    Does this answer your question? [My wireless/WiFi connection does not work. What information is needed to diagnose the issue?](https://askubuntu.com/questions/425155/my-wireless-wifi-connection-does-not-work-what-information-is-needed-to-diagnos) – waltinator Aug 28 '23 at 21:41
  • @waltinator i executed the script,but the details on the github repo of the scipt have absolutely no clue on what to do after executing the script! – Soham Mane Aug 29 '23 at 15:48
  • Read the output of the script. The script is a compilation of all the networking checks that have benn found useful and could be automated. It should lead you towards a solution. – waltinator Aug 29 '23 at 16:32
