Turn the Wi-Fi on...

Ever walked into your house, turned on the light switch, and nothing happened—only to realize the main power was off? Booted up the Linux machine and Wi-Fi wasn’t working! Step 1: Check if the "Power Supply" (NetworkManager) is ON NetworkManager is like house's electrical panel—it manages which appliances (Wi-Fi, Ethernet, etc.) get power (internet). systemctl status NetworkManager Output: Active: inactive (dead) NetworkManager.service: Job NetworkManager.service/start failed with result 'dependency'. The main switch was off. Turn the Power Back On sudo systemctl restart NetworkManager Now it showed: Active: active (running) Lights are back on!

Ever walked into your house, turned on the light switch, and nothing happened—only to realize the main power was off?

Booted up the Linux machine and Wi-Fi wasn’t working!

NetworkManager is like house's electrical panel—it manages which appliances (Wi-Fi, Ethernet, etc.) get power (internet).

systemctl status NetworkManager

Output:

Active: inactive (dead)
NetworkManager.service: Job NetworkManager.service/start failed with result 'dependency'.

The main switch was off.

sudo systemctl restart NetworkManager

Now it showed:

Active: active (running)

Lights are back on!
