Known Issues:
- Facebook Wi-Fi authentication does not work because Facebook has discontinued the support for this feature.
Workaround: Use the Instant Captive Portal feature or the basic Captive Portal feature. - The captive portal splash page might display the error message "ERR_TOO_MANY_REDIRECTS" while connecting to a captive portal that is enabled on an SSID.
Workaround: Clear the browser cache. - 802.11r roaming does not work between an AP that runs firmware version 10.5.0.x and another AP that runs an older firmware version at the same Insight network location.
Workaround: Upgrade all APs at an Insight network location to the latest firmware version. - The AP stops responding after you first change or enable an Instant Captive Portal and then change or enable a dynamic VLAN (DVLAN) configuration, or the other way around.
Workaround: After enabling the Instant Captive Portal, wait a few minutes before you enable the DVLAN configuration. Or, after enabling the DVLAN configuration, wait a few minutes before you enable the Instant Captive Portal. - Clients connected to a captive portal that is configured on an SSID might not see the splash page for authentication when the VLAN of the SSID is the same as the management VLAN, a VLAN that is configured as a DVLAN, or a VLAN that has a multi-Pre-Shared Key (multi-PSK) configured.
Workaround: For the SSID on which the captive portal is configured, use the default VLAN or a unique VLAN that is not used as the management VLAN, that is not a DVLAN, or that does not use MPSK. - A MAC ACL might not work as expected when MAC randomization is enabled on a WiFi client.
Workaround: Disable MAC randomization on the WiFi client. - 802.11r-based fast roaming fails for a Samsung Galaxy S10 client that is connected to an SSID that has WPA2 enterprise security enabled if the Protected Management Frames (PMF) feature is also enabled.
Workaround: Disable PMF. - An Instant Captive Portal does not work for clients that are connected to an SSID with OWE security. This situation might occur on an AP that is newly set up.
Workaround: Reapply the captive portal configuration from Insight. - Issues might occur with Insight Instant Mesh WiFi, causing the AP to operate on a non-optimum channel.
Workaround: Configure the AP to use a static channel. - Client connectivity and throughput-related interoperability issues might occur on a WiFi device that is running a Windows, Android, or iOS version when WPA3/WPA2 Personal security is enabled on the SSID.
Workaround: Update the WiFi device to the latest available Windows, Android, or iOS version, and update the device’s WiFi client to the latest driver. - Interoperability issues might occur with certain clients when band steering is enabled.
Workaround: Disable band steering. - The pop-up login screen might not display for clients that are connected to an Instant Captive Portal SSID.
Workaround: Launch a web browser and enter the URL for the captive portal authentication page in the browser’s address field. You can also open http://NeverSSL.com, but using this URL to connect to the SSID doesn’t provide encryption and good authentication. - Certain special characters are not supported in the SSID name of an Instant Captive Portal.
Workaround: Do not use special characters in the SSID name. - After updating to a newer firmware version, the local browser user interface (UI) might not show the latest changes.
Workaround: Clear the web browser cache. - WPA3 personal security and WPA3 enterprise security do not work with an iPad mini.
Workaround: Configure WPA3/WPA2 personal security.
