Sophos Central Wireless with Captive Portal - random automatically logout


first sorry for my english.

We use Sophos Access Points APX120 managed in Sophos Central.
Here we created a SSID with a captive portal. So the user only must acceppt the terms & conditions to get in the internet.

This works fine.

After a random time of minutes, sometimes up to 5,6 hours the devices will automatically disconnect from the SSID.
Not all devices at the same time, but one after another during some minutes/hours.
I don't unterstand why. What's the general timout of a captive portal? 

What is wrong on my Configuration?

Thank you for help.

  • We have had several but the last one was RE: 05298261 which we just gave up and closed on the basis we where going to test the access points managed through the XG rather than through central to see if this alleviated any of the issues. I haven't had time as yet and all the captive portal issues still persist e.g. ios devices often just dont re-direct to the portal, devices of all types andriod and iOS mostly just randomly disconnect and are asked to re authenticate on the portal.
