Suddenly all our Apple devices do not connect to our Wi-fi. It keeps saying wrong password but other household devices are connecting fine.
I have restarted all devices including the router, and reset my network settings on my phone but all this has done is stopped me connecting to my Wi-fi as a “hotspot”
A factory reset of the BT Home hub, normally fixes most problems. Its not unusual for the home hubs to "forget" devices. MAC address randomisation makes this more likely, as each new MAC address needs to be allocated a new LAN IP address, and eventually there are no more addresses left.
