Velocidade de wifi lenta no Ubuntu 16.04

1

Estou ficando muito lento na velocidade do Wi-Fi no Ubuntu, não sei qual é o problema.

Eu tentei todas as soluções disponíveis na internet, mas não parece melhorar.
Também não detecta a mudança de rede, se eu passar de um wifi para outro eu tenho que reiniciar o gerenciador de rede e os serviços de rede para detectar o novo wifi.

Estou pensando em migrar para o Windows 10 se nada der certo.
