Need to permanently turn off one of two intergrated Wifi adapters

Post by max32 »

Hi I'm using Mint 20.1 and have recently installed a wifi 6 AX intergrated pci network adapter in to my Asus PC and need to disable RTL8821AE pci-e permanently. There is a switch saying you can switch between the two in wireless connections although if you go into wireless settings both the pci wifi cards remain switched on at the same time. You can't choose between one or the other! I think they both conflicting and I'm getting wifi drop out. Can you help?
Secondly when I'm using my guest account (non Admin) i can easily bypass my network security by going into network settings cancelling the authentication protocol then changing what i like is that correct should that happen?
N.B Have tried to access my PC bios but it keeps on asking for a password? My PC has gone through a few software upgrades. Have found a root password that failed to work.

Maybe try going into BIOS and turning it off in there? Not sure because BIOS on every computer is different.

Let's look at your wifi setup:

Open a Terminal (Ctrl-Alt-T), copy-and-paste the following command-line, then tap Enter...

Code: Select all

(lsusb -tv; lspci -nnk;iwconfig;lshw -c network) 2>&1|nc termbin.com 9999

After a brief pause, a termbin.com URL will appear in the Terminal. Copy and post that URL in a reply.

Probably a simple uninstalling or blacklisting of the driver will do the job. But a complete hardware overview might be helpful:
- Launch a terminal window (this is how to launch a terminal window);
- Make the terminal window full screen, to avoid chopped lines;
- Copy/paste this command into the terminal:

Code: Select all

inxi -Fxpmrz
(if you type: the letter F is a capital letter, and don't omit the space after inxi!)

Press Enter.

Copy/paste the output in your next message.

Do the same with the following four commands:

Code: Select all

rfkill list all

Code: Select all

iwconfig

Code: Select all

lsusb

Code: Select all

lspci

Hi i would like to try and remove the Realtek card first before tying to use command lines. Last i looked it seemed like a complex job to remove -- do you know what i should pull first?

I believe it's integrated on the board, so not easy to remove.

I did it! Took out one screw and pulled it -- left the small board hanging because it was difficult to remove the cable connections to the two internal aerial's. Then i carefully cleaned the dust away from the internal fan surround.
Pulled the bios pc battery and reinstalled it to get some access to my bios, although here my mouse failed to work while witnessing access to the Advanced F7 selection button on the correct blue page. I moved the mouse connection to a usb somewhere else but had no joy so i quit with this bit.
I rebooted the PC and found my Firefox web page turn over is now billio lightning fast trust me - welcome AX!
Problem solved many thanks everyone.
