The Buffalo AirStation WZR-D1800H is the first 802.11ac (aka 5G Wi-Fi) router on the market, and Buffalo's WLI-H4-D1300 wireless media bridge is the first 802.11ac client. Since those are currently the only two 5G Wi-Fi devices, it was impossible to get a complete picture of the 802.11ac standard itself by testing them.

However, I was able to quite easily pair them together and experience the 802.11ac connection. Unfortunately, while the connection was very fast, it wasn't close to what the 802.11ac standard has to offer.… Read more

Now that you can actually buy the first wireless networking products that use 802.11ac, Buffalo's router and media bridge, it's time you learned about the this new wireless standard. While the "ac" designation definitely does not mean "air conditioning," I can say for sure that 802.11ac is cool.

And by cool, I mean fast. That's the biggest difference about 802.11ac compared with previous wireless standards. But first let's see how similar it is.

802.11ac supplements 802.11n

802.11ac (aka 5G Wi-Fi) is the next step after 802.… Read more

SEATTLE--A new company that plans to track millions of retail shoppers through a unique ID emitted by their smartphones says it wants to be privacy-friendly.

Will Smith, co-founder and chief executive of Euclid Elements, showed up at the PII privacy conference here today to say that identifying repeat visitors by these unique IDs -- the so-called MAC addresses broadcast when Wi-Fi is turned on -- shouldn't be an issue.

"We put a sensor in the store," Smith said. "It passively detects smartphones that come near the store."

Euclid, which is based in Palo Alto, Calif. … Read more

NEW ORLEANS--Wireless carriers are looking to Wi-Fi to help them offload traffic from their cellular networks. And a new standard will make it even easier for consumers to use the unlicensed airwaves. But would you pay extra for that easy access?

The Wi-Fi Alliance, a trade association promoting the use of Wi-Fi, says a recent survey indicates that nearly three-quarters of respondents said they would.

The Wi-Fi Alliance is promoting the new standard, which will basically allow people to access a carrier's Wi-Fi without ever typing a passcode or even selecting a Wi-Fi hot spot. The technology will automatically … Read more

Yesterday Apple released the OS X 10.7.4 update, which addressed a number of problems and security issues in OS X, including the logging of some users' passwords in plain text and the long-standing log-out option for reopening windows always being enabled. Along with this update, however, came a security update to Bluetooth that has caused some people's Bluetooth configurations to not work properly.

The Bluetooth service in OS X 10.7 through 10.7.3 had a bug that meant a local user could potentially hack the Bluetooth daemon process and execute arbitrary code with system privileges, … Read more

While Netgear and D-Link introduced their approaches to app-supporting and cloud-enabled networking products at CES 2012, Cisco, which didn't have anything to announce at CES, turns out to be the first to materialize the new concepts.

Cisco today unveiled a line of Linksys Smart Wi-Fi routers that promises to change the face, and the body, of home networking.

The Linksys EA4500, EA3500, and EA2700 -- the "A" designation being short for "app-enabled" -- look like models in the earlier E Series but have more-powerful hardware and support Cisco Connect Cloud, the next generation of Cisco … Read more

The problem is a simple one to encounter. You should have Wi-Fi but for some reason the reception just isn't there. That's exactly what struck OS X Daily, just after it got a new iPad from Apple.

And the guys from OS X Daily are not alone. Threads on support sites including the Apple Support Communities report the same issue, where Wi-Fi is not able to connect during setup. If your experience is similar to either case, there are quite a few trick to try before demanding a refund or writing Tim Cook.

The solution, according to OS … Read more

The advertising agency Bartle Bogle Hegarty's BHH Labs launched a campaign at the film, music and interactive festival South by Southwest (SXSW) in Austin, Texas, that is raising ire among critics.

In what appears to be a case of poor judgment, BBH Labs kicked off a campaign called "Homeless Hotspots." Yep. It is exactly what it sounds like--walking, talking homeless people who provide access to a 4G network in exchange for a donation (BBH Labs suggests $2 per 15 minutes). … Read more

The Asus Transformer Prime is currently the highest-quality Android tablet on the market. It rivals and sometimes surpasses the the iPad 2 in games performance, has a fantastically bright screen, memory expansion, various CPU performance modes, HDMI, and a thin, sleek, and sexy design.

All that said (and I bet you saw this coming), it's not perfect. Since its release, the Prime has been saddled with reports of performance issues, bugs, and stuff just outright not working.

How severe are these issues, and maybe more importantly, just how widespread are they? As a new or potentially new Prime owner, just what are the chances they'll crop up for you?… Read more
