deco x60 random lan port downgrade speed
Hi my decos are having lan sport speeds downgraded randomly from 1000 Mbps to 100 Mbps, all my cables connected to them are cat6 certified and have checked them they don't have shorts or anything, for example I have an nvidia shield directly connected via cat 7a to the deco and randomly I will get 100 Mbps but when rebooting the deco the speed will again increase in the port to 1000 Mbps, also I have 2 laptops connected directly to 2 different decos via Cat 6e directly to the port and will again randomly go to 100 Mbps or sometimes they will not even get Lan signal, all my decos are in AP mode, I have checked all my cables for shorts and even replaced them with the same behavior.
Can anyone help?
Regards
