    The connection is not working due to the incorrect speed.

Connect the same cable to a switch, and then the router to the same switch. Or execute the command:
ethtool -s wan speed 100 autoneg off duplex full
After that the connection is properly established with proper speed:
ethtool wan

Autonegotiation was working properly about a year and a half ago, so there was some changes made in the code that affected it. It also working with no issue with stock firmware.
