iMAC 21" WIFI failing after 10.7.4 update
Hi,
Before the 10.7.4 update the WIFI connection from the iMac 21.5" to the airport extreme router works fine!
Now it's failing several times a day! it looses the wifi connection and you are unable to see any wireless accesspoints or SSID's
Macbook pro, iphone & ipad + PC's still works fine!
The only way to get the wireless up and working again is to shutdown and restart the iMac.
Please help, there must be a serious bug in this update any solution available to solve it?
In the log i can see alot, don't know if this is some clue or error occuring just after the wireless connection is dropped for unknown reasons.
"kernel: 2329.723808: ath_chan_set: unable to reset cannel XX (XX00Mhz) flags 0x10080 hal status 17"
"kernel: 2632.354892: ASSERT: Can not reenter VAP State Machine"
"kernel: AirPort: Link Down on en1. Reason 8 (Disassociated because station leaving)."
Turning off and on the wireless interface only shows the following in the log, and the wifi will not see any SSID's :
"kernel: 71847.200440: switchVap from 1 to 1"
