Even I am facing the same issue. If I connect to the WiFi SSID with no internet for the first time, it stays connected. But if I connect back to it again, it disconnects immediately and connects back to the previous WiFi profile which has internet.

Similar issue, I test on Google Pixel 3 Android 10. After I call WifiWizard2.connect(SSID, true, PASSWORD, 'WPA', false), it will try to connect the no internet access wifi for a while, then switch to another wifi which has internet access. It will not keep the connection on the wifi I want.

(test on 3.3.1)

@mknnaren by the way, I found a workaround is to call disableWifi() first, then do connect(). This workaround work for SAMSUNG Galaxy A40s Android 9. Unfortunately, it not works for Google Pixel 3 Android 10.
