RTL8822BE without bluetooth and disconnections on HP Laptop

Hi guys,

I'm having problems with the bluetooth adapter. I recently bought an HP Laptop 15-dw0052wm and I've installed Archlinux. The first problem is that bluetooth adapter is missing, I tried to use the lwfinger/rtlwifi_new firmware (rtw88 branch) but that had no effect. The second problem is that when I'm downloading a large file, the modem gets stuck and then reboots.

I'm using this kernel:

5.5.9-arch1-2

This is my lspci -k output:
