Bluetooth - windows dropouts

my laptop has built in bluetooth which initially worked fine on windows 10 and pired to zwift hub reliably.

I upgraded to windows 11 and had constant bluetooth drop outs.

So downgrade to windows 10 but am still having constant 10 - 15 second dropouts.

If i disable pc bluetooth and pair with samsung a10 phone then there are no issues.

one thing i did notice is that the PC bluetooth does not recognise the zwift hub it lists it as a usb device.

Any ideas on how to diagnose whether this is a windows issue or would it be worth buying seperate bluetooth usb ?
