Intel Centrino Wi-Fi de alta ping para roteador no Ubuntu 15.10

Eu tenho um Ubuntu Mate 15.10 instalado.

Ontem notei que a internet ficou lenta. Eu tentei fazer o ping do roteador e a latência foi algo acima de 2000 ms por 6000 ms.

A correção temporária para isso é:

sudo modprobe -r iwlwifi
sudo modprobe iwlwifi
sudo systemctl restart network-manager

ou alterne isso por uma tecla de atalho wi-fi no teclado

Então funciona, mas depois de 5-10 minutos isso acontece novamente.

Eu tentei:

dpkg-reconfigure o network-manager e o linux-firmware
reinstale-os (linux-firmware 1.149.3 e network-manager 1.0.4-0ubuntu5.2)
faça downgrade deles (para linux-firmware 1.149 e network-manager 1.0.4-0ubuntu5)
desative o modo N (opções iwlwifi 11n_disable = 1)
ative a agregação de links (opções iwlwifi 11n_disable = 8)
sudo iwconfig wlp4s0 desligar
pare o bluetoothd
direcione o roteador de outro dispositivo - sem problemas
use wifi no Windows 10 no mesmo laptop - sem problemas

mas o problema ainda existe.

Respondendo a minha pergunta: O problema estava em (grande surpresa) pulseaudio e é recurso de soquete de rede (eu estava experimentando com isso). Então, eu desliguei e o problema desapareceu
