The network manager is missing in Debian 11 LXDE. How to connect to a wireless network?

#1 Post by tshark »

There is no GUI to connect to a wireless network. I don't have wired connection at the moment, so I have to use wi-fi

You need firmware-iwlwifi firmware for wifi.

As for without network manager, you can use wpa_cli to connect to wifi.

Install wicd (a GTK graphical network manager application)
# Become root
$ su

# Install Wicd
$ apt-get install wicd

# Launch Wicd
$ wicd-gtk
Once you've installed and launched Wicd network manager click 'Switch On Wi-Fi' then click 'Refresh' and you should see a list of available networks in your area.

If you can't see any networks offered by wicd then your wifi chip probably requires firmware to work, install the required firmware first as others pointed in previous comments, you may need to enable the non-free repos to do that.

It seems Wicd was indeed removed from Debian 11 bullseye as pointed by @4D696B65, I suggest you use nmtui instead, another semi-graphical tool

Code: Select all

# Become root
$ su

# Install nmtui (the package itself is called network-manager)
$ apt-get install network-manager

# Launch it by typing in terminal
$ nmtui
Image

Select 'Activate a connection' to get a list of available wireless networks in your area.

I did not know this :)

Used to be a big fan but wicd was always slow to connect for me. connman is making me happy these days.

connman works
Description: Intel Connection Manager daemon
The Linux Connection Manager project provides a daemon for managing
Internet connections within embedded devices running the Linux
operating system. The Connection Manager is designed to be slim and to
use as few resources as possible. It is fully modular system that
can be extended through plug-ins. The plug-in approach allows for
easy adaption and modification for various use cases.
.
ConnMan provies IPv4 and IPv6 connectivity via:
* ethernet
* WiFi, using wpasupplicant
* Cellular, using oFono
* Bluetooth, using bluez
.
ConnMan implements DNS resolving and caching, DHCP clients for both IPv4 and
IPv6, link-local IPv4 address handling and tethering (IP connection sharing)
to clients via USB, ethernet, WiFi, cellular and Bluetooth.
.
This package contains the connman daemon and its plugins.
NO need for network-manager and its heavy overhead.

No need for connman either, but it is good.
Just use systemd, no package required.

Absolutely. Here are instructions.

Use CLI to get on line and then download whatever you need.

BTW, a computer that never moves, such as a desktop tower, only needs one connection. In this case configuring /etc/network/interfaces is all that is needed. I'm typing this on a computer that does not have a network GUI and the connection is flawless.

Not even /etc/network/interfaces is needed, when I upgraded my desktop tower to Bullsey, it made /etc/systemd/network/20-wired.network

Code: Select all

[Network]

Functionally the same thing; both are systemd configuration.

I am having the same problem. Fresh install of Debian 11 LXDE, followed the advice in this thread and I cannot get the wifi to work. Why doesn't Debian 11 LXDE come with wifi enabled by default? Not everyone is a Linux geek. :(

Code: Select all

$ lspci |grep Network
07:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev ff)
$ lsusb
bash: lsusb: command not found

Code: Select all

$ sudo apt install firmware-iwlwifi
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package firmware-iwlwifi

Code: Select all

$ /usr/sbin/connmanctl
bash: /usr/sbin/connmanctl: No such file or directory
$ connmanctl> enable wifi
Error 'wifi': Unknown command
and so on and so forth. The advice given here doesn't work. Please help me try something else. Thank you.

BTW, I installed nm-tray, but Enable wifi is greyed out.

OK, upon reboot, nm-tray shows Enable Wifi with a check mark next to it. When I click on Edit connections nmtui-edit pops up, I put in my network name and password, click add, ok, but nothing happens when I try to switch from wired to wifi in nm-tray. What am I missing?

Installing firmware-iwlwifi is not going to help as that is a Realtek chip. And you need to enable non-free repository to install firmware.
The one you need is firmware-realtek.
