Q: No gigabit ethernet connection anymore
Hello,
I have a Macbook Pro retina mid 2012 and I used to have always a Gigabit Ethernet connection, but since a couple of weeks I only get 100 mbit. After reading in the forums that the cables can cause this I tried with new Cat 6 cables, I tested already 10 different cables and I only get 100 mbit. I tried those same cables connection a different PC and I always got 1 gigabit with the other PC.
Since new cables didn't work, I bought a new Thunderbolt adapter and the result is still the same, I only get 100 mbit. Sometimes when I connect the Macbook to my home network I get 1 Gigabit right after starting the macbook. While having a 1 gigbit connection it disconnects and re-connects several times until it finally stays at 100 mbit.
Speed and duplex of the Broadcom NetExtreme Gigabit Ethernet card are set on auto negotation. Any suggestions?
