Cisco-Linksys BEFSR41 EtherFast Cable/DSL Router with 4-Port 10/100 Switch

Think of the EtherFastCable/DSL Router with 4-Port Switch as a kind of splitter for your Internet connection. Just connect your DSL or Cable Modem to the Router, and all the computers in your household can share the Internet — all at the same time. The built-in 4-port switch lets you attach four local PCs directly, or daisy-chain out to more hubs and switches as your network grows. Once your computers are connected to the Internet through 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 you can share all kinds of files between computers -music, digital pictures, and other documents. Keep all your digital music on one computer, and listen to it anywhere in the house. Organize all of your familys digital pictures in one place, to simplify finding the ones you want, and ease 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 anothers hard drive starts to fill up.The Linksys EtherFast cable/DSL router connects multiple PCs to a high-speed broadband Internet connection or to an Ethernet backbone. Configurable as a DHCP server, the EtherFast router acts as the only externally recognized Internet device on your local area network (LAN). The router can also be configured to block internal users’ access to the Internet. A typical router relies on a hub or a switch to share its Internet connection, but the Linksys EtherFast router channels this connection through the full-duplex speed of its built-in EtherFast 10/100 four-port switch. This combination of router and switch technology eliminates the need to buy an additional hub or switch and serves your network as a completely dedicated, full-duplex backbone. Now your entire network can enjoy broadband Internet connections supported by its switched backbone. This unit requires an external cable or DSL modem with an Ethernet RJ-45 interface. This product comes with a one-year warranty.

Question by Whatever: How do I install a wireless network on a desktop?
I’m running a Windows 7 Desktop computer that does not have a built-in wi-fi connection.
For my internet, all the time I’ve been using a cable Modem (Eminemt dSurf ADSL2/2+)
and now I’ve just bought a Wireless router (Cisco Linksys E1200) with a separate USB wi-fi receiver. (Belkin Surf300). Until now, I’ve managed to SEE my connection and I was able to connect to it, but without any internet connection available. Are the modem and router supposed to be connected to each other or something? If so, how do I connect them properly? I do have technical knowledge about computers, but not when it’s about internet connections… I don’t even know the difference between a modem and a router.

Also, when I try to connect with my mobile phone, I can’t connect to it, meaning it does not have to do with the wi-fi USB thing.

Best answer:

Answer by Whatevers
Yes, the modem has to connect to the router.

Why? Because the router can’t magically connect to the modem.

What’s the difference between the modem and the router? In this case, it’s that the modem has the hardware to talk to the ISP’s network, the router does not.

All you need is an Ethernet cable and if you still have problems call your ISP.

    My PC and my Mac now share high-speed Internet access!, September 4, 2001

    This review is from: Cisco-Linksys BEFSR41 EtherFast Cable/DSL Router with 4-Port 10/100 Switch (Personal Computers)

    We have a PC upstairs, which is our primary computer, and a Mac downstairs in the tv room. I wanted both to be able to share our broadband Internet service. I looked at several routers, both wired and wireless. It came down to the Linksys (wired version) and SMC Barricade Wireless. I kept coming back to Linksys because a friend owns one and raves about it.

    Besides the fact that it looks really cool, it almost took me longer to get it out of the box than it did to set it up. No kidding! Using the QuickStart guide, I was up and running in less than ten minutes. You hook up the necessary cables, restart your computer, log-in to the Linksys website to configure your router, restart your computer again, and you’re good to go.

    I wasn’t as optimistic about setting up my Power Mac G3. However, I was pleasantly surprised and it took me all of about five minutes before I was doing some high-speed surfing on that machine as well. Fortunately, my Mac has an Ethernet port so it was just a matter of attaching the CAT-5 cable from there to the Linksys and setting the TCP/IP control panel to the Ethernet and DHCP options. I saved my configuration, opened up my browser and spent the next two hours high-speed surfing with no problems.

    I have no problem recommending the Linksys, especially for its ease of setup on a PC and Mac network. While I would have preferred a wireless setup, they’ve received mixed reviews and I was concerned about Mac compatibility. After seeing how well my Mac performs with this Linksys, I’m ready to make ours a wired household!

    Easy to Install. Easy to use., May 11, 2000
    By A Customer
    Amazon Verified Purchase(What’s this?)
    This review is from: Cisco-Linksys BEFSR41 EtherFast Cable/DSL Router with 4-Port 10/100 Switch (Personal Computers)

    I worried this product would be hard to install, configure and use. This sounds silly since I’m an engineer working at a dot-com company, building a large Internet network. Even engineers get stuck with computer hardware they can’t get to work. Also, being net savvy, I tend to want my network hardware to work MY way and not in some configuration deemed “good” by marketing monkeys. All fears quickly faded, however as the router was up and running with my network 15 minutes after opening the box.

    Ease of use is important, as I frequently distrust technical support for networking products. No fault of Linksys, but years with inept customer service apes, trained only to hold phones, ruined me. If I can not get a product to work in short order when other, equivalent products exist, I quickly return, exchange and try again. Thankfully, I did not have to do so. The Linksys jumped all hurtles without effort.

    Ease of use goes past the install to the packaging and into the web-based configuration. The packaging comes with a quick start guide. Smart. Impatient males with more eagerness than brains don’t want to read manuals, even short ones. The quick start has everything you need to get online in short order. If you need the advanced features, like port redirection, a DMZ host, or PPP over ethernet, the manual is friendly and the configuration screens are kind. Five minutes after surfing the web, I reconfigured my PC to have a static IP address (rather than the DHCP generated address, given to me by the quick start guide), and set up port redirection for my web server.

    DHCP is great, especially if you take tote your laptop between home and work. DHCP is a service, run on a network, allowing computers on the network to ask what their IP addresses, gateways, DNS servers and subnet masks are. The DHCP server replies, allowing computers to dynamically configure themselves based on what network the computer is on. Thus, you can conveniently carry your laptop into work, hook it up without reconfiguring the networking. If you’re me, you’re likely too lazy to set up a UNIX computer on your network just for a DHCP server. So, having the Linksys Cable/DSL router provide DHCP is a big bonus.

    Net novices may wonder if this router is a risk to have. With all the media attention, you likely think an army of computer and network savvy teens are just waiting for you to go online, so they can infect and hack your computer. I’ve never had a problem, but then, I’m cautious from where I download software and with whom I interact. One risk is placing a bad password on your router, allowing others to reconfigure your network. I envision several lazy people not bothering to change the default password on their Linksys routers, creating some minor havoc.

    However, because the router uses network address translation, you have the potential to be safer as outsiders see only the IP address of your router and not your host. So far as I know, the only listening port on the router is the embedded wed server and any in-bound port-forwarding you set up, so people trying to get in, from the outside, will likely rely on you to do something dumb. A few dumb things include an easily guessed password on the router — your first name, or the word “router” are really terrible ideas — downloading software from any web page with the words “d00d” or “kewl,” or setting up a web server from an old Linux distribution without checking CERT advisories for known security holes. More dumb things exist. Use common sense, but never fear making mistakes; it’s just a computer.

    If you have several computers in your home and want them all to be networked, the Linksys can do the job. Yes, only 5 ports exist on the back, but 10 megabit per second (MBPS) hubs are less than $30 and 100 MBPS hubs are around $100. Multiples of either hub can be added, to get up to 255 computer on your network. Though, if you have 255 computers, just using hubs will lead to frightening performance problems, but one hopes, anyone with so many computers, knows better.

    Incredible value, May 22, 2000
    James McCarty (Hilliard, Ohio USA) –

    This review is from: Cisco-Linksys BEFSR41 EtherFast Cable/DSL Router with 4-Port 10/100 Switch (Personal Computers)

    The combination of features and the price make this a great unit. Before I start, a word of warning – I use the product with RoadRunner in Columbus, Ohio; we are a pure DHCP with no login style of cable system; your “mileage” may vary depending or your ISP.

    I had this unit setup and working in 5 minutes. 1 – Turn off the cable modem and your PC. 2 – Install the DSL router. (Use good quality NON-crossover cables.) 3 – Turn on the cable modem. 4 – Turn on the DSL router. 5 – Turn on the PC. You are done. For most people, this is all that is needed.

    Open your browser and point it to and check the release level of the software. Then, check LinkSys and verify you have the latest version. A couple of the early releases had a few “gotchas”.

    I have used this router with a combination of machines running NT 4.0, Windows 98, Windows 2000 (Professional and Advanced Server), and Red Hat Linux with no problem (There shouldn’t have been since this is a standard DCHP server and NAT box.)

    I just finished a 60Mb down load with no problem.

    Some people may need more functionality than this box delivers (advanced filtering, etc.) This is NOT a $2000 Cisco router and it doesn’t try to be. Check you needs and if you are a typical SOHO user; this unit will most likely fill the bill.

  4. cable connects to modem
    modem connects to router
    router connects to computers either with a cable or wireless – if it is wifi.
    modem converts cable signal to ethernet.
    router distributes ethernet to multiple devices either on a wire or wireless.
    this includes computers, mobile phones, tablets, etc.

    Once connected, u must configure the router.
    For a wired connection, there is no config necessary – so connect ur computer with a wire and configure the wireless.
    Actually, once connected the wireless is active and u should be able to connect without a passphrase – although some newer routers already have the wireless secured with a passphrase code on the name tag.

    Some routers have WDS which is a one button configure – but ur on ur own there – I never use it.
    u must (should) configure wireless security after that it is about usage.
    IE, if u have an xbox, it should have a static IP. etc.

  5. There are many different things that are going on here, that may be why you’re having issues. Without knowing what your original configuration was, it will be more difficult to tell you how to fix it.
    You said you have a desktop computer, and I’m guessing your original configuration had the computer plugged directly into the Eminemt dSurf ADSL2/2+. This particular DSL modem has a router/firewall built into it, and is an acceptable way of using it. If the DSL modem is close to the computer, there should be no need for you to use the USB wireless adapter, and connect wireless.
    Are there other devices you’re trying to get hooked up with the wireless router? If that is the case, there are guides online to help you through the process, but it will take a degree of knowledge to do so. You would basically be hooking up two routers to one another, which takes a little more of an advanced configuration. Mainly, you need to make sure the IP addresses of the 2 routers don’t match, and connect from one set of the numbered ports on the DSL router, to one of the numbered ports on the wireless linksys router. This will basically turn the wireless router into a switch, but will allow you to have internet access through the wireless router.
    In any case, if possible, you should keep your desktop computer hooked up to the Eminemt dSurf ADSL2/2+ with a wire (ethernet cable) if possible, as this will give you the best connection speeds. Unless you are trying to get other devices connected through WIFI(phone, tablet, or laptop), you shouldn’t need the wireless router at all.
