I've got Ubuntu server 19.04 on a repurposed 2011 Dell tower.
Back when it was windows, on ETH cabled lan i was at 1Gbp/S but on the Ubuntu now it won't recognize the hardware possibility.
Tried updating firmwares, messed with bios a bit too, the cable and router are both fully capable (modern equipment)
Doing sudo lshw -C network returns nothing.
Simply running sudo lshw returns the full spec list in which, under *-core we can see :
*-bridge description: Ethernet interface product: MCP61 Ethernet vendor: NVIDIA Corporation physical id: 7 bus info: pci@0000:00:07.0 logical name: enp0s7 version: a2 serial: xx:xx:xx:xx:xx:xx size: 100000000 capacity: 100000000 width: 32 bits clock: 66MHz capabilities: bridge pm msi ht bus_master cap_list ethernet physical mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=forcedeth driverversion=0.64 duplex=full ip=xxx.xxx.xx.xx latency=0 link=yes maxlatency=20 mingnt=1 multicast=yes port=MII speed=100Mbit/s
Running ifconfig :

And ethtool enp0s7
Settings for enp0s7: Supported ports: [ MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/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 Advertised pause frame use: No Advertised auto-negotiation: Yes Advertised FEC modes: Not reported Speed: 100Mb/s Duplex: Full Port: MII PHYAD: 1 Transceiver: internal Auto-negotiation: on Supports Wake-on: g Wake-on: g Link detected: yes
I know some of you might start with "There is no 1000baseT so not possible..." but i'm pretty positive the hardware IS gigabit compatible.
Thanks in advance :)
