Over at Linux.com is a look at five network monitoring tools that will really help you determine not only what is utilizing your network but also its overall health. Bandwidthd is a tool for web hosts and LAN admins which tallies up incoming and outgoing bandwidth usage and can present it in a variety of time frames, from usage per day to usage per year. Nethogs tracks usage per process and Darkstat tracks total usage but comes with an embedded HTTP server which makes it fairly self contained. Speedometer is fairly self explanatory and to understand iperf you should read the write up here as it is a powerful tool for investigating the quality of your network.
"In this roundup of Linux network testing utilities we use Bandwidthd, Speedometer, Nethogs, Darkstat, and iperf to track bandwidth usage, speed, find network hogs, and test performance."

Linaro, a non-profit engineering group, announced a new collaborative organization called the Linux Networking Group at the Embedded Linux Conference in San Francisco this week. The new group will work on developing open source software to be used with ARM-based hardware in cloud, mobile, and networking industry sectors. Of course, being open source, the software for ARM SoCs will be used with Linux operating systems. One of the Linux Networking Group’s purposes is to develop a new “enhanced core Linux platform” for networking equipment, for example.
The new Linux Networking Group is currently comprised of the following organizations:
- Nokia Siemens Networks
- Texas Instruments
The new cooperative has announced four main goals for 2013:
- "Virtualization support with considerations for real-time performance, I/O optimization, robustness and heterogeneous operating environments on multi-core SoCs.
- Real-time operations and the Linux kernel optimizations for the control and data plane.
- Packet processing optimizations that maximize performance and minimize latency in data flows through the network.
- Dealing with legacy software and mixed-endian issues prevalent in the networking space."
Reportedly, Linaro will have an initial software release within the first half of this year. Further, the organization will follow up with monthly software updates to improve performance and add new features. More collaboration and the furthering of ARM-compatible open source software is always a good thing. It remains to be seen how useful the Linux Networking Group will be in pushing its ARM software goals, but here’s hoping it works out for the best.
The full press release can be found below.

Corsair sure does like to expand upon their product base. The company was founded in 1994 and produced only memory for quite a few years. The past five years have seen tremendous growth from the company in terms of SSDs, cases, power supplies, and high end cooling solutions. Corsair also dabbled in sound with a line of successful speakers (though these have not been updated in some time). Corsair is again making another move, but this time with an aime to deliver content around the entire house.
The front of the Roomplayer II is rather bland, but it should hide itself well in nearly any decor.
Simple Audio is a Scottish based company (if it isn't Scottish it's crap!) that designs and sells multimedia streaming solutions. The hardware is the Roomplayer 1 and Roomplayer II units which are high definition media players that are either amplified (forconnecting directly to speakers) or non-amplified to connect to current stereo and home theater systems. Audio is broadcast to these units from iOS enabled devices or PC and Mac computers via software provided by Simple Audio.
Corsair has acquired Simple Audio in a multi-million dollar transaction, but we do not have exact numbers due to Corsair being a privately owned company. From my understanding these products will still carry the Simple Audio name, but Corsair will be the parent company and will distribute the products throughout Asia and North America (two areas that Simple Audio currently does not support).
The back of the Roomplayer I is much more interesting as it has a 50 watt amplifier built-in so it can power speakers independently.
The Roomplayer solutions are apparently quite easy to hook up and their output is very clean (supports up to 24 bit sound natively). As the average consumer is becoming more and more comfortable with setting up a home network, this is an opportunity for both Corsair and Simple Audio to market these products in new regions where overall market penetration of networked home audio is still quite low.
Corsair is a very, very aggressive company when it comes to entering new markets. Their power supplies and cases are perfect examples of how they tend to do business. Corsair actually produces neither of those product lines, but instead relies on contract manufacturing to handle production. What Corsair certainly appears to do well is specify these components very well and handle end product quality control. There really are few overall complaints about Corsair and their products, and as a consumer I do hope that they have another good one on their hands.
The sales numbers will of course be key, and obviously Corsair feels comfortable enough with Simple Audio and their products to buy them up. We are not certain when we expect to see the Simple Audio products on store shelves, but Corsair typically does not screw around.
Now we only have to wonder, "Who is next on Corsair's radar?"
ASUS RT-N56U Wireless Router Review
On deck for review today is the ASUS RT-N56U “Black Diamond” Dual-band Gigabit Wireless-N Router. ASUS has a broad stable of networking equipment including wireless adapters, wireless routers, wired networking gear and even some power line networking gear. Released in late 2010, the RT-N56U is one of the lower cost offerings in ASUS’ Dual Band N series and can be found online for around $99.
ASUS RT-N56U Wireless-N Router Overview
The media review information supplied to us by ASUS claims the ASUS RT-N56U “Black Diamond” offers “Extreme performance in style.” The router’s “Aesthetic design” has a “Sexy and stylish approach with streamlined, meticulously designed and well-rounded appearance, just like diamonds sparkling and twinkling in the dark.” Now I don’t know about you, but if it’s dark, I’m not sure how you see diamond’s twinkling? But I digress; the RT-N56U is a great looking router, with the black cross hatched lattice surface we liked from previous ASUS routers.
Amped Wireless R20000G and UA2000 Introduction
Continuing with our networking adapter and router reviews, today we have a pair of devices on tap from a relative newcomer to the home and office networking field, Amped Wireless. Founded in 2007, they began selling Wi-Fi products in 2010. In those 2 years they’ve already pushed out a wide array of Routers, Range Extenders, Access Points, USB Adapters and Antennas/Boosters. While they don’t have the history of Cisco, Netgear or D-Link, it’s great to see new companies entering the fray as more competition can only benefit the consumer.
Today we’re looking at their flagship High Power Router, the Wireless-N 600mw Gigabit Dual Band R20000G as well as one of their leading USB adapters, the High Power Wireless-N Directional Dual Band UA2000. List price for the router and adapter is $169 and $99 respectively, but the router and adapter can be found online for about $10 less each at Newegg.

Intel's new Crystal Forest chipset includes an undisclosed embedded CPU, an 89XX-series chipset and their Data Plane Development Kit which is the SDK they've created for designing fast path network processing. This is not a competitor to AMD's Freedom Fabric which is designed for communication within a large series of processing nodes, instead you will see Crystal Forest powering high end routers and web appliances. Intel has designed this new chipset to increase the performance of cryptography and compression on network packets and claims it will increase speed as well as security, along with the benefits of support coming directly from Intel. The Inquirer reports a long list of vendors who have signed on, including Dell, Wind River Systems and Emerson Network Power.
"CHIPMAKER Intel has launched its Crystal Forest chipset for network infrastructure.
Intel might be best known for its X86 desktop, laptop and server chips but the firm does a pretty good trade in embedded chips and has announced that a number of large vendors have pledged their support for its new Crystal Forest chipset. The firm said its Crystal Forest chipset will enable networking equipment vendors to shift and control more data using its chips."

Some computer components get all the glory. Your normal lineup of FPS crushing GPU’s, Handbrake dominating CPU’s, and super-fast Memory end up with most of the headlines. Yet behind the scenes, there are some computer components we use that are pivotal in our use and enjoyment of computers and receive very little fanfare. Without networking we wouldn’t have file sharing, LAN parties or even the Internet itself. Without routers and network adapters, we wouldn’t have networking.
ASUS recently sent a whole slew of networking components our way and we’ve decided to take them for a spin and see if they’re worth your hard earned dollars. Our box of ASUS goodies included:
- ASUS RT-N66U Gigabit Router – Dual Band Wireless-N900
- ASUS PCE-N10 - Wireless N PCI-E Adapter Wireless-N
- ASUS PCE-N15 - Wireless N PCI-E Adapter Wireless-N
- ASUS USB-N53 - Dual Band Wireless N Adapter
- ASUS USB-N66 - Dual Band Wireless-N900 Adapter
Without further ado, let’s jump in and tackle each one.
ASUS RT-N66U Gigabit Router – Dual Band Wireless-N900
Routers are one of those components that most of us don’t really think about unless something goes horribly wrong. Most people will buy one they find on a big box store shelf (or even worse, just use their ISP’s router), pull it out of the box, plug a few cables into it and then forget about it in a closet for a few years.

Tagged: wifi, router, networking, netgear, 802.11ac
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.

Tagged: wireless, router, networking, ethernet bridge, buffalo, 802.11ac
Netgear and Buffalo have been working hard to build and get to market new wireless routers based on the 802.11ac (pending ratification) standard. PC Perspective recently ran a giveaway for the Netgear 802.11ac router, but it seems that Buffalo has managed to beat them to market with their new gear. In fact, Buffalo yesterday released two 802.11ac devices with the AirStation™ WZR-D1800H wireless router and WLI-H4-D1300 wireless Ethernet bridge. Both devices are powered by Broadcom’s 5G WiFi chips (what Broadcom refers to 802.11ac as–the fifth generation of consumer WiFi) and based around the IEEE standard that is set to become an official standard early next year.
The Buffalo 802.11ac Router (left: front, right: rear view)
The router and Ethernet bridge both support the upcoming 802.11ac standard as well as the current 802.11 b, g, and n standards so they are backwards compatible with all your devices. They also support all the normal functions of any other router or bridge device–the draft support for 802.11ac is what differentiates these products. The router stands vertically and has a router reset and USB eject buttons, one USB 2.0 port, four Gigabit Ethernet LAN ports, and one Gigabit Ethernet WAN port. Below the WAN port is a power button and DC in jack. The Buffalo Ethernet bridge allows users to connect Ethernet devices to a network over WiFi. It looks very similar to the router but does not have a WAN port or USB port on the back. It also does not act as a router, only a bridge to a larger network. The largest downside to the Ethernet bridge is pricing: (although out of stock now) Newegg has the bridge listed for the same price as the full fledged router. At that point, it does not have much value–users would be better off buying two routers and disabling the router features on one (and because the Broadcom chipset should enable custom firmwares, this should be possible soon).
The Buffalo 802.11ac Ethernet Bridge (left: front, right: rear view)
What makes these two devices interesting though is the support for the “5G WiFi” 802.11ac wireless technology. This is the first time that the Wireless connections have a (granted, theoretical) higher transfer speed than the wired connections, which is quite the feat. 802.11ac is essentially 802.11n but with several improvements and only operating on channels in the 5GHz spectrum. The pending standard also uses wider 80 Mhz or 160 MHz channels, 256 QAM modulation, and up to eight antennas (much like 802.11n’s MIMO technology) to deliver much faster wireless transfer rates than consumers have had available previously. The other big technology with the upcoming WiFi standard is beamforming. This allows wireless devices to communicate with their access point(s) to determine relative spatial position. That data is then used to adjust the transmitted signals such that it is sent in the direction of the access point at the optimum power levels. This approach is different to traditional WiFi devices that broadcast omni-directionally (think big circular waves coming out of your router) because the signals are more focused. By focusing the signals, users get better range and can avoid WiFi deadspots.
Hajime Nakai, Chief Executive Officer at Buffalo Technology stated that “along with Broadcom, we continue to demonstrate our commitment to innovation by providing a no-compromise, future proofed wireless infrastructure for consumers’ digital worlds.”
The Buffalo AirStation™ WZR-D1800H router and WLI-H4-D1300 Ethernet bridge are available for purchase now for around $179.99 USD. The Ethernet bridge is listed as out of stock on Newegg; however, the router is still available (and the better value).
