iphone thinks a private wifi is public and opens the captive portal
i have 3 identical iphones 6s on ios 12.1.2
one of them when connecting to home wifi tries opens the router login page (192.168.1.254) thinking it is a captive portal, and obviously i can't connect.
additionally, under Settings-> WIFI-> if i open the SSID details under te "Automatic Access" flag i can see "Automatic Login" that can be flagged.
This doesn't appear on all other iphones! Any suggestion?
