Hello. I have an intel i5-1135G7 based laptop and i have a problem with
bluetooth. It disconnects at random once a day or so. The vendor is intel a=
nd
is connected via USB.

*-usb:3
                   description: Bluetooth wireless interface
                   vendor: Intel Corp.
                   physical id: a
                   bus info: usb@3:a
                   version: 0.00
                   capabilities: bluetooth usb-2.01
                   configuration: driver=3Dbtusb maxpower=3D100mA speed=3D1=
2Mbit/s

When it fails the message i get is:

Sometimes a reboot doesn't fix it and needs a shutdown and turn on again to
work properly.

Thanks in advance.
