to run a report.

This will generate the transmission rate, signal quality, and signal and noise levels of your network. If you can decipher it, then it should help you diagnose the problems that are occurring with your network.

Forget Network

Try clicking on forget network and then connect back to your wifi by entering your password. Sometimes glitches may cause connection problems and resetting your wifi and reconnecting to the network might be just what you need to fix the issue.

Consider The Location Of Your Router

The location of your router can play a major role in the connectivity of your router. If the router is too far away, then it may cause connection problems. Again, if there are obstacles that block the network, such as a large metal object then it might cause connection problems for you as well.


Whether you choose Windows or Mac ultimately depends on your taste. However, both operating systems have their share of problems with connectivity. While MacOs is more user-friendly, Apple computers could be more expensive to fix.

Therefore I hope this article will help you achieve a better understanding of the issues that may cause your wifi to lose connection and better prepare you to identify and potentially fix them.
