If you’re having trouble with the Wi-Fi on your new mid-2013 MacBook Air, a fix may be on the way.

Per AppleInsider, in a likely response to reports of 802.11ac Wi-Fi issues with its latest MacBook Air refresh, Apple late Friday began sending out invitations to select users, offering inclusion in the AppleSeed Program to test an upcoming Wi-Fi centric software update for the notebook.

Sources who received the email said that Apple will provide selected customers with a pre-release version of the “MacBook Air WiFi Update 1.0″ to install and use on their new machines, asking that they give feedback on any bugs found during the testing process.

While not explicitly stated in the AppleSeed invite, it is thought that the update relates to recent Wi-Fi connectivity issues some customers have experienced with Apple’s implementation of the fairly new 802.11ac wireless standard.

The recently-released 11- and 13-inch MacBook Airs are the first Macs to implement the fast wireless protocol which, when combined with the new AirPort Extreme or AirPort Time Capsule, can reach theoretical speeds of up to 1300Mbps.

Although the technology has promise, a growing number of owners have complained of throughput limitations related to 11ac, with some reports speculating the wireless stack in OS X is at least partially to blame.

A thread on Apple’s Support Communities webpage appears to confirm the AppleSeed invitations, but offers little information on the software. Those who have already agreed to Apple’s terms said the company has yet to activate the invitation codes or send out the software.

In December 2012, Apple released a similar Wi-Fi compatibility update for Mac two months following the debut of the MacBook Pro with Retina display. At the time, owners of the then-new machine complained of problems recognizing 802.11n networks in the 5GHz band.

If you’ve received the notice or have experienced any Wi-Fi issues with a mid-2013 MacBook Air, please let us know in the comments.

Study finds mid-2013 MacBook Air’s 802.11ac Wi-Fi speeds throttled by bug in OS X

Even in the event that the Wi-Fi connectivity issues on the mid-2013 MacBook Air notebooks are hardware-based, the underlying operating system software is apparently throttling potential data speeds on the new networking protocol.

Per AnandTech and CNET, a series of tests by AnandTech confirms that much of the Wi-Fi speed throttling is software-based. The new MacBook Air was announced by Apple at the recent Worldwide Developers Conference, and in addition to extended battery life, the new systems include support for 802.11ac Wi-Fi networking, which supports up to three times faster data rates in comparison with 802.11n.

In testing, AnandTech noticed that the link speeds of the systems are very high, at an average of about 533Mbps, but when transferring files over standard networking protocols, the speed drops to about 169Mbps at its maximum. This is over three times less than the expected speeds.

In investigating the issue, AnandTech discovered that an apparent bug in OS X limits the TCP window size (the maximum data that can be sent at a time) to a maximum of 64KB, which is far less than the 256KB needed to meet the speed capabilities of the 802.11ac connection.

As a result of this finding, AnandTech shows that in its current state, while the 2013 MacBook Air will still give fast file transfers, these will be limited to about 21MBps, instead of the more than 50MBps expected. Luckily, this limitation being in software means the fix should be easy, and it may be only a matter of a quick update for these systems to realize their full potential.

Stay tuned for additional details as they become available.

Apple looking into mid-2013 MacBook Air Wi-Fi issues, “capturing” units for study

This might be why your friends, the ones who wait a month or two after a brand new product hits the market, could be right…

Per 9to5Mac, over the past few days, a notable amount of users have complained about Wi-Fi issues plaguing the new 11-inch and 13-inch MacBook Air models released during the week of WWDC. Besides less-battery-intensive chipsets, the marquee feature of the new MacBook Air revolves around faster Wi-Fi connectivity thanks to new 802.11ac cards. As with any new product, bugs are plausible. It’s also been noted that new reports claim that the MacBook Air WiFi issues are due to networking issues in Apple’s OS X software.

The following facts are currently in place:

In the United States, Apple Geniuses and Advisors should capture MacBook Air (13-inch, Mid 2013) and MacBook Air (11-inch, Mid 2013) computers with any Wi-Fi issues.

According to a source at Apple, the company is working to independently identify what exactly is causing the new Wi-Fi-related problems. According to the source, AppleCare and Apple Store Genius Bar employees have been instructed to “capture” affected MacBook Air units. These units will then be sent back to Apple for further testing so a solution could hopefully be achieved. While Apple is asking AppleCare and Genius Bar staff to “capture” units facing problems, that does not mean Apple is confirming the new MacBook Air is flawed. This points to Apple pushing to determine why at least some units are seeing Wi-Fi problems.

There have also been reports of at least a couple of customers facing MacBook Air WiFi issues who have successfully swapped out their notebooks for new ones. One of these people has said that AppleCare provided them with a complementary USB-to-Ethernet adapter so the new MacBook Air could connect to the internet without Wi-Fi. Apple also informed these people that their original laptops have been “captured”.

If you’ve picked up Apple’s latest MacBook Air notebook and have any feedback to provide about its 802.11ac Wi-Fi performance, please let us know in the comments.

Growing number of users cite Wi-Fi connectivity issues with 802.11ac-equipped MacBook Air notebooks

To be fair, this is what they invented firmware updates for.

Per Gizmodo, some early adopters of Apple’s latest MacBook Air models have found their new thin-and-light notebook will unexpectedly and repeatedly drop its wireless connection.

A growing discussion thread on the Apple Support Communities website details the connectivity problems being experienced by numerous users. The problems appear to apply to both the 11- and 13-inch varieties of the recently updated notebook lineup.

In addition, an anonymous source from an Apple retail store in London said that their store has had complaints about wireless connectivity for the new MacBook Airs that are “well above average.”

In the thread, users say they’re experiencing the problems across a range of routers, including Apple’s own AirPort accessories. Users say they can initially connect to a Wi-Fi network, but that connection will drop after a short period of use.

At the moment, there doesn’t appear to be an available solution that addresses the problems seen by all users, though some have had success with various routers or even different placement of the MacBook Air.

The updated MacBook Air lineup launched last week at Apple’s annual Worldwide Developers Conference. In addition to faster 802.11ac connectivity, the notebooks also feature Intel’s latest Haswell processors, helping to enable battery life as great as 12 hours.

The new MacBook Airs are also priced US$100 less than their predecessors, with the new low-end US$999 11-inch model packing 128 gigabytes of flash storage.

This was a weird thing that popped up, but it’s hard to argue with the Emergency Alert System.

Per The Mac Observer, wireless carrier AT&T began pushing an update to iPhone users over the weekend that adds support for Wireless Emergency Alerts. The WEA system sends text messages to smartphone owners alerting them to physical threats like earthquakes and tornados, man-made disasters, AMBER Alerts, and Presidential alerts.


carrierupdate

The update is being pushed to the iPhone 4, 4S, and 5, and doesn’t require any action on the user’s part since it’s delivered over the air. Once installed, alerts will appear as special text messages and are delivered based on your location. For example, if an AMBER alert is issued for a missing child and you’re in the same city, you’ll see the notification.

The update is free, and since it’s a carrier-supplied update, it won’t appear in iOS 6′s built-in Software Update feature.

The Sprint network grows.

And that’s generally not a bad thing.

Per iMore, wireless carrier Sprint has announced a major expansion of its LTE rollout, adding coverage to 22 more cities today, bringing the number of markets with access to Sprint’s high-speed network up to 110. The new cities are as follows according to the company’s press release:
- Baton Rouge, La.

- Centralia, Wash.

- Clarksville, Tenn.

- Corsicana, Texas

- Dalton, Ga.

- Dunn, N.C.

- Fond du Lac, Wis.

- Gainesville, Fla.

- Henderson, N.C.

- Kingsport, Tenn.

- Lansing/East Lansing, Mich.

- Longview, Wash.

- Miami, Fl.

- Napa, Calif.

- New Orleans, La.

- Palatka, Fla.

- Raleigh, N.C.

- Sebring, Fla.

- St. Cloud, Minn.

- St. Joseph/Benton Harbor, Mich.

- Tampa, Fla.

- Warsaw, Ind.

An additional 13 cities, including Ann Arbor, Laredo, and Corpus Christi, are scheduled to receive coverage “in the coming months”. Sprint stated that their LTE network would be available to 200 million people by the end of 2013, a number mostly theoretical, as many of them would undoubtedly be customers of Sprints competition. The expansion shows that Sprint is serious about their LTE rollout, no matter who may buy the company.

If you’re in these new expansion areas and have Sprint as your wireless carrier, please let us know about the performance in the comments.

European Union to remove roaming fees starting July 2014

Next summer will be a good time to wander through Europe.

Per The Telegraph, for anyone traveling to Europe next year, as of next July 2014, you’ll pay the same rate for calls and data when travelling within Europe as you do at home.

Consumers will next year be able to use their mobile phones across the European Union for the same price as at home, it is planned, after officials voted to fast-track major reforms of telecoms regulation.

Roaming fees for voice calls, texts and internet access will effectively be completely scrapped under the proposals, which are part of a broader effort to create a single European telecoms market.

Roaming fees can often be extortionate, with call fees of over £1 (US$1.56) per minute, and data charges which can easily rack up hundreds of pounds for quite ordinary usage. The banning of roaming fees applies only for European customers: customers from the USA and other countries will still pay roaming charges when visiting Europe.

The EU estimates that carriers will initially see a 2 percent drop in revenue, but expect it to benefit them in the longer term by encouraging greater use of mobiles while traveling and by making it possible for networks to attract customers across borders.

iFixit completes teardown of 802.11ac AirPort Extreme, finds space for drive bracket among changes

The new 802.11ac AirPort Extreme is out and, continuing a long and fine tradition, iFixit tore the sucker apart without a moment’s hesitation.

Per CNET and the official iFixit teardown page, the new tower-like router arrives with a bracket that can easily house a hard drive, but appears to be just large enough to perfectly accept a 3.5-inch hard drive and hold it at a diagonal.


80211acairportextreme

Unfortunately there are no connections (or space for them) in the system, so while there may be similar Time Capsule devices based on this design, iFixIt claims it will likely be very difficult (if not impossible) to modify an AirPort Extreme to be a Time Capsule.

On the sides of the drive bracket are two circuit boards that hold the power supply and logic board, containing 4GB of synchronous DRAM, 32MB of serial flash memory, and a Broadcom router controller. These components are encased in heat sinks and thermal venting, with a small fan to provide active cooling.


axparts

The innards are connected by six contacts to a flat, square antenna that is perched at the top of the tower and is the size of the end of the unit. Oddly, this deviates from Apple’s explanation at the WWDC keynote that the elongated design was to house the antennas and beam data from the sides. Instead, it’s evident that the beaming happens from the top of the unit.

Regarding repairability, iFixIt rates the new AirPort Extreme fairly well with a score of 8 out of 10. The reasoning for this is its modular design, lack of proprietary fasteners, and lack of glued components, making it easy to disassemble. Of course getting to the innards required a bit of prying, and some fasteners are small and delicate, so iFixIt settled on an overall rating of 8.

If you’ve picked up the newest AirPort Extreme router and have any feedback to offer about it, please let us know in the comments.
