Method 5: Try to Use USB 2.0 Port Instead of USB 3.0 Port

Due to frequency interference, the working frequency of USB3.0 and the WiFi frequency of Mac may interfere with each other, causing the Mac to fail to connect to WiFi. If you need to use the USB interface, please try to buy a USB 2.0 Hub to avoid interference problems.
