Question about Linksys BEFW11S4 Wireless-B Broadband Router (12503024)

Securing my wireless linksys BEFW11S4 ver. 4

There are 3 laptops in my house hold that use this wireless router and it works fine but I think my neighbors may be using it too, how do I set it for only our computers?

It is a BEFW11S4 ver. 4

I have never done this before so I need step by step instructions including how to access my Linksys for resetting, and does this need to be done on a computer that is currently using the wireless? and if so do I need to set a network for the wireless and if so how is that done?

best regards
Shar

    I tried as you said eecom but I was unable to log into the Linksys router, I connected directly with a eithernet cable, opened my browser, put in http://192.168.1.1 but I got this message:
    but yet I still had an internet connection, I am wondering if it is because I have my Lynksys connected to a DSL router, I also tried to log in to my linksys after disconnecting it from the DSL router and still i could not log in to it but also got a stack overflow error at line 0.



    not sure what to do yet, but thank you for trying.

    best regards,

    Hi eecom,



    Thank you for replying, yes I am running windows but I am running XP Pro so the Command prompt is not located where you had said but I did locate it and here is the picture of my IP::




    First I did as you said to reboot the router and it still was the same so I tried this new IP and I got this window:


    For some reason I have a feeling that the code I got in the Command Prompt for the Default Gateway is for my DSL router and not for the wireless Linksys router, is this possible?

    I did type the word admin for the password but as you can see it failed.



    Best regards,

    Shar

Hello,

I’ll be pleased to help if I can. To answer your last question first, this router is already set up for wireless networking, so nothing further needs to be done with regard to that.

However, to prevent others using your connection, it's necessary to set up wireless security. There are four main steps, which are the same for most routers:

1) Login to your router, using a wired connection
2) Change the router login password
3) Change the network name (SSID)
3) Enable WPA encryption

Here are the details:

1) Login to your router, using a wired connection.
First, you will need an Ethernet cable to connect one of your computers to the router. This cable just plugs into a spare port on the back of your router, while the other end plugs into the Ethernet port on your computer (looks like this picture).

When you are connected, open a web browser on your computer. Type the router’s IP address into the address bar, which is http://192.168.1.1 for this model. (Note, there is no ‘www’)

You should then see a popup box, prompting you for a username and password. If these have not been changed, leave username blank and enter password: admin

If you log in successfully, you should then see the Linksys router configuration screen.

2) Change the router login password.
To set a new password, go to Administration > Management. Set and confirm a new Router Password. On this screen, I would also recommend that ‘Remote Upgrade’ and ‘Remote Administration’ are disabled. Click ‘Save Settings’ when finished.

(Tip: write the password on a label and stick it on the router, or keep it somewhere safe. )

3) Change the SSID (router name):
Go to Wireless > Basic Wireless Settings. Change the ‘Wireless Network Name (SSID)’ from the default, to anything you like, that you can remember. It is case sensitive, and you can use up to 32 letters –but do not use something that could identify you, or your location.

At this stage I’d recommend that SSID broadcast remains enabled.

4) Enable WPA encryption
Go to Wireless > Wireless Security. Enable Wireless Security. Under ‘Security Mode’ you have a number of options for encryption, but I would pick WPA-Pre-Shared Key, which is very secure and good for most equipment.

Under ‘WPA Shared Key’ you need to enter a network key. This is a long password, or passphrase, between 8 and 63 letters/numbers long. This can be any series of letters/ numbers, or you can use a phrase with numbers
( eg: 456the51stSTATeOFtheUSA1599 ). It is case sensitive. The stronger the network key the better, if you are very concerned about security.

Note down the network key carefully. You will need this to connect wirelessly. (The network key may also be called the WPA shared key, PSK, WPA-PSK, pre-shared key, security key, passphrase, or authentication key). Click ‘Save settings’ when finished.

That's it, you have done enough to secure your network, and can close the screen.

There are further security options to enable if you wish, but these three are the most important.

When you next connect wirelessly, you should see your network with its new name in the 'available wireless networks'. When you attempt to connect, you are asked for the network key you set in Step 4. If all goes well, you can then save this and will connect automatically in future.

Hope this helps you. Please come back to Fixya if this doesn't work, or if you need help with any of it.

    OK! Many thanks for the feedback, and the screenshot.


    The advice given depends on your being able to log in to the router, which you did perfectly correctly. However, as the default IP address for your model has not worked, you could now check if yours uses a different IP address.

    First, I don’t know if you have tried re-booting the router, but this might be a good step to take next. Then return to the computer that is wired to the router. Assuming you’re using Windows, go to Start > (All) Programs > Accessories > Command Prompt , to pull up a special command line window.

    In the window, type ipconfig and press return.

    In the output you see, the Default Gateway should show the router IP address. For example, here's mine:




    Try logging in with your Default gateway IP address instead.

    If you find it’s the same – and/or it still doesn’t work – please come back to Fixya. Good luck....

    Hi again...thank you for letting me know - and for the screenshots, which are excellent.

    Your question about the modem’s IP address was interesting: and I can’t be 100% certain of the answer, since I’m not a professional. However, to the best of my knowledge, if your computer is connected directly to your router via ethernet cable, the default gateway is the router IP address.

    The popup prompt at least suggests we are on the right track. The next puzzle is why the default username and password do not let you in. These were taken from Linksys’ own user manual for this model.

    Could the login password have been changed already – for example, during the initial setup? Otherwise, was the router provided by your ISP? Sometimes they are issued with proprietary firmware and the ISP’s own default password. If this is the case, a visit to your ISP’s website may help.

    Sorry not to be more help at this stage, but it’s worthwhile trying to track down the password if there is a chance it has been changed. All the best...

HP laptop not recognizing Linksys Wireless B Security Key..


The WEP encryption is consist of 10 characters for 64 bit hex, 128 bit hex is 24 characters and WPA is 8 to 63 characters. So it seems that you have a vista computer? The compatible encryption for vista is WPA, sometime using WEP it is not working properly. So I might advise you to access the configuration of your router (192.168.1.1) and change the wireless settings of your router to WPA-Personal.

ENET Port issue on BEFW11S4 Wireless Router


Hi!

Try these steps:

1. Make sure the wireless is disabled when you're doing that. It might cause a confusion between the wired and wireless connection.
2. Try to plug it at other ports (1-4)
3. Try another known working ethernet or CAT-5 cable.
4. Set the laptop's LAN card's speed to 10-hald duplex.

Try these and hope it will help you ;-)

Linksys BEFW11S4-RM 4 port wireless router


This is an old router. Look at the power light. You must have a STEADY power light. RESET the BEFW11s4 by pushing the reset button for 30seconds. Unplug the power of the BEFW11s4 for 30 seconds. Connect pc to port 2 or 3. pc should get an ip of 192.168.1.x. If you are getting this ip that means that the pc is already detecting the router.

Linksys Wireless B BEFW11S4


That router should have a small hole on the back of the router (near the power plug, I believe) with a button inside. Use a paperclip to hold that button down for 5 to 10 seconds, then reset the power to the router, and it should be back to it's defaults.

If that doesn't work, the firmware is probably corrupted, and there's not a whole lot you can do about it.

Drivers 4 Linksys BEFW11S4 ver. 4


Your wired network adapter will talk to a wired router without a driver for the router on your computer. Your wireless adapter likewise will talk to your wireless router without a driver for the wireless router on your computer. Your wired and wireless adapters however do require drivers and the wireless adapter can require configuration. Please provide the manufacturer and model of your computer so I can learn about your wireless adapter and we can work to get it connected to the router.

Do you currently have your router connected to your internet service providers connection and do you have another wired or wireless computer successfully using this device to access the internet?
