@forte647 Too bad you got one of those ugly NICs running the r8169 driver. We have seen a lot of trouble with those lately. If I remember correctly this was an auto-negotiation issue most times. As George already said, can you try setting link speed to static GbE or 100M Fast Ethernet on your managed switch and try again? Please keep an eye on the link LEDs (switch and NIC) as well.
Are we allowed to use your picture in the wiki once we figure this issue out? As you are within a private IP range this shouldn’t be an issue privacy wise. Or we can mask the IP and MAC information if you don’t want to see those in the wiki.
