Thank you both, for your insight.

We've been testing for the past few weeks and I have to say that Meraki is "as 
advertised" in terms of their ease of configuration and deployment. We're going 
from n to ac, so I expect there to be fewer problems than a g to n migration.

Coverage gaps are a concern, but we should be able to more easily address those 
on a case-by-case basis due to the ease of meshing in areas that we previously 
couldn't run cable to.

Hi Rand,

Thanks for your comments to the wifi list about Meraki's lack of transparency.

We recently blindly updated the firmware before school started and appear to be 
paying a price. That price is at least two-fold, APs regularly stop accepting 
connections until rebooted (not cool) and reverting to previous firmware 
doesn't seem to be an option. Engineering is on the case, but tight-lipped.

We've also had a few MR16s start failing recently. I don't expect them to last 
forever but hope this is not a trend.


We switched to Meraki from an aged Cisco WLC/WCS system last January, and now 
have 110 MR16 APs. We are only about 1/8th your size in terms of student 
population, though our campus is fairly spread out, so I probably need about 
another 25 APs to cover most of it with reasonable density. I had four or five 
AP failures within the first couple months of deployment. Our symptoms were the 
AP would be completely non-responsive, with only the power LED glowing orange, 
no other lights or activity. After four of these failures, they started 
offering me MR34s as replacements, which was a pretty sweet deal. Then, after 
seven such failures, they released a firmware update in early June that seems 
to have stopped these particular failures for us - I've had one MR16 die since 
then, but it was just totally dead, no LEDs lit at all, so this is perhaps just 
a random failure, rather than the same pattern.

Still, they never really admitted that there was a firmware issue causing the 
failures. They just emailed me specifically to suggest that I installed the 
June update as soon as possible. The notes they sent about the changes are very 
vague:


  *   New VLAN debugging tools to help detect VLAN configuration problems
  *   Distributed layer 3 roaming (no concentrator appliance required)
  *   802.11k (radio resource management) and 802.11r (fast BSS transition) 
wireless protocols
  *   Hotspot 2.0/802.11u wireless protocols
  *   Enhanced stability and performance improvements
I guess the "enhanced stability" means that MR16s stopped bricking themselves. 
I asked specifically about this, and was told that the details of the update 
were "proprietary". Still, it seems to have done the trick.

Thus, I was surprised to read that the recent firmware updates were giving you 
problems, as I've not seen this, so far as I know. However, perhaps the issue 
is different versions of the MR16 hardware; if everyone else was seeing the 
nearly 10% firmware-caused lock-up rate that I saw our first six months of 
deployment, I hope I would have heard of it. Thus, I'm guessing most people 
didn't have the "orange power LED" failure; and similarly, perhaps your issue 
is only with your specific MR16 revision. (Not, of course, that the system 
gives us any info about different possible hardware revisions, so who really 
knows. Maybe all MR16s are identical, and it is just random, or based on some 
difference of deployment.)

Anyway, I'm wondering how you are tracking the problem. Do you just get user 
complaints when no one can connect, or is there some way to automatically 
monitor the dashboard, and reboot APs that have had zero clients for a long 
time?  (Is there a report that gives daily users per AP? I have not found 
anything better than checking the APs list several times a day, though it would 
be handy to see peak client counts and such.)  Is there any way to proactively 
reboot groups of APs early in the morning or something?

Thanks for any insights you can share.
