I had the same problem right after getting radius enabled and captive portal set up. I created a new user, ticked Radius, and clicked submit, tried to log into the portal as the user, and it wouldn’t work. I fixed it by going back into the user’s account, saw that it was not ticked, like yours, I ticked it anyways, clicked submit, and radius worked, and was able to log into the portal, and WPA worked for wireless.
