RM500U Low speeds on 5G

Ok. But if I test on my Phone, I get similar readings. I mean the provider itself is supporting speeds in max peaks of 300+ Mbps.

I am not sure if we can do anything here?

OK. If the provider just can provide the 300+ Mbps, It is not a problem now.
I just guess that the USB speed、CPU Performance might also affect the speedtest.
On Windows, the speed performance should be much more better.
