My LAN connection keeps cycling between "Enabled" and "Network Cable Unplugged". It cycles every 2-3 seconds

I do not know what is happening but my LAN connection keeps cycling between "Enabled" and "Network Cable Unplugged". It cycles every 2-3 seconds. (This is happening at work)
I have been experiencing this problem for a while but until now it has not been problematic as I have had wireless all the time to solve my problem.
Now, that I do not have wireless, this is dramatic as I cannot acces the network. This problem is however solved when I am connected to the network through a switch in a bigger office.
Does someone have an idea on how to solve this? I am running Windows 8.1.

Right on top of my head, ethernet plug not shoved in all the way and or dust bunny in ethernet jack and/or bend pins in ethernet jack.

uninstall network card in hardware manager and reboot computer to refresh the driver, other than check the cable/replace cable
