Olá, recentemente eu instalei o LMDE 4, e quando eu tento me conectar à uma rede sem fio, recebo duas mensagens de erro. Já tentei resolver esse problema de diversas maneiras, mas sem sucesso. Como eu posso resolver esse erro?

Placa de Rede: Realtek RTL8723B.

Sim, ele "enxerga" todas as redes wi-fi disponíveis, mas quando eu tento me conectar à minha rede, recebo as duas mensagens de erro.
