GPS problem - Dell Venue 11 Pro 7140 - Win 10 - internal WWAN card

Hi,

My DVP 7140 has Dell Wireless 5810e LTE mobile broadband equipped with GPS, but was never able to get GPS fix / accurate location in Windows 10 (now Anniversary Update).

Only WiFi triangulation aka Location Service gives position with 70m accuracy, but once WiFi is turned off, it's not working. It cannot be also used for car navigation or hiking.

I tried everything - different drivers, workarounds, virtual ports, wrappers, etc. to no avail.

Dell Service installed new WWAN card - no change, then asked to go back to Win 8 which I don't want.

Has anyone any success story with GPS on such platform?

Perhaps still possible to make it working?

Plsd to hear your experiences & suggestions. Dell - pls help to solve!

Cheers, Maciek
