BE30000/BQ16 Pro - Devices dropping to 2.4Ghz, will not reconnect to 5Ghz

[Chris000]

Hi, fairly new system, as the subject states, many devices across all 3 APs dropped from 5GHz to 2.4, and I am having great difficulty getting them back. Essentially I have to take them offline, delete the record of the device in the offline client list, and reconnect them to get them back to 5GHz. rebooted the network, no help. A simple device reboot, which normally would work is not currently. I was running on channel 36, when this happened I noticed some interference, have switched to 161, still having the issue. Now I am back on 48 as it shows clear, devices still not switching back to 5GHz. Also kicked it down to 4Mhz band. It seems like corrupt entries in the client DB in some manner. Latest firmware across the board, happened to a Windows 11 PC, Echo devices, Ring cameras, some of these mere feet from an AP. Any thoughts?

wireless client decides when and which radio to connect to. period. And when to drop a radio connection.
For the IOT devices, see other recent threads about a specific option of IOT network preconfigured. It is intended to help with compatibility issues somewhat. i'm looking for the thread from earlier today.

New BE-98 Pro

I just setup a BE98 Pro. Stock updated firmware. The only issue was some, not all of iOT devices did not connect to 2.4. I used guest network pro and created an iOT network called Idiots under the original SSID for 2.4. As soon as I did that all of the 2.4 iOT devices that did not connect...

You can also play with MAC filtering in the AP portion of the configuration. May or may not work to blacklist (exclude) on one band and whitelist on desired.
Many have luck restricting IOTs to the 2.4 GHz band as this is all the bandwidth needed See above. Otherwise, Set WPA2 for max compatibility, 40 MHz or 40/20 or 20 MHz channel width for more stability and coverage distance.

And avoid using DFS channels if available.
