Estou recebendo vários tipos de problemas com a mais óbvia a baixa velocidade e baixo sinal. Mais raramente, estou recebendo desconexões ou o gerenciador de Wi-Fi continua pedindo a chave sem fio (embora eu esteja digitando a chave certa).
Além disso, após a suspensão, não há redes no gerenciador de rede e todas as seleções ficam esmaecidas.
Além disso, no dmesg eu tenho um monte de:
brcmf_cfg80211_reg_notifier: not a ISO3166 code (0x30 0x30)
e brcmf_inetaddr_changed: fail to get arp ip table err:-23
Algumas informações sobre minha rede sem fio:
