To check if a wireless card is detected on Ubuntu, follow these steps:
- Open a terminal by pressing Ctrl+Alt+T or searching for Terminal in the launcher.
- Type in the following command and press enter:
lspci | grep Network
This will display information about any network adapters attached to your device. If there is a wireless card installed, it should appear in the results.
- Alternatively, you can also check the output of the ifconfig command by typing:
Look for any wireless interfaces such as wlan0 or wlp2s0 listed in the output. If there is a wireless card, it should appear here as well.
If you have a USB wireless adapter, you can also run
lsusb command to check if it's detected.
