Please note that patch you're suggesting is reworking the modem
detection, nothing to do with the actual connectivity. The missing
netifd integration still applies.
Regarding that patch; is 45s not enough in your case? If so, the
solution would be to increase the timeout, not sure about adding an
extra loop for that.
