É o seguinte galera, eu usava o Ubuntu 12.10 e funcionava normalmente, porém agora tenho obrigatóriamente que trabalhar com o Ubuntu 10.04, instalei ele dual boot junto com o windows 7, só que meu wifi não pega de jeito nenhum, nem aparecem as redes. já ví vários tópicos aki porém nenhum se encaixou no meu problema.
já tentei coisas como:
root@ubuntu:/home/luan# iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
ppp0 no wireless extensions.
----------------------------------------
ou como isso que não acontece nada:
root@ubuntu:/home/luan# lspci -k |grep -i wireless -A 2
root@ubuntu:/home/luan#

isso tbem:
root@ubuntu:/home/luan# ifconfig
