Câu hỏi Wi-Fi cho HP 17-y020ca trong Ubuntu 16.04 luôn bị tắt hoặc "chưa sẵn sàng"


Gần đây tôi đã mua Máy tính xách tay HP 17-y020ca và cài đặt XUbuntu 16.04. Máy tính xách tay này có thẻ không dây Broadcom Corporation BCM43142.

Thẻ không dây này ban đầu không được phát hiện (nhưng thẻ ethernet hoạt động tốt) và tôi đã làm theo hướng dẫn tại:

Có thể sử dụng wifi Broadcom BCM43142 trong Ubuntu 16.04 không?

và bây giờ thẻ dường như được phát hiện chung và "Bật WiFi" được cung cấp dưới dạng tùy chọn hoạt động (không chuyển sang màu xám) trong trình đơn Mạng của tôi trong XFCE.

Khi tôi nhấn "Enable WiFi", menu này thường sẽ thay đổi trạng thái để cho biết rằng nó được kích hoạt thông qua một dấu kiểm bên cạnh "Enable WiFi". Tuy nhiên, khi điều này xảy ra, một trong hai điều xảy ra tiếp theo trong menu. Hoặc là nó nói:

"Wi-Fi bị tắt" hoặc là "Wi-Fi chưa sẵn sàng"

Tôi đã chạy tập lệnh info.bash không dây và bao gồm bên dưới.

Tôi thực sự biết ơn vì bất cứ lời đề nghị nào mà ai cũng có thể cho. Tôi đánh giá cao sự cân nhắc của bạn!

Trân trọng, Nathaniel Osgood

Điều này có thể được cố định bởi một lệnh đầu cuối

sudo tee /etc/modprobe.d/blacklist_acer.conf <<< "blacklist acer_wmi"

Wi-Fi sẽ hoạt động sau khi khởi động lại.
