Cannot setup WPA2 on WUSB54G & WPC11 adaptors

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.

Network Key (WEP, WPA, WPA2 Encryption key)To connectyour computer to a wireless router, you click the Refresh networklist, then Choose your wireless network and then click Connectto your secured Wireless Network, it will asks for a Network Keybefore allowing you to connect into your wireless network. This NetworkKey is either the WEP, or WPA or WPA2 Encryption key that is used toconfigure the Wireless Router. The Passphrase is an alternate way tosetup the Encryption key.
When you are requested for a Network Key, you can just enter the Passphrasethat was used to configure the Encryption key in the wireless router.http://www.fixya.com/support/r5270415-network_password_network_addressFor information on securing your wireless network,configuring the wireless router and configuring the wireless card in thelaptop/computer, please click on this link and follow my instructions :-http://www.fixya.com/support/r3559128-wireless_router_security

Theencryption key secures your data from unauthorized access. The router's password is a Passphrase or the WEP or WPA orWPA2 encryption key. The Passphrase generates the WEP or WPA or WPA2 encryptionkey and this is in the router's wireless settings. To connect to your wireless router, it needs the router'swireless settings configured ie SSID, WPA or WPA2 encryption key and also thewireless cards in all the laptops and or computers needs to be configured withthese router's wireless settings. Then the laptops and desktop computers can communicatewith your wireless router.

Most of the newer routers use a newer type of encryption (WPA or WPA2) which is not supported by older 802.11b hardware.

Either set the Linksys router to use WEP encryption, or get a newer 802.11g card for the old laptop which can use WPA or WPA2 encryption.

Older versions of Windows XP also need to be upgraded to Service Pack 3 or apply this patch:

The router's password is a Passphrase or the WEP or WPA orWPA2 encryption key. The Passphrase generates the WEP or WPA or WPA2 encryptionkey and this is in the router's wireless settings. To connect to your wireless router, it needs the router'swireless settings configured ie SSID, WPA or WPA2 encryption key and also thewireless cards in all the laptops and or computers needs to be configured withthese router's wireless settings. Then the laptops and desktop computers cancommunicate with your wireless router.

The WPA code is part of the wireless configuration, it is the WPA encryption setting (WPA2 is the latest and strongest encryption version).

To connect to your wireless router, it needs the router’s wireless settings configured and also needs the wireless cards in all the laptops and or computers to be configured with the router’s wireless settings. Then the laptops and desktop computers can communicate with your wireless router.

To set-up and secure the wireless router from unauthorized access, follow these steps: -
1. Connect the wireless router to your computer with a LAN cable.
2. Start your browser and enter the router's configuration URL IP address. (The Linksys configuration URL is http://192.168.1.1 )
The default login username is admin
The default password is admin
3. Enter the router setup, login and password
4. Change the admin password
5. Go to the wireless settings and change the default SSID and turn off SSID broadcast.
6. Setup encryption key the strongest is WPA2 (if not then WPA). The encryption key can be easily set up using a passphrase (it can be an alpha numeric phrase or words).
7. For further security measures - turn on MAC address filtering and enter the MAC address of the wireless cards on the computer/s you want to connect to this wireless router.
8. Record the settings you have made and keep it in a safe place and Save the settings.
9. Configure the wireless cards on the computer/s with the SSID and encryption settings of the router.
10. Remove the LAN cable between the router and the computer then the computers should be able to connect to the router wirelessly.
To access the Internet you need to connect the DSL or cable modem to the WAN (Internet) port on the wireless router.

You need to configure your router and use WPA encryption so that all accessing device can connect to it.


The obvious reason why the dell laptop can't connect is because of the WPA encryption set. It is different compared with what your router is actually broadcasting: WPA2.

So you can choose one of the 2 things to alter. Change your router's WPA2 encryption to WPA or change your Dell's setup to WPA2.

Particularly I think the problem is not in Wi-Fi connection for your laptop, but the configuration of your router, try using wpa security checks and only connection, besides if you give before you upgrade the service pack, the connection works properly. Additionally if you give before you upgrade the service pack, the connection works properly.

The problem is maybey your router is not compatible boot your pc into safe mode and do system restore to when you had the other service pack.
