how to stop: when turning on bleutooth, it turns on airplane mode.

Asked by michael

My computer does not have bluetooth. I put a Asus USB-BT500 (Linux compatible) dongle in. When I turn bluetooth on, it puts it in airplane mode, which shuts bluetooth off. How to fix?

Dell Inspiton-620
Ubuntu 20.04.5 LTS
Intel® Core™ i5-2320 CPU @ 3.00GHz × 4
AMD® Caicos Graphics
3.0TB disk capacity
3.36.8 Gnome Ver.
Ubuntu 18.04, 20.04, 22.04 triple boot
Wired connected - 100 Mb/s
5.8 GiB memory
Have turned on most bluetooth related packages in Synaptic Package Manager

Thanks

I forgot to say, first thing I did was to download Linux drivers from Asus.

Do you think I should apply their solution?

cd /lib/firmware/rtl_bt
sudo ln -s rtl8761b_config.bin rtl8761bu_config.bin
sudo ln -s rtl8761b_fw.bin rtl8761bu_fw.bin

Did not help, still the same.

first line
cd /lib/firmware/rtl_bt Gave me this,

michael@michael-Inspiron-620:/lib/firmware/rtl_bt$

I could not get #4 lines in. I tried to put in line by line. Terminal would not take second line.
I tried all three lines together, terminal would not take.
How to get the three lines into terminal?

Read farther down post. Tried removing dongle. Not good.

THIS is a MESS now. Will stop tonight, comeback tomorrow. Will reload drivers.

Thank You for your help.

I re-downloaded Linux drivers from Asus site. One picture below says searching for devices. The dongle is in. Any ideas?
