[SOLVED] problem with wifi driver

[tony37]

@ Factral: That's nice, that was the other driver I wanted to try. But maybe it was just "rfkill unblock all" that did the trick but with all this blacklisting back-and-forth, your kernel driver wasn't active then?

I've done it, and the only thing it does is the bluetooh, it still can't connect via wifi.

you don't need any of these drivers to have bluetooth, trust me (as rtl8723de practitioner), the bluetooth driver for rtl8723de is in the kernel since 4.17, it always worked out of the box for me
(or did you want to suggest something else?)

[Factral]

I first blacklisted the controller with the command you suggested to me:

Code: Select all

  sudo modprobe -r rtw88_8723de
echo "blacklist rtw88_8723de" | sudo tee -a /etc/modprobe.d/blacklist-rtw88_8723de.conf

And then if I installed the other driver for the end, I don't know why, but immediately after installing it, the wifi connection started working.
Nothing happens if i leave the other controller blacklisted?

It will be fine (if you have two drivers installed, it's best to blacklist one of them), but I am simply curious why the kernel driver didn't work at first: because you hadn't yet done "rfkill unblock all", or because it's not such a good driver after all. In the last case, the Linux kernel team would like to know about that I guess.

edit: But since you must have followed the instructions for the smlinux driver already, because they are on the link you gave, it must have been "rfkill unblock all" that made the difference. So there's no need to test anything, I'm fairly sure the kernel driver would work for you too now, but of course you can leave things as they are.

What's the matter ?

@Factral:

If you like, you can edit post #1 and remove the "Solved" from subject line and start from the beginning.

I suppose I'm simply over curious on what exactly solved the issue. OK.
(I guess we differed in interpreting at which point the OP did "rfkill unblock all". But I'm pretty sure now it must have been that command that changed things, I edited my post to reflect this.)

I have the same problem on a Pavilion 15t laptop. I had MX Linux 19.1 installed and the Realtek driver was working from a git build. For some reason the OS glitched and I re-installed with 19.3 AHS which had the Realtek rtl8723de included. I followed the advice here, but when I use the inxi -n command I get a message that the driver is N/A

Device-1: Realtek RTL8723DE 802.11b/g/n PCIe Adapter driver: N/A

I've search around for answers, but cannot find a solution. Can anyone help?

does it work after you do this?

Code: Select all

sudo modprobe rtw88_8723de

have you installed another driver?
maybe you need to do

Code: Select all

rfkill unblock all
