what do you actually want to achieve by turning it on? i feel like this is an x-y problem

[simple sierra]

I have a problem with my internet connection in Arch Linux. It is, but it is low. And in one guide one man recomend activate auto-negotiation to solve my problem

have you done a speed test in arch vs windows to test?

[simple sierra]

Yes and no

I have done a speed test in arch vs my phone

[rough folio]

it could be a problem with your wifi card itself actually

[simple sierra]

But my PC connected with ethernet

[rough folio]

then maybe something to do with the network manager?

[simple sierra]

Measured the network settings in the system settings, entered this command from the terminal:

Internet speed 10 times slower than expected

[rough folio]

well that seems to be the command that would turn it on

did it help?
