Cisco router 880 và kết nối thông qua giao diện 3G

Mình có một anh bạn được tặng một router 880 series của Cisco, router này chỉ có mỗi giao diện Cellular 0 để kết nối vào internet thực chất giao diện này là một modem 3G có gắn sẵn SIM của Vinaphone. Ngoài ra thiết bị còn có 4 giao diện Ethernet để cho các máy tính trong LAN kết nối internet thông qua giao diện Cellular kia

Do không có tài liệu đi kèm nên mình mò trên Internet để cấu hình thử, kết quả là báo lỗi tùm lum (khi debug dialer thấy rất nhiều lỗi mà mình không thể giải quyết nổi).

Vậy xin nhờ admin, mod và các bạn hỗ trợ dùm.

Mình gửi các thông tin liên quan đến thiết bị này ngay sau đây.

P/S: SIM 3G của Vinaphone vẫn kết nối internet bình thường nếu dùng với USB 3G lắp ngoài.

Rất momg được sự hỗ trợ từ các bạn.

modem có quay số đi rồi đó bạn. Nhưng cái chatscript "vinaphone" chưa đúng.

Để quay số 3G của Vinaphone thì bạn phải dùng số nào?
