Langsames Ethernet auf Surface Book 2, 15"

Ich habe diese Frage auch schon auf dem US Forum gestellt. Vielleicht ein User in Europa ähnliches erlebt und weiss einen Ausweg (ich bin in der Schweiz):

"I have a 500/50 Mbit connection. Connection Speed on the Network has been verified. When connecting my SB-2 15" (1809, all updates, Surface Diagnostic tool run - no problems) by Ethernet, I consistently get speeds between 83 and 97 Mbps, very rarely up to a peak of 100 Mbps.

The Surface Ethernet Adapter is set to 1 Gbps in all cases (from the default 100 Mbps)

The ethernet connection has been established in four different ways, always showing the same speeds:

- Surface Dock ethernet connector

- MS GB Ethernet connector to USB-C port on SB2

- MS GB Ethernet connector to USB 3 ports on SB2 (both)

- Third party GB Ethernet connector to USB 3 ports (both)

On the side, when using WLAN on a Netgear ORBI Mesh Router and either the built in Marvell WLAN card or a USB Wlan Dongle (Netgear Nighthawk A-7000), I get identical speeds. This holds when the the dongle is connected to the SB-2 's USB Ports (incl. USB-C) as well as the Surface Dock.

These facts lead me as well as the provider technician to the conclusion, that my SB-2's USB ports (including Surface Dock/Connector) cannot handle more than 100 Mbps.

Has anybody on this Forum ever reached significantly faster ethernet speeds (200-400 Mbps or more) on an SB2 15"?

Would such a person be so kind as to tell me how and with which provider and where? (I am in Switzerland)."

Ich würde mich sehr über einen Erfahrungsaustausch freuen!
