I am using a HP ENVY Laptop 17m-cg0xxx with the AX201 chip. As the title says my bluetooth's range is too weak. So weak that it only goes about 5 to 6 centimeters from the laptop.
I have tried everything from updating my kernel to the 6.5.0-17-generic to try different firmware directly from the linux kernel archives. And copied ibt* and iwl* firmware files into /lib/firmware and /lib/firmware/intel respectively.
So I am wondering if somebody has a sollution for this. Maybe a specific firmware version for this specific chip.
I have seen similar questions to mine but about the wifi. My wifi works fine.
