after installing official driver CH340 for windows 10 and some restarts and reconnects, I was able to flash the esp 8266.
But now at the top of the device-setup-window is "connected, no ip" (yellow) - when i try to browse 192.168.4.1 it fails.
I run it on my home PC - did't have this issue on the MS Surface4 before.
Any ideas what it could be?
Thanks for help!
