http://ubuntuforums.org – Hi, i upgraded ubuntu from 11.04 to 11.10 and wifi is not working anymore. my pc is connected to a router. Now Internet is working just with ethernet. i've got a Atheros card. on the menu bar on the top, the wifi icon disappeared. and the wifi connection disappeared as well. in "additional driver" the list is empty. this is the result for ifconfig: Code: marconicole@desktop:~$ ifconfig eth0      Link encap:Ethernet  HWaddr e0:cb:4e:c7:9e:74            indirizzo inet:  Bcast:  Maschera:255.255.
