Network gets restarted when using E1G42ET is Intel NIC

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.
