Every so often, Ubuntu Wi-Fi connection gets hung-up (or frozen). It usually happens after switching locations and Wi-Fi networks.
When I click the empy Wi-Fi icon in the upper right corner it either show the last Wi-Fi network or no network at all. Either way, it doesn’t connect.
I found three solutions:
- Restart the computer. This refreshes the list of Wi-Fi Networks. But it’s frustrating when you have a few projects open.
- Click on the only available network in the Wi-Fi drop down. This sometimes causes the software to refresh. But, it doesn’t always work.
- Restart Network Manager & the Wi-Fi connection with the Terminal application. This refreshes the list of Wi-Fi networks. It also helps avoid the headache of closing all programs and restarting my computer.
Here is the Terminal command for restarting Network Manager:
sudo service network-manager restart
