Insight - RADIUS attribute bug - External Captive Portal

Hello James, welcome to the Netgear community.

Insight does just provide an administration and management framework, it's not involved on the Radius access and accounting. Once configured, all this happens direct on the wireless access points.

What Netgear AP models, and what firmware versions are in place?

Not using many APs deployed on the field with Radius - this reads to me like an issue/bug on the access point(s).

I suggest to open a support ticket via https://my.netgear.com/ by the customer, or on behalf of your customer. Unless these AP are relatively new, and are covered under the 120 days of the included initial installation support plan, or your customer has subscribed to the Extended Warranty and Support plan, or a Premium Support plan, the straight access to support goes through the Insight subscription. Depending on the market region, I found the online process troublesome, so crossing my fingers for you managing to open a ticket.

Things become difficult recently here due to community and support platform issues I'm afraid.

In case you can't find your way through the support jungle, contact JulienR via PM.

Regards
