Hello, I have an airport base station. I have 3 macs and 3 iphones. My Macbook pro is right by the airport base station and my other two macs are downstairs. Forsome reason my airport is acting up. The computers downstairs can not connect. It would should that there is a wireless conneciton but when i click to connect it would ask for password. After i enter the correct password it says invalid password. So after i do that i take the same computer upstairs right by the airport it would connect. Then i go back downstairs it would work but after i put computer in standby and turn it back on it has same problem. All my computers and iphones are doing this! help!
