Hi!

I have trouble getting 1000mbit out of my ethernet card.

I tried direct connection between two PCs with different cables, and no luck.

Today I tried connection to 1000mbit switch, and no luck, either. (Two cables, one was cat6, both short).

My computer sees 1000mbit being advertised by the other side, but does not advertise 1000mbit, "Link Speed was downgraded by SmartSpeed".

4.8.0-rc4+ kernel.

Does it work for other people? Card is:

Check your cables?

Of course if it isn't the cable, then it could even be a broken pin in the port. As far as I can tell, anything that causes one of the 3rd or 4th pairs of wires to not work will degrade to 100Mbit on just the first 2 pairs of wires and give that message. Some badly implemented switches can also cause it of course.

Ok, so it seems like broken pin in the port. I realized I had docking station available for the machine, and when connecting using that connector (not internal notebook one), I get gigabit speed.

Thanks and best regards,
Pavel
