Hi everyone.
I'm (well - I was) connecting to internet using USB 4G modem: ZTE MF821. Was trying resolve some minor network problem and performed "Network reset". After that I reinstalled software fir my USB modem and since then I can't connect to the internet.
Before I had no problems with connection but now doesn't mater what I'm trying to do I can't get access to the internet.
I'm attaching some screenshots to get you better understanding of issue.
