BLE dropping in and out with Mobile link (Scosche HRM, KICKR Snap, Ridesense RPM/Cadence)

Hi, have seen some old posts about this, but out of the blue after weeks of no problems with bluetooth devices, all of a sudden I’ll be in the middle of a ride and see my power, HR, etc., all go to zero.  It keeps coming in and out. 

Interestingly if I switch to ANT+, everything is fine, so that’s what I have done today, but still I had been using bluetooth without issues previously.

Any thoughts?  I did update my setup so I am now using my son’s “old” Alienware 15 R2 laptop connected to a monitor and then use mobilelink for my bluetooth connectivity through IOS.
