My FP3 had to go to hospital and came back with Android 10. All working fine, except it refuses to authorise one wifi network. I have a router in the house and an adapter and extender in my cabin office. It sees and connects to my router direct, but when I try to connect to the extender, a TP-link 483, it sees it, but refuses to authorise it. Other devices work fine on the extender. Any clues would be appreciated.
