100 mb begrænsning

Hej Tipper, og velkommen.
Indtil der kommer en Mint-sagkyndig forbi, kan du se lidt på
https://linuxhint.com/check-link-speed-in-ubuntu/

Fortæl lidt mere om din hardware. Gammel maskine / kort?
Kør evt.

inxi -F
i en terminal, og vis os resultatet.

Hvis netværkskortet er gammelt kan det meget vel passe, at det ikke kan trække mere end 100MB/s. Det kan du ikke gøre noget ved softwaremæssigt. Men du kan købe ny hardware, maskine eller netkort.

Er den rigtige firmware installeret? Hvad viser

ls /lib/firmware/iwlwifi-7260*

Jeg har /lib/firmware/iwlwifi-7260-17.ucode
