This is my First Question in the form.

I have an hp-ac122tu laptop with realtek NIC.

I can connect to all Wi-Fi routers and my Android hot-spot without any problem( Except Network manager won't refresh until restart). But this particular Wi-Fi modem is not being detected by Ubuntu and Other Linux distro while my WIndows 10 and all other devices can connect to it hassle free.

Now How do I fix it? Any helping hand is appreciated.

Right now I'm using Wi-Fi by tethering my Android device.

Since not being able to get a proper solution from here I went on and took the risk of downloading a driver from gitub and manually installing my realtek driver.

type this in your terminal window

$ iwconfig

and found out my wifi's name. wlp13s0

https://github.com/lwfinger/rtlwifi_new/tree/rock.new_btcoex

went to this link and downloaded the zip file (clone). put it in the desktop and change directory using commands

$ cd Desktop

and extracted the file on desktop

$ cd rtlwifi_new-rock.new_btcoex

$ make && sudo make install && sudo modprobe -rv rtl8723be && sudo modprobe -v rtl8723be ant_sel=2 && sudo ip link set wlp13s0 up

THe last command is supposed to turn n wifi so just in case it doesn't work , manually turn on the Wi-Fi

and

$ sudo iw dev wlp13s0 scan

and THere my Wi-Fi hotspot name was listed.

$ echo "options rtl8723be ant_sel=2" | sudo tee /etc/modprobe.d /50-rtl8723be.conf

to save the current configurations into the file.

Restarted my system. and Wi-Fi is normal and working all well.

another way is to change the tx power which is risky so I skipped.

In case anyone have the same problem with realtek linux drivers, follow these steps.

Note: For installing it in kali linux you will need to have latest kali release and kernel.
