Known Issues:

• Radio information on the AP dashboard may not load sometimes.
  Workaround:  Refresh the page in your web browser.
• Captive portal authentication does not work if Captive Portal configuration and VLAN configuration for a SSID is changed together.
  Workaround: Change Captive Portal configuration and VLAN configuration one at a time for a given SSID.
• When Client Isolation is enabled on a SSID, clients connected to same SSID fail to reach each other even though their IP addresses are added to allowed list.
• Intel AX210 client connectivity might encounter disruptions when roaming.
• Clients with the latest iOS version may fail to roam successfully when both WPA3 security and 802.11r roaming are enabled on the same SSID.
  Workaround: Do not enable WPA3 and 802.11r roaming together.
• Video streaming to multiple clients does work properly if there are more than 8 clients in a single multicast group.
• Some clients that experience connectivity issues on 5 GHz higher band channels might switch to 2.4 GHz band resulting in lower throughput.
  Workaround: Configure 5 GHz lower band channels.
• Some newer IoT devices may experience issues connecting to the AP.
  Workaround: Upgrade the IoT devices to the latest driver version and try again. If security is set to WPA3 or WPA3 Mixed, change to WPA2, and try again.
