I have recently added a WPA2 password to my home network incorporating 2 G5's, Airport Express and an XP box.
No problems for the G5's but I can't get the XP box to join the network.
Can someone please outline the steps I need to take.
Thank you.

is your pc's wifi card wpa compatible?

How would I be able to check?
Thank you.

Windows will be trying to connect using the old config. you will need to delete this wireless set-up, and add it back with the new security settings.

Sorry I can't elaborate more, but it's the sort of thing I can find when in front of a PC (something I try to avoid) but can't tell you where to find.

Disko's question is the important to get checked - but just to clarify, is it WPA2 you have setup, or just WPA?

I run an ADSL modem to an Airport Express, which I have connected via WPA to my PowerBook - when my friends come over with their DELL Notebooks etc running XP, they can then connect to the web wirelessly with my password entered.

If the Windows machine has a card capable of using WPA security, then they should work.

YES. Definitely worth a shot.

Just start from scratch with the PC - ditch the old network connection/access setup and setup with the new details.

@back2mac

yeh change your setup from WPA2 to WPA and it'll most likely work.

My Netgear g wireless nic works fine with WPA ...

I believe there is an XP update for WPA2.

Make sure you have this as well as Service Pack 2 installed.

WPA2 implements the mandatory elements of 802.11i.

Official support for WPA2 in Microsoft Windows XP was rolled out on the 1st of May 2005. Driver upgrades for network cards may be required.

Apple Computer supports WPA2 on all AirPort Extreme-enabled Macintoshes, the AirPort Extreme Base Station, and the AirPort Express. Firmware upgrades needed are included in AirPort 4.2, released July 14, 2005.

Someone mentioned to me today that XP can't join a wireless network using WPA-PSK unless the SSID is being broadcast. Are you broadcasting the SSID?

Thank you to all who offered help.
My card wasn't WPA2 compatible. I just changed to WEP for the time being - and everything works fine.

Thank you again.

Your card may not be WPA'2' compatible, but it may be WPA compatible.. There's a difference.

Best to check as WPA is more secure than WEP and most people in the know would probably recommend having that rather than WEP.

WPA2, as I understand it, is mainly used in corporate environments to secure office networks that carry sensitive info and/or are prone to wireless hacking from outsiders.

I don't broadcast my SSID and although my Wintendo has trouble connecting some of the time. I usually find tha I have to "Disable" the card, then enable it and it connects.

Ironic that I have no issues with the car in box OS X and more ironically, my Linux box.

please note that WEP is insecure ... the WEP key is broadcasted and can be picked up if someone sniffs the "air" ...

Yeah, last time I checked it took something like 8 minutes to crack WEP. Scary that people still use it.

Reminds me of the place I used to live at. Paid approx $2000 for a wireless network, you would think it would be secure. This companies idea of security was using WEP and suppressing the SSID (if we suppress it they wont know it's there :blink , certainly got our monies worth (at least I didn't pay for it)
