OS X is holding back the 2013 MacBook Air’s 802.11ac Wi-Fi speeds

Apple’s 2013 MacBook Air and new Airport Extreme Base Station are the company’s first 802.11ac products, and there are some bugs that need to be worked out. Apple Apple’s 2013 MacBook Air doesn’t look like much of an upgrade from the outside, but the story is different on the inside. We’ve spent the better part of a week using the new Air and measuring just how Intel’s new Haswell processors , the PCI Express-based SSD , and the 802.11ac Wi-Fi adapter change the laptop compared to last year’s model. The new Wi-Fi chip was the change that I was the most eager to get my hands on. I’m always looking to boost my network speeds, but I’ve been waiting for hardware based on the new 802.11ac standard to become more widely available before upgrading everything on my network. Reviewing both the new Air and Apple’s new 802.11ac-capable Airport Express Base Station simultaneously would give me a chance to see just how close the lauded “Gigabit Wi-Fi” would come to fulfilling its promises. I was unpleasantly surprised by the results. Both the 2012 and 2013 MacBook Airs use four antennas to transmit data—two to send data and two to receive it. Each set of antennas can theoretically send and receive 150Mbps (or 18.75MBps) using 5GHz 802.11n for a total of 300Mbps (37.5MBps). Under 802.11ac, the size of each stream is increased to 433Mbps, making for a maximum theoretical link speed of 866Mbps (108.25MBps) in the 2013 MacBook Air. Actual network transfer speeds rarely (if ever) come within spitting distance of these theoretical maximums, but we would at least expect the actual 802.11ac transfer speeds to increase by a similar percentage compared to 802.11n.

ASUS launches dual-band router with combined 1900Mbit/s speeds

Some of ASUS’s big Computex 2013 launches today involved the latest 802.11ac WiFi flavor, and since you’ll need to feed them with a router packing the same tech, ASUS has also announced one of those: the RT-AC68U. The company claims it’s the first dual-band 802.11ac router with AC1900 data rates up to 1900 Mbit/s, thanks to AiRadar beamforming, which helps bring a stronger connection and 150 percent better range, too (if accurate). You’ll also be able to share files between ASUS routers with USB-attached drives thanks to a router-to-router sync mode, negating the need for a switched-on PC or other device. There’s no word on pricing or availability, but the previous RT-AC66U flagship ran about $200 or so — so we’d be surprised if it came in under that figure.

OS X 10.8.4 beta suggests 802.11ac is coming soon to a Mac near you

Amid the sea of text, a revealing phrase: 802.11ac. 9to5Mac Before rolling them out to the public through Software Update, Apple regularly releases beta versions of its minor OS X updates to registered developers and other selected testers. These patches are normally routine—a security patch here, a new driver there—but they occasionally reveal tidbits about where Apple is taking OS X and, by extension, its Mac lineup. A new build of OS X 10.8.4 was released to beta testers today, and 9to5Mac cracked it open in short order. Hidden in the operating system’s “WiFi-frameworks” folder is a brand-new reference to 802.11ac Wi-Fi , a new standard that promises bandwidth of up to 1.3Gbps. The fastest Wi-Fi chips in today’s Macs support 802.11n at speeds of either 450Mbps (for devices with three antennae like the iMac or MacBook Pro) or 270Mbps (for devices like the MacBook Air with only two antennae), making the new standard quite the potential upgrade. As with previous Wi-Fi upgrades, the new 802.11ac adapters and routers will also be backward-compatible with 802.11n, g, b, and a-based devices. Routers and adapters that support 802.11ac first began to appear on the market last year, and have slowly proliferated as the months have gone on. We saw quite a few 802.11ac routers at this year’s CES , and 802.11ac chips from the likes of Broadcom should begin to show up in many consumer devices this year. Even some smartphones (the HTC One in particular) are beginning to ship with the new standard, so it wouldn’t be a surprise if Apple made the jump in this year’s Macs.
