The NETGEAR WNR2000 Wireless-N Router, featuring the new 802.11n, or Wireless-N, standard, offers range and performance that is superior to previous generation 802.11g routers. When used with RangeMax Wireless-N adapters and Wireless-N devices, this router will significantly boost the speed and performance of your wireless network. And because it’s backwards compatible with Wireless-G standards, you can continue to use your existing Wireless-G devices.

Features

• Wireless-N router offers significant speed and performance improvements over Wireless-G
• Simple and secure way to share your high-speed Internet connection
• Works with older Wireless-G devices and new Wireless-N devices
• Push ‘N’ Connect features simplifies set-up process; no need to remember complicated security keys or passwords
• Measures 7 x 5.1 x 1.4 inches (HxWxD); one-year warranty

The router has an elegant and clean design, relying on internal antennas that offer maximum range without detracting from its streamlined look. An on/off switch lets you turn off the router when it’s not in use. Energy Star compliant, the WNR2000 is stingy in its power use, and with packaging that’s made of 80-percent recycled materials, it’s as green as it gets.

What people talks?

This router looks very nice. The lines are clean (there is no external antenna). The plastic is shiny. The lights on the front are stylish. The only thing I didn’t like was that the manual said that the unit MUST be used in the vertical position, due to concerns about operating temperature (and probably the internal antenna, too). This is fine and all, but I liked the ability of the Linksys and other routers I’ve owned to be wall-mounted or positioned horizontally. The router is set up thoughtfully, and I like the on/off switch; I’ve never seen one on a router before, and I don’t intend to use it, but it’s nice to be able to turn off a piece of electronic equipment for a change! The packaging was spartan, sensible, and minimal, which I liked., michael

PROS:

1. Easy set up and configuration right out of the box
2. Sleek, simple and elegant design
3. Respectable price to obtain Wireless-N performance
4. No protruding and unsightly plastic antenna sticking out that looks like an old TV box
5. Automatic Firmware upgrade checking
6. Energy Star Partner / Netgear Green product

CONS:

1. 2 internal antennas (versus 8 internal antennas for the RangeMax line)
2. NO GIGABIT wired ethernet connection. For a little bit more, you can get the WNR3500 with greater wireless coverage and faster wired speed (if your computer supports it, of course)
3. Hit and miss quality and longevity per user feedback here and elsewhere
4. Hit and miss customer support including attitude and price for after-sales warranty service
5. Should already be half-price due to the existence of a better Netgear RangeMax product line
6. A wireless printer support via USB port would be nice

The Netgear WNR 2000 is a good router for basic WiFi connections. If you are a Mac owner and don’t feel comfortable setting things up without some handholding, you might want to consider an Apple Airport instead. Also, power users who do a lot of video streaming, connect multiple computers to WiFi, require gigabit Ethernet ports, or want an extremely strong signal with maximum range may want to consider Netgear’s RangeMax routers., korova

See larger image Linux Networking Cookbook (Paperback) By (author) Carla Schroder List Price: $44.99 USD New From: $19.55 In Stock Used from: $6.50 In Stock

This soup-to-nuts collection of recipes covers everything you need to know to perform your job as a Linux network administrator, whether you’re new to the job or have years of experience. With Linux Networking Cookbook, you’ll dive straight into the gnarly hands-on work of building and maintaining a computer network.

Running a network doesn’t mean you have all the answers. Networking is a complex subject with reams of reference material that’s difficult to keep straight, much less remember. If you want a book that lays out the steps for specific tasks, that clearly explains the commands and configurations, and does not tax your patience with endless ramblings and meanderings into theory and obscure RFCs, this is the book for you.

You will find recipes for:

• Building a gateway, firewall, and wireless access point on a Linux network
• Building a VoIP server with Asterisk
• Secure remote administration with SSH
• Building secure VPNs with OpenVPN, and a Linux PPTP VPN server
• Single sign-on with Samba for mixed Linux/Windows LANs
• Centralized network directory with OpenLDAP
• Network monitoring with Nagios or MRTG
• Getting acquainted with IPv6
• Setting up hands-free networks installations of new systems
• Linux system administration via serial console

And a lot more. Each recipe includes a clear, hands-on solution with tested code, plus a discussion on why it works. When you need to solve a network problem without delay, and don’t have the time or patience to comb through reference books or the Web for answers, Linux Networking Cookbook gives you exactly what you need.

What people talks?

“Linux networking cookbook is a book for both a seasoned and new Linux network administrator. It includes valuable time saving recipes, tools and related resources. The book is written in clear and concise style with tons of examples and working code.

Sure you can dig out all info presented here with the help of man pages, web, forums and chat rooms, but not in one handy guide. (remember time is an important factor in Enterprise computing).

Overall it is a great book that touches all important Linux networking aspects. This book is highly recommended to all RHCEs/ Geeks / MCESs / UNIX admin and small business owner who manges their own Linux boxes.”, nixcraft

“This cookbook gets quickly down to business with an amazing breadth of useful networking information. I’ve found it to be an excellent guide for hands on learning of networking with Linux

The book only asks that you have a basic understanding of working from the command line. Where applicable the instructions for various solutions are given for Fedora and Debian.

The most valuable parts for me thus far are how to access machines remotely and this applies to working on your linux box remotely and working with windows machines remotely from a linux machine. As networks become increasingly mixed with unix/linux and windows – this book is going to be more and more relevant and useful in that area.”, peck

This is not a book about networking theory (for that, see Andrew S. Tanenbaum’s Computer Networks (4th Edition)). Rather, as the word “Cookbook” suggests, this book offers step-by-step instructions (“recipes”) for installing, configuring, and starting up the relevant software packages, and then testing and debugging to make sure everything is running correctly. Where appropriate, Schroder offers separate recipes for deb- and rpm-based Linux distributions., John

Please check whether the power-source choice jumpers are in correct positions. For 20..54 V DC powering to the power plug or power header, switch the JP4 and JP5 jumpers into 1-2 position. For 48V DC Power over Ethernet powering, switch the JP4 and JP5 jumpers into 2-3 position.

Also check that the JP6 jumper is in 1-2 position and that J18 and J11 power outputs are open.

When I connect power to the board, it does nothing, but all its LEDs stay on

Please check that JP1 (Reset) jumper is open.

I am experiencing uncommon behavior (instability) of RouterBOARD

First, upgrade the BIOS and check if the RouterBOARD is still unstable.

If it is, try to disable pci back-off parameter in BIOS setup.

Common practice, how to choose the pci back-off parameter value:

• Keep enabled if you are using Atheros PCMCIA cards
• Enable on newer RouterBOARD 200 boards (with 266MHz CPU clock) with Atheros MiniPCI cards in RouterBOARD 14 (4-port MiniPCI-PCI) adapter
• Disable on older RouterBOARD 200 boards (with 233MHz CPU clock) with Atheros MiniPCI cards in RouterBOARD 14 (4-port MiniPCI-PCI) adapter
• Disable it if you are using newer RouterBOARD 200 boards (with 266MHz CPU clock) with external PCI Ethernet cards.

All of these practices has been defined experimentally, so they may or may not apply to your particular case.

What to do if my CMOS settings are resetting each time I power-off my board?

First, check that the CMOS reset jumper JP3 is in the 1-2 position. If it is, then try to replace the CMOS battery. The correct battery type is CR1620 Lithium Coin.
