This is an older laptop (thinkpad t420) so I thought it might be a dead or dyong ethernet port/controller. ...nope. i got gigE connection just fine when I booted into windows 10.
This used to work. The drivers in linux have degraded horribly since I bought this machine. Even my wifi is crippled to slow speeds (2mbps) now. I dont want to get rid of this computer because it works fine for everything else (win10 works fine) but what in the world happened to the driver support in linux?
Was trying to copy a couple gigs of files off my laptop yesterday and decided to plug into ethernet to make it go faster.
The ethernet took 5 mins to establish link.... at 10mbps.
"Bad cable?" so I tried a different cable (known working gigabit). Same shit. After turning off autonegotiation the link failed to work at all and even manually trying to raise the connection with ifup was failing.
I ended up having to reboot my laptop because the network stack got so messed up.
