Hi Daniel
Complicated :-)
first, brianf... said "
Web ui app on my Android Phone " so not necessarily an "App".
second, sometimes phones and phone Apps "remember" the last used settings and reuse them once discovered.
third, the symptoms - not Android Phone connection but still with the BB1/B2 radio tuner working (implying the BB1/B2 did indeed have internet connection) would indicate
a) that it may be a BT 5Ghz/2.4Ghz router issue (I did not ask that yet - 1 thing at a time)
b) that the BB1/B2's IP number has not been fixed (thought this more likely because of ("Recently had a software update on the phone and febboted the router")
Just my thinking.... could be wrong :-(
