Problemas de conexão

[AllanCic]

 Dae galera, então, ante-ontem usei a net no meu pc normalmente, ontem quando cheguei em casa e liguei o pc, a net não funcionava mais, no note do meu irmão ela continua funcionando, porém, pra mim, nem wireless, nem lan, tentei de tudo que foi possivel achar no google, desativei/reativei placa na bios, resetei roteador, tentei o comando ifconfig wlan0 up, e nada, o pc acha a rede wifi, e aparece conectando, mas não conecta, alguém tem mais alguma ideia do que posso fazer? O roteador não é, já que funciona no note, consequentemente, os cabos também não, a placa não deve ser também, ideias? T_T

Mesmo funcionando no note, pode haver algum problema no roteador que impeça sua máquina de funcionar.
Desligue o roteador e ligue novamente; se depois disso o problema continuar, volte aqui pra gente analisar sua máquina.

 Então cara, eu já restei ele, mas o problema persiste, a internet funciona no note, mas não funciona nem no meu desk nem no meu vídeo game, quando tento conectar com o videeo-gamee na parte "wireless" do gerenciamento do roteador, em estatísticas, e diz que tem dois dispositivos conectados, mas o video-game não conecta, já tirei a segurança pra testar se era incompativel, mas nada, o único dispositivo que funciona é o note...
