I have installed an Ubuntu 20.04 on umax notebook and I cannot found any working driver for 0bda:d723 Realtek Semiconductor Corp. 802.11n WLAN Adapter.

lsusb shows me the device, but I cannot found any wifi network adapter

I have tried ndiswrapper but it not worked for me: Ubuntu 20.04: I cannot compile latest ndiswrapper

I have tried other solutions from here (with similar wifi card): Installing Wi-Fi driver for Realtek Semiconductor RTL8723DE Device [10ec:d723]

    sudo dkms install rtl8723de/5.1.1.8_21285.20171026_COEX20170111-1414

Is there any working driver in ubuntu 20.04?

Since you have tried several other drivers previously, this assumes that you have installed all of the prerequisites.

With a working internet connection by ethernet, tethering or whatever means possible, open a terminal and do:

git clone https://github.com/lwfinger/rtw88.git
cd rtw88
make
sudo make install
sudo modprobe rtw_8723de

You will need to disable Secure Boot.

This driver must be reinstalled every time that Update Manager offers a newer kernel version. After the requested reboot, with a temporary internet connection by ethernet, tethering or whatever means possible, do:

cd rtw88
make clean
git pull
make
sudo make install
sudo modprobe rtw_8723de

Your wireless should be working again. Please retain the rtw88 file and these instructions for that time.

  • seems not to be working, I see a following message in my journalctl: rtw_core: module verification failed: signature and/or required key missing - tainting kernel – Dániel Kis Dec 29 '21 at 17:09
  • Be certain that Secure Boot is disabled and show us: sudo dmesg | grep rtw Did you try a reboot? – chili555 Dec 29 '21 at 17:21
  • I have disabled secure boot and rebooted my computer. Output of the command:

    [ 371.544458] rtw_core: loading out-of-tree module taints kernel. [ 371.544633] rtw_core: module verification failed: signature and/or required key missing - tainting kernel

  • I reenabled the secure boot, now I get other error message: modprobe: ERROR: could not insert rtw_8723de: Operation not permitted – Dániel Kis Dec 29 '21 at 18:03
  • Please reboot and show us: lsmod | grep rtw and also: sudo dmesg | grep 8723 – chili555 Dec 29 '21 at 21:47
  • lsmod | grep rtw gives empty result. dmesg output: [ 4.963605] Bluetooth: hci0: RTL: examining hci_ver=08 hci_rev=000d lmp_ver=08 lmp_subver=8723 [ 4.964593] Bluetooth: hci0: RTL: loading rtl_bt/rtl8723d_fw.bin [ 4.966893] Bluetooth: hci0: RTL: loading rtl_bt/rtl8723d_config.bin – Dániel Kis Dec 29 '21 at 22:10
  • The driver did not load. Please again disable Secure Boot and try again: lsmod | grep rtw and also: sudo dmesg | grep 8723 Please keep Secure Boot off if you need this wireless. – chili555 Dec 29 '21 at 22:37
  • Above mentioned logs are made when secure boot was disabled. – Dániel Kis Dec 29 '21 at 22:40
  • Let us continue this discussion in chat. – chili555 Dec 29 '21 at 22:44
  • This can't work, it's for RTL8723DE, not author's RTL8723DU – R A Jun 18 '23 at 18:17

You need a different driver, in terminal check mokutil --sb-state as Secure Boot needs to be disabled for the driver to load, then in terminal

sudo apt install git dkms
git clone https://github.com/lwfinger/rtl8723du.git
sudo dkms add rtl8723du
sudo dkms install rtl8723du/0.1

Reboot

Ok there is an issue with the dkms.conf that causes problems, so do sudo dkms remove rtl8723du/0.1 --all and sudo rm -r /usr/src/rtl8723du-0.1 Then go into the rtl8723du directory in your home directory and double click on dkms.conf and paste this in

PACKAGE_NAME="rtl8723du"
PACKAGE_VERSION=0.1
MAKE="'make' all KVER=${kernelver}"
CLEAN="make -C $kernel_source_dir clean"
BUILT_MODULE_NAME[0]="8723du"
DEST_MODULE_LOCATION[0]="/updates"
REMAKE_INITRD=no
AUTOINSTALL=yes

Save and exit, then do in terminal

sudo dkms add rtl8723du
sudo dkms install rtl8723du/0.1

Reboot if no errors

  • I get a following error message:

     – Dániel Kis Dec 30 '21 at 22:07
  • ok, try cd rtl8723du && make && sudo make install then reboot – Jeremy31 Dec 31 '21 at 13:26
  • https://termbin.com/838a – Dániel Kis Dec 31 '21 at 15:41
  • Compiled without error messages, but It slow down the system after reboot. In journalctl there are lot of timeout entry: failed to activate service org.freedesktop.RealtimeKit1: time out (service_start_timeout=25000ms). Therefore firefox not starts. – Dániel Kis Dec 31 '21 at 19:02
  • See https://askubuntu.com/questions/425155/my-wireless-wifi-connection-does-not-work-what-information-is-needed-to-diagnos and run the wireless script, then do cat wireless-info.txt | nc termbin.com 9999 and post URL – Jeremy31 Dec 31 '21 at 20:01
  • I have to reinstall the ubuntu, because the system slows down, network, and network related commands are frozen. After installation I run the above mentioned command, result can be found here: https://termbin.com/i9lv – Dániel Kis Jan 03 '22 at 13:09
  • I need the results after the driver is installed to see if some part of the driver is causing it – Jeremy31 Jan 03 '22 at 14:19
  • cd rtl8723du && make && sudo make install this works in case thanks You So Much,,, DKMS was giving same error to me – Adarsh Raj Oct 24 '22 at 02:03

kablosuz ppa has the necessary drivers:

mokutil --sb-state # check the output for "SecureBoot disabled", disable Secure Boot if not present

sudo add-apt-repository ppa:kelebek333/kablosuz
sudo apt update
sudo apt install rtl8723du-dkms


reboot the computer here


sudo modprobe 8723du
