Arrgh! I moved a week ago, and just got around to setting up my desktop computer - a 2.53 GHz mini (bought Jan 2010). I discovered that my ethernet cable got left behind in the move, and it is refusing to connect to wireless! My iPad 2 and Powerbook G4 are having no problems at all with the wireless, nor did my husband's MBA when he used it a few days ago. But when the mini tries to connect, it keeps giving a Connection Timeout - or, occasionally, an Invalid Password, even though I've triple-checked that the password is correct and the same one I'm using successfully on the laptop and iPad. I'm using a Medialink wireless router with a Westell DSL modem provided by Cincinnati Bell. I've reset both the router and the modem, with no change in any computer's ability to connect. I have run out of ideas! Any suggestions?
