Hi Ran into an issue while testing a setup with MR44 and Ascom VoFi Phones. Wireless-Setup was done in this basic way: DHCP: local 802.11r: off 802.11w: off Auth: WPA3 Issue: Bad connection (sporadically disconnects), roaming is working bad. -> Enabeld 802.11r -> same problem -> switched to WPA2 -> solved the problem Just as an example, my experience in the last 20years was: It's nearly always an end-device problem. Got so much trouble with "ultra fast raoming" in combination with Aironet and CCX - most of the time the clients did not support the protocol ;). So for your problem: 1. Check basic coverage, simply done with the Unify WifiMan App (Android) and check the roaming behaviour 2. Log date/time-stamps from affected clients when the disconnect happens and search Dashboard log. 3. Try to find out if it is an end-device problem of the bar-code scanner or a global problem (test with an windows notebook and walk through the area) 4. Check the APs load, if there are too many client connected/bandwith used.
