Currently, we have faced concern of MR18 indicates Ethernet 1 (100Mbits, Duplex). Could you please help to advise what would be issue of this status. It supposes to run and indicate as 1000Mbits instead of 100 Mbits.
I assume the AP is on port 1. That means the wires for pair 3 and 4 are not connected. I would replace the patch leads at both ends (hoping for the easy option), otherwise it is the actual cable running in the wall itself that has the fault.
