Question

Meu modelo sem fio é:

De acordo com o rótulo: BCM943142Y

De acordo com o lspci: BCM43142 (rev 01)

O ID da minha placa de rede é: 14e4: 4365 (rev 01)

bcmwl-kernel-source está instalado, e a coisa do software do Ubuntu diz que o meu dispositivo WiFi wlo1 está usando. Este é o driver correto.

Conectar-se ao meu hotspot de telefone funciona bem, então eu posso acessar a internet com ele. Eu só recebo muitos dados, e é muito lento. Não consegue se conectar a todas as outras redes aqui na minha universidade e no meu dormitório. Olhando através de syslog , ele desiste de conectar quando expira, dizendo que não conseguiu obter a configuração IP. Eu tinha janelas antes e o WiFi funcionava perfeitamente.

Não tenho certeza se esse é o log correto ou a parte correta do log, mas aqui está algo em /var/log/syslog que parece relevante:
