    But have you raised it that you have now had multiple failures? IMHO I would be looking at something which is exactly the same between all the failures - which points towards POE injectors. But it could just be a freak failure of devices.

    I did mention we didn't use Meraki POEs but they didn't seem interested

    at the end of the day anything that provides POE should be fine - It was just more wondering if it was something else rather than the AP's themselves causing an issue (maybe overloading/surge etc)

    It could just well be that you have been unluck.

    I think when I get chance I will start changing them for original Meraki items, if these are supplying overvoltage over a long period they might causing damage. I think a suck it and see approach for now. Thanks for the advice though.

    Bit of a late response but we had our entire wireless network* replaced with Meraki MR16 and MR24s back in February (connected to Cisco Catalyst 2960S PoE switches) - we had so many APs fail that Meraki ended up upgrading all the APs to MR18/MR26 units at no cost. It seems they have had issues with bad batches of the MR16s.

    *The old system was Cisco 1131 APs on Cisco 4404 WLAN controllers with ACS and WCS in the backend

    We also installed a batch of MR16s over the past 12 months and had about a 10% failure rate. Got the same response as OP - Meraki just RMA'd them and couldn't give an explanation. Response from our Meraki account manager was pretty good, and the return time wasn't bad. We're just about to buy a batch of the MR16 replacements.

    we bought various AP's MR26 and MR34, all are failing with high latency. Even if they are only connected with 2 or 3 users. We tried everything, our case is now over 4 months old and it is still not fixed. Did the RMA resolved the issue? Does anybody have any idea what's going on?

    Does the AP itself have high latency if you run a ping from it? That sounds like it could be a network issue rather than the AP's but without knowing more its hard to tell.

    Do you have legacy mode enabled.

    We're a BSF Managed Service school so our ICT infrastructure is managed by a third party (but not for much longer \o/) who are very secretive and keep us at arms length for most trouble shooting however we're still having problems with our new Meraki APs.

    The issues are under investigation by Meraki, the installer (Logicalis) and our managed service provider (Lend Lease ICT) and have also been going on for a number of months. We mostly have issues with OS:X 10.8.* MacBook clients roaming between APs - we've been suffering from very high latency, random disconnects, connection but no internet pass through and other general network instability; restarting the affected AP cures the issue in most circumstances but after 5-10 minutes it also often resolves itself (not great at the start of a lesson for teachers). This can happen even with only one client attached and tends to be more common in areas where there are external wireless inteference sources (nearby houses domestic wifi routers, etc.) which makes me think it's likely a problem with either channel assignment or band steering as N clients seem more heavily affected, unfortunately without access to the dashboard (thanks to the managed service) I can't see how any of it has been setup or view any of the logs

    This might help with troubleshooting for some of you - https://meraki.cisco.com/blog/2011/0...fi-deployment/

    Hope this helps some of you and please update the thread if you get anymore information from Meraki as it looks like there's a few of us suffering issues.

    As someone who is considering Meraki for our new wireless install has anyone with an MR18 had one fail? I've got one of the free ones from the webinar (MR18) and its been fine.
