I recently bought a HP-BW088AX Laptop from Amazon. I initially installed Kali Linux on it because I wanted to learn penetration testing and hacking, but as I was new to Linux I decided to go for a more user-friendly distro. So I dual booted my laptop with Ubuntu.
After I installed Ubuntu I had to face some issues with the inbuilt wireless card. I had faced similar issues with Kali Linux but I got them solved.
The problem was that the OS wasn't detecting the inbuilt wireless card which is a Realtek RTL8723DE chipset. I installed the drivers for it from here RTL8723DE Drivers, consequently the wireless card was detected but the signal was very weak. So I started finding a solution on the internet and I found this : Weak Wi-Fi Signal in Ubuntu
Output of lspci:
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device d723
This solution worked for Kali Linux which is also a debian based distro but the same is not working for Ubuntu. But it is not working in Ubuntu. Everything works fine until I run this command :
sudo modprobe -rv rtl8723de ant_sel=2
I get the following output :
modprobe: FATAL: Module ant_sel=2 not found.
I didn't face this issue in Kali Linux.
- I have Ubuntu 18.04.02 LTS.
- Processor : AMD® A9-9420 radeon r5, 5 compute cores 2c+3g × 2
- Graphics : AMD® Stoney
- GNOME : 3.28.2
Any help would be appreciated a lot. Thanks in advance.
