ios 13 wifi disconnect
I've upgraded my iPhone X to iOS 13.1 overnight. Today, it cannot sustain a WiFi connection - it disconnects and after a time, reconnects constantly flip-flopping between connected to WiFi and mobile data. I have forgotten the network and re-joined it but nothing has changed. The network is on 2.4GHz and 5GHz (N/AC) bands.
How can I get the phone back to stability on the WiFi network? The router is a Cisco RV134W on latest firmware. All other devices are staying connected to the WiFi.
