Problemas com o Dell XPS 9550 wifi

4

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:

Depois de passar muito tempo pesquisando como resolver meu problema, percebi que a melhor solução era trocar minha placa wireless por uma Intel.
Desta forma, não só eu resolvi meus problemas de rede sem fio, mas também meus problemas de Bluetooth.

Eu sei que esta resposta não era o que eu esperava, mas se eu soubesse, teria gasto 20 $ e 2 minutos para mudar há muito tempo.

Então, meu conselho para qualquer um que tenha problemas com o wifi do Dell XPS 9550 é mudar o cartão wifi (usei este: Intel Wireless Dual Band AC 8260NGW 867Mbps WIFI Card Bluetooth 4.2 8265NGW).

Eu também gostaria de agradecer @ chili555 pelo seu tempo.
