Menggunakan Ubuntu 11.10 (Unity 3D) dan koneksi internet kabel (DSL) tanpa router atau modem.
Jika saya memutuskan koneksi internet saya, saya bisa menghubungkan kembali dengan mengklik ikon manajer jaringan dan memilih koneksi dari menu drop down karena koneksi saya terlihat. Tidak perlu memulai ulang manajer jaringan.
Tetapi setiap kali koneksi internet turun dengan sendirinya , saya telah membuka terminal dan menggunakan sudo service network-manager restart
karena saya tidak melihat koneksi di menu drop down manajer jaringan. Hanya setelah perintah, manajer jaringan kemudian mulai dan terhubung secara otomatis.
Apakah ada beberapa pengaturan sehingga manajer jaringan tidak harus dihidupkan ulang setiap kali koneksi turun (sebagai lawan dari pemutusan saya ketika tidak perlu restart)?
Saya kira dengan kata lain, saya tidak ingin manajer jaringan berhenti selama saya menggunakan komputer, terlepas dari apakah koneksi saya ke ISP terputus atau tidak.
Bukan masalah besar untuk membuka terminal dan mengetik perintah dan kata sandi, tetapi jika ada cara untuk memastikan bahwa manajer jaringan tidak berhenti, itu akan lebih baik.
