I upgraded my Acer 9301 laptop from Fedora 16 to Fedora 17. Now I can't enable wireless networks in KDE. When I boot, the LED for WLAN is lit, which indicates that it is enabled. However, KDE NetworkManager says that the WLAN Interface is Unavailable.
ifconfig shows interface eth0, but it is not UP.
I have attached lines from dmesg relating to ath0 or ACPI in the attachment.
This is my chip:
[2012-04-27 18:09:06] ath5k phy0: Atheros AR2413 chip found (MAC: 0x78, PHY: 0x45)
When I try to enable wireless, I get:
[2012-04-27 18:14:28] ACPI: EC: GPE storm detected, transactions will use polling mode
[2012-04-27 18:15:16] ADDRCONF(NETDEV_UP): ath0: link is not ready
And when I push the WLAN button, I get:
[2012-04-26 23:54:25] ADDRCONF(NETDEV_UP): ath0: link is not ready
[2012-04-26 23:54:48] ACPI Error: [CB04] Namespace lookup failure, AE_ALREADY_EXISTS (20120111/dsfield-143)

I have these versions:
