Linksys WRT54GX

Internet-sharing Router, 4-port Switch, with a built in speed and range enhanced Wireless-G (802.11g) Access Point
Shares a single Internet connection and other resources with Ethernet wired, Wireless-G, -B, and other SRX devices
New SRX technology: the farther away, the more advantage -- up to 8 times faster than standard Wireless-G (802.11g)
SRX also increases wireless range by up to 3 times and reduces dead spots in coverage area


The Wireless-G Broadband Router with SRX is really three devices in one box. First, there's the Wireless Access Point, which lets you connect Wireless-G, Wireless-B, and other performance-enhanced SRX devices to the network. There's also a built-in 4-port full-duplex 10/100 Switch to connect your wired-Ethernet devices together. Finally, the Router function ties it all together and lets your whole network share a high-speed cable or DSL Internet connection.
The Wireless-G Broadband Router with SRX combines smart antenna technology with standards-based Wireless-G (802.11g) networking. By overlaying the signals of two Wireless-G compatible radios, the "Multiple In, Multiple Out" (MIMO) technology effectively doubles the data rate. Unlike ordinary wireless networking technologies that are confused by signal reflections, MIMO actually uses these reflections to increase the range and reduce "dead spots" in the wireless coverage area. The robust signal travels farther, maintaining wireless connections up to 3 times farther than standard Wireless-G. And the farther away you are, the more advantage you get -- the higher data rate and reflection-friendly technology can yield up to 8 times more throughput than Wireless-G in some situations. The router avoids interference by dynamically switching to the clearest channel available. Even your standard Wireless-G and -B equipment will work better when communicating with SRX-enabled devices.
To help protect your data and privacy, the Router can encode all wireless transmissions with industrial-strength WPA encryption. It can serve as your network's DHCP Server, has a powerful SPI firewall to protect your PCs against intruders and most known Internet attacks, and supports VPN pass-through. Configuration is a snap with the web browser-based configuration utility.
With the Linksys Wireless-G Broadband Router with SRX at the center of your home or office network, you can share a high-speed Internet connection, files, printers, and multi-player games with flexibility, speed, and security!

Linksys WRT330N


The Wireless-N Gigabit Gaming Router is really four devices in one box. First, there's the Wireless Access Point, which lets you connect to the network without wires. There's also a built-in 4-port full-duplex 10/100/1000 Switch to connect your wired-Ethernet devices together at up to gigabit speeds. The Router function ties it all together and lets your whole network share a high-speed cable or DSL Internet connection.
We've also included a Network Optimizer that applies various Quality of Service (QoS) techniques to your network traffic to make sure that time-sensitive applications like online and local network gaming run smoothly. It automatically determines what data is time-sensitive and what isn't, and prioritizes delivery of that data to its destination, ensuring the best-possible performance for the various types of data that go through your network.
The Access Point built into the Router uses the very latest wireless networking technology, Wireless-N (draft 802.11n). By overlaying the signals of multiple radios, Wireless-N's "Multiple In, Multiple Out" (MIMO) technology multiplies the effective data rate. Unlike ordinary wireless networking technologies that are confused by signal reflections, MIMO actually uses these reflections to increase the range and reduce "dead spots" in the wireless coverage area. The robust signal travels farther, maintaining wireless connections up to 4 times farther than standard Wireless-G.
With Wireless-N, the farther away you are, the more speed advantage you get. It works great with standard Wireless-G and -B equipment, but when both ends of the wireless link are Wireless-N, the router can increase the throughput even more by using twice as much radio band, yielding speeds up to 12 times as fast as standard Wireless-G.
To help protect your data and privacy, the Router can encode all wireless transmissions with industrial-strength 128-bit encryption. It can serve as your network's DHCP Server, has a powerful SPI firewall to protect your PCs against intruders and most known Internet attacks, and supports VPN pass-through. Configuration is a snap with the web browser-based configuration utility.
The incredible speed of Wireless-N and gigabit wired networking is ideal for media-centric applications like gaming, streaming video, and Voice over IP telephony, and gives you plenty of headroom to run multiple media-intense data streams through the network at the same time, with no degradation in performance. The Linksys Wireless-N Gigabit Gaming Router optimizes your online gaming, lets you share a high-speed Internet connection, files, and printers, and run media-intensive applications at amazing speeds -- all without the hassle of stringing wires!

The Access Point built into this router uses the very latest in wireless networking technology -- Wireless-N (draft 802.11n). By overlaying the signals of multiple radios, Wireless-N's Multiple-In, Multiple-Out (MIMO) technology multiplies the effective data rate. Whereas ordinary wireless technologies are confused by signal reflections, MIMO actually makes use of these reflections to increase the range while reducing dead spots in the coverage area. This means the signal travels farther, maintaining wireless connections at up to three times the distance of standard Wireless-G, so the farther away you are, the more speed advantage you get. This Wireless-N router is fully backward compatible, so it works great with standard Wireless-G and -B devices, but when both ends of the wireless link are Wireless-N enabled, the router can increase the throughput even more by using twice as much radio band. This allows speeds up to 15 times that of standard Wireless-G. As a further convenience, unlike other speed-enhanced technologies, Wireless-N can dynamically enable this double-speed mode for Wireless-N devices, while still connecting to other wireless devices at their respective fastest speeds. For especially congested areas, there is a good neighbor mode that makes sure the router checks for other wireless devices in the area before gobbling up all the available radio band.
To help protect your data and privacy, this router can encode all its wireless transmissions with iron-clad, 256-bit Wireless Protected Access (WPA2) encryption. This unit can also serve as your network's DHCP server, includes a powerful SPI firewall to protect your all your PCs against intruders and most known Internet attacks, and supports VPN (Virtual Private Network) pass-through for the ultimate in network security.

Linksys WRT54G Wireless-G Router


Editors' note: The rating and/or Editors' Choice designation for this product has been altered since the review's original publication. The reason for this is simply the general improvement of technology over time. In order to keep our ratings fair and accurate, it's sometimes necessary to downgrade the ratings of older products relative to those of newer products. (12/9/04) The Linksys WRT54GS Wireless-G Broadband Router with SpeedBooster makes it easy to set up a typical home or office network, and it comes with all the documentation you need to get it up and running. It touts a wealth of advanced networking and security features, and it's fast, especially in networks with both 802.11g and 802.11b connections.
Setup and ease of use of Linksys WRT54GS Wireless-G broadband routerThe illustrated Fast Start guide for the Linksys WRT54GS Wireless-G Broadband Router with SpeedBooster walks you through the basic setup, which includes connecting the router to your computer and broadband modem, configuring all the computers on the network to work with the router, and configuring the router. The Fast Start guide is more thorough than others we've seen, with plenty of images and screenshots illustrating the setup process. We were glad to see brief explanations of basic networking terms, such as the difference between static and dynamic IP addressing and what to do if your DSL provider uses PPPoE. The guide also describes how to connect to the WRT54GS's browser-based configuration tool if you need to tweak the router's configuration--for example, to supply the router with a static IP address. No quick-setup guide can cover all possible networking scenarios, but Linksys's step-by-step guide does an excellent job rounding up the usual suspects and making it easy for most homes and small offices to set up a network in a few minutes. In most cases, you need only to plug in the router and connect the cables. For more complicated setups, Linksys includes a thorough user guide detailing the WRT54GS's diverse features.
Features and security of Linksys WRT54GS Wireless-G broadband routerAlthough the Linksys WRT54GS Wireless-G Broadband Router with SpeedBooster is easy to set up, you'll find a number of advanced features and configuration options under the hood. The Linksys WRT54GS's browser-based configuration tool gives you access to the router's networking and security settings, such as DHCP server and client settings, firewall settings, and wireless encryption settings. The router also comes with two types of firewalls. One is a Stateful Packet Inspection (SPI) firewall that makes sure packets are part of a legitimate connection; the other is a NAT firewall that effectively hides computers behind the router. You can lock your network down even tighter by configuring the router to block services such as FTP and Telnet. A DMZ function located on the configuration tool's Applications and Gaming tab lets you place one computer outside the firewall, which can be useful for Internet gaming and videoconferencing. The Linksys WRT54GS also lets you set up access-control policies that grant Internet access to specific computers on your network at predetermined times of day and days of the week. If you telecommute, the router's VPN pass-through support will help get you to work. The Linksys WRT54GS router also has good wireless security. You can configure it to use WEP or WPA. WPA is stronger than WEP, but it's important to have both options, because you may want to connect to older 802.11b devices that lack WPA support. We also like that you can turn off the beacon on the WRT54GS's integrated 802.11g access point. This helps protect you from uninvited guests by stopping the access point from advertising its presence to the world. The Linksys WRT54GS router comes with removable antennas, giving you the option of attaching high-gain antennas to the unit to increase its range. Our only gripe was that the router lacks a mounting bracket.
Performance of Linksys WRT54GS Wireless-G broadband routerThe Linksys WRT54GS Wireless-G Broadband Router with SpeedBooster is one of a growing number of wireless routers touting proprietary speed enhancements. Like the D-Link DI-624 and the Netgear WGT624, the WRT54GS SpeedBooster router includes a technology (in this case, Broadcom's Afterburner) that substantially increases wireless network performance. The enhancements kick in only if all the devices on the network are playing by the same proprietary rules; otherwise, the device scales down to standard 802.11g speeds. We think that this limitation makes the SpeedBooster enhancement (and similar Turbo or Super-G offerings from vendors such as D-Link and Netgear) more of a marketing gimmick than a significant feature. Proprietary solutions depend on networks molded out of homogenous gear, limiting your purchase choices and tying you to a single vendor. On the other hand, the Linksys WRT54GS Wireless-G Broadband Router with SpeedBooster does a fine job supporting standards-based equipment from other vendors, even older 802.11b gear. In CNET Labs' mixed-mode tests, which measure throughput when both 802.11g and 802.11b transmissions occur simultaneously, the WRT54GS delivered the fastest speeds we've seen, clocking in at 25.8Mbps. The Linksys also went the distance, stretching as far as 200 feet in our range tests.
