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.
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?
