With the term Wi-Fi The situation is ambiguous: it hasn't yet been formally established in academic dictionaries, but it's already widely used in technical literature and the media. Let's examine which variants are considered preferable in different sources.

Russian language rules: hyphen, together or separately?

• 🔍 Search engines (eg. Yandex or Google) understand all options equally well, so errors do not affect the results.
