How to Fix MacBook Pro Keeps Disconnecting From WiFi


Why does my MacBook Pro keep disconnecting from WiFi?

The reason your MacBook Pro keeps disconnecting from WiFi is because it is running on an older version of macOS, there is possible interference in signals due to thick walls or metal objects or the router is far away.

 

Possible Causes

  • Malware
  • Interferences in signals
  • Software errors
  • Distance from the router

 

Malware

Any virus in the system can lead to big problems for your system. It is always preferred to ensure that you have an anti-virus app that regularly checks for any malware infection. Malware in the system also causes performance issues.

 

Older version of macOS

Apple regularly notifies its users about available updates. If you keep delaying them, there will come the point when the laptop’s efficiency starts going down. The first issue comes in the device’s lack of ability to turn itself on flawlessly. So, if your device keeps getting disconnected to WiFi, it may be a sign for getting the updates installed.

 

Interferences in signals

Thick walls and metal objects create disturbances and disallow your laptop to connect easily to WiFi. Ensure that there are no hindrances in the path of your router.

 

Distance from the router

If your laptop is too far away from the router – more than 150 feet – it may not get connected to WiFi. Ensure that you are near to your laptop to avoid such issues.

How do I stop my MacBook Pro from disconnecting from my WiFi?

To stop your MacBook Pro from disconnecting from WiFi, you should update its software, reset the SMC or PRAM, or check your router’s health.

 

If your router is overheating, it displays some performance issues.

 

To maintain your router’s good health:

  1. Don’t cover it up.
  2. Don’t put it in a place with no proper ventilation.
  3. Don’t place it near metal surfaces.
  4. Don’t put it next to a radiator.
  5. Don’t place it near a filing cabinet.

 

If the laptop finds it difficult to connect to the device, you should move it closer to the router. If it starts to work fine, it means that some interferences are disturbing your WiFi signal. Thick walls and metals within the router’s range cause your WiFi signals to drop.

 

A good way of dealing with this particular issue is to install a third-party app like NetSpot that can help you figure out which part of your house/workplace has strong signal strength.
