My PC doesn't have a wireless card and I'm trying to connect my N900 to my PC with USB, and access an unencrypted wireless network.

The N900 is connected to the wireless network, and then using Nokia Ovi Suite 3.0.0.290 I try to use the "Connect to internet" feature. I choose "I want to define the connection settings manually" option, then the next screen wants the name of the access point, a user name, and a password. I have entered the name of the access point to no avail, I've also tried using "guest" as the user name and password. however this is an unsecured wireless network so I don't know what user name and password even mean in that context.

Thanks for reading.
