Sounds like an MTU issue to me. Thanks, Dan

Been through all the ubnt forums and email support. Done a new VM and Controller install via backup conf. 4Gon suggest 5GHz APs, but hard to convince them. This is a small charity install of 5 x 2.4Ghz APs and 3 x 2.4 Ghz AP-LR that are working for Android, Windows and Macs. These *have been* working fine for iPhones and iPads. Symptom Summary iPhone / iPad iOS 12 * Will not load youtube and timeout * Loading a website via Safari will timeout * Facebook and Whatsapp work fine * Will not connect to download update from Apple Both have been taken off site and work fine via other Wi-Fi deployments. It sounds like DNS almost with the Facebook/WhatApps. I've seen the "prompting for password all the time", but it's not that. They associate OK. We supply the routers, switches and FTTC. Happy to pay for some support. Thanks, Gavin. -- -- Martin Hepworth, CISSP Oxford, UK
