The Netgear AC341U seems to delay reporting packet service status
indications or actually not even send them. This leaves us with modems
in connected state in ModemManager but actually disconnected. We can
detect this situation by actively polling ourselves the connection
status.
See e.g. this case where the indication is received 2.5 mins after the
first OutOfCall error detected when loading statistics.
