Meraki MX75 Disconnects

[cmi1984]

Currently I have a few MX75's at different clients experiencing an issue where all the ports, including internet ports, are experiencing an Ethernet carrier change causing disconnections to the internet and lan connections. Anyone else seeing this issue?

We don't have any MX75's, but we had a single MX65 that kept dropping our WAN connection on 10/29. We worked with the Carrier on rebooting the NID and it still persisted. We ended up swapping out the MX65 with another we had and it started working again. We are using Current version: MX 18.107.10 if that helps. We are going to RMA the bad MX65 that we replaced.

I have seen this on my home MX75, I haven't seen it in the MX19 firmware train that I have been running since it was released, I know it isn't marked as stable, but it definitely improved the situation for me so that it no longer happens...

I have the same issues and got a mx75 w/ same firmware replacement from meraki and went down after an hour.  I put back our spare mx68 and it's been up with no issues.  will a mx85 be a good replacement or keep the mx68?

I just started having this issue again.

I wonder if it relates to regular updates like IDP signatures?  It seems odd that we've all started having issues again.  I certainly havent done a firmware update...

I'm seeing the same issue with a brand new MX75. Unfortunately even the 19.1.6 firmware is showing the same issue. I am not sure if I got a lemon or the model is cursed.

@TrustPoint how much do you have plugged into in and how many clients are on the network?

[TrustPoint]

Maybe 75 total devices... about 40 users. It should be able to handle that without a problem. I'm using separate switches for the devices. The only thing plugged directly into the MX is WAN and a switch.

[cmi1984]

MX 19.1.5 no issues anywhere.  All of a sudden it just stopped.  I have a feeling they did something on their side.  As I didn't open tickets with every client but it stopped happening at all of them.

[TrustPoint]

Did you open a ticket with one of them? I just opened one... maybe they'll do their magic to me!

[cmi1984]

Yes but not with every client but they all got resolved.  They even RMA'd two of the devices I opened tickets on.  One I swapped the other I didn't.  Either way the issue was resolved on both and others who had the issue.

Hey i am also facing the below issues,

Currently I have a few MX75's at different clients experiencing an issue where all the ports, including internet ports going down, not able to get the local page by connecting the laptop and after the manual reboot , it is working fine then after some we are facing the same issues, i have raised an TAC , they have checked and raised an RMA for the devices and they are informing this the known behavior of MX75 device , i want to know, this is actual behavior MX75 devices and anyone faced the same issues?

We're experiencing the same issues with the MX75 for one of our clients.
A few months ago, we had seen the same issues at a different client. We had to RMA the device a few times before finally getting an MX75 that didn't have these issues. Firmware updates made no difference in our case.

For the problematic MX75 we're working with right now, the first replacement we received was even worse than the original. Lasting less than 24 hours before it went offline again. We're working with Meraki support on it, but I think we're going to avoid this model moving forward.

Hi cmi1984,

Please, check this Meraki Community posts here, and make sure to create a case with our Meraki Support Team so we can confirm which exact behavior you are experiencing.

• If possible, please make sure you have someone physically present with the impacted device and call into Support. There's a few physical observations and tests that need to be performed to ensure the issue being encountered is the one we are addressing with the interim firmware and not a different one. 
• The firmware mentioned is an interim patch. We have done extensive testing, but it is not marked as a stable or release candidate firmware. Make sure you accommodate enough time in a maintenance window to test your environment if we agree to proceed with the upgrade route. 

Please, keep working with our Support team to identify the best path forward based on your circumstances.
