Check the cable...could be that the cable has been to much bend

cable is okay, and issue cannot be multiple access point at a time.

What APs are you using ?

What firmware ?

What switch ?

Hi @Indian1,

Root Cause Analysis was recently introduced for the Ethernet uplink speed degraded alert. If you click on the link in the alert, you will see alert details, as well as the suggested actions that may help to resolve this issue. I would start with these actions first.

Additionally, see details about this alert and suggested steps in this KB.

I also have several Meraki MR56s have their Ethernet speeds degraded.  Here is my feedback on another posting:

We were running on version MR 29.XX and everything was fine.  The Meraki APs all negotiated to either 1000 or 5000 Gbps depending on the Catalyst switch model.  We held off upgrading to version MR 30.XXX because of 802.1x problems that Meraki Support confirmed.  We upgraded straight to latest version MR 31.1.5.1 last month.  Everything was running fine up until this past week.  We then had multiple MR56s drop their Ethernet links to 100 Mbps with Degraded Status.  Looking at the forums, we have power-cycled the switchports and also power-cycled the Catalyst switches.  We have even shut down the APs for half-hour as suggested and powered them back up.   50% of the time, the APs would come back to 1000 or 5000.  The rest of the APs stayed with 100 Degraded.  We checked the cabling and there are not errors.  Something from the latest firmware is definitely causing all these Ethernet speeds to be degraded.
