I know there is an option to do it manually by changing the files in /etc/NetworkManager But is there an option where I can modify the wifi settings for my connections without having to do that every time?

  • What are you modifying in /etc/NetworkManager? Have you tried `nm-connection-editor`? – heynnema Jun 01 '20 at 17:39
  • @heynnema The procedure I followed is mentioned [here](https://askubuntu.com/questions/1231022/how-can-i-get-the-band-2-4-5-ghz-selection-back-in-wifi-settings-ubuntu-20) I did not try `nm-connection-editor` before. Thank you it has the options I need. For some reason these options are not included in the network settings which was not the case in previous versions of ubuntu. – Mohamed Jun 01 '20 at 18:57

In terminal, use nm-connection-editor.
