Product Description

From the Manufacturer

The Wireless-G Notebook Adapter with SRX400 is the simple way to add or upgrade wireless connectivity in your notebook computer. Just slide it into your notebook's PC Card slot and enjoy high-speed wireless network access while retaining true mobility.

The Wireless-G Notebook Adapter with SRX400 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.

With SRX, the farther away you are, the more speed advantage you get, and SRX400 works great with standard Wireless-G and -B equipment, and other flavors of Linksys SRX. But when both ends of the wireless link are SRX400, the network 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 -- faster than 10/100 wired network speeds! But unlike other speed-enhanced technologies, SRX400 can dynamically enable this double-speed mode for SRX400 devices, while still connecting to non-SRX400 wireless devices at their respective fastest speeds. And SRX400 is a "good neighbor", always checking for other wireless devices in the area before gobbling up the radio band.

Once you're connected, you can keep in touch with your e-mail, access the Internet, and share files and other resources such as printers and network storage with other computers on the network, wherever you wander. At home, you can surf the web or use instant messaging to chat with friends while sitting out on the patio. You'll also be able to connect with any of the growing number of public hotspots springing up in coffee shops, airport lounges, hotels and convention centers. Your wireless connection is protected by industrial-strength WPA encryption. The included Setup Wizard will walk you through configuring the adapter to your network's settings, step by step.

Get your notebook connected to Wireless-B, Wireless-G, and SRX wireless networks with the Wireless-G Notebook Adapter with SRX400 from Linksys.

5.0 out of 5 stars Great Product!, December 14, 2005

This review is from: Cisco-Linksys WPC54GX4 Wireless-G Notebook Adapter with SRX 400 (Personal Computers)

I bought the WRT54GX4 yesterday along with a WPC54GX4 PCMIA card for my laptop. My old WRT54G died after 2 3/4 years of service. Linksys will replace the old unit under warranty, but I run a small business and couldn't wait for a replacement. I also found the wireless link between the WRT54G and the WPC54G to be somewhat spotty with the wireless card not catching the router signal all to often so an upgrade was in order anyway.

I installed the WRT54GX4 router with no problem and found that my wired connection had better internet response although I know of no reason why that should be the case. I also tested it with the the laptop with the OLD WPC54G card and the difference was amazing. All of the dead spots in my home were gone, the signal was strong and the transmission rate was inproved. If you want to save a few bucks, but need an improved wireless network, the router will do that even with standard G product in my brief experience.

I next installed the WPC54GX4 card in the PCMIA slot in my laptop. Installation was a breeze. As expected signal strength was strong throughout the house and the data transfer rate was consistantly 240Mbps! To check the range, I put the laptop in the car and concluded I could easily keep connected if I were visiting any of the neighboring houses. The card also picked up a lot of other networks in neighborhood (most of which were not encrypted).

These are not cheap products, but they work and are well worth the money if you want a great wireless network.

5.0 out of 5 stars Very Solid Product for Business or Home Use, July 25, 2007

This product is a good solid, stable product that works well in a business environment. SRX 400 works well to boost signal strength and to give you that extra bar of signal when you need it. My mobile users with this card can routinely get a usable, solid signal where reception was poor before.
-
As always, I never recommend installing the Linksys application, but instead installing the card and then using the Windows wizard to install just the driver from the CD. I recommend using the Microsoft Wifi control and third party applications sometimes cause conflicts.
-
Again, great for home or business use. As an IT professional this is the card I would equip users with if their notebook was not equipped wifi or if their internal wifi was not performing up to the user's desire.
-
As a side note, I would recommend that with all technology items, that you install the latest firmware straight away. I suggest that before ever calling tech support or writing a negative review online. More times than note, a firmware update has resolved my problem unless an item was damaged in shipping. In that case it is not a poor reflection of the product, but rather the delivery service. Please consider that when writing reviews.

I installed a wireless network using the WRT54GX4 and three WPC54GX4 cards in desktop pc using a pci to pcmcia bridge card. I also have a WPS54G print server on my network. All use WPA2 for security. The speed is awe inspiring for a wireless network, as well as the range and coverage. I give LINKSYS an A++ on this one.
