sudo apt-get install --reinstall network-manager (can help, not sure ... ) – dschinn1001 Aug 24 '18 at 13:41
Please edit your question and include the output of lshw -C network. – Kulfy Aug 24 '18 at 14:05
Is it an external wifi adapter? If yes, can you give us the type of your adapter? – damadam Aug 24 '18 at 14:20
no, its inbuilt one @damadam – Bala Kumar Aug 24 '18 at 17:03
That's a known issue with Realtek 8723. Try this. It helped me to get the WiFi to work flawlessly on two of my friends' laptop. – Kulfy Aug 24 '18 at 18:21
