the ANT27 is 12dB gain on the 5Gig which is just less than the 13dB on the antenna you have. You can select that one and safely be within FCC regs. You may disable the 2.4 radio since you won't have a 2.4 antenna.

you can use the AP to capture traffic on it's wired port to see if there are DHCP requests going out and responses to it's DHCP request. i tis under network wide /monitor / packet capture

for my $.02, there are settings to prevent devices from roaming as long as there is a tiny bit of signal. older cisco wireless phones for example can be set to a power saving mode that restricts it's radio from even looking at other APs to see if there is better signal until it nearly looses the one it has. Could be your scanners were designed that way to extend battery life.

When I configure APs, I make sure the switch port the AP is connected to is configured for access mode, on a VLAN that has DHCP, and has access to the internet. I usually use a vlan configured for user desktop PCs.

turning off meshing looks like a system wide option. if you only wanted the units to not mesh while working on them, you could change the RF channels to ones that are not in use by the local AP

At the risk of being too simplistic, can you mount it higher out of reach? If you mount in an enclosure, make sure it isn't metal. Any security cameras in the area?

I use this one on my MR74,84,86 APS. work great. don't get too warm. not too large https://meraki.cisco.com/product/security-cameras/security-cameras-accessories/security-cameras-accessories-power/802-3at-poe-injector/

Keep in mind, a Meraki AP that is a mesh repeater must be DHCP addressed

so depending on the bands your 5GHz is using it might be changing because of other non WiFi reasons like radar and such. what about trying to fix the speakers on 2.4 that doesn't have to change due to outside infuencers?

Are the laptops on the same AP and same SSID? I would expect that if they are, they will not talk to each other because I think the APs do not directly let devices see each other locally. if one laptop was on a different SSID, or if they were on different APs, they might work.

what is the environment you are in? office, manufacturing, home, near any industrial buildings? Your surroundings if they are other than an office building downtown may have an impact.

We have also used GRP and plastic boxes for indoor APs to be used outdoors and not seen any problems with signal strength. tested with the door open and closed without a difference in signal strength. if your curtain is large and heavy, there may be a metal mesh inside the layers for strength that you may have to consider. if it is there, depending on the mesh size, it may or may not have an effect. You know, just to muddy the waters

The DFS changes are only 5GHz, 2.4 shouldn't be affected. are you connected on 5 or 2.4 GHz?

when you look at the "Network Wide" then "clients" then click on the particular client and finally on event log, are you seeing disconnects and reconnects corresponding to the times of loss of connectivity to the device?

Thanks for the thoughts. looking like the industrial hubs behind the AP is the primary problem. at one of the locations, i can connect the power meters directly to the AP ethernet port and they work fine. When the meters are behind the switch, they lose connectivity. Part of the problem could be the meters don't initiate any communications. The metering "system" polls the meters.

I had a laptop on the L2 switch connect behind the repeater AP. i could get out fine with it. I didn't leave it there to try and reach back in to it from the rest of the network. I will give it a try. Thanks

I am using MR 86 APs as gateway and repeater. I have Allen-Bradley electric meters connected to the ethernet port of the repeater so we can remotely gather electrical usage in our factory. they have web servers built in. Sometimes they respond to pings fine. sometimes they don't. sometimes after a couple ping timeouts, they start responding fine. Usually they respond to HTTP requests even when they are slow to start responding to pings, and when the web session is running, pings are always fine. I have several of these GW/Repeater pairs in our plant. some seem to work fine. some seem intermittent. one doesn't let me ping across to the meters at all. I can see the IP addresses of the client devices in the list of clients. the repeater AP can ping the device(s) attached locally to it, but I can't ping it from the GW AP or anything else on the network. some repeaters have a small industrial switch with 2 or 3 electrical meters. I just upgraded the firmware to MR 27.5.1 last night and still see problems today. All the devices are on the same subnet with the APs in one site on the Meraki dashboard. wireless clients work fine from the repeater APs, although they are on a different SSID than the meters. I know this is a very specific problem, but any troubleshooting tips would be appreciated. It seems to stem from the network traffic being initiated form the network, and not from the devices on the wired port of the repeater AP

If you used a MR76 at the office with a 5G sector antenna pointing to each amenity block and the 2.4 radio disabled another 74 or 76 at the office with the 5G radio disabled and ANT20s on the 2.4 G antenna ports a MR74 with a 5G sector antenna at each amenity block pointing back to the office and 2 omni ANT20s on the 2 remaining antenna ports for client service. you could use the 5G for backhaul and 2.4 for client service

Furthering MerakiGeoff, you may need to add static routes to L3 switches on both sides of the wireless hop pointing to the opposite side

the antenna is a dual band, so each cable has a 2.4 and 5 Ghz antenna. the MR76 has both 2.4 and 5Ghz on each port, so every antenna port is exactly the same and you can connect the antenna cables wherever you want. you can connect a second antenna aimed exactly the same for MIMO service, or pointing a different direction for extended coverage width (sectors). the MR74 has separate antenna ports, 2 ports for 2.4 and 2 ports for 5Ghz. one could be used for vertical and the other port of the same frequency for horizontal polarization

In the first two locations, using ANT20 I would say you are wasting a good deal of your signal strength by letting half of it go outside your intended coverage area. if you move the MR74s diagonally inwards instead of leaving them on the edge of your coverage area, they will have a closer distance to the root AP, therefore better signal strength and possibly less interference from the vegetation because there will be less of it in the way. I am using MR74, 84, and 86 APs getting much further distances in clear space, and surprisingly good distance in my industrial setting with buildings and framing in the way.

are the band specific antenna ports on the 74 AP polarization specific? one port for horizontal and one port for vertical polarization per band?
