I have changed my macbook pro operating system to Ubuntu Linux last night. That night the wifi network was recognized but this morning it does not recognizing wifi network at all . Please help. here is what I got running Terminal:
ebmo@ebmo-MacBookPro:~$ nmcli

Use "nmcli device show" to get complete information about known devices and
"nmcli connection show" to get an overview on active connection profiles.
Consult nmcli(1) and nmcli-examples(5) manual pages for complete usage details.
