New setup of 1852e access points in production area using 802.1x authentication to Windows NPS server, machine certificates.
Also have printers connecting with NPS user name and password.
Computer clients authenticate and connect fine. The problem is, viewing monitoring of clients, after about an hour to an hour and a half, they disconnect and re-authenticate. So the list is full of computers being connected for 30 seconds, 28 minutes, 1 hour 14 minutes, etc. Net sh wlan report shows the reason as "The network is disconnected because the user wants to establish a new connection".
After searching all settings and GPO settings for the Wifi profile and finding nothing wrong, checked one of these computers in the lab that is connected to a different Wifi access point. Same GPO, Radius profile, SSID, etc., just a different access point instead of one of the Ciscos. The client still has Unifi in the office areas. Check the controller and this computer has been connected for over 4 days.
So, it appears this is not initiated by the client after all.
I have disabled optimized roaming on 2.4 and 5 Ghz as I couldn't find any docs on changing the threshold level.
This is a new installation of 8 1852e access points, have been running for a couple of months and have been in full production use about a week. Client is having issues with disconnects to their web app used in their production process, causing issues.
Happens on both 5 and 2.4 Ghz radios, and on the strongest signals (-48 dBm) along with the weakest ones (-68 dBm). The clients are stationary - they aren't roaming between access points.
Set 5 Ghz down to 6 mbs min data rates and 2.4 to 12 mbs.
One change is that after disabling optimized roaming the Zebra printers connecting via user name and password are staying connected for 4 and 5 hours now.
The computers are Lenovo m720q with Intel Dual Band Wireless-AC 8265 which are AC Wave 2.
Power settings are set to maximum performance for the adapters.
Hopefully someone can provide direction as it isn't too good that I recommend Cisco equipment to replace Unifi and the Unifi provides a more stable connection.
Running the latest firmware.
Thanks.
