Hi all, So we tried bluetooth off. No luck. Bought a new 5GHz - https://www.ui.com/unifi/unifi-ap-ac-lite/ with cloud key and it didn't work. They took that home and tested on a Sky router and it worked with the same iPhone (awaiting make/model and settings). Seems to be our network then. Where this works on my own set up, it is BTW FTTC. This set up is via our TTB FTTC links, same MTU though of 1492 for all FTTC links. I'm going tomorrow with an iPhone 8 with the new iOS 13.1 on it to test that has never seen this network. There is a pair of SRX220H2s there and at home is a SRX100H2, same settings and controller versions and disc firmwares. No URL filtering or anything like a Juniper KB points to: https://kb.juniper.net/InfoCenter/index?page=content&id=KB29239 Any other ideas? Will report back. Thanks, Gavin.
