Faça:

gksudo gedit /etc/pm/power.d/wireless

você provavelmente terá que instalar o su:

(this will create or edit a configuration file that will override the default power management behavior) and enter the following:

#!/bin/sh
/sbin/iwconfig wlan0 power off

acima de exit0, em seguida, salve o gedit, feche

Faça:

echo "options rt2800usb nohwcrypt=y" | sudo tee /etc/modprobe.d/rt2800usb.conf 
sudo modprobe -rfv rt2800usb 
sudo modprobe -v rt2800usb

Reinicie

No seu roteador mude a criptografia para WPA2-AES, é preferível; não qualquer modo misto WPA e WPA2 e certamente não TKIP. Em segundo lugar, se o seu roteador for capaz de atingir N velocidades, você provavelmente terá mais sorte com uma largura de canal de 20 MHz na banda de 2,4 GHz em vez de 20/40 MHz automática. Você também terá mais sorte com um canal fixo, 1, 6 ou 11, em vez da seleção automática de canais. Depois de fazer essas alterações, reinicie o roteador.

Em seguida, defini o IPv6 como Ignore no Network Manager: IPV6

Verifique se o gerenciamento de energia está desativado agora:

iwconfig
