Q. My MBA keeps dropping wifi connections, especially when coming up from sleep… it is weird because it prompts me to reenter my WPA2 password every time it does this but even after entering the password it can’t connect! Can you help?
A. I have a MBA that exhibited similar issues, so far the best help has been the latest Lion update (10.7.1) Hopefully this update will help you too and get your MacBook Air working well with wifi! If you still encounter problems, please let me know and also include your wireless router/access-point model # for troubleshooting purposes.
Also, here is an article about the surprising fact that you use “Software Update” instead of the “App Store” to obtain the update…
