The POE injector is for testing purposes only, I don't have any in production whatsoever. Its not a cabling issue as a known good AP replacing the bad one on the same run will work. And the issue on the bad unit is replicated in a test environment. And now the final piece of proof: The Cisco Meraki POE+ injector test failed of course. As of this post, I just tested with a POE injector and the unit boots fine. There is NO network involved, just simple YES/NO boot and the POE+ fails. Hopefully a Meraki engineer will see this thread at some point. As long as they warranty them I don't care, but I now know I am not crazy. I appreciated everyone's input. I am marking this as solved.

I killed CDP on my test switch and no joy. Was a good try. There was a time I did disable CDP on my gear. I need to go back to doing that. As for going all same firmware, I am one man with a very large network (public school system) and as much as I would love to keep the world's most perfect network, to be blunt, it ain't gonna happen. (This is why i went Meraki on my WiFi...EASY.) I am in process of getting updated to 2920s for all of my older gear and once this is done, onto firmware via the IMC software. But you did make me remember....I have and just plugged up a Meraki POE+ power injector and alas no joy. There is definitely something wrong on the POE+ side on these trouble units. So this leads back to the switch side as again, no real consistency on model/firmware, other than a failure of maybe 2% of my overall inventory. Not bad, but i would prefer not to deal with the hassle. So the question is does the switch cause it or is it a failure on the AP? Hmmmm......

More information....as for my HP switches...I have a mix of mostly 5400ZL's (POE+ modules) and 2920's. I also have a few 2530's (poe+) and 2520's (poe). So its a mixed bag, and the software revisions are therefore mixed. The firmware on the MRs is 25.11 across the board and I have kept it current for the most part (although by looking its time to go to 25.12!). Here is the kicker though.....i can take a known good/new AP and plug it up to replace a 'bad' one and it works, thus pointing to to AP as the culprit. This scenario works in the field and back in my office. There are ZERO log entries for a 'bad' AP on a POE+ switch, but on a POE, it shows normal, i.e, power applied, etc. And of course, a good/new AP on a POE+ switch is normal as well. In the past, I have tweaked power settings on the POE+ switches all to no avail. I have even factory defaulted the AP with no luck.

I run HP/Aruba switches across my school system and have around 600+ MR42s and a handfull of MR52s. Early on and occasionally, I would have and AP go 'bad' in that it will not boot via POE and I bring back to my office and it would work when i used the switch in my office. Yet...the one I had put in its place in production was working which meant it couldn't be the drop/switch. (and external power supply always seemed to work). After this has happened a few times I realized something else was going on...then I stumbled upon the fact that my production switches are POE+ but the smaller switch in my office was only POE. Lucklily I have access to a known good POE+ drop on my wall which I also use for testing, and sure enough, these 'bad' APs work fine on POE but not POE+. I know i can RMA these, but collectively, I have dealt with 10 or so with this behavior and just find it odd. The switch software versions on my switches of course vary from model to model, but in most cases the software is relatively current. Just curious if anyone else has spotted this behavior.

No---just WPA2-Personal. I have, on another network, just turned on the 802.11r 'adaptive' option to see how that works out before rolling it out to my entire school system (we are using a template for 90% of our net).

Random disconnects from the known/assigned SSID. Typically, you can 'see' the same SSID via Windows (10) and reconnect, even though its set to do it automatically. Sometimes it may take a reboot. Windows event logs are showing a crash of the driver, which is what is leading me down the driver path....

Over the past school year, I have been getting reports of connectivy issues on a campus with all MR42 APs (current code) and more importantly a school full of (student) Dell Latitude 3150's using the Intel AC-7265 dual band wireless card. Current driver being applied for the card is 19.1.0.4. I have other, newer Dell models at other locations but with same AC-7265 card and NOT having issues. Very much thinking driver issues, but wanted to see if anyone else out there has had similar experience. In process of taking driver to V. 19.51.8.2 (most recent from Intel) to see if it helps.
