Atualização 14 de outubro de 2014: todo post
A situação (por speedtest.net):
Meu notebook com Wi-Fi embutido atinge velocidade máxima de 3,3 Mb / s para um roteador específico.
Outros computadores podem obter 20-40 Mb / s lá.
Um deles também é Ubuntu
mas driver diferente ( iwl3945
como eu me lembro).
Depurado da seguinte forma:
nm-tool
below) n
= 3,3 Mb / s, adaptador USB temporário g
= 15 Mb / s; nm-tool
é realmente transmitida pelo mesmo roteador, mas gerenciada pelo ISP, o login e o passe são necessários); n
padrão, porque essa é uma rede de equipe (embora deva tentar algum tempo); Ainda não tentei:
Alguma idéia sobre configurações, drivers ou qualquer coisa, na verdade?
