Belkin N1 Wireless Router

Posted on September 26th, 2006 in Hardware, Router | No Comments

With its intuitive status icons, up-to-date security options, and stellar support, the Belkin N1 Wireless Router is on the path to 802.11n wireless networking stardom, but, like other Draft N devices, its performance fails to impress.

Like the Linksys WRT300N and Netgear WNR834B routers, the N1 uses the Draft N spec of the upcoming 802.11n Wi-Fi standard, which could be ratified early in 2007. Belkin’s router offers a mixed 802.11b/g/n mode instead of single-mode operation, however. This discrepancy makes direct performance comparisons impossible, although the N1 did trounce the Linksys and Netgear Draft N routers in mixed-mode and long-range (in mixed mode) throughput tests. Nonetheless, the N1’s overall performance, which was nowhere near the 300Mbps maximum throughput the 802.11n standard promises.

The N1 impressed in other ways, however. Belkin has given its Pre-N router design a makeover, replacing the slate-gray plastic with a slick silver-and-black exterior. Better still, Belkin replaced the standard LED lights with a top-mounted network-status display, which gives you a better handle on your network via icons representing each network element.

The router has all the standard wireless security options, including Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA) encryption, stateful packet inspection (SPI) and network address translation (NAT) firewalls, and Media Access Control (MAC) address filtering.

Posted on September 24th, 2006 in Hardware | No Comments

The Iomega’s StorCenter Wireless Network Storage 1TB is a 1-terabyte network-attached drive array that will have you sharing everything from printers to high-definition video pronto. The StorCenter includes a Gigabit Ethernet port, two USB 2.0 ports, and two screw-on antennas for wireless setup. A fan keeps things cool, though it particularly noisy.

Although some problems with Iomega’s Discovery Tool come with the CD, the software is supposed to scan and identify the StorCenter drives on your network. It also lets you arrange the StorCenter’s four 7,200rpm drives in a RAID 0 (striping), RAID 5 (striping with parity), or RAID 0+1 (mirroring and striping) array. Note that the drives are not user-replaceable.

WiMAX in Sri Lanka

Posted on September 22nd, 2006 in News, WiMax | 3 Comments

Sri Lanka telecom will partner with chipmaker Intel to launch WiMAX in Sri Lanka. WiMAX is a broadband wireless network that is based on the IEEE 802.16 standard which can give greater coverage than Wi-Fi technology. SLT is planning to deploy the WiMAX network across the island within a year once it gets regulatory approval. The WiMAX network will be launched in phases and the first phase will cover metropolitan areas including Colombo, Galle and Kandy and is estimated to cost about US $1 million.

Securing the Wireless Network

Posted on September 20th, 2006 in Security, Tips & Tricks | 1 Comment

Since WiFi offers the benefits of easy setup without wires and cables, it has proved to be very popular among net savvy users. The increase in the number of available access points is a testament to WiFi’s new found popularity. Easy connectivity, however, comes at a price – wireless networks have poor security compared to their wired counterparts. When you network two computers using a wireless connection, the data is sent via radio waves on a certain channel. Thus anyone with a receiver (a wireless card will do) can analyze the data being sent. This is called sniffing.

If you are running an open network, a cracker with a laptop can listen in and analyze everything that you are doing online – the websites you visit, the emails you send, even the user name and passwords you exchange with servers. After connecting to your network, he may be able to scan and connect to other machines as well. Sharing your WiFi by keeping your access point open is regarded as nice, but there are instances where you want to secure your data. Here’s how to protect your WiFi network:

SSID Cloaking
Wireless networks identify themselves by a SSID, which can be something like ‘mywireless’. Computers with a wireless card whose SSID is set to ‘mywireless’ can connect to each other. Access points send out periodic beacons which are meant to indicate their presence. These beacons also usually broadcast the respective SSID. Thus, anyone with a sniffer can find out that there is a network with a SSID and connect to that.

A basic form of security is to disable the broadcast of SSID. When this is done, the access point doesn’t identify itself when sending out its beacon packets. An intruder who doesn’t know the SSID won’t be able to connect to the network. The weaknesses of this method is that the network’s SSID is sent via other data packets as well. If you listen long enough to the communications between two networks, the SSID can be easily found, making connecting as easy as before.

Sprint goes WiMax; Wall Street goes flat

Posted on September 18th, 2006 in News, WiMax | No Comments

There’s never a good time to tell investors that you plan to spend about $3 billion on a new technology platform, but it’s really bad timing after a sisappointing quarter. That’s the take-away from Sprint Nextel’s Aug. 8 announcement that it will build a WiMax network with help from Intel, Samsung and Motorola. While Sprint Nextel’s announcement was big news in technology circles, those following the money had mixed reviews.

Among the do’s and don’ts cited by observers:

  • Do undertake a big effort with major players riding shotgun. Wall Street analysts said Intel, Motorola and Samsung are high-quality partners that can lend credibility to Sprint’s attempts to build a new network, dubbed 4G, for those following the industry. Why does Sprint need big names behind it? “Sprint is currently being criticized for failure to establish the quality of its network in consumers’ minds and poor handset selection,” said Jeffrey Halpern, an analyst at New York-based Sanford Bernstein, in a research report.
  • Do tell industry watchers about how WiMax can leapfrog the competition. That’s no small issue given doubts that Sprint Nextel can hang tough with the likes of Verizon Wireless and Cingular Wireless.

You’re probably mastered the art of setting up a Wi-Fi wireless network in your home. But what if you want your network to extend for 5, 10, 20 miles or more? That may sound fanciful, but it’s not so tough to achieve long-distance wireless connectivity. You just need to add a few tools to the mix and get to work on your mash-up.

To help you, we tracked down a chapter from Mike Outmesguine’s ExtremeTech book, Wi-Fi Toys: 15 Cool Wireless Projects for Home, Office, and Entertainment, from Wiley Publishing You can find it online at PCMag. It details how to select your access point sites, choose your antennas, and more. Creating a long-distance link simply means marrying many of the essentials of wireless with a dose of physics to overcome the obstacles of a far-reaching connection.

Or perhaps you’re interested in the subtle art of wardriving using a car equipped with a computer, a wireless card, and software to identify the presence of a Wi-Fi signal, even if you’re out on a deserted highway. What an excellent idea! It’s surprising how ubiquitous Wi-Fi signals have become. You’ll find everything you need to get started as a budding wardriver at PC Mag.

Finally, several blogs contain complete instructions for upgrading the capabilities of Linksys routers. Take a look at www.lifehacker.com for some interesting examples. You don’t have to settle for bush league Wi-Fi.
