--- Comment #8 from Vikash Kathirvel <master.b...@gmail.com> ---
The issue has arisen again. The only explanation for the reappearance i can
think of is i had changed location, i was out of station for a week, the usb
modem was working perfectly fine in the new location. Now i am back home and
the same problem has arisen. I don't know how this is possible.
An alternative possibility has also occurred to me, when the dongle was
working, i had no other wifi connections available. Whenever the dongle is not
working i find there are alternative wifi connections available. Coincidence?
This is the output from "nmcli --pretty -f all device show" :
