WiFi and Bluetooth fail on Ubuntu 19.10

Question

I just tried a new pair of ear pods connected via Bluetooth to my MacBook Pro (early 2011), where I run Ubuntu 19.10 . The WiFi connection stopped working properly, with about 42% packet loss.

I've tried @Pilot6's suggestion:

sudo tee /etc/modprobe.d/iwlwifi-opt.conf <<< "options iwlwifi bt_coex_active=N"

...and @Buried Alive (Here's the link tot he post: wi-fi and bluetooth not working simultaneously) (what a nickname), but none of theirs worked.

Anybody else who may know if there is a solution to this?

Here's the output of lspci -knn | grep Net -A3; lsusb:

PS: I cant get it connected to another Bluetooth device and have both connection working simultaneously, what might suggest that the problem is with the ear pods, but it works just fine with a Sony Vaio computer, also running Ubuntu 19.10.

Any attempt to help is appreciated.

Cheers, A
