Hi,=A0=0A=
A few months ago I updated the system from Debian 10 to 11. Always in Debia=
n I had to do the Wifi driver installation manually, the last one that did =
works I downloaded from=A0https://github.com/lwfinger/rtw88.=A0=0A=
=0A=
But, a few days ago, I had to do a clean install. So I downloaded Debian 11=
.5 and again I did the manual installation of the driver.=0A=
In this case, when I reboot the laptop the operating system loading is stuc=
k in "Started Display Manager".=0A=
But, if I login in rescue mode, and of course uninstall the driver, the I c=
an logon normally to the system but without WiFi!=0A=
=0A=
I was investigating a lot, but it seems there is a problem with that kernel=
 version and my driver (there is not a new version of the driver for my wif=
i card rtl8723de) because if I do the installation again, but before reboot=
ing I try what the README of driver says:=0A=
=0A=
sudo modprobe -r rtw_8723de =A0 =A0 =A0 =A0 #This unloads the module=0A=
sudo modprobe -r rtw_core=0A=
=0A=
Due to some pecularities in=A0the modprobe utility, two steps are required.=
=0A=
=0A=
sudo modprobe rtw_8723de =A0 =A0 =A0 =A0 =A0 =A0#This loads the module=0A=
=0A=
Only a single modprobe call is required to load.=0A=
=0A=
I can use Wifi (in fact I am writing right now this email with WiFi working=
 smoothly!), but again in the next reboot the initializing is stuck. No err=
ors I could read in logs.=0A=
=0A=
So, I think that my workaround: "poweroff - poweron, system loading stuck -=
 force poweroff - poweron in rescue mode - uninstall driver - reboot - logo=
n on system - install driver again and use WiFi like a normal person"=0A=
is not enough efficiently.=0A=
=0A=
Kindly ask to you (it =A0indicates from=A0instructions README of driver) if=
 there is a solution for this issue?=0A=
=0A=
BTW, I tried to install Ubuntu 22.04 with Kernel 5.16.xx and the WiFi works=
 fine, but I'm a Debian user since Debian 5 and I don't think to leave it a=
nd I have no money to buy another Laptop for the moment!=0A=
=0A=
If you need something from my side to do a deeper investigation, please ask=
 me.=0A=
