Hi,

Ubuntu 18.04 has the RTL8723DE firmware available. You have to install from software repository. Package name is "linux-firmware". Make sure all repositories (Bionic-updates etc) are enabled.

 

:~$ sudo apt update
:~$ sudo apt autoclean
:~$ sudo apt install linux-firmware

Which model is your laptop (with model number). I believe, you already have wireless up?

@Ashish_Nagdev: I have the same laptop - HP 15-BS576TX (2EY73PA#ACJ) with hybrid graphics. It is working well for me, so should be for your laptop also. I have to configure amdgpu drivers using the  "pkppa" which carries latest MESA and DRI for the AMD R 520 dedicated graphics card. Then, the RTL8723DE wireless module drivers for this laptop. Rest, everything is functioning fine.(If you are interested, I can tell the steps including kernel options I've used for configuring amdgpu driver, you can create a question and tag me there)

 

The wifi signal reception in this laptop only improves with ant_sel=2 option. So, as explained in the first post, you have to create a file in /etc/modprobe.do/rtl8723de.conf with above option. Otherwise, Wifi reception is less, just like in Windows 10 (I dual boot with Windows 10 ).

 

Do this first:

You have used "git" command to pull the rtlwifi drivers, I believe. This git repository got updated, once in a while. (Make sure you are connected to internet). So go to the rtlwifi_new directory - Open a terminal and run:

git pull

Then, do a :

:~$ make clean
:~$ sudo make install

 

Now, the problem:

The false identificaiton of rtl8723b  as the driver happens because of 2 reasons:

1. Kernel version is less than 4.17, which is not your case. Still, I will recommend you make sure have 4.18 mainline kernel from ppa - https://www.fossmint.com/ukuu-install-and-upgrade-linux-kernels-in-ubuntu/

 

2. Firmware files missing - These files must be in the following directories. Check and verify that these firmware files exist.

 

/lib/firmware/rtl_bt/rtl8723d_config.bin

/lib/firmware/rtl_bt/rtl8723d_fw.bin

/lib/firmware/rtlwifi/rtl8723defw.bin

Also, since the firmware for rtl8723de is carried in the linux-firmware package, just re-install in case something is missing.

:~$ sudo apt update && sudo apt install -y --reinstall linux-firmware && sync

And ..reconfigure linux-image-(your version)

:~$ sudo dpkg-reconfigure linux-image-your-version

3. Make sure you have installed Ubuntu 18.04 in UEFI mode -

   Boot into BIOS menu - check that legacy mode is disabled, SECUREBOOT is disabled.

 

  Open a terminal and run:

[ -d /sys/firmware/efi ] && echo UEFI || echo BIOS

 

if the result is UEFI, it is OK.

 

 

Hope this helps. I will try to get a newer kernel as the first step. Make sure kernel, kernel-headers installed.

 

 

I'm going a little offtopic here - If you still find step (1) difficult - Download all these files to a new directory - say "deb-files" in your Downloads folder:

linux-headers-4.18.5-041805_4.18.5-041805.201808241320_all.deb
linux-headers-4.18.5-041805-generic_4.18.5-041805.201808241320_amd64.deb

linux-image-unsigned-4.18.5-041805-generic_4.18.5-041805.201808241320_amd64.deb

linux-modules-4.18.5-041805-generic_4.18.5-041805.201808241320_amd64.deb

 

Open a terminal inside "deb-files". You may know.

Then, do a:

:~/Downloads/deb-files$ sudo dpkg -i *.deb

This will install the current (29/08/2018) version of Linux kernel for Ubuntu 18.04 from kernel mainline ppa. Boot with this kernel and build the wireless modules as told in the first step (after git update).

@COE2k14 Thanks for the detailed response!

 

However i tried all steps earlier and re-verified it again but still its not working. Just one difference is i have installed ubuntu in BIOS mode

 

:~$ [ -d /sys/firmware/efi ] && echo UEFI || echo BIOS
BIOS

 

 

Will this impact? If yes can you let me know how to switch over to UEFI.

 

Thanks!

Thanks for the manual, I installed the driver, the rtl8723de network card works, but sometimes there is a problem on the HP 15-bw026ur laptop. When I reboot the OS, Linux does not see the network card, as if it is disabled. As a result, you have to turn off the laptop, remove the power, and then turn on the laptop, then the card turns on. Installed the latest firmware F.40 but it did not help.

Sorry it not work on fedora29, seems many people are using Ubuntu. Fedora is out of the game?
