Problemas na comunicação com o roteador DHCP?

Question

minha rede doméstica tem problemas com computadores linux, dois ubuntu e dois mint. Eu dei uma olhada nos arquivos de log e procurei na internet sobre a solução. Não consigo encontrar um bigode de solução. Um dos computadores da menta se conecta bem, os outros três aparecem com o mesmo problema. Um PS3, Mac e todo o Windows se conectam bem.

Eu tentei:

• Desativando o IPv6 (não acho que meu roteador seja compatível com IPv6)
• Uso de dispositivo wlan USB, dispositivo WLAN interno ee cabo Ethernet (tudo isso funciona em outras redes / janelas)

Por isso, suspeito que este seja um problema com o fato de meu computador não poder se comunicar com meu roteador em um idioma comum. Mas eu não sou muito especialista. Espero que alguém se importe em ver meu arquivo de log. Acredito que a resposta esteja aqui.

Answer 1

Bem, eu posso responder a pergunta 50% agora, desde a compra de um novo roteador o problema se dissipou. Mas não consigo explicar porque x dos computadores eram incompatíveis.
