Hello, My Sony Vaio VPC-Y11S1E notebook has an Atheros AR9285 chip, which is supported just fine by ath9k. The notebook also has a physical radio kill switch at the front that can be slid into one of two positions. Alas, the rfkill tool shows wlan0 as "hard blocked: yes" for either switch position. Consequently, txpower is off, and wireless networking cannot be activated. Could you kindly indicate which part of the kernel would be responsible for handling the radio kill switches -- cfg80211, ath9k, sony-laptop, ...? Are there any known fixes or workarounds? I'm using Kubuntu 9.10 with their stock kernel 2.6.31 and the wireless backports modules right now, but tests with Kubuntu 10.4 Beta and 2.6.32 failed as well. (Note that I cannot get ndiswrapper to work either, although it seems to power on the wireless card.)
