Product Description

Product Description

Think of the Linksys BEFW11S4 Wireless-B Broadband Router as a kind of "splitter" for your Internet connection. Just connect your DSL Modem to the Router, and all the computers in your household can share the Internet -- all at the same time. You can connect your home computers directly to the Router with Ethernet cables, or put wireless network adapters in them and communicate over radio waves, saving the trouble and expense of running cables through your house. Once your computers are connected to the Router, they can communicate with each other too, sharing resources and files. All your computers can print on a shared printer connected anywhere in the house. And your computers can share all kinds of files -- music, digital pictures, and documents. Keep all your digital music on one computer, and listen to it anywhere in the house. Organize all of your family's digital pictures in one place, to simplify finding the ones you want, and easing backup to CD-R. Play head-to-head computer games within the household, or against Internet opponents. Utilize extra free space on one computer when another's hard drive starts to fill up. Your home network is secure, too. All wireless communications are protected by 128-bit encryption. The Router helps keep intruders out of your computers. NOTE: This Router is missing the AC/DC power adapter

The EtherFast wireless access point and cable/DSL router features a router, a four-port 10/100 switch, NAT firewall, and an IEEE 802.11b wireless access point (11 Mbps). This all-in-one device allows wireless PCs and wired Ethernet PCs to access a single broadband Internet connection for sharing IP addresses, files, printers, and other network resources while conserving desktop space. The built-in four-port switch enables wireless and wired notebook and desktop PCs to share high-speed Internet access.

Configurable as a DHCP server for your existing network, this router acts as the only externally recognized Internet gateway on your LAN and serves as an Internet NAT firewall against unwanted outside intruders. It can also be configured to filter internal users' access to the Internet. The 4-port switch dramatically increases the speed of multimedia and gaming connections.

This device comes with a one-year warranty and free 24/7 technical support.

Wireless networks are rapidly becoming more popular and coming down in price. Since they don't require cables, you can use the devices anywhere in an office or home, even out on the patio. There's no need to roll out an Ethernet network cable to each room of a house; you can network anywhere--without wires. Outside the home, wireless networking is available in hotspots at coffee shops, businesses, and airports--great when you're on the road and need to get some work done. For convenience, wireless networking is the answer.

Which Wireless Standard Is Right for Me?
Now that you've decided to create a wireless network, the next step is to figure out which wireless standard to use.

Basically, a standard is a set of specifications for a device. All devices that follow a specific standard share operating characteristics, such as the radio frequency used and maximum data transfer speed.

For wireless networking, there are three standards to choose from at this time:

  • 802.11b
  • 802.11a
  • 802.11g

I am not sure what all the others had problems with but my Linksys worked great out of the box. Setting it up I had an issue that was easily fixed by calling tech support,(only 5 min wait and worth it, the technician was very good). My laptop which will be connecting wirelessly was not connecting no matter what I tried. It turns out that you can't run wireless cards and ethernet cards (mine was built in} at the same time because the machine will always default to the ethernet card. Which is exactly what was happening. We removed the driver for the ethernet card and it began to work great right away. Everything else about the setup was fairly simple and went very smooth the directions were easy to understand. I especially liked the quick installation sheet which is what I used to setup with.
I highly recommend this product and would buy it again if I had to do it all over. The distance of the wireless machine is really dependent on terrain. But for my two story house it was great. The only weak spot being downstairs in the opposite direction of the linksys base as far as I could go. However it still worked and was quite able to handle downloads even at the weakest point. You just can't go wrong till they come out with a new beakthrough in technology. But even then the prices will be to high in the beginning. For instance the new 802.11a is several hundred dollars more expensive then this machine. And for what you get I just don't need it.
This is a winner. The newest version of the product is BEF11S4 VER 2. Many of the reviews done in this section were about the
BEF11S4 its the same model number but lacking the ver.2 after the BEF11S4.
The newest version has fixed most of the bugs of the previous version. Good Luck!!! A very satisfied consumer

This unit accomodates both hard wired networks (up to 4 devices) and wireless networks (use the Linksys cards - others may not be compatible) and serves as a router and access point. Setting it up was incredibly simple (I updated the firmware right away) and the default settings worked perfectly with my cable (Road Runner) ISP. I did implement MAC cloning on advice from the Linksys website (a great source for info on configuring this for various DSL/cable ISPs) later just in case. This was easy with the web-based configuration software.
You do have to know how your ISP works. I'm assuming I could not disable DHCP because Road Runner uses it. Since I couldn't give my machines static IP addresses, I sometimes have to change the port forwarding configurations depending on which IP address the router assigns each machine (we turn off the machines at night). You also need to reconfigure some of your internet software to work behind a firewall if they haven't been set that way all ready. And in some cases, I had to disable my personal firewalls (we use Sygate, AtGuard or Zone Alarm) for internet software to work (particularly FTP clients).
The wireless range (we have 3 hard wired computers and a couple of wireless laptops) is not spectacular (50' radius) but adequate for our purposes. Would have appreciated some input from the manufacturer about effective placement of the unit for optimal wireless performance.
If you're willing to do a little tweaking now and then and don't need extensive wireless range, this is a great all-purpose device.

I have read nothing but negative reviews about this product. Has anyone ever seen so much negativity on one product??? It's insane. Despite all this, I decided to put's 30-day return policy to the test and order this anyway. I also ordered the Linksys WPC11 Instant Wireless Network PC Card. I have two computers I networked, a Compaq Presario 600Mhz Intel Celeron Laptop and a Compaq Presario PIII 700Mhz desktop. Only one wireless card was purchased for the laptop; the desktop was plugged in directly to the hub using a CAT5 cable. That's it. So, I spent exactly $350.00 and the price has even seemed to go down more (I may complain about this and try to get a rebate, but that's not the point I want to make here). So, I open it up expecting any of the numerous terrible things so many of the so-called "I've been networking computers for years and this is the worst piece of hardware ever prodcued, folks" experts have to say about it. I was pleasently surprised. It works. The router works very well, which so many people said was a terrible, worthless piece of junk and even the card which was supposed to be fatally flawed works well. It does not drop off after walking 10 feet away, it does not die after the first 5 minutes, it has not crashed either of my computers. Not even once. I've got a cable connection, not DSL. The laptop uses Windows ME and the desktop uses Windows 98. The internet connection was relatively easy. Work slowly. Read the instructions very carefully. I spent about 45 minutes making absolutely certain I had every piece of information ready for the installation. It's all spelled out in the instruction manual so I won't bother going into too much detail here. Just hit START, hit RUN and type "winipcfg".Read more ›
