This one is still going strong.
Today I was testing with our SQ6, came back from maintenance yesterday. Together with a new router, all set up well. I know my networking in this way.
SQ6 has the 1.5.9 firmware.
My iPhone 8 with SQ4YOU 1.5.1 won’t connect to the console. Not with the IP-address set up manually nor with the autodiscover of the app.
My iPad mini 3 with SQ4YOU 1.5.0 will connect to the console.
Both connect to the wireless without any hassle, no further settings have to be made on the router. It’s between console and app, can’t explain differently.
