Dell precision 5510 Bluetooth and wifi issue

Hello, I'm using Dell precision 5510 workstation, when I connect my bluetooth headset .. my wifi connection is very unstable, I've changed my wifi modem settings to 802.11b/g/n to 802.11b/g but it's not helping!
I've already updated my network and bluetooth drivers to the latest (20.10.1.1190) .. still didn't solve this interference issues.

Thanks in advance
