Raspberry Pi Asked by Gildas.Tambo on January 4, 2022
I have the Raspberry Pi 4 Model B and my choice of RAM was the 4GB. i don’t have internet via the gigabit ethernet at the moment, all i have is my smartphone to share internet via a hotspot (wifi).
i have installed Ubuntu Server 64-bit on the Raspberry 4 following the instructions on the ubuntu official webpage by flashing Ubuntu onto a 128GB samsung microSD card.
The installation went good, but now i want to connect the Raspberry to the internet via the command line to fetch some packages and install the desktop.
How can i setup the wifi via the command line on the Raspberry 4B 4GBRAM?
To be able to setup Wifi on Raspberry Pi 4 B+ 4GB on Ubuntu server 18 TLS, you first need to get the name of the Wifi card by showing physical components using the following command:
$ sudo lshw
in my case it was wlan0
Then navigate to /etc/netplan/
using the cd command
the hit Enter
$ cd /etc/netplan/
Use the command ls
to list the files and directories under the folder then you now have to edit the .yaml
file:
$ sudo nano 50-cloud-init.yaml
Finally, add the following lines to the 50-cloud-init file:
wifis:
wlan0:
optional: true
access-points:
"SSID-NAME":
password: "WIFI-PASSORD"
dhcp4: yes
NOTE: Make sure not to use tab for space, use the spacebar to create the blank.
Here is the final file code:
network:
ethernets:
eth0:
dhcp4: true
optional: true
version: 2
wifis:
wlan0:
optional: true
access-points:
"SSID-NAME":
password: "WIFI-PASSORD"
dhcp4: yes
Change the SSID-NAME
and the WIFI-PASSORD
they have to be in quotes. The :
after SSID name is required.
Close and save the file using ctrl
+x
and yes
by tipping the letter y
Finally, you need to do some debugs:
$ sudo netplan –debug try
$ sudo netplan –debug generate
$ sudo netplan –debug apply
then reboot the pi
$ sudo reboot
Install Ubuntu desktop with the following command:
$ sudo apt-get install ubuntu-desktop
