Lol - the reason was in a power saving mode. Setting it to high performance did the trick.

Thanks everyone. I also think its a hardware issue, as a USB stick works well.чт, 29 окт. 2015 г. в 13:38, Tim <ignored_mailbox@xxxxxxxxxxxx>:Allegedly, on or about 26 October 2015, Kseniya Blashchuk sent:

I would strongly suspect the network card is broken. Flapping is a
common effect seen in busted network cards. I've even heard it said
that it's a deliberately designed failure indicator.
They do get busted easily enough, especially if you connect equipment
between different rooms, or buildings. There can be quite a voltage
difference between the mains wiring, many cards don't have adequate
galvanic isolation, or none at all. And long wiring can pick up EMI
from lightning storms.
