Compilation of Fixing WiFi Errors on Mac (Part 1)
Below, Mytour will introduce and guide you through some methods to fix WiFi connection issues on Mac:
Method 1: Check Apple Software
After upgrading to the latest macOS versions, some users have reported Mac encountering difficulty in connecting to WiFi networks.
Apple also releases bug fixes and advises users to update to the latest macOS version as soon as possible. For MacBook Air users relying solely on WiFi connection, they can share the connection from mobile devices to update to the new version and fix the issue.
Furthermore, if using beta versions of macOS, since these are not the final stable versions, encountering errors, including WiFi connection issues, is inevitable.
Method 2: Troubleshooting Wifi Connection Suggestions on macOS
When your Mac attempts to connect to any Wifi network, macOS will diagnose any issues. If it detects any problem, beside the Wifi icon at the bottom right corner of the system tray, it will display alternative Wifi connection suggestions. Click on it to choose a different connection.
Method 3: Contacting Internet Service Provider
If the root cause of the issue lies with your Internet Service Provider, there's nothing else you can do but to reach out to them for assistance.
Alternatively, another possible cause could be faulty cables or the impact of external weather conditions affecting network connection speed. In this case, you can still reach out to the provider for assistance.
To check if there are any issues with the network connection to the website you're accessing, you can run a Ping test.
Method 4: Rebooting the Router
If you've tried the above methods to no avail, try rebooting the router to fix Wifi issues on Mac and check if the problem persists. To reboot the router, first turn off the power, then unplug all power cables, plug them back in, and turn the device back on.
Method 5: Restarting Your Mac
Similar to rebooting the router, try restarting your Mac and see if the Wifi issue persists. If after restarting your Mac, the Wifi issue persists, try turning off Wifi and wait for a few seconds, then reconnect to force Mac to scan for available network connections.
To turn Wifi on or off, click on the Wifi icon in the menu at the top right corner of your Mac, then select Turn Wi-Fi Off.

Next, try reconnecting to the Wifi network you just forgot, enter the Wifi password, and check if this method of fixing wifi issues on Mac has resolved the problem.
Method 8: Check if the Router is Overheating
If you have tried a series of solutions and the Wifi issue persists, try checking if your router is overheating. Internet or Wifi connections are often interrupted if the router is too hot. Try moving and placing the router in a well-ventilated position, easy for heat dissipation and ventilation.
Method 9: Check Router Placement
Try relocating and placing the router in a different position. Note that the router should not be placed on or near metal surfaces, as this can hinder heat dissipation. If the router gets too hot, it can cause network connection errors, interruptions.
Also, try placing the Mac near the router to see if the connection signal improves. If the connection signal improves, there's likely some device causing interference, leading to Mac's inability to connect to Wifi.
Method 10: Investigate if there's anything obstructing the connection signal
There are various factors, devices affecting the Wifi network signal strength, which could be walls, or metal objects, ... .
To pinpoint the culprit affecting the connection signal, you can seek help from the NetSpot app (priced around £7.99) to create a Wifi signal map indoors. Move your Mac around to find ideal router placement spots for stronger Wifi connection signals.
If you identify the culprit causing weak Wifi signals, Mytour recommends using a Wifi extender to transmit a better network signal.
During the Wifi extender setup process, ensure you have changed the SSID (Wifi name) and password of the new device to match the name and password of the current router or modem. This way, Mac can choose any device that provides a better network connection without needing to switch or enter a new password.
Lastly, another possible cause could be other electrical and electronic devices, such as fans, microwaves, mobile phones. Wifi connection may slow down if you connect multiple devices simultaneously to the same network, or it could be due to microwave interference. Try placing the router away from these devices.
