BCM943602CS location services don't work

I recently upgrade from a Tp-Link WDN4800 to a BCM943602CS. Initially BT didn't work well and other services too, now I have WiFi, BT, handoff, continuity, airdrop all works very well.

Unique problem: location. Weather location and Maps location, as the location in browser (google maps) 90% of the time don't work. What could be the reason?
