Do all macbooks have wifi

What’s the earliest model of the MacBook to support Wi-Fi networks transmitting at 5GHz?

Is there documentation showing the earliest model of the MacBook (both Pro/Air preferred if possible) to have integrated hardware support for Wi-Fi networks using the 5GHz band?

Probably all of them. 802.11a was the first spec to use 5GHz & all MacBooks since 2006 have had that spec. If you mean 802.11n, then probably about 2009. en.wikipedia.org/wiki/IEEE_802.11

1 Answer 1

All MacBook models have shipped with support for 5GHz Wi-Fi networks since their first generation.

802.11a

802.11n (including draft-n)

• MacBook (Late 2006 thru Mid 2010)
• MacBook Air (2008 thru Mid 2012)
• MacBook Pro (Late 2006 thru Early 2013)

802.11ac

• MacBook (Early 2015 thru Mid 2017)
• MacBook Air (Mid 2013 thru 2020)
• MacBook Pro (Late 2013 thru 2020)

802.11ax

• MacBook Air (M1, 2020)
• MacBook Pro (13-inch, M1, 2020)
• MacBook Pro (14-inch, 2021)
• MacBook Pro (16-inch, 2021)

Roaming optimisation support for MacBook Air

Wi-Fi specifications for MacBook Air models

The following are the MacBook Air Wi-Fi specification details. The categories are:

• 802.11 compatibility and frequency band: 802.11ax ( Wi-Fi 6), 802.11ac ( Wi-Fi 5), 802.11n ( Wi-Fi 4), 802.11a, 802.11b/g, and 2.4GHz or 5GHz.
• Physical layer (PHY) data rate: The highest rate at which a client can transmit data over Wi-Fi .
• Channel bandwidth: The maximum channel bandwidth that is supported. Starting with 802.11n, channels can be combined to create a wider channel that allows for more data to be transmitted during a single transmission. With 802.11n for 5GHz band, two 20MHz channels can be combined to create a 40MHz channel. With 802.11ac for 5GHz band, four 20MHz channels can be combined to create an 80MHz channel.
• MCS index: The Modulation and Coding Scheme (MCS) index defines the maximum transmission rate at which 802.11ac/n devices can communicate. 802.11ac uses Very High Throughput (VHT) and 802.11n uses High Throughput (HT) frames.
• Spatial streams/SISO/MIMO: Each radio can send a specific number of independent data streams, called spatial streams, at the same time, which can increase overall throughput. Single input single output (SISO) uses a single radio and antenna, and multiple input multiple output (MIMO) uses multiple radios and antennas.

Apple MacBooks Now Support WiFi 6. Here’s What You Need To Know

We’ve all spent most of the last decade relying on something called WiFi 5, but that’s all in the past now. Don’t worry about that. It’s time for the future. And the future is WiFi 6 . which just so happens to be supported by all the latest Mac computers.

But what does that actually mean for you, the consumer? In short, it means home WiFi is about to theoretically get more reliable, but only so long as you own WiFi 6-ready equipment.

Before you take the plunge on a new laptop and WiFi 6 router, here’s what you need to know.

How much faster is WiFi 6?

First, let’s pump the brakes a little bit on any lofty expectations you may have for WiFi 6 based on those opening paragraphs. Settle down. Take deep breaths. As usual, these things are somewhat complicated.

The WiFi standard you likely use right now has a maximum transmission speed of around 3 Gigabits per second (or Gbps for short), per our friends at PCMag. That said, home internet in the United States sorta blows and you can’t really get a signal that fast anywhere. Not even close. Anyway, WiFi 6 expands that maximum threshold to nearly 10Gbps, roughly tripling what a WiFi 6 router can do when pushed to its limits.

Even if no router on Earth is ever pushed to that limit, the main benefit here is less about making your laptop faster and more about giving your WiFi connection extra juice to feed your multitude of hungry connected devices all at once. Even still, PCMag’s testing showed signal strength increases of anywhere from about 30 to 60 percent on compatible devices in the same room as a WiFi 6 router.

In short, WiFi 6 can give you a noticeable (if not especially breathtaking) speed boost if you’re close to the router and, more importantly, take pressure off your router when multiple people are trying to stream HD movies, play video games, make Zoom calls, or wirelessly stream VR at the same time. The nice thing is we’re still in the early days of WiFi 6 adoption, so it should only get better from here.

What other devices support WiFi 6?

One argument for getting a WiFi 6 router now is that you might already own some devices that can take advantage of it. Again, it’s still mostly tech for early adopters, but maybe that describes some of you!

Here are just a handful of devices that currently support WiFi 6:

• iPhone 11 and 12, as well as the newest iPhone SE
• Galaxy S20, Galaxy Note 20, and Galaxy Fold 1 and 2
• OnePlus 8 phones, such as the Pro and 8T
• Samsung 8K TVs like the Q900
• ASUS Chromebook Flip C436
• PlayStation 5

As you can imagine, that list is sure to grow over time. If you already own (or plan on owning) any of those products, it might be smart to get a WiFi 6 router. Speaking of which.

Good WiFi 6 routers you can buy

There are a number of solid WiFi 6 routers out there from big, trusted brands like Netgear and Linksys, which is nice. What’s less nice is that they’re naturally a little more pricey than you might expect. That’s technology for you. Luckily, the wizards over at PCMag diligently test routers and have a handy roundup of some good ones for different purposes.

The ASUS RT-AX88U comes with eight Ethernet ports, which will only make things easier on your WiFi connection if you use them properly. Aside from that, PCMag recommended it due to its quality performance and ease of use. It can be had for $300 on Amazon at the time of writing. If Ethernet ports really matter to you, the TP-Link AX6000 has your back.

This $400 Netgear Nighthawk router may be more pricey, but it also promises superior performance if lots of people are using WiFi on it at once. In general, it seems like you’re going to have to pay at least $250 or so for a decent WiFi 6 router.

We understand if that’s too much, but the good news is you don’t have to do it right now. The WiFi you’ve been using this whole time isn’t going away. Just understand that you’ll probably have to buy a new router if you want to get the most out of your new MacBook.
