Rolling back to MR 30.6 did not help.  Talked to Support and will be downgrading same two WLAN networks to version MR 29.7.1 ... View more

We have MR46s, MR53s, MR56s, MR74s, MR76s, and MR86s, with a huge majority of them being MR56s.  Almost all of the APs showing degraded Ethernet are the MR56s.   Just talked to Meraki Support.  I have two WLAN networks scheduled to be downgraded to version MR 30.6 tonight per Dev Team's and Support's recommendation.  We'll see if this helps. ...

  I noticed version MR 31.1.6 was available as a Release Candidate.  I upgraded a few wireless access points to version MR 31.1.6 and it made things worse.  The Meraki access points would not pick up a DHCP address and could not go into Gateway Mode.    I had to revert back to MR 31.1.5.1 and the Meraki access points were able to pick up DHCP addresses again, going into Gateway Mode normally.   Ethernet is still degraded.  Meraki Support has acknowledged the bug and escalated to their Dev team.  In the meantime, Support is saying to go back to version MR 30.6   Will try that soon. ...

Hi there - There is definitely something wrong with MR 31.1.5.1   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. ...

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. ...

I have to agree with your assessment.  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. ...
