The Linksys WRT54GX Wireless-G broadband router with SRX (Speed and Range eXpansion) technology is a recent addition to a growing number of products equipped with a new technology called MIMO. MIMO is slated for 802.11n, the specification that is scheduled to replace 802.11g next year. Unfortunately, the WRT54GX was consistently outpaced by another MIMO router we tested, the , and was even outperformed in two out of three tests by the , an older-generation Wi-Fi router. Contrary to Linksys's claims, the WRT54GX didn't earn fantastic throughput scores at long distances, either. Though the $199 WRT54GX has a few points in its favor, including three adjustable antennas, WPA security, and an SPI (stateful packet inspection) firewall, it's still no overall match for the $149 Belkin Wireless Pre-N in both performance and price.
The square, silver Linksys WRT54GX router is about the size of a hardback book and looks somewhat intimidating because of the three antennas sticking out of its top panel. The device also has four wall-mounting brackets for hanging the unit free and clear of possible obstructions, such as furniture, that can impede the signal. Nine handy LEDs near the router's top panel light up when it's powered on, when you're engaged in Internet and wireless activities, when you have other devices plugged into the four LAN ports, and when its DMZ capability is enabled.
The package includes an installation wizard on a CD that ships with the router. The wizard walks you through a basic installation process, helping you connect to your broadband modem, choose an SSID (or wireless network name), and set up encryption for your wireless network. With its foolproof design, the wizard helps even those who are new to networking connect the router in a matter of minutes.
The Linksys WRT54GX's browser-based configuration tool offers access to all of the standard Wi-Fi router settings, plus a few nice extras. The configuration tool lets you set up MAC address filters, allowing or denying connections from specific computers based on their hardware, or MAC, addresses. You can also use the configuration tool to adjust WEP and WPA settings. The tool gives you opportunities to keep close tabs on incoming data packets through an SPI firewall and to open up a VPN tunnel through the firewall. Finally, you can use the configuration tool to block users' access to specific Web sites by listing the URLs for those sites.
