Realtec card doesn't work

Hi everybody !
I have just bought an HP Laptop with Realtek Semiconductor Co., Ltd. Device d723 WIFI card and installed ArchLinux, this card looks that need the firmware rtl8723de , But I've tried to install it from this link
https://github.com/lwfinger/rtlwifi_...nded/rtl8723de and from AUR but after installing this firmware and rebooted the laptop if i try to see the network interfaces WIFI doesn't appear ... could you help me ?

You don't have to re-boot to use a new driver in Linux.

Do you have ArchLinux's firmware package installed? I use Slackware; it has a package for firmware. If you can find the relevant firmware from any source you can just put it in /lib/firmware.

I have a Realtek WiFi card that requires a driver that the kernel only builds from staging; I don't use package kernels - they may not have staging.

https://www.linuxquestions.org/quest...5552202-print/ may be useful

What does
Code:
cat /proc/net/dev
return?

Thank you for you response ! I also use Slack in the desktop

any way :

Is enp1s0 the card? If so, what does
Code:
ifconfig
return? If enp1s0 is the card, and ifconfig doesn't return an entry for it, try
Code:
ifconfig enp1s0 up
. If that works, run dhcpcd.

The kernel-firmware package has firmware for a few different r8723 chips; the kernel package has drivers for a few different r8723. What do
Code:
 locate 8723 | grep firmware
and
Code:
locate 8723 | grep modules
return?

the card Ethernet works fine .. so enp1s0 is already up as you can see and have an IP

$ ip link show

The wireless device should show up with a "w" prefix. If it doesn't then you don't have a working driver. If it does there may be additional steps to "use" it.

# rfkill list
# rfkill unblock all
# ip link set wlo1 up
# iw dev wlo1 scan
# iwlist wlo1 scanning

For my rtl8723be, there's an antennae issue. It has 2, only 1 is connected, by default it selects the NOT connected antennae.

# ip link set wlo1 down
# modprobe -r rtl8723be
# modprobe rtl8723be ant_sel=2
# ip link set wlo1 up
# iw dev wlo1 scan

Without that, I don't find any networks on the scan. It might not suit your chipset.

# iwlist wlo1 scanning
wlo1 No scan results

My other hp laptop does have the de variant, but I haven't bothered setting that up or using it. And the ethernet is even flakey on debian buster. I need to reload(unload/load) the module regularly to keep the network active. Sadly my best spec'd computer, and the least linux compatible. Well it all works, just all the networking options are flakey at best. Except for one of the many linux compatible dongles that I have (and should be using).

Installation isn't your problem: all the firmware and modules are present. You may just need to load the module. If you can't figure out which one you have, try loading them 1 at a time, then check /proc/net/dev to see if it has created a new device.

It's weird that they're only in /usr/lib/modules - they should be in /lib/modules/4.15.15 - they won't auto-load if they aren't.

The modules should be in /lib/modules/$(uname -r)/... AND the firmware should be in /lib/firmware/rtlwifi/...

For source compiles you'll need the kernel headers for the currently running kernel. Plus a make install step (as root), or you'll have to insmod the module from the point of compile with the full path and full filename. And six-ish months ago the rtl8723de module didn't even exist so it's usability might still be a bit hit and miss. Most things in linux will work out of the box, once it's two years or more older. Which is probably why I haven't bothered with it much on the one laptop that I have with that chipset.

What did it install? Something that wasn't in the package? What modules did it load? Your solution may be others'.

I don't think the de module is in the mainline git repo (yet). Probably the experimental or other port of roughly the same. The typical / traditional route need not apply (yet).
