Q: On the same iMac wifi can be connected in Win7 but not OSX Maverick

Hi All,

I'm encountering a problem of connecting to wifi on my new iMac. I'm wondering whether anyone in the community has also encountered the same problem.

My iMac is a late 2013 model with 21.7" display bought just 2 weeks again. The OSX installed is Maverick with the latest update. I have also installed Win7 using Bootcamp.

At the beginning, the wifi connection was OK both in OSX and Win7. However, just around 1 week ago, the network connection began to fail in OSX. When logging into the Win7, I can still connect to my router through the wifi and everything is OK. This at least can proves that the wireless adapter in the iMac itself doesn't malfunction and the router works fine. Also all the other devices in my home connects to the same router through wifi has no problem including 2 iPhone5, 1 iPhone4S, 1 iPhone4 and a MBA 2012 model.

However, whenever I switched to the OSX any try to connect to the wifi ends in a failure. The SSID of the network is displayed in the visible network list still but not connectable. By clicking the name and after a while for the iMac to try to connect, a message saying "network cannot be joined" will pop up. Even by running the network diagnosis and specifying a static ip address for the iMac won't help. And I have also tried out some tricks in the community but all seemed not work.

Really appreciate if someone can suggest and help.
