1. Official spelling: what the Russian Academy of Sciences says

According to Russian Spelling Dictionary of the Russian Academy of Sciences (2021 edition), term Wi-Fi In Russian, it has two acceptable spelling options:

• 📚 Wi-Fi — with a hyphen (recommended option for common texts)
• 📚 Wi-Fi — together (acceptable, but less preferable)

The original English spelling is Wi-Fi (with a capital letter and a hyphen) in Russian-language texts is not considered an error, but is used mainly in technical documentation, instructions And marketing materials equipment manufacturers.

It is interesting that in Gramote.ru (the largest reference portal on the Russian language) also confirm the priority of the version with a hyphen. However, in SEO texts fused spelling (Wi-Fi) is often encountered more frequently due to the popularity of this option in search queries.

⚠️ Attention: If you are writing an article for a tech blog or a guide on setting up a router, use Wi-Fi (in Latin) in the first mentions, and then - Wi-Fi (with a hyphen). This is in line with the standards. GOST R 7.0.12-2011 for technical texts.

2. How Wi-Fi router manufacturers write: Documentation analysis

We've looked at the official manuals of five popular brands (TP-Link, ASUS, Keenetic, MikroTik, Zyxel) and found out that:

• 🔧 TP-Link And ASUS use Wi-Fi (in Latin) in all instructions, even in Russian versions.
• 🔧 Keenetic alternates Wi-Fi And Wi-Fi (with a hyphen) depending on the context.
• 🔧 MikroTik And Zyxel prefer WiFi (without hyphen) in technical specifications.

Interesting fact: in mobile applications to manage routers (for example, Tether from TP-Link or ASUS Router) the term is always displayed as Wi-Fi — even in the Russian-language interface. This is due to the fact that the Latin alphabet is better perceived in UI/UX design and does not require additional adaptation for different languages.

Important for SEO: If you are optimizing an article for queries that mention a specific brand (for example, “settings Wi-Fi on Keenetic"), use the spelling preferred by the manufacturer. This will improve the text's relevance to search engines.

3. SEO aspect: which spelling is better for promotion

From a search engine optimization perspective, the choice between Wi-Fi, Wi-Fi And Wi-Fi depends on:

1. 🔍 Request frequency — what options do users search for most often?
2. 📊 Competitiveness - how difficult is it to get into the TOP for each option.
3. 🎯 Target audience - technical specialists or ordinary users.

According to data Wordstat.Yandex And Google Trends (at the time of analysis), the distribution of search queries looks like this:

• 📈 Wi-Fi — ~60% of requests (the most popular option among users).
• 📉 Wi-Fi — ~25% (most often searched in the context of official instructions).
• 📊 Wi-Fi — ~15% (mainly technical requests).

Practical conclusion: If you are writing an article for a general audience (for example, “How to connect Wi-Fi on the phone"), use continuous writing. If the target audience is IT specialists or business owners ("Setting up Wi-Fi for the office network"), give preference to the Latin alphabet.

Two letters "y" at the beginning and end ("wi-fi", not "wi-fi").
