Wi-fi desabilitado por hardware, Ubuntu 13.04, HP Mini 100e

[rafonsosilva]

Caros,
Possuo um HP Mini 100e (netbook) e há uma semana atualizei o ubuntu da versão 10.04 LTS para a 13.04.
Após a atualização, o wi-fi aparece como "desabilitado por hardware", mesmo quando o led do teclado indica que o wi-fi está ativado.
Segue resultado do rfkill list wlan
0: phy0: Wireless LAN
   Soft blocked: no
   Hard blocked: no
1: hp-wifi: Wireless LAN
   Soft blocked: no
   Hard blocked: yes

Mesmo após tentar os comandos abaixo, continua sem funcionar.
rfkill unblock wlan
rfkill unblock all
sudo service network-manager restart

Também tentei outro comando que encontrei em um blog (sudo rfkill unlock hp-wifi), porém o terminal respondeu conforme abaixo e o wifi de meu computador continua sem funcionar:
Usage: rfkill [options] command
Options:
–version show version (0.4-2ubuntu1 (Ubuntu))
Commands:
help
event
list [IDENTIFIER]
block IDENTIFIER
unblock IDENTIFIER
where IDENTIFIER is the index no. of an rfkill switch or one of:
all wifi wlan bluetooth uwb ultrawideband wimax wwan gps fm

Agradeço desde já, se alguém puder me ajudar.

Acho que seu problema é de firmware. Você tem como se conectar à internet por cabo?

[rafonsosilva]

Olá, zekkerj.
Sim, consigo conectar normalmente por cabo.
Pesquisando um pouco mais em outros sites e blogs vi muitas pessoas com problemas parecidos e as soluções indicadas por outros usuários era a instalação do driver da placa wireless.
No meu caso, cheguei a baixar um arquivo do site da Realtek para a placa RTL8191SEvA Wireless LAN Controller para fazer o teste, porém o arquivo tem extensão tar.gz (rtl8192se_linux_2.6.0019.1207.2010.tar.gz) e não faço a mínima ideia de como instalar para testar e ver se realmente é este o problema.

Você conseguiria me ajudar com isso?

[zekkerj]

Primeiro tente atualizar o sistema, a partir da conexão por cabo.

sudo apt-get update && sudo apt-get dist-upgrade
