I have been using my brand new core i7 27" iMac for the last week! And I have noticed a wifi bug that's driving me crazy!

 

Everytime my iMac goes to sleep when I wake it up the wifi won't detect any networks at all. It's just like if the wireless card is still sleeping! At first I waited for a while because I thought it would take longer to wake up! But it never detected any networks at all.

 

If I manually turn the wifi Off and then turn it back ON then  it detects my network and all the wireless networks around with any problem.

 

My home router is an Airport Extreme Dual Band !

 

Is anyone out there having the same issue?  or could it be that I got a faulty airport extreme card in my iMac??

iMac, Mac OS X (10.6.7)
