I am currently using ubuntu 16.04 and the wifi adapter I have is rtl8723be. I have installed the appropriate drivers and the wifi worked decently until now, I just created a wifi hotspot recently, but after that I cannot find the list of wifi networks available , even when I am right below the router. The only way I am able to connect is via connect to hidden network, although by that I get proper speed, but the wifi icon above shows no network,(i.e. the wifi signal icon is fully grey rather than fully white/ partially white) any solutions?

  • Do you see anything here sudo iwlist scan? – Py-ser Jul 22 '18 at 16:07
  • yes , there is a lot of info given including some 'Interface doesnt support scanning' – Sugato Jul 22 '18 at 17:13
  • on the output above, try to see if you see your wi-fi (it should be at the beginning and your wi-fi name should be at ESSID). Post the output of your wifi. Then try `sudo systemctl restart network-manager, this should reset your network, can you connect after the reset? – Py-ser Jul 22 '18 at 17:26

  • this was small part of the large output, the output gave information about all the wifi networks available but after I ran the command sudo systemctl restart network-manager, my wifi got connected with the hotspot network I created in my laptop(I dont know how) – Sugato Jul 22 '18 at 18:44

Try to restart your Network manager with:

sudo systemctl restart network-manager

This usually does the job.

  • it restarted the wifi only to connect it to the hotspot network configured in my laptop – Sugato Jul 23 '18 at 14:51
