Wireless Connection error

[StormyStan]

We are having an error connecting to our robot using wireless. It works perfectly fine when we are tethered in. But when we try to connect using wireless we get an error saying "Windows was unable to connect to 5175." I have looked everywhere and I cannot find an explanation why only the computer with code cannot connect wirelessly. Another thing to note is that the D'Link is listed as "Unidentified network" when we are tethered in if that is an issue.
