Having same problem, but here is more information that may help to solve this issue.
The Atheros AR5212 wireless chipset worked fine up through 8.10; did not seem to work for me in 9.04. Located at the bottom of this comment is the output from the lshw command. After much searching and experimenting, I found drpjkurian's post on the Ubuntu forums to be a solution to the problem: http://ubuntuforums.org/showthread.php?p=8255018#post8255018 However, neither the network-manager or Wicd allow me to access wireless networks. I have to use the command line to scan for networks as well as select the network. Please please please fix this so that the AR5212 works normally again upon regular installation. Thank you! Below is the lshw output. --------------------------------------------------------------- id: network description: Wireless interface product: AR5212 802.11abg NIC vendor: Atheros Communications Inc. physical id: 0 bus info: p...@0000:03:00.0 logical name: wmaster0 version: 01 serial: 00:19:7e:0b:94:eb width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix bus_master cap_list logical ethernet physical wireless configuration: broadcast = yes driver = ath5k latency = 0 multicast = yes wireless = IEEE 802.11abg resources: irq : 17 memory : edf00000-edf0ffff -- Wireless network not working after upgrade from 9.04 to 9.10 though wired network great.
