How can i enable Web Authentication

Question

I am having challenges on my network,i m using Sophos XG v19 on my network 
 
 I have users connecting on LAN using web authentication,then i connected a Cisco AP on my network for wireless options .When you are connected on AP you can not have web authentication to Sophos hence no Network Access

Hi Tarisai, 
 Thank you for contacting Sophos Community. 
 Is the zone of AP allowed on the Device Access Captive Portal? 
 also, Have you created an Allow WAN to access DNS? Kindly see the following tech vid for reference.
