The network gets automatically restarted when we are using E1G42ET gigabit ET Network interface card, on Linux Microtik server OS. It reaches a speed of 108Mbps and restarts automatically after that. We need to reset the settings to get the network access again. I have checked the tested list of NIC cards from Intel site to check the compatibility of NIC card with the Server MotherBoard and workstation mother boards. Please suggest me a solution to this.
