Answer 1

Você tem dois drivers carregados que provavelmente estão em conflito.

É um pouco incomum, mas esse é um dos poucos exemplos de dois drivers diferentes que reivindicam o mesmo dispositivo e, provavelmente, estão em conflito. Vou sugerir que você inclua uma lista negra e veja se a rede sem fio começa a funcionar.

É um pouco de adivinhação para ver qual funciona, e talvez funcione melhor. Vamos tentar primeiro:

sudo -i
echo "blacklist rtl8192se"  >>  /etc/modprobe.d/blacklist.conf
exit

Reinicie e informe se o sistema sem fio está funcionando.
