hello everyone, I can not say that I'm a (french) expert on linux but since I played a lot with several distrib, I understand quite well the system and I have a little probleme with the madwifi drivers. Something strange but I think I have made a mistake somewhere. here's what I've done so far : - update ubuntu - played with settings (don't remember what I've done exactly, SSD, disable services... :roll: ) - disable atheros drivers and support - follow the guide to install the current madwifi drivers (everything seems to do what it should) - modprobe ath_pci - edit etc/modules and then ..... nothing. No wifi interface :? . - I tried my usb wifi stick and everything work fine with it. Then I removed linux-restricted-modules to delete atheros drivers and follow the guide again but nothing comes up. ifconfig shows lo, eth0 and eth0:avahi. Seems like the wifi card takes some holidays :mrgreen: . I made the little change in rc.local et sysctl to see the wifi led and manage the wifi switch but I didn't see any change. I think I'm missing something. Could anyone help me with this before I try ndiswrapper ?
