As an alternative to looking in the sysfs (/sys/class/net) as I suggested, you can also install the "ethtool" package and run it with the interface name. E.g.:
$ ethtool eth0 Settings for eth0: 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: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Advertised FEC modes: Not reported Speed: 1000Mb/s Duplex: Full Port: Twisted Pair PHYAD: 1 Transceiver: internal Auto-negotiation: on MDI-X: off (auto) Cannot get wake-on-lan settings: Operation not permitted Current message level: 0x00000007 (7) drv probe link Link detected: yes On Tue, Apr 27, 2021 at 10:35 PM Russell Senior <russ...@personaltelco.net> wrote: > > Again, my theory (which is consistent with everything you have > reported) is that your ethernet connection is training at 100Mbps > instead of gigabit.
