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:

Re: RTL8822BE without bluetooth and disconnections on HP Laptop

I faced exactly the same problem. Have you found a solution for her?

Re: RTL8822BE without bluetooth and disconnections on HP Laptop

04:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTL8822BE 802.11a/b/g/n/ac WiFi adapter
	Subsystem: Lenovo ThinkPad E595
	Kernel driver in use: rtw_8822be
	Kernel modules: rtwpci, rtw_8822be

Got the same adapter. It' s a crappy one for linux based systems. I've got my laptop working with somewhat stable wifi and bluetooth using the lts kernel. As you can see I've been trying out the two relevant modules.
This package (aur) seems the more stable one.

rtw88-dkms-git r13.a173c84-1

Kernel

5.4.58-1-lts

Once I've got some time, I will see if I can swap the realtek for a intel adapter. Needs some thorough investigating though.

Re: RTL8822BE without bluetooth and disconnections on HP Laptop

Thanks for the answer. So you have an RTL8822BE network adapter and bluetooth works in it on Linux?

Re: RTL8822BE without bluetooth and disconnections on HP Laptop

Yep! There are some ideas floating around about power managment on the www, but I just think that it's a driver issue and it's just realtek's fault.
I went over to the lts kernel because kernel 5.8 gave me (already reported) issues with bluetooth (seemingly not realtek related). Using that kernel on my two (work)laptops and feel fine about it.

Well.. did you check out the bluetooth wiki (probably did), and besides that it's interesting that your internet connection goes crazy downloading stuff. Did you use google on that?

Re: RTL8822BE without bluetooth and disconnections on HP Laptop

Yes watched the wiki and used google. Installed the LTS kernel version and rtw88-dkms-git r13.a173c84-1. Does not work. I'm desperate.

Re: RTL8822BE without bluetooth and disconnections on HP Laptop

I think the answer to my question is on this site www.https: //github.com/lwfinger/rtw88. I will be happy to help me figure out if what is on this page will help me and if so how to install it correctly and in what order.

Please use the edit button to append information to your last post instead of posting twice in a row.
You can also use the edit button to fix the URL in your post so that it appears as a link: https://github.com/lwfinger/rtw88

I'm assuming that the report that you filed with the content of your previous post was an accident so I am ignoring it.

Re: RTL8822BE without bluetooth and disconnections on HP Laptop

https://aur.archlinux.org/packages/rtw88-dkms-git

i'm pretty sure that what you found on github, is exactly what above aur package is taking care of.

Upstream URL:    https://github.com/lwfinger/rtw88 from the aur. You could post a question in the aur comment section for that package.

Maybe post this output

lsmod | grep rtw
