Solve Realtek RTL8XXXX weak WIFI signal problem in Ubuntu
When I switched to Ubuntu from Windows, I faced a weak WiFi signal problem, on my Linux machine. The WiFi connects to my router only when I sit next to it. I got frustrated with this and got a thought of switching back to Windows from Ubuntu. Later, I googled about this and found a solution for it.
Here are the simple steps to solve the weak wifi signal problem in Ubuntu :
Open Terminal, type below command and hit enter.
Remember or note down the wlp number. In my case its ‘wlp3s0’.
In the terminal, type below commands and press enter
sudo make install
Type you ubuntu password.
sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be ant_sel=2
sudo ip link set wlp3s0 up
Type below command to scan all available networks with strong signal strength.
sudo iw dev wlp3s0 scan
To save the setting permanently, type below command and press enter.
echo "options rtl8723be ant_sel=2" | sudo tee /etc/modprobe.d/50-rtl8723be.conf
Note: You need to apply these settings again after Kernal update, to get strong signal strength.
If the above drivers didn’t work, try downloading the drivers below.
