I have recently installed debian 10.9 on my system using a non-free kde image. As expected there was no wifi so I had to configure it. I got this after running lspci , 03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8723DE 802.11b/g/n PCIe Adapter . Then I found this (Iwfinger/rtw88) driver through one of StackExchange's Answers by @GAD3R. I was following the steps mentioned by him as my kernel version is 4.19, until I hit this error: modprobe: FATAL: Module rtw_8723de not found.

Steps he mentioned:

sudo apt-get update
sudo apt-get install make gcc linux-headers-$(uname -r) build-essential git

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

sudo modprobe -rv rtw_8723de 
sudo modprobe -v rtw_8723de

I think everything went well till sudo make install, and I got above mentioned error after running sudo modprobe -rv rtw_8723de.

I don't know what to do now, I really want to get wifi on my system, wired connection is unreliable for me.

I'll add the whole terminal log starting from the git clone command for better clarity.

Please also comment if need to add something more.

  • ... `Cannot stat: No such file or directory` suggests that `sudo make install` failed to install the module, thus the problem is not with modprobe--there is no installed mod for it to work on. Have you looked in to why it failed to install? – C. M. Apr 25 '21 at 07:13
  • I don't what has caused this error, most of my system is updated. Do you know, what could be the possible reasons for install failure? – Chirag Kadam Apr 25 '21 at 07:38
  • No, I do not. Please research that--Have you read the module's README file? Are you certain you have followed the build instructions (in the README) correctly? I already see the README says something specific about your card, have you looked in to that? – C. M. Apr 25 '21 at 07:53
  • I ran those commands again and this time it worked. – Chirag Kadam Apr 25 '21 at 10:47
  • There appears to be something assumed in the install script which isn't always the case. Running 'sudo make install' twice worked for me. – Brian Sep 21 '21 at 01:01
