Quando estou perto do modem, meu sinal de Wi-Fi está às vezes cheio, às vezes metade ou inferior.Mas quando estou relativamente longe do sinal é preciso.Eu sei disso porque eu uso o Windows 10 em dual-bot, e sinal no Windows é força semelhante quando longe de modem, mas quando estou perto está cheio.
Isso acontece no Ubuntu 16.04; 17.04 e agora em 17.10 que eu uso agora. Também acontece em distros que são baseadas no Ubuntu: Zorin os, Elementary, Mint.Eu tentei todas elas.
Eu tentei:
Atualizando drivers de wifi.
Removendo e instalando novamente.
Desativando o IPv6.
Desativando o gerenciamento de energia do wifi via: sudo iwconfig wlp2s0 power off
O problema ainda persiste.
