The solution depends on the TeX engine that's in use. If you use pdfLaTeX, load the package fontenc with the option T1. If you use either XeLaTeX or LuaLaTeX, nothing special needs be done in order for \ng to work properly, though loading the fontspec package is probably a good idea anyway.

A full MWE (minimum working example)

\documentclass{article}

\usepackage{ifluatex,ifxetex}
\ifluatex
  \usepackage{fontspec} % optional
\else\ifxetex
  \usepackage{fontspec} % optional
\else % assume that pdftex engine is in use
  \usepackage[T1]{fontenc}
  \usepackage[utf8]{inputenc} % optional for "\ng"
\fi\fi

\begin{document}
\ng
\end{document}
