--- Comment #13 from AnAkkk anakin.cs@gmail.com --- It's weird, I got it to work fine on my Computer #1 with an Ethernet connection. I was using the nouveau driver, I usually use the nvidia proprietary one. I switch back to the proprietary, and the connection fails again.
Could this be related to the video driver somehow?
