Hi Arūnas,

The images didn't seem to show correctly, are you able to email directly? to

Which build of win10 do you currently have?

Do you have any outstanding/pending windows updates still to be installed? If so let the updates all finish firstly and restart PC. Take the dongle out, and plug it into a different USB port if possible. See if that will help windows connect to the dongle again correctly.
