Did you setup encryption on the wireless signal?  If so, you will need to supply that password to the wireless utility when connecting.  I would suggest you use the Windows Utility to connect and not a third party application.

If the access
point only accepts WPA connections, and it wants a key of under 64
characters in length, and it doesn't support Windows Connect Now ...
you can't connect automatically. Instead, you have to enter the WPA key
manually: When running the aforementioned Wizard, there's an option to
"Manually assign a network key" that you have to pick. It seems that
selecting WPA causes the Wizard to create a 64-character encryption
key; it isn't uncommon for older access points to only want a
63-character (or shorter, like 50 characters in this case) key, which
makes the Wizard barf. Entering the key manually lets you respect the
access point's limit. The trick with Windows Connect Now is that part
of the standard specifies a 64-character key, so devices supporting
Connect Now will accept a 64-character key.

Hi,

Thanks for the info I will try that tonight, I do have security setup, (64 Bit) I have been asked for the passkey when connecting to the wireless but it does not accept it..

Will try later. I will also read all the links you pasted.

Again,

Thanks for your time and help...will let you know..

Use WPA or WPA-PSK and not the 64 bit key.
