[kubuntu] Atheros wireless not detected

view full story

http://ubuntuforums.org – Hi, I bought a Samsung N310 laptop recently and loaded it with Karmic. My problem now is that my wifi adaptor can't be detected. I know that the N310 comes with an Atheros wireless chip, but I can't, for the life of me, find out which specific chip model it is. I know about the blacklist workarounds and have tried it but to no avail. I'm about to try compiling the latest madwifi drivers but before that, I found out something that's weird. If I remember correctly, even if a device can't be detected, I should still at least be able to pick up an unknown device in /var/log/messages or dmesg. But here, I don't seem to be getting anything. According to http://madwifi.org/, I should be able to see something along the lines of: Code: lspci | grep Ethernet 00:13.0 Ethernet controller: Unknown device 168c:0012 (rev 01) But I don't see that either. So right now, I'm worried that somehow, my wifi device has been turned off, like a hardware switch that turns it off. Problem is, the laptop does not have a dedicated on/off switch for wireless. If I'm running Windows, there's a Fn key to turn it on but when I try that under Ubuntu, I get this in /var/log/messages: Code: Nov  4 20:49:03 shortstop kernel: [  885.098515] atkbd.c: Unknown key pressed (translated set 2, code 0x86 on isa0060/serio0). Nov  4 20:49:03 shortstop kernel: [  885.098532] atkbd.c: Use 'setkeycodes e006 <keycode>' to make it known. I'd like to confirm first whether I'm supposed to get at least an unknown device notification in dmesg or /var/log/messages output if I lack a driver for my Atheros chip. Hope that someone can help.
