In youtube videos it shows under advanced settings but in my gateway there is no setting named ftp server
I tried the inspect element and did what you said, but the ftp option is not appearing for me.Just inspect the site and press CTRL+SHIFT+C and click on ADVANCED tab on the page (left hand side).
& then go to '<ul class="submenu">'
Then unwrap it.
select green text
right clich and select "Edit as HTML" and remove the '<!--' (beginning) & '-->' (end)
Now click on left side of textbox.
Now click ADVANCED and FTP server option is there

How were you able to access?. When i click on it, i get "401 unauthorised" error.
