Acak “menghilangkan autentikasi berdasarkan pilihan lokal (Alasan: 3 = DEAUTH_LEAVING)”

saya sedang berlari

uname -r
4.10.6-1-ARCH

pada edisi pengembang dell XPS 13 saya (2014). Saat ini saya mengalami masalah aneh dengan wifi saya (saya menggunakan Networkamanger dengan nm-appletuntuk KDE):

1) pada tingkat yang paling dangkal, saya mengamati bahwa kadang - kadang berfungsi dengan baik: ketika saya mem-boot pc saya, itu sudah terhubung ke wifi, dan kadang - kadang tidak terhubung dengan cara apa pun (wifi selalu sama);

2) Saya mencoba me-restart NM: dan masalahnya tetap ada. 3) Kadang-kadang, jika saya reboot laptop saya itu berfungsi lagi, kadang tidak.

4) Saya mencoba menggunakan nmcli

nmcli connection up My-WiFi 

lalu saya amati

3) Jika saya menggunakan et eth kabel usb saya dapat terhubung dengan NM tanpa masalah;

4) Saya mencoba juga untuk terhubung secara langsung wpa_supplicant, tetapi tidak mungkin, karena kesalahan otentikasi namun saya menekankan bahwa userid dan pwd saya sudah benar karena kadang-kadang saya dapat terhubung tanpa masalah

Apa yang harus saya lakukan?

Saya melihat Anda menjalankan NetworkManager dan wpa_supplicant. Laptop saya (Inspiron 7590) dengan kartu wifi Intel 9560-ac memiliki masalah yang sama. Setelah mengganti wpa_supplicant dengan NetworkManager hal-hal diselesaikan. Sebelumnya saya mencoba setiap saran di internet tanpa hasil.

EDIT: Masalahnya adalah beberapa klien dhcpcd. Sistem sekarang stabil dengan wpa_supplicant juga.
