Primeiro, sugiro que você desligue a economia de energia no Network Manager. Do terminal:

sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Em seguida, eu li este post: link

% bl0ck_qu0te%

Assim, verifique as configurações no roteador. WPA2-AES é preferido; não qualquer modo misto WPA e WPA2 e certamente não TKIP. Segundo, se o seu roteador for capaz de atingir N velocidades, você poderá ter melhor conectividade com uma largura de canal de 20 MHz na banda de 2,4 GHz, em vez de 20/40 MHz automática, embora seja provável que afete a velocidade N.

Reinicie o computador e o roteador e deixe-nos ouvir seu relatório.
