The free French guide is authored by a French writer and covers Debian Jessie. The Debian Buster version by the same creator is available in English. Both resources cover fundamental commands, interface setup, and network service configurations. In summary, they explain how to operate the command line. https://debian-handbook.info/ bye
Sure, I'm happy to help. Thank you for your patience and support. Once I have the solution, I'll share it here.
I provided the answer. Locate the settings file that activates the default dormant or power-saving mode. Using nano as your editor is simpler than vim for this task. Tools like find, xargs, and grep can help with searching through files.
NetworkManager alternative to disable Wi-Fi power saving is a manual configuration change. If you see the setting wifi.powersave set to 3, adjust it to 2. Use nano to edit the file, save with Ctrl+O, exit with Ctrl+X, then set permissions and reboot. After rebooting, verify the status via ip link show. This method permanently disables the power-saving mode as per RFC2863 and the Wi-Fi interface "wlp1s0".
Upgrading isn't necessary whenever you modify the system. Rebuilding grub and reinstalling initramfs each change is redundant. If power management problems occur—common with Realtek WiFi chips—Linux Hardware indicates it uses the "rtl8821ae" module. You can turn off power management by issuing the command to disable it and then restarting.
