Cannot connect to network

OK, after ‘sudo’, how do I post the results if there is no Internet connection?

No matter, when I type it, and hit enter, the pureos@pureos:~$ prompt reappears, and I checked the command line spelling. Assuming Tilix is the program to use to enter the sudo command.

UPDATE: After opening every available access except MoBo, I found a manual for the Tosh A660–0QE that says “LAN, Realtek wireless 801.11 bgn,…” (Ewww!)

There is no access to the WiFi like other ltops. No idea where this is inside ltop.
