Is the driver loaded?

hello.

#dmesg | grep "firmware|rtl" #<enter>
#lsmod | grep rtl

Code:

btrtl                  24576  1 btusb

So, try loading the wifi driver module manually...

Code:

sudo modprobe rtl8723de

Then check to see if a wireless device node is now present

Code:

ip a

Hello ferrary

#sudo modprobe rtl8723de

Code:

modprobe: FATAL: Module rtl8723de not found in directory /lib/modules/5.4.0-0.bpo.4-amd64

Anyway:

# ip a

Code:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

Thank you. I really appreciate your help.

Not sure why the module you built isn't found.

Run the following command to see if the compressed module is present as expected...

Code:

sudo ls /lib/modules/$(uname -r)/kernel/drivers/net/wireless/realtek/rtlwifi/

Assuming that the module is built, also check which compression schemes are supported by the running kernel...

Code:

zcat /proc/config.gz | grep CONFIG_KERNEL

FWIW, I've just built the wifi modules successfully in my openSUSE environment (even though I don't have this hardware), using the same instructions I gave you. We just need to find where the issue is occurring for you.

The module didn't compile so you won't have the driver.
Did you delete the rtlwifi_new directory before running the git command?

ferrari · 04-26-2020, 09:52 PM

That was back in post #25 (the OP didn't have the requisite build environment). However, going back through the thread I must admit that the OP hasn't been clear about where they are now at. I may have incorrectly assumed that they had now successfully built the required module when they actually haven't.

Maybe what you said is right,waiting for the reply from OP.

I have this wifi dongle and have to build it every time I have a kernel update. On my Xubuntu and fedora system I use dkms and it takes care of it self with kernel upodates. On my Slackware system I manually build the driver whenever I have a kerel update. When the 5.0 kernel came out the original download from https://github.com/lwfinger/rtlwifi_new/ wouldn't build, so had to Download again from the same website.
I still had the old downloaded file to check and make sure I wasn't imagining things and sure enough it wouldn't build on a 5.0 kernel. The op needs to delete the rtlwifi_new and redownload it. The op can manually download the zip file from https://github.com/lwfinger/rtlwifi_new/ if they pefer doing that instead of using the git command.

ferrari · 04-27-2020, 06:05 AM

Yes, that is what I’d hoped they had done. Anyway, best to see if they can confirm where they are at.

colorpurple21859 · 04-27-2020, 06:16 AM

for the op if you want to use dkms, install dkms if it isn't installed then as root

Code:

cd rtlwifi_new
dkms add ../rtlwifi_new
dkms build rtlwifi-new/0.6 
dkms install rtlwifi-new/0.6
modprobe -v rtl8723de ant_sel=2

create a /etc/modprobe.d/50-rtl8723de.conf and put this

Code:

options rtl8723de ant_sel=2

Hi Ferrari.

Below the outputs

#sudo ls /lib/modules/$(uname -r)/kernel/drivers/net/wireless/realtek/rtlwifi/

Code:

btcoexist  rtl8188ee  rtl8192c  rtl8192ce  rtl8192cu  rtl8192de  rtl8192ee  rtl8192se  rtl8723ae  rtl8723be  rtl8723com  rtl8821ae  rtl_pci.ko  rtl_usb.ko  rtlwifi.ko

The rtl8723de is not there.

#zcat /proc/config.gz | grep CONFIG_KERNEL

Code:

gzip: /proc/config.gz: No such file or directory

As suspected. Return to post #22 onwards.

In any case I notice that the https://github.com/lwfinger/rtlwifi_new page mentions

and

Code:

git clone https://github.com/lwfinger/rtlwifi_new.git -b extended
cd rtlwifi_new
make
sudo make install
sudo modprobe -r <<YOUR WIRELESS DRIVER CODE>>
sudo modprobe <<YOUR WIRELESS DRIVER CODE>>

*where rtl8723de is the driver name. The existing rtlwifi_new would need to be deleted first, before doing 'git clone...'

Hello ferrari...thanks. What I did was:

# git clone https://github.com/lwfinger/rtlwifi_new.git -b extended

Code:

fatal: the destiny path 'rtlwifi_new' already exist and it is not an empty directory.

So I changed the path as per git webpage as:

# git clone https://github.com/lwfinger/rtlwifi_...re/rtlwifi.git -b extendedClonando en 'rtlwifi'...

Code:

fatal: repository 'https://github.com/lwfinger/rtlwifi_new/tree/master/firmware/rtlwifi.git/' not found

So I erase the /tree/master/:

# git clone https://github.com/lwfinger/rtlwifi_...re/rtlwifi.git -b extended

Code:

Cloning en 'rtlwifi'...
remote: Not Found
fatal: repository 'https://github.com/lwfinger/rtlwifi_new/firmware/rtlwifi.git/' not found

Again, please consider me as a newcomer. I appreciate you think I am at least an amateur but I am not. Saying that, what would I do next?

Thanks in advace.

high_existence · 05-08-2020, 09:02 PM

Hi fellows.

I repeated step by step all the procedure ferrari adviced me. I (we, or you!) solved it! thank you so much. Now I am very happy with my GNU/linux Debian 10.
