Thanks for the detailed response Jughead, again if I am off track please correct.
Wifi Utility (1702.1)
Must have active internet connection. (Correct, but only to access cloud services.)
PC Software (1707.2)
Wifi to PC (tools/setup switching) for diagnostics, need active internet connection. (at least I can't make it work without) (Need active wifi but internet connectivity not required as all software required is built into the application)
Ok I figured out you have to be in D2D mode and select the GS911 in network settings.
And Yea no cloud services in the utility (i.e. abs service functions)
If a user had a shop with no internet ( as one poster claimed) then he would need usb, and only the PC software with less then full function would be available. (As long as there is an active wifi network, the PC app can be used and will provide 99% (?) functionality)
In the PC app I can't seem to find anything that doesn't function but then again I didn't go through "everything" and test it all.
This certainly helps as when I tour I carry a full win 10 mini laptop with me and will have better service capabilities then with just a smartphone app when I have no internet access in foreign countries while on the road.
