How can you troubleshoot network adapter driver issues on a Mac?

3 Reset PRAM/NVRAM

Parameter RAM (PRAM) or Non-Volatile RAM (NVRAM) stores certain system settings which can affect network configurations. Resetting them can resolve network adapter driver issues. To reset, shut down your Mac, then turn it on and immediately press and hold the Command (?), Option, P, and R keys. Release the keys after about 20 seconds. This process will reset the settings and may fix driver-related problems.

4 Diagnose in Safe Mode

Booting your Mac in Safe Mode can help diagnose issues with network adapter drivers. Safe Mode performs a check of your startup disk and loads only essential kernel extensions. To enter Safe Mode, restart your Mac and hold down the Shift key until you see the login screen. If your network functions correctly in Safe Mode, there might be a conflict with another software or service running on your regular startup.

5 Create New Network Location

Creating a new network location can sometimes resolve driver issues by resetting your network configuration to default settings. Open "System Preferences," go to "Network," and click on the "Location" dropdown menu. Choose "Edit Locations," then click the plus (+) button to add a new location. After creating it, click "Done" and select the new location from the dropdown menu to apply new network settings.

6 Reinstall Drivers

If all else fails, reinstalling the network adapter drivers may be necessary. To do this, you'll need to delete the existing network interfaces first. Go to "System Preferences," select "Network," and choose the interface you're having trouble with. Click the minus (-) button to remove it, then the plus (+) button to add it back. This action will force your Mac to reinstall the driver for that network interface.
