The Good: The Netgear N750 Wireless Dual Band Gigabit Router (WNDR4000) supports the new 450Mbps standard on the 5GHz band, and offers true dual-band, decent wireless performance, and other advanced networking features, such as guest networking, network storage, and Live Parental Controls, for a comparatively affordable price. The Bad: The Netgear WNDR4000's 2.4GHz wireless throughput degrades a great deal as range increases. The performance of the network storage feature could also use some improvement. The Bottom Line: The Netgear WNDR4000 makes a very good wireless router for home use, especially with Wi-Fi clients that support the 5GHz band. First announced at CES 2011, the N750 Wireless Dual Band Gigabit Router (WNDR4000) is a major upgrade to the Netgear WNDR3700 RangeMax, as it supports a speed of 450Mbps (as opposed to 300Mbps) on the 5GHz band. This makes it the direct competitor of the recently reviewed Cisco Linksys E4200, and it's a decent contender, all things considered. Unfortunately, except for the close-range throughput on the 2.4GHz band and the more comprehensive guest networking feature, the WNDR4000 trails behind the E42000 in terms of performance, features, and ease of use.\n\nWith that said, the Netgear WNDR4000 is still a very good router. At a street price of around $150, about $20 cheaper than the Linksys E4200, it makes a worthwhile investment for both home and small office environments, especially ones with Wi-Fi clients supporting the 5GHz band. Other, similar options are the Cisco Linksys E3200 and the Asus RT-N56U.\n \nDesign and setup\nThe Netgear WNDR4000 router comes in a squared-off shape with a sleek casing that attracts fingerprints. The router can work in a horizontal or vertical position (when coupled with an included detachable stand) and is wall-mountable. \n\nOn the back the router has one WAN port (to connect to an Internet source, such as a broadband modem) and four LAN ports (for wired clients). All of these ports are Gigabit Ethernet, offering a top speed of 1,000Mbps. Also on the back you'll find an on\/off button and a USB port to host an external hard drive for the router's network storage feature.\n\nOn the front, the router boasts an array of color-changing LED lights indicating the status of the Internet connection, the wireless network, and the ports on the back. Near these LEDs is the Wi-Fi Protected Setup (WPS) button that helps quickly hook Wi-Fi clients into the wireless network.\n\nIt's very easy to set up the router with the included Netgear Genie software application, which is somewhat like Cisco Connect on the Linksys E4200. While Netgear Genie isn't as easy to use as Cisco Connect, as the setup process takes longer and involves more steps, we don't think anybody would have trouble getting the WNDR4000 up and running. We were able to do that within about 10 minutes, including the time needed to take the router out of the package.\n\nFeatures\nThe WNDR4000 is the first true dual-band router from Netgear that offers the higher 450Mbps speed that's available only in the 5GHz band. This is the new three-stream standard (also known as 3x3) that's getting more and more popular for high-end wireless routers. As a true dual-band router, the WNDR4000 is capable of simultaneously broadcasting Wireless-N signals in both the 2.4GHz and 5GHz bands. On top of that, the router is also able to broadcast two more guest wireless networks, one for each band. Guest networking, another increasingly popular feature, creates separate wireless networks that enable guests to access the Internet without having access to local resources such as files or printers. \n\nWe liked the WNDR4000's guest networking feature as it supports two additional networks and an unlimited number of connected clients. The Linksys E4200 provides guest networking only in the 2.4GHz band, and supports a maximum of 10 concurrent clients.\n\nThe Netgear Genie setup software takes you through the process of creating the two main wireless networks. In order to set up the guest networks, you'll need to log in to the router's Web interface by pointing a connected computer's browser to the router's default IP of 192.168.1.1. Here you'll have access to the router's other advanced features.\n\nOne of these features is support for a USB external hard drive so the router can host networked storage, similar to a NAS server. The WNDR4000 has some basic features found in Netgear's dedicated NAS servers such as the ReadyNAS Ultra4. We tried the network storage option with a few external hard drives and were pleased with how it was designed. \n\nFirst off, the router supports hard drives formatted in both NTFS and FAT32 file systems. This means you can just plug in your current external hard drive with data already on it and share it with the rest of the network. The router also can interface with compact hard drives that are USB bus-powered. \n\nRegarding file sharing, the WNDR4000 supports the Windows SMB protocol, which allows any computer in the network to access its storage using a network browser (such as Windows Explorer) without having any additional software installed. Mac computers will automatically detect the network storage share and display that in the Finder. By default, all folders of the connected external hard drive are accessible by everybody. The only way to restrict access to the storage using the router is via the password for the default admin account. For example, you can set it up so that the password is required to gain the read-only or full read\/write access to a particular folder on the external hard drive. Once set, the restriction is applied to anyone wanting to access that folder. This is a primitive, but effective, way to manage network storage. Most NAS servers use more advanced restriction protocols via user accounts. However, considering the fact that this is primarily a router, we were happy with this level of restriction.\n\nThe WNDR4000's network storage also offers media streaming to DLNA-enabled devices, such as the Xbox 360 or PlayStation 3. This feature automatically scans the attached external hard drive for digital contents, making them available to devices within the network. Also, the router can automatically scan for new content when new files are added or repeatedly over a period of time. We tried this out and it worked as intended.\n\nThe router's NAS feature can also handle other NAS functions such as FTP and HTTP server. You can also set up remote connections to access data remotely via the Internet. To do this, however, you will need to use a dynamic DNS service, such as Dyndns.org, unless your connection to the Internet has a static IP address.
