KN-3811 USB Speed over Wi-Fi

[KYTECHNGAMING]

Hello, 
Seagate disk is inserted into the KN-3811 usb port. 
No matter what I do, both wired and wireless copying speeds do not exceed 40mb/s. It's like it's communicating as USB2.0. 
I tried many things such as Wi-Fi settings, disk formats, different USB cables, but there is no change.

Could it be a driver problem? Where might the problem be?

Self-test is hidden in the next message.
