Wondering if you ever solved this? I'm seeing Aeroscout tags not connecting to 3800s but fine on 3700s- nothing obvious in radio settings.

What is the ISP connection, and have you checked it for utilization? That part may be distinct from the phone problems. Is it only phones that have the Internet problem, by chance?

Hi Leo,
Nice to hear from you, brother. In this case, the primary image has updated and the AP is actually functional, serving clients and with long up times (see attached). It's just that the backup image will not update. You can try to force it in the GUI and it just comes back up with 3.0.51.0 after reboot every time.

Odd one here. Have 3702 APs that show exactly what you would expect for primary and backup images. In our case right now 8.2.141.0/8.2.121.0. Then we have a slew of them showing primary 8.2.141.0 and backup of 3.0.51.0. These WILL NOT take a new backup image.
Here's file system for both:

It may be obvious from lack of response, but I'm not seeing any way to. Is either in that mode or not, looking at PI here. It's a great idea though.

Agreeing with Philip,there is no granularity of license with the MR access points. For the MX, you choose between Enterprise and Advanced. Thankfully, the APs are brutally simple in this regard.

Leo- you have me curious. Here's the AP- no? https://www.manualslib.com/manual/378104/Cisco-Air-Ap1041n-A-K9.html I've never used it, but it sure reads as dual-band.

You can look in background tasks for polling and status intervals to manipulate, that's about your only places to adjust. I've found that PI can be buggy at times- you may want to make sure that all of the AP polling/status jobs are actually working and that none are "suspended". If they are, you may need a TAC case. If you have any other ping tools (SolarWinds, WhatsUp, etc) you might want to add the critical mesh nodes to that (I hate having to use two systems, but when you don't trust one you do what you have to do) just so you don't miss the important polling.

Ideally, they'd all be the same. But if you look at the specs on these, they are pretty close. I'm guessing you wouldn't have a problem at all.

Hi- when you changed the APs (I believe you are NOT using a controller- please verify) did you add the new ones as allowed devices in your RADIUS server, and verify that the RADIUS pre-share matches on both sides? And have you looked at what the RADIUS side logs might say? Could be helpful.

More of a concern are little, cheap power supplies. They can be horribly noisy in all frequencies and are easy to overlook. If your speakers required that sort of power supply and it seems like interference crops up, I'd look at the power supply before the speaker. A lot of devices are falsely blamed for interference when the cheapo "wall-wart" power supplies that they connect to are actually the guilty party.

Agreed with Sandeep on the drivers being looked at first, or if in OS X, checking for Apple updates. Rarely do you want to alter the entire WLAN environment for just a couple of problem clients, as - especially with WLC code, unfortunately- you may be trading one set of problems for another. You don't mention if you are running 1X, but if so the RADIUS logs may shed some light. If those logs show good auth but then you get the DHCP_REQD state, it really points back to the individual client.

FWIW, there are L-brackets to be had that let you mount the APs the "right" way on a wall, if you want to get the prescribed ceiling-style orientation. But I have hundreds of APs that went on walls out of necessity, and as long as you do everything else right there really is no concern. The antenna pattern won't be perfect, but WLAN is pretty forgiving.
