You’re not stupid.
just go to the “start menu”
type “add”
click “add/removed software”
search for dkms
It should have a “Remove” option if it is installed.
Yeah it’s installed
I’m going to do a little more research and if I find anything I will let you know.
Since we installed the one you said to install shouldnt it said different driver now? Not rtw_8822be?
This is info what I got right now:
Device-1: Realtek RTL8822BE 802.11a/b/g/n/ac WiFi adapter driver: rtw_8822be
IF: wlp7s0 state: down mac: 96:76:a8:1d:37:bf
In any case huge thanks for helping! I appreciate it alot!
I found a link but the forum isn’t letting me post it again.
Basically, this specific card has two antenna and can old use one. You have to use commands to tell it which one to use.
I will try and copy/paste the required commands.
- Some HP laptops with the Realtek WiFi chipset card RTL8723BE have just one antenna on that card designed for two (stingy HP, anyone?). This has caused many problems for Linux users, as the default antenna is usually the missing one…
But thanks to Larry Finger and the good people at Realtek you can do some testing with a module parameter that allows for antenna selection. As follows:
a. Launch a terminal window.
b. First unload the currently active module with this command
sudo modprobe -r rtw_8723be
Press Enter. Type your password when prompted. In Ubuntu this remains entirely invisible, not even dots will show when you type it, that’s normal. In Mint this has changed: you’ll see asterisks when you type. Press Enter again.
c. Then reload it with the instruction to use antenna number 2, with this command:
sudo modprobe rtw_8723be ant_sel=2
Press Enter.
d. Then check the signal strength with this command:
iwlist scan | egrep -i ‘ssid|quality’
Press Enter.
e. Then test the the other antenna (number 1), to find out which one has a stronger signal. For this, execute the following three commands:
sudo modprobe -r rtw_8723be
sudo modprobe rtw_8723be ant_sel=1
iwlist scan | egrep -i ‘ssid|quality’
f. If ant_sel=2 gives the best signal (which is usually the case), do this
echo “options rtw_8723be ant_sel=2” | sudo tee -a /etc/modprobe.d/rtw_8723be.conf
Reboot your computer.
*If ant_sel=1 gives the best signal (unusual, but not impossible), do this (this is one line, [use copy/paste]
echo “options rtw_8723be ant_sel=1” | sudo tee -a /etc/modprobe.d/rtw_8723be.conf
Copy and pasted from websiteI replace with rtw_8822be correct? Since rtw_8822be is my chip
Also iwlist scan | egrep -i ‘ssid|quality’ command doesnt work, it doesnt recognize ssid/quaility commands.
It asks username for github when i type git clone. Do I have to register?
Try the download ZIP option on github instead and then unzip it to your desktop and open a terminal in the folder.
Then follow the guide
Nope, it doesn’t work. I guess my laptop wifi card doesnt like linux. Dont understand tho, in Live, before install it worked
It’s fine, I guess ill use usb tethering… Thank you in any case for help and sorry we didnt found solution for it.
It’s okay. I enjoy learning more about linux.
Maybe someone else will pop on here later and help some more. Ill continue to do research though.
Try this command:
mhwd -lh -d --pci
Then, copy the information for your network card here.

I dont know why it says ethernet but in one place there is WiFi written
Now try:
sudo mhwd -a pci free 0200If that doesn’t work
sudo mhwd -a pci nonfree 0200Tried first one, rebooted still nothing. Tried nonfree and this shows up:

Okay, I think we’re on to something.
Go to the “#### Option configuration” section of the silenoth github link I gave you earlier.
Follow the directions for creating the config file.
