Having issues with OS Lion and Wifi
Last year I converted after many years of being a Windows follower. I have recently updated my Mac Pro (Mid 2010) to Lion and now have found my wifi doesn't work. I am connected via an Airport Extreme. I did have to replace my wifi card after just two weeks of use. The people at the Apple store told it was Defective! I have updated everything in my house to ensure it is compatible with my new system. All of my other devices iOS and PC etc. work perfect. I am just not able to connect via wifi. I have followed many of the different suggestions can anyone please advise?
Thanks
Mac Pro, Mac OS X (10.7.3)
