Meu Wi-Fi não está funcionando após o login. Eu não tenho ideia de por que ele começa a funcionar depois de fazer manualmente um rmmod & amp; & amp; modprobe.
Eu acho que há algo errado com a ordem durante o boot.
Abaixo estão dois trechos do meu dmesg. O primeiro é durante o boot normal.
O segundo pertence ao meu passo rmmod / modprobe manual.
Você tem alguma ideia do que eu posso fazer para corrigir isso?
