WPA2 Setup?

    I'm new to wireless routers so please excuse my newbie question.

    I've just set up my WRT54GS and it is working fine. The problem is that it is using WEP. From what I've read, WPA2 is much more secure.

    For the life of me I can't get/find the option to change WEP to WPA2. HELP!

    i'm assuming you know to open a browser and go to 192.168.1.1 or whatever your router's ip is set to, after that, if its a WRT it's probably under wireless --> wireless security. change the encryption to wpa or wpa2 and pick, pick an encryption algorithm(TKIP or AES, AES is more secure), enter a password, and click save settings.

    Thanks for your reply. Yes, I have done the things you mentioned. When I do this my laptop can no longer find the wireless connection.

    I'm beginning to think that the wireless card in the laptop doesn't understand anything except WEP. (Dell B130)

    This may be the case. However, if you are using Windows XP to connect, I believe it only supports WEP and your laptop's card may support other modes. I know the broadcom card in my laptop only supports upto WPA(PSK).

    To get the WPA, I had to use the Broadcom Wireless Uitility for my laptop's network card and let it do the connecting. You may want to goto Dell's site and look up your machine and see if you can find drivers/wireless utility for your laptop's network card.

    your wireless devices ALL need to be WPA2 compatable, if there is no option then you either cannot use WPA2 on the currect wireless device on your laptop or the drivers and WinXP dont yet support WPA2.

    http://support.microsoft.com/?id=893357 give syour WInXP SP" WPA2 access, but your wireless device may also need new drivers (if there are any. if not get a new wireless card for the laptop that supports WPA2.

    Setup depends on your firmware also. With dd-wrt v23 I selected WPA2-PSK- Mixed for security, TKIP+AES for encryption, and computers can connect at the highest security level they support. I have simultaneous connections with WPA2-AES, WPA-AES, and WPA-TKIP, depending on what the various wireless NICs support. To support WPA2 with the referenced Microsoft SP2 upgrade, the newer cards (Intel B&G, Linksys USB) didn't need new drivers, the older cards (Agere, D-Link, Belkin) don't seem to have them.

    Well, I've tried all the things mentioned here and nothing has worked. I did update the Dell wireless card drivers software and install the XP patch for WPA2. After this the computer never again was able to log onto the router. It would see the network, but couldn't access it.

    I even did a hard reset on the router and tried a clean install. Again the computer saw the network but couldn't connect to it

    I finally did another hard reset of the router and it went back to WEP. I then restored the computer back to a point before I updated the drivers and things are back to normal .

    At this point I have to think that there's a problem with Dell's drivers or wireless card with anything more than WEP!

    Someone please prove me wrong.

    Are you using the XP WZC service to control your card? When you "View available wireless networks", it should indicate WPA (or WPA2) for your router if WPA is enabled and the card is WPA capable, and when you try to connect should show a WPA dialog for entering a passphrase. If your card is not WPA capable, I would suggest a USB card like the Linksys WUSB54G as a simple solution. What type of card does Dell use? There are also sometimes OEM upgrades to the drivers that extend the capabilities but are not supported by Dell.

    I'm not sure what all the fuss is about for WPA2 for home usage.

    WPA with AES encryption and a long random key is plenty strong enough. People are generally using PSK (Pre-Shared Keys) not any of the fancy enterprise functions of WPA2 anyhow.

    Best thing you can do is find the "random key generator" site and make a 63-character WPA key, and just use that.
