Getting the Belkin USB-c Gigabit Ethernet Adapter to work on macOS Catalina
For those of you who were as frustrated as I was these last couple of weeks since upgrading to macOS Catalina and realized that your Belkin USB-C Gigabit Ethernet Adapter was only providing a maximum of 100Mbps throughput, read on for a solution.
- Plug in the adapter and make sure it's connected to your network via an Ethernet cable
- Open System Preferences
- Click on the Network icon to open network settings
- Select the Belkin adapter from the listed services in the left panel
- Click the Advanced button to open advanced settings for this adapter
- Click on the Hardware tab
- Select Manually from the Configure menu
- Select autoselect from the Speed menu
- Click the OK button
- Click the Apply button
That's it. You should now experience full duplex gigabit Ethernet speeds (I checked using a popular speed testing sight). I have 400 Mps service and got exactly that using just the Ethernet adapter (turn off Wifi to test)
