I am not a Dell employee
I am also having this same exact issue, but with a new Samsung Galaxy S10e from T-Mobile and a Dell XPS 9560 with the Killer Wireless/Bluetooth combo card installed by Dell at time of purchase. All drivers are up to date via Windows updates and Dell's own software. Running Windows 10 Professional also pre-installed by Dell at time of purchase.
Phone also has it's latest firmware updates.
