I have a 21.5" Mid 2011 iMac running 10.7.5
About a month ago my WiFi started dropping sporadically. It seemed to happen after being asleep. Since then the problem has gradually gotten worse, and it now stops working every time the computer is put to sleep, and even stops working while it's awake.
If I go open System Preferences --> Network, it shows the WiFi as being connected (green) even when it's not working.
The only thing I can do to get it to work again is click on "Turn WiFi Off", and then turn it back on, or restart the system.
I've searched endless discussions on various forums and nothing seems to resolve the problem.
I should point out that our dlink router is pretty new and all the other devices (phones, computers, PS3) don't have any issues.
It's driving me crazy.... please help.
