Wifi not working after install - RTL8723DE

I've just installed 20 (Cinnamon), and I've had the nasty surprise of finding that wifi wasn't even seen by the system (when it worked perfectly fine with the live version).

I've followed the instructions given here viewtopic.php?f=53&t=322651&p=1833055&h ... e#p1833055 by sleeper12, and 'lo and behold, the OS now sees the card, but tells me no wireless network are available. I've tried to change the antenna parameter from 1 to 4 with the following command :

Code: Select all

sudo modprobe -r rtl8723de && sleep 10 && modprobe rtl8723de ant_sel=1
And, unfortunately still no go.

Any suggestions ?

Here are the system informations

1 to 4? :shock:

There's only 1 and 2 to try. There are no more flavours, as the default laptop WiFi chipset has only two antenna sockets.

Secure boot is disabled and wireless (and bluetooth) are not blocked, either through hardware or software.

Code: Select all

rfkill list 
0: phy1: Wireless LAN
	Soft blocked: no
	Hard blocked: no
2: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no

Code: Select all

mokutil --sb-state 
SecureBoot disabled

That all looks good. Try:

Code: Select all

 sudo modprobe rtl8723de 
Or

Code: Select all

 sudo ifconfig wlp2s0 
If that doesn't help, see if you can turn wifi on in Bios or reset Bios to default.

Oops. I didn't pay attention (I need new glasses) and used both.

Well, I just updated the kernel and, of course, it stopped functioning. I guess I'll try the whole process again...

You may have lost the driver with a kernel update. Does this show a driver in use?

Code: Select all

 lspci -nnk | grep -iA3 net

Well, one modprobe rtw88 and a reboot later, it works. I'll see if it keeps.

I'm not sure how you got rtw88, but if it works..ok.
