I just realize you need to remove the underscore in the card name

options rtl8823be ant_sel=1

So I tried all of them, and different ways but nothing.

[pavels@pavels-workpc ~]$ sudo iw dev $DEVICE scan | egrep “SSID|signal|(on”

Here u can see I tried 1 and 2 value. Also with that vim too

47

Did you try it without the “_” in “rtl_8822be”

Also, you typed “rtw” not “rtl”

48

you can also try omitting the 50 from the file name

and the _ is supposed to be - in the file name

So,

sudo vim /etc/modprobe.d/rtl8822be.conf

or

sudo vim /etc/modprobe.d/50-rtl8822be.conf
49

I apologize, I know this is frustrating.

50

I tried with rtl but it said doesnt exsist and from somewhere I remembered that I used rtw_8822be not rtl8822, tried and it worked. When I tried to install at the start it didnt recognize as rtl but as rtw

Na its not fustrating at all

51

Okay, I am going to type a list of commands in the next comment.

Just copy and paste in the order that I give.

52

Okey, will do that. Probably I am doing something wrong xD

53

Consider this the “nuclear option”:

sudo su
sudo vim /etc/modprobe.d/rtl8822be.conf

enter “options rtl8822be ant_sel=1”

sudo vim /etc/modprobe.d/50-rtl8822be.conf

enter “options rtl8822be ant_sel=1”

sudo vim /etc/modprobe.d/rtw8822be.conf

enter “options rtw8822be ant_sel=1”

sudo vim /etc/modprobe.d/50-rtw8822be.conf

enter “options rtw8822be ant_sel=1”

sudo vim /etc/modprobe.d/rtw_8822be.conf

enter “options rtw_8822be ant_sel=1”

sudo vim /etc/modprobe.d/50-rtw_8822be.conf

enter “options rtw_8822be ant_sel=1”

exit
54

If that doesn’t work, change all the 1s to 2s

55

With “” or without “”?

56

Without

57

Tried with 1s and 2s and still nothing. Says:

[pavels@pavels-workpc ~]$ sudo iw dev $DEVICE scan | egrep “SSID|signal|(on”
command failed: Network is down (-100)

58

Okay, I am sorry, but I think I have hit the limit of my knowledge on this subject.

You may want to go into /etc/modprobe.d/ and delete all of the files that you created except whichever one you think is the right one.

Then, maybe someone else can find this and help you more.

59

Okey, no worries. Thank you for your time! I appreciated it alot even tho we did not find solution. :wink:

For anyone wondering, the solution ended up being adding the following to /etc/modprobe.d/blacklist.conf

blacklist btrtl
blacklist btusb
blacklist r8822be
blacklist rtw88
blacklist rtwpci

Also, deleting all the extra files we created earlier around the same time probably helped as well.
