Hello everyone.
I have set up three access points 2x AIR-AP3802I-B-K9 and AIR-CAP3702I-A-K9 running 8.10.180.5 with one 3802i acting as ME controller + ap, while others are lightweight members. They're also members of the same AP group with single SSID.
Both 3802i APs are working as expected, when I roam from one's location to another, my Samsung android phone reconnects automatically without a problem, but when I get close to 3702i phone can't find either 2.4GHz or 5GHz. I've tried two individual SSIDs for each band but still phones can not detect any, no matter what channel width and combinations I try. What's even more strange, if I do the same with notebook then there is no problem, it reconnects seamlessly. And if I switch 3702i to autonomous image and set it up as a standalone unit, then both bands work just fine for phones as well.
"AP type" for all three APs is indicated as FlexConnect with vlan mode enabled and they're all wired to the same switch. I've run out of ideas how to troubleshoot further.
