I've found this question asked many times, but no definitive answers. I have a full-strength open wireless network. I have three wireless devices connected to it. I also have a Windows 7 computer that will show the network as a full-strength open network broadcasting its SSID. However, when I try to connect, it immediately says it can't connect to the network. Troubleshooter says "can't connect to hidden network" although it is not a hidden network and it's SSID is being broadcast. I have tried all of the suggested troubleshooting options to no avail. My networking knowledge is limited. I am wondering if the MAC address is being blocked? Any suggestions?
