WPA-PSK wireless not accepting password
For some reason I can't seem to connect to one in particular wireless internet router- It is using WPA-PSK security, and airport is telling me that I have an incorrect password although I am positive it is the correct one. I friend of mine determined that the router's security settings should be allowing me in, that it is most likely my computer that is the bad link- Please offer any suggestions!
