I want to re-enter my security key no as i had to replace my laptop

Hi
You say that the radio keeps demanding the WEP key for your WiFi connection. WEP is just one of several security types to be used for WiFi. The fact that the radio is asking for a WEP key indicates to me that your WiFi is more than likely set to one of the other security standards such as WPA, WPA2-PSK etc etc etc. If this is the case your laptop and kindle etc will be using the same security standard as your WiFi router. To find out which security standard is being used in Windows 7, on your laptop, click on the active connection in the system tray to bring up the list of available connections and then click on "Open Network and Sharing Centre". When the Network Centre page comes up double click on the "Wireless Connection".
A status box will come up and about half way down is a utton "Wireless Properties". Click on this, and in the box that comes up click on the security tab and it will tell you the security type, the encryption type and the wireless key (click on "Show characters").
If the encryption type is not WEP then the radio will not connect to your WiFi, and the radio settings for Security and encryption need to be set to the same as on the laptop for it to connect.
Hope this is helpful, if so would you please register that with Fixya
Cheers

if you enter into the configuration mode of your linksys,go to wireless and in security the section for enter the passphrase or key is what your router is asking for.copy that and use it.

Network security key
Some later model wireless routers have the Password (ie.Encryption key) and the SSID already configured in the wireless router and this information is printed on a label on the bottom of the router.
These settings can be used to configure the wireless card and wireless adapters in your computer/laptop.
If these settings do not suit you, then it can be changed to suit your requirements.
The encryption key secures your data and wireless connection from unauthorized access.To configure the wireless settings in the router, connect a LAN cable from your computer to the wireless router, then open a Browser on your computer and enter the router's configuration IP address, then enter the admin login and password and then go to the wireless settings and configure the SSID and Encryption key.
The router's encryption key can be a Passphrase or the WEP or WPA or WPA2 key.If you use the Passphrase method select either WEP or WPA or WPA2 to generate the encryption key. You can enter the WEP or WPA or WPA2 key with 8 to 63 ASCII characters or 64 Hex digits.
Most people use Passphrase which is easier to remember eg. I was born in January 1988.
The strongest and latest security is WPA2, the weakest and oldest is WEP. To connect to your wireless router from the computer/laptop, configure the wireless card in your computer/laptop with the router's wireless settings ie SSID, plus the WPA or WPA2 encryption key. Then computer/laptops can communicate with your wireless router.

Welcome to Fixya

First you need to check is if the WEP key that you are entering is the WEP key of your router. Try to connect a laptop to your computer which do not belong to the network. Say, your friends laptop. This laptop will ask for a security key if it's the first time to connect to the network. Enter your security key and see if the laptop can connect to the network. If it did not connect then the problem is your WEP key.

Have a good one!

1. open internet explorer on your main computer and type 192.168.2.1 in the top address bar and press Enter.
2. click on Login in the top right corner.
3. Leave the password blank and just click on submit.
4. now click on Security under Wireless on the left.

On this page you will find a wpa or wep key that the security key, so you can enter the same key on the laptop and it will connect to the wireless network.

Hello Friend,
Its beacuse of incorrect security. Try loging on to your router and re-enter WEP/WPA....Security key. Someone else might have changed the security key without your knowledge.
Good Luck!

an access key is configured in the wireless routers web console to allow only the users with the key to connect to it. sometimes referred to as a "WEP KEY" or "WPA key" or "authentication code" To login to your web console, join your computer to your wireless router with a network cable (yellow below) to an Ethernet port 1,2,3 or 4 open your browser and surf to (instead of www) 192.168.1.1 or 192.168.0.1 (most common) you should presented with a login screen most common username and password is admin and admin once you have logged in look for your wireless security setup screen such as this.....
look for the Wireless and Security Screens to enter or check your access security code, enter a code or review the existing one. Then once you save your changes you can connect with your laptop, now that you know the security key.

Sometimes the key length would change for security purposes. What you have to make sure is that you are entering the correct network key.
Use a connected computer like your roommates laptop or hardwired connect you laptop to the router using an ethernet cable to access the setup page of the router.

In your browser's address bar, type 192.168.1.1. By default, leave the username blank, password is admin.
Go to Wireless -> Wireless security.
You will see the network key. Just copy that and enter it on your laptop.
I hope this helps!
