Dear Community!
I have wired my home and in some rooms the link is only 100Mbps full-duplex instead 1Gbps full-duplex.
On the both end of the link, there are Mikrotik devices (and confirmed that both can do 1Gbps speed).
One side: RB4011 Other side: hexS FTP Cat6 cable used in wall.
In other rooms where different type of (brand) FTP cable is used, the link normally works with 1Gbps so I assume that there is no problem with how I wired the cable into the wall plug and patch panel.
Auto-negotiation is used on these ports and 1Gbps is set, but when the link establishes, in Status only shows 10/100 speed for 'Advertising'.
Fixed speed with 1Gbps speed, the link can't estabilish (nothing can be seen).
I have tried this cable outside the wall (though it is much shorter) with a different socket (not that in-wall socket I have everywhere), that one worked perfectly with 1Gbps speed.
What can be the problem in this case? Can anyone help with further investigating this?
Thanks!
