Eu tenho um laptop HP com o Kubuntu 16.10 com duplo boot ao lado do Windows 10.
Acabei de atualizá-lo a partir de 16.04 e, de repente, TF2, Discord, Portal 2 e outros programas estão passando por ping flutuante, de decente (faixa de 20 a 50ms) a tremendamente horrível (430 a 500ms). Eu tentei atualizar o kernel para o 4.10.5 (a última versão estável), mas após a reinicialização ele não fez nada.
Eu tenho um adaptador de rede sem fio Realtek RTL8188EE como minha placa Wifi.

Como você pode ver, não há perda de pacotes em ambos, e o ping está completamente bem, exceto em alguns lugares no ping do Google.
Eu tentei olhar muitos outros sites para corrigir o problema, nenhum deles funcionou. O gerenciamento de energia do laptop está desligado (meu laptop está conectado diretamente à energia de qualquer maneira - não há uma bateria). O kernel é o mais atualizado possível (sem ser instável). Eu não tenho absolutamente nenhuma idéia do porque meu ping no TF2, Discord, e outros programas é tão alto e flutuante tanto.
