If you don't see your wireless network in the list of available networks on any device, your wireless router might not be set to broadcast its network ID (SSID). To turn on SSID broadcasting, refer to the info that came with your router.
Open the Command Prompt or PowerShell as Administrator. Type in netsh wlan add filter permission=block ssid="WIFI NAME" networktype=infrastructure replacing WIFI NAME with the name you want to delete. You should see The filter is added on the system successfully. If not, check your typing.
Troubleshooting StepsCheck that your wireless adapter is enabled and that Ubuntu recognizes it: see Device Recognition and Operation. Check if drivers are available for your wireless adapter; install them and check them: see Device Drivers. Check your connection to the Internet: see Wireless Connections.
What works for me is to add these lines to /etc/networks/interface.
auto wlan0
iface wlan0 inet dhcp
reboot, wait 1-2 min during booting process and it works flawlessly. Got answer from this link. I put this here for a shortcut.
Hope this helps!
