i just found one factor that seems to play a role in this but not exclusively.
i get better but still slow speeds when im not plugged into my docking station.
Im using a Kensington MD120U4 USB4 Mobile Dockingstation that gets power from a 100W USB PD Powersupply and all that is plugged into that dock is a Logitech Dongle.
While im plugged into this dock with the FW laptop the download speed is 0.5mbps.
when i unplug its ranging from 100 to 300mbps which is still very far from what the wifi should be capable of.
