Airport turns off
Since upgrading Airport to its latest version I have not been able to keep Airport connected for long periods of time. This morning things got worse, even after resetting the PRAM which usually helps to engage it for some time, it stayed connected only for a matter of minutes. I am running 10.7.5 on a 17 inch MacBook Pro 4,1, which otherwise is very reliable. I have also reset the SMC as a part of this process of trying to correct this glitch. All help will be appreciated. Thanks, Thomas
