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?
/lib/firmwarelalu muat ulangiwlwifiJawaban:
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.
