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
Then navigate to
/etc/netplan/ using the
cd command the hit
$ cd /etc/netplan/
Use the command
ls to list the files and directories under the folder then you now have to edit the
$ 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
SSID-NAME and the
WIFI-PASSORD they have to be in quotes. The
: after SSID name is required.
Close and save the file using
yes by tipping the letter
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
