ke dalam pos Anda karena ini mungkin terkait dengan bug dengan pengacakan alamat mac baru. Terima kasih telah membantu kami membantu Anda!Jawaban:
Saya memiliki masalah yang sama saat memperbarui dari 16.10 ke 17.04. Masalahnya dipecahkan dengan menambahkan baris berikut ke
/etc/NetworkManager/NetworkManager.conf
dan kemudian me-restart komputer.sumber
Elder Geek
dan komunitas untuk menemukan dan memperbaiki bug yang mungkinNetworkManager
(systemctl restart network-manager
) dan mungkin mencabut dan pasang wifi harus cukup :).Saya menghadapi masalah serupa setelah memutakhirkan dari 16.10 ke 17.04. Kemungkinan hal ini terjadi karena alamat MAC perangkat Anda secara acak. Anda dapat memverifikasi itu dengan memeriksa alamat MAC Anda menggunakan
ifconfig
perintah (jika Anda ingat alamat aslinya).Bagaimana cara memperbaiki:
Tambahkan baris berikut ke
/etc/NetworkManager/NetworkManager.conf
:Sekarang simpan file dan mulai ulang manajer jaringan menggunakan:
Sekarang reboot.
