pada edisi pengembang Dell XPS 13 saya (2014). Saat ini saya mengalami masalah aneh dengan wifi saya (saya menggunakan Networkamanger dengan nm-applet untuk KDE):
1) pada tingkat yang paling dangkal saya mengamati bahwa kadang-kadang itu bekerja dengan sempurna:ketika saya mem-boot pc saya, itu sudah terhubung ke wifi, dan kadang-kadang itu tidak akan terhubung dengan cara apa pun (wifi selalu sama);
2) Saya mencoba me-restart NM:dan masalahnya tetap ada .
3) Terkadang, jika saya me-reboot laptop saya berfungsi lagi, terkadang tidak.
4) Saya mencoba menggunakan nmcli
nmcli connection up My-WiFi
lalu saya amati

3) Jika saya menggunakan pelindung eth kabel usb, saya dapat terhubung dengan NM tanpa masalah;
Terkait:Lulus F10 ke aplikasi di terminal Gnome?
4) Saya juga mencoba untuk terhubung langsung dengan wpa_supplicant , tetapi tidak mungkin, karena kesalahan autentikasi namun Saya tekankan bahwa userid dan pwd saya benar karena terkadang saya dapat terhubung tanpa masalah
Apa yang harus saya lakukan?
Jawaban yang Diterima:
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, semuanya terpecahkan. Sebelumnya saya mencoba setiap saran di internet tanpa hasil.
EDIT:Masalahnya adalah beberapa klien dhcpcd. Sistem sekarang juga stabil dengan wpa_supplicant.
