The Killer 1535 Wi-Fi adapter was the first 2x2 MU-MIMO compatible adapter on the market when it launched earlier this year, and is only found in a few products right now. We had a chance to test it out with the recently reviewed MSI G72 Dominator Pro G-Sync laptop, using the new Linksys EA8500 MU-MIMO router. How did it perform, and just what is MU-MIMO? Read on to find out!
Killer networks certainly haven’t skimped on the hardware with their new wireless adapter, as the Wireless-AC 1535 features two external 5 GHz signal amplifiers and is 802.11ac Wave 2 compliant with its support for MU-MIMO and Transmit Beamforming. And while the adapter itself certainly sounds impressive the real star here – besides the MU-MIMO support – is the Killer software. With these two technologies Killer has a unique product on the market, and if it works as advertised it would create an attractive alternative to the typical Wi-Fi solution.
MU-MIMO: What is it?
With an increasing number of devices using Wi-Fi in the average connected home the strain on a wireless network can often be felt. Just as one download can bring your internet connection to a crawl, one computer can hog nearly all available bandwidth from your router. MU-MIMO offers a solution to the network limitations of a typical multi-user home, and in fact the MU in MU-MIMO stands for Multi-User. The technology is part of the Wave 2 spec for 802.11ac, and it works differently than standard MIMO (multiple input, multiple output) technology. What’s the difference?
With standard MIMO (also known as Single-User MIMO) compatible devices take advantage of multiple data streams that are propagated to provide faster data than would otherwise be available for a single device. Multiple antennas on both base station and the client device are used to create the multiple transmit/receive streams needed for the added bandwidth. The multiple antennas used in MIMO systems create multiple channels, allowing for those separate data streams, and the number of streams is equal to the number of antennas (1x1 supports one stream, 2x2 supports two streams, etc.).

Tagged: wifi, FCC
Because blocking a person's mobile hotspot so you can charge them to use your Wi-Fi is a completely jerk thing to do. The FCC has just released a warning to any individuals, groups, or businesses considering these measures that blocking Wi-Fi is illegal. This follows the decision in October to fine Marriott, the hotel chain, $600,000 for blocking personal networks in a Tennessee location.
Now who's blowing the Raspberry?
Marriott, despite paying the fine, asked the commission to consider writing an official rule on this practice. They just did. It is illegal. The blocks of spectrum belonging to wireless internet are unlicensed, and thus no particular entity is apparently allowed to claim ownership over it, even in their geographic property.
It seems like a good decision to me, one that I cannot think of any immediate side-effects for, but this is one of those cases that a problem could be hiding in plain sight. What do you think? Am I missing something? Or is this a win for everyone (except those trying to block competing services)?

Carting a large sized USB drive around is handy but Kingston has gone one step further with the MobileLite Wireless device which acts as a WiFi router for an attached USB drive or SD card. It sports a 1800mAh 3.7v battery which should allow for up to 5 hours of usage and up to 3 devices can connect at any time making it a nice WAP you can carry around with you. By not including any storage media Kingston kept the price down and with SD support you can store quite a bit in the device as long as you purchased a large SD card. The transfer rates that HiTech Legion were seeing were not incredible but would suffice for streaming video and certainly data.
"Kingston MobileLite Wireless is a flexible Wi-Fi storage device that is lightweight and portable. The MobileLite Wireless acts as a USB hub and a card reader when plugged in to a laptop or a desktop computer. When unplugged, the MobileLite Wireless can then be used as a wireless file server, allowing up to three simultaneous wireless device connections to access the data stored on both the USB port or the SD card reader slot when populated."

The originally reported vulnerability was based around a specially designed QR code causing Google Glass to connect to a WiFi network not of the owners choosing which would allow monitoring of data flowing to and from the effected Google Glass device. While this issue was indeed patched there you still need to be aware that connecting to random WiFi can be a big security risk thanks to an unpatched spoofing bug effecting essentially all browsers. As The Register reminds everyone, unless you are at least encrypting your traffic or using a VPN your data transmission should not be considered secure.

A security expert recently reminded people that the Preferred Networks List Bug which was identified in 2004 has only ever been addressed by Microsoft. All other mobile OSes, from Apple to BlackBerry can accidentally expose their PNL to an eavesdropper who can then spoof it. If you like setting up autoconnect on your devices you might want to double check the name of your active connections occasionally; if you are connected to your home WiFi while you are out you might have a problem. Catch more at The Register.
"Security expert Raul Siles has warned that years after it was first identified, the Preferred Networks List (PNL) Wi-Fi bug remains unaddressed on many an iPhone, Android phone, and Windows or BlackBerry handset."

Following up on the announcement by Buffalo Technology, Netgear has released their own 802.11ac wireless router, the R6300. (PC Perspective recently ran a giveaway for the R6300 which you can read about here). In addition to the flagship 802.11ac router, Netgear announced a slimmed down version–the R6200–and the A6200 WiFi USB dongle.
The Netgear R6300 is their highest end wireless router supporting the 802.11ac WiFi standard. It supports 802.11ac speeds up to 1300 Mbps (450 Mbps over wireless n) and is backwards compatible with the 802.11 a/b/g/n standards. It also has two USB 2.0 ports that can be used to share hard drive and printers across the network. Further, the “5G WiFI” router is powered by a Broadcom chipset, which should open the door to third part firmware(s).
In addition to the above router, Netgear has announced the R6200 wireless router. It is compatible with the upcoming 802.11ac standard, but at reduced speeds. It features approximately 900 Mbps transfer rates over the “ac” standard and up to 300 Mbps over the 802.11n standard. The router is backwards compatible with all the older consumer standards (a/b/g/n), and it features a single USB 2.0 port to share a printer or hard drive to computers on the LAN.
Last up in the announcement is the Netgear A6200. This device is a USB WiFi dongle that supports the 802.11ac standard as well as existing a/b/g/n networks. It claims to deliver enough speed for HD streaming of videos, though Netgear has not stated if it will be able to take advantage of the full 1300 Mbps theoretical maximum connection. The WiFi adapter features a swiveling antenna and a docking station for use with desktop systems.
The other neat feature that the new routers support is the Netgear Genie application, which allows users to monitor and control the network using an application on their computer or smartphone (iOS and Android). They also feature Netgear MyMedia, printer sharing, guest network access, a DLNA server, parental controls, and automatic WiFi security.
The Netgear R6300 router is available for purchase now with an MSRP of $199.99. The R6200 router and A6200 WiFi dongle will be available for purchase in Q3 2012 with suggested retail prices of $179.99 and $69.99 respectively.
