\"\"<\/p>\n

Sometimes after disconnected from a VPN network in Ubuntu 20.04, wireless does no longer work and even shows ‘No Adapter Found’ in the settings. If you have the same problem, this tutorial may help.<\/p>\n

Without restarting<\/b> your computer, you can try following steps to make the wireless work again.<\/p>\n

1.) Restart Wifi network via system menu.<\/b><\/p>\n

Try turn off wireless network from system tray menu, and turn it on again.<\/p>\n

\"\"<\/p>\n

This works in the case when I disconnected from PPTP VPN server.<\/p>\n

2.) Restart Wifi network via nmcli.<\/b><\/p>\n

The previous step may not work sometimes. If so, try running commands in terminal (Ctrl+Alt+T<\/b>) to restart networking:<\/p>\n

nmcli networking off \r\n\r\nnmcli networking on<\/pre>\n
And this works in the case when I disconnected from a ExpressVPN server.<\/p>\n
\"\"<\/p>\n
3.) Restart Wireless interface via ifconfig<\/b><\/p>\n
You may also run following 2 commands to restart the wireless network:<\/p>\n
sudo ifconfig wlo1 down\r\n\r\nsudo ifconfig wlo1 up<\/pre>\n
NOTE you need to replace wlo1<\/b> to your wifi network name (usually wlan0<\/b>). Check it via ifconfig<\/code> command.<\/p>\n
4.) If none of the previous steps works, you may try to reload the wireless kernel module.<\/b><\/p>\n
Open terminal (Ctrl+Alt+T) from system application menu and run command to check your wireless driver:<\/p>\n
sudo lshw -C network 2>&1 | grep wireless | grep driver<\/pre>\n
As the picture shows, it’s rtw_pci<\/b> in my case.<\/p>\n
\"\"<\/p>\n
Then run command to reload the kernel module:<\/p>\n
sudo modprobe -r MODULE_NAME && sudo modprobe MODULE_NAME<\/pre>\n
In my case the command is (rtwpci<\/code> did work though it should be rtw_pci<\/code>):<\/p>\n
sudo modprobe -r rtwpci && sudo modprobe rtwpci<\/pre>\n
