Not able to set wifi data

Flashed my new airgradient 1 to 3.0.9 version, it fires up, presents me with the local airgradient wifi network, which I can connect my samsung phone, or tablet, to, but I see no way of inputting any wifi data for my network? The instructions say ‘if I have flashed the wifi version’ (do I need to do something more), or is there some site I need to navigate to on the device using one or other of my browsers?

OK, found solution … need to point browser at 192.168.4.1. None of my browsers go there automagically!

What specific phone do you have?

When I connect to the wifi hotspot, my Pixel 7 automatically takes me to a webpage where I can enter the wifi information for the AirGradient

Samsung tab s5 tablet, and a Samsung phone, model escapes me. They don’t seem to like being sent anywhere by a WiFi provider… Same issue when I use a hot spot at some cafe etc.
