I recently ordered the UE300 V3 to be able to connect to Ethernet on my MacBook Air (Apple).
I saw there wasn't a download version for macOS Big Sur so I downloaded the Apple version MAC OS 10.9 to 10.15.
It has been working fine enough when it comes to downloading. The problem I'm having however is that I cannot seem to upload anything.
My downloading speed is very good, but I'm not able to email/upload files.
I've run a speed test and it says my downloading speed is at 163.5 Mbit/s but my upload speed appears to be non existent (NaN Mbit/s).
When I turn my WiFi back on my uploading speed is normal and allows me to email and upload files so my conclusion is that is has something to do with Ethernet connection of the device.
How can I fix this problem?
