Today it happened after I resumed from standby (S3). My NIC is: 00:19.0 Ethernet controller: Intel Corporation 82579V Gigabit Network Connection (rev 05) If I search in google for "e1000e link up down" I see a LOT of users complaining. As far as I remember Alan Cox onde wrote this is a issue with "cheap chinese router" but I don't understand why there isn't a workaround for this annoying problem. Usually it establishes the link at 1000 Mbps and as long as I don't turn off the router, it negotiates the link speed correctly. Is there some workaround for this? If you need more information, just ask! Thanks.
