Amazon.com Product Description
Amazon.com Product Description The next generation of wireless technology has arrived, with the Linksys WRT54GX4 Wireless-G Broadband Router with SRX400 leading the way. Although it's technically considered a router, the Linksys WRT54GX4 is much more than that. Based on "multiple in, multiple out," or MIMO, technology that effectively doubles the data rate, this is actually three high-performance devices in one. First, there's the Wireless Access Point, which lets you connect to the network, as the name suggests, without wires.

Then there's the built-in four-port full-duplex 10/100 Switch to connect your wired Ethernet devices together. Finally, there's the actual router that ties it all together and lets your whole network share a high-speed cable or DSL Internet connection. With the Linksys WRT54GX4, the days of stacking boxes connected by a confusion of tangled wires are thankfully over.
SRX: The Future of Wireless Networks Is Here
The Linksys WRT54GX4, like all of Linksys's SRX400 products, is based on MIMO technology, a key component in the upcoming Wireless-N standard (802.11n). By overlaying the signals of two Wireless-G compatible radios, MIMO has the capacity to double data transfer rates. In fact, the maximum wireless data transfer rates of the SRX400 actually exceed the capabilities of the traditional wired Ethernet 10/100 data ports that are in place on most computer networks. It's that fast. And by using the network's signal reflections that usually hinder performance in typical wireless products to increase range and reduce "dead spots" in the wireless network, SRX400 effectively increases the coverage area of the network by up to three times that of Wireless-G. In short, not only do you significantly increase your data transfer speed with Linksys WRT54GX4, but you can vastly increase the distance you can send our signal as well.
Of course, you don't want to transmit sensitive information without making certain the network is secure. To help protect data and privacy, the Linksys WRT54GX4 can encode all wireless transmissions with industrial-strength WPA (Wi-Fi Protected Access) encryption. It can serve as a network DHCP server, supports VPN pass-through, and has a powerful SPI (Stateful Packet Inspection) firewall to protect against intruders and most known Internet attacks. Enabling these security features on the router is easy with the Linksys Web browser-based configuration utility.
And when your computers are equipped with the Linksys WPC54GX4 Wireless-G PC Card, you will see unparalleled throughput, significantly reduced dead spots, and a dramatically increased wireless range compared to traditional Wireless-G networks.
Does this mean that you'll need to convert all of your wireless equipment to SRX400? Not by a long shot. While SRX400 works optimally with other SRX400-enabled devices, it works just fine with standard Wireless-G and -B equipment. In fact, the Linksys WRT54GX4 router has a "good neighbor" policy that ensures that it is always checking for other wireless devices in the area before gobbling up the radio band. While it can dynamically enable a double-speed mode for SRX400 devices, it's designed to seamlessly operate with other 802.11 certified wireless devices at their respective fastest available speeds. And best of all, it enhances the performance of non-SRX devices by allowing them to connect at further distances than standard Wireless-G routers do. But when both ends of the wireless link are SRX400, the router can increase the throughput even more by using twice as much radio band, yielding speeds up to 10 times as fast as standard Wireless-G.
The bottom line is that with the Linksys Wireless-G Broadband Router with SRX400 at the of your home or office network, you can share a high-speed Internet connection, files, printers, and multiplayer games at speeds faster than those of 10/100 wired networks, but without all the hassles of wires or inefficient wireless connectivity.

"Works very well when set up properly." 2009-04-09By
B. Waggoner (Nevada)
My application is wireless-G in the suburbs with Windows XP SP2 and a cable modem upstream. Windows shows faint signals coming from 4 neighbors in addition to my strong signal. Initial setup was very easy, but my wireless link kept disappearing at random, sometimes coming back in a few minutes, other times not for several hours (unable to reconnect). I used Internet Explorer to log onto the router setup menus 4 times in as many days, changing the wireless channel number, disabling wireless-B, and disabling the "adaptive channel expansion" option. Finally I found a channel with no interference, and the router works perfectly. Having a router with increased range not only boosts your own signal, but also interferes with neighbors and leaves your own router more open to interference from neighbors. So the router works perfectly once you find a wireless channel not being used by anybody else in the neighborhood, but there's no excuse for Windows XP and/or the Linksys router not helping you find an unused channel in the first place. Interference from neighbors on the same channel no doubt causes many of the bad reviews herein and Linksys product returns, so I cannot fathom why they apparently haven't thought about this fundamental issue and come up with a good (i.e. automatic) solution.
"the router did not work" 2008-11-13By
Jan Travis FulghumThe router did not work! Linksys tech support is awful and a waste of time! DO NOT BUY THIS PRODUCT!!!
"Linksys WRT54GX4 Wireless-G" 2008-05-10By

Linksys products over the years have proven to be less than reliable and the WRT54GX4 may be the culmination of this dubious achievement status.
Like all Linksys products the main issues are functionality, consistency and ease of implementation. I have only thirty years experience in the IT world which perhaps under qualifies me to properly setup these units.
Avoid using these overpriced, under performing products whenever possible and you'll be much happier or disregard this review and find out why millions of people are on a first named basis with Rashis (from Bombay) one of the dozens of friendly customer support individuals sub-contracted by the company to man their very busy customer support lines 24/7. Too bad they can't ad a few more days to the week to take some of the pressure off these nice people.
"great product" 2008-04-07By
Thomas J. LundI got this router and am very pleased with the ease of set-up and the quality of performance.
"AS GOOD AS N ROUTERS OUT THERE!" 2008-03-08By
J. Reyes (Los Angeles, CA)
After trying to replace the WRT54GX with an N router to get better range, I discovered this router gives me better range than all the N routers I tried: the D-Link DIR-655, the Negear RangeMax Dual Band Wireless N router, and the Belkin N1 wireless router. Okay people, my room is VERY FAR away from the router location, and at least five walls stand in between. I get one bar from the WRT54GX, but it works. The Netgear and the Belkin routers didn't ever register a bar. The D-Link worked but dropped frequently and then locked me out. On a wireless G signal, this router appears to be as fast as the N routers. I have the SRX400 wireless card that goes with it, and when paired up with this routers, its speed is on par with any N card, N router configuration I tried. It's lighting fast. Shame on Linksys for discontinuing support for Windows Vista on adapters for this router, for giving up on its technology basically. It's awesome. I love it and in my opinion, it's the best router out there for my purpose. On a last note, it's been ultra reliable.
