O uso do Realtek 8732be em um HP Stream 11 é extremamente lento

Eu tenho um novo HP Stream 11-r001nd. Eu consigo me conectar à minha rede, mas é muito lento. Mesmo quando coloco meu laptop e o roteador ao lado um do outro, é muito lento assistir a um vídeo do youtube (se a página web do youtube não carregar). No Windows 10, esse problema não existia.

Nesse vídeo do youtube , é mostrado que, usando a versão 14.10, a velocidade era aceitável. Mas essa versão não é mais suportada.

Eu olhei os resultados do seu script sem fio.

Você tem duas mensagens de erro. Error: nmcli (1.2.0) and NetworkManager (1.1.93) versions don't match. Force execution using --nocheck, but the results are unpredictable. Isso foi reportado como bug 1590335 por outro usuário, mas uma reinicialização foi corrigida para eles.

Aparece para mostrar que o firmware incorreto está sendo carregado em um dispositivo sem fio USB.

No entanto, o seu problema real parece ser Cartão Realtek Wifi RTL8723be Não está funcionando corretamente . Siga os passos indicados na solução.

Se isso resolver seu problema, clique na marca de seleção à esquerda para mostrar que seu problema foi resolvido. Se não repostar a saída do script wifi, de preferência depois de resolver os outros dois erros. O primeiro deve desaparecer depois de uma reinicialização. O segundo não aparecerá se você remover o dispositivo USB antes de executar o script.

Eu observei os resultados da sua segunda execução do script sem fio. Vamos ver alguns fragmentos:

Isso mostra uma conexão sem fio funcionando perfeitamente e recebendo quase um gigabyte de dados. O próximo fragmento

Mostra que o adaptador sem fio está funcionando em circunstâncias difíceis. É como se estivesse sendo preso.

Isso mostra que o congestionamento está vindo de um ponto de acesso chamado HP-print-C3-Deskjet 2540 series. Sugiro alterar o canal de RF do ponto de acesso ou da impressora para que eles estejam em canais diferentes. No momento, ambos estão no canal 1. Os únicos outros canais usados são 6 e 7, então você tem muito por onde escolher.

A impressora está agindo como um ponto de acesso porque você pressionou o botão direto da conexão sem fio (consulte a página 53 do manual do usuário). Você deve ter conectado sua impressora ao roteador seguindo as instruções na página 49 do manual. O manual do usuário está disponível on-line aqui
