I am running a Linksys Wireless Router WMP11 to two computers at seperate locations, and having the router at another location. One computer has already been setup and is currently working. The one already setup is using a USB wireless adapter along with wireless card, but the one not connected is using a Dell Truemobile 1300 USB Wireless Adapter. This one however requires a WEP/WPA key that has been already inputted for the connection. The WEP/WPA key that I located in the linksys properties is exactly 8 characters long. Where can I find the WEP/WPA key? If I am unable to find it, could I just reset the password at the already setup computer?

That's the passcode: It generates the encryption key if you're too lazy/typing challenged to type in the encryption key.

If you're using WEP (a) don't and (b) the passcode may not work between different vendors' products; you'd need to enter the encryption key directly on both sides. WPA doesn't suffer from this problem however these days securing a network with an 8-character passcode is only slightly more secure than hiding the key under the doormat.

O.k. I need to find the passcode or encryption key for WPA. Where might I locate it in?
