Правильно писать Wi-Fi, ибо у них так записано в бренд-гайде.
При желании могу ссылку кинуть. На сайте wi-fi. org есть Wi-Fi_Alliance_Brand_Styleguide_201307. pdf, и там на 19-й странице все написано.
Wifi как пишется правильно
This is a case similar to facial tissues being generically referred to as «Kleenex». There are many examples of a trademark becoming a generic term, in which case the original capitalization or other unique stylization become lost or varied. Other common examples include Aspirin, Cellophane, Dry ice, Escolator, Kerosene, Lanolin, Laundromat, Linoleum, TelePrompTer, Thermos, Trampoline, and Videotape. — Source
The official term is «Wi-Fi». However, when English users treat a trademark generically, the «rules» for what is proper become the relative prevalence of the unofficial usage.
Wi-Fi is a trademark of the Wi-Fi Alliance. The name is sometimes written as WiFi, Wifi, or wifi, but these are not approved by the Wi-Fi Alliance. – Source

This is a very topical issue for our time, since wireless networks have simply taken over the entire country in the last 10 years. But as a rule, ordinary users often mispronounce the word, and write it incorrectly. How do you spell Wi-Fi in English?
NOTE! I tried to cover this question as fully as possible, but if after reading the article you still have questions – write them in the comments and I'll be happy to answer them.
Written by
Also, if you are really picky, the first few letters are capitalized, but the pair of letters "i" is written with a small letter. So writing it as "WI-FI" is fundamentally wrong. The fact that the letters take their root from the phrase "Wireless Fidelity," which can be literally translated as "Wireless Fidelity.
These four letters were invented to abbreviate it. Since it is two words, not 4, that are used, the capital letters are only used for the initial characters. Generally speaking, the wireless standard was invented by the Wi-Fi Alliance. It is also incorrect to write this name in Russian:
After all, it is not our word and should be written strictly in English. Another mistake is to write it as "WiFi", that is, together. It is necessary to put a hyphen in the center. If you write the name in the documentation, it is also a gross mistake to put spaces before and after the hyphen. There should be no spaces at all. It is also wrong to write all the letters with a lower case.
I suggest that you read more about Wi-Fi itself.

Pronunciations
Here everything is easy to pronounce. I'll write it in Russian to make it clear. It's pronounced like "Wai Fai". First you say "Wai", then pause for half a second and then "Fai". Now about the accent. The accent should be on the second letter a – "Vai Fai". Not on the first one, but on the second one. Well, as the "wifi" – you should not pronounce it, it sounds very rural and is often used as a pun.
What else can you call "wi-fi"? It can also be called "Wireless Network" or "Access Point." That is, a local place where a local network is distributed by radio waves.

A brief introduction to wireless networking
It turns out that 90% of users get confused between Wi-Fi and the Internet. Let me tell you a secret – these are absolutely different things. Wi-Fi is not the Internet. It is just a technology that allows two or more devices to communicate with each other via radio waves according to IEEE 802.11. Let me explain using an example.
Ivan has a router (or a router, which is the same thing) at home. A cable from the provider is connected to it from the entrance, through which the Internet flows. Next, to distribute to phones, tablets or laptops Internet – you need to configure the router WiFi network. Once configured, it can connect any device that has a special transmitter.
So, if the provider will disconnect Ivan from the Internet for non-payment, the wireless network will continue to exist, but without the Internet. So my dear friends and readers – do not confuse the concept of "Internet" and "Wi-Fi" – they are completely different things. They can exist without each other.
Be sure to read – what is a router and what it is used for.
Another interesting fact is that radio waves with a frequency of 2.4 GHz are used as transmission. The same frequency is used by mobile operators, microwave ovens, radios and many similar devices. But more recently, a new 5 GHz data transmission standard has been introduced. On this wave, the data is transmitted much faster and the speed is higher.
But as I wrote earlier, it is the speed of the local wireless network, not the Internet. By the way, this is often used by marketers from companies that produce routers. Since the average consumer confuses the Internet and wi-fi, he often catches the eye to the inscription that this router can support speeds: 300, 450 Mbit per second, or even a few Gigabits.
But in reality, Internet speeds higher than the one provided by the provider – will not. Therefore, this speed is only possible within the local network – that is, in your home between your devices.
Pronunciations
Here everything is easy to pronounce. I'll write it in Russian to make it clear. It's pronounced "Wai Fi. First we say "Vai", then a pause of half a second and then "Fai". Now about the accent. The accent should be on the second letter a – "Vai Fai". Not on the first one, but on the second one. Well, as "wifi" is not worth pronouncing, it sounds rustic and is more often used for puns.
What else can you call "wi-fi"? It can also be called "Wireless Network" or "Access Point". That is, a local place where a local network is distributed by radio waves.
