Hi Admin,
It is a home built but has the later Raspberry PI and the latest Radio bridge.
Tried with my iPhone, O.K. no Password, Says incorrect password if password set and will not connect.
System works and has been working for over a year with no password.
If I am the only user with this problem it must be a hardware problem, Raspberry PI, Radio Bridge or WiFi Dongle.
I have ordered another WiFi dongle, being the cheapest item.
