AP (MR18) show up 100 Mbits Full Duplex

[Phearin_Seng]

Dear All,

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. 

Really appreciated for any comments. 

Thanks,

Phearin

The port has auto negotiated down to 100mbps.

This is typically a cable issue - bends/breaks in the cable causing 1 or more pairs to be broken, too long cable run etc.

If it is plugged into a Meraki switch you can use the cable test tool.

@PhilipDAth thank you for information. I did cable test. We discovered that the 100 Mbits status as below.

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.
