When you go to your Sinksys configuration utility, it will either give you option to select security mode in which you can put a pass key by WEP or other option.

    Appendix B: Wireless Security

    Linksys wants to make wireless networking as safe and easy for you as possible. The current generation of
    Linksys products provide several network security features, but they require specific action on your part for
    implementation. So, keep the following in mind whenever you are setting up or using your wireless network.
    Security Precautions
    The following is a complete list of security precautions to take (as shown in this User Guide) (at least steps 1
    through 5 should be followed):
    1. Change the default SSID.
    2. Disable SSID Broadcast.
    3. Change the default password for the Administrator account.
    4. Enable MAC Address Filtering.
    5. Change the SSID periodically.
    6. Use the highest encryption algorithm possible. Use WPA if it is available. Please note that this may reduce
    your network performance.
    7. Change the WEP encryption keys periodically.
    To ensure network security, steps one through five should be followed, at least.
    Security Threats Facing Wireless Networks
    Wireless networks are easy to find. Hackers know that in order to join a wireless network, wireless networking
    products first listen for “beacon messages”. These messages can be easily decrypted and contain much of the
    network’s information, such as the network’s SSID (Service Set Identifier). Here are the steps you can take:
    Change the administrator’s password regularly. With every wireless networking device you use, keep in
    mind that network settings (SSID, WEP keys, etc.) are stored in its firmware. Your network administrator is the
    only person who can change network settings. If a hacker gets a hold of the administrator’s password, he, too,
    can change those settings. So, make it harder for a hacker to get that information. Change the administrator’s

    SSID. There are several things to keep in mind about the SSID:
    1. Disable Broadcast
    2. Make it unique
    3. Change it often
    Most wireless networking devices will give you the option of broadcasting the SSID. While this option may be
    more convenient, it allows anyone to log into your wireless network. This includes hackers. So, don’t broadcast
    the SSID.
    Wireless networking products come with a default SSID set by the factory. (The Linksys default SSID is “linksys”.)
    Hackers know these defaults and can check these against your network. Change your SSID to something unique
    and not something related to your company or the networking products you use.
    Change your SSID regularly so that any hackers who have gained access to your wireless network will have to
    start from the beginning in trying to break in.
    MAC Addresses. Enable MAC Address filtering. MAC Address filtering will allow you to provide access to only
    those wireless nodes with certain MAC Addresses. This makes it harder for a hacker to access your network with
    a random MAC Address.
    WEP Encryption. Wired Equivalent Privacy (WEP) is often looked upon as a cure-all for wireless security
    concerns. This is overstating WEP’s ability. Again, this can only provide enough security to make a hacker’s job
    more difficult.
    There are several ways that WEP can be maximized:
    1. Use the highest level of encryption possible
    2. Use “Shared Key” authentication
    3. Change your WEP key regularly
    WPA. Wi-Fi Protected Access (WPA) is the newest and best available standard in Wi-Fi security. Four modes are
    available: WPA-Personal, WPA2-Personal, WPA-Enterprise, and RADIUS. WPA-Personal gives you a choice of two
    encryption methods: TKIP (Temporal Key Integrity Protocol), which utilizes a stronger encryption method and
    incorporates Message Integrity Code (MIC) to provide protection against hackers, and AES (Advanced Encryption
    Standard), which utilizes a symmetric 128-Bit block data encryption. WPA2-Personal only uses AES encryption,
    which is stronger than TKIP. WPA-Enterprise offers two encryption methods, TKIP and AES, with dynamic
    encryption keys. RADIUS (Remote Authentication Dial-In User Service) utilizes a RADIUS server for authentication.

  • Edgar Allan Pagayona
    Edgar Allan Pagayona May 01, 2008

    WPA-Personal. If you do not have a RADIUS server, select the type of algorithm you want to use, TKIP or AES,
    and enter a password in the Passphrase field of 8-63 characters.
    WPA2-Personal. Enter a password in the Passphrase field of 8-63 characters.
    WPA-Enterprise. WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS
    server is connected to the Router or other device.) WPA-Enterprise offers two encryption methods, TKIP and
    AES, with dynamic encryption keys. Enter the RADIUS server’s IP Address and port number, along with a key
    shared between the device and the server. Last, enter a Group Key Renewal period, which instructs the device
    how often it should change the encryption keys.
    RADIUS. WEP used in coordination with a RADIUS server. (This should only be used when a RADIUS server is
    connected to the Router or other device.) First, enter the RADIUS server’s IP Address and port number, along
    with a key shared between the device and the server. Then, select a WEP key and a level of WEP encryption,
    and either generate a WEP key through the Passphrase or enter the WEP key manually.
    Implementing encryption may have a negative impact on your network’s performance, but if you are transmitting
    sensitive data over your network, encryption should be used.
    These security recommendations should help keep your mind at ease while you are enjoying the most flexible
    and convenient technology Linksys has to offer.

I have broadband with a wireless router but it wont connect without an ethernet cable, I cannot seem to find a wifi driver on the pc to enable me to use my wireless router


As you have mentioned that you have a desktop PC . So you need a wifi lan card to access the wireless router. Then you can access the internet through your wifi router. You can buy a wifi lan card for the same and go for Netgear GA311 for the same. Hopefully it will help you.

Wireless Internet router (home) Security


Unsecured means that you have not set any passwords or keys to lock your wireless connection. This is not a good practice. And yes, if the connection is unsecured, then others will be able to use it without any problems.

Do this if you are comfortable:

1) Go to Internet Explorer
2) Type http://192.168.1.1 (If that does not work, then try http://192.168.1.254)
3) Type the Username and password (both "admin")
4) Look for a Wireless tab
5) Look for Security and then look for WEP encryption.
6) Enable 64-Bit WEP encryption and type a key there. Save the settings.
7) Now when you try to connect to your connection, it will ask you for a key, put the same key as you had put in the router.

Please keep in mind to wire your laptop before doing these steps. Otherwise, you may be disconnected.

I've installed my wireless router, modelwrt54g2v1, and the yellow ethernet cable is still connected to my laptop, once I remove it I have no connection?


The yellow cable (CAT5) is giving you your internet connection
you will need to follow some steps:
1) Access the routers GUI (usualy by going to a web-page in your Internet explorer EG 192.168.0.1 check the manual)
2) make sure that wireless is enabled on the router + DHCP is enabled
3) at this stage set wireless security here as well (to stop unwanted use of your broadband and people hacking your PC)
4) make sure that the laptop wireless is switched on, sometimes there is both a physical on/off switch and a software/keyboard enable/disable button, disconnect the Yellow network cable
5) go to control panel:network connections
6) right click on the wireless connections icon and then view available wireless networks
7) if you see your network then highlight it and click connect
8) enter the security password (if any) which you set in step3 above.

let me know how you get on

the blue and jellow ethernet cord is the same thing.
Make sure you have wireless switch on (enabled) on the laptop
If you have wireless enabled, it should say one or more wireless networks detected in windows xp. Also, if you have a certain router, you might need a code to unlock it so you can use it.

I have a wireless g broadband router i am connected on the main computer but my wireless computer says connected but i cant go to any web pages


Is the problem that "nothing coming from the modem to the router"
if the router has more than one Lan port try the cable from the modem to the router, in the first lan port or the last port.

if its a wireless problem,ensure wireless router function is turned on ,and the adapter is enabled on the pc ,

if you set up a security key in the router ensure that it is put into the other pc wireless setting.(but try setting up without any security keys) when succesfull you can ad the security measures.


sometimes you need to turn on the modem first then turn the router on after a little while to sort the ip address out before trying to connect the other pc, in the first instance.

hope this is of help

please rate my efforts as this is our reward

good luck
