Yesterday i made a sudo apt update and reboot. Later i realized my speed was kind of slow so i checked in Network Interfaces Gui setting was at:
- allow auto-negotiate: unchecked
- speed: 100 Mbits/s
- duplex: half
Then decided to check the firts option and wired connection began to connected/disconnected back and forth.
Tried setting it to manual with no results. This is the output of ethtool:
Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supported pause frame use: No Supports auto-negotiation: Yes Supported FEC modes: Not reported Advertised link modes: Not reported Advertised pause frame use: No Advertised auto-negotiation: No Advertised FEC modes: Not reported Speed: 100Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: off MDI-X: on (auto) Cannot get wake-on-lan settings: Operation not permitted Current message level: 0x00000007 (7) drv probe link Link detected: yes
I tried with another laptop and speed works at 1000 Mbps so why mine doesn’t since it was ok.
