Mình dùng modem của VNPT đưa thì được nhưng dùng router 1841 báo lỗi khi debug lên như vậy. Đã bị hành hơn cà tuần vẫn ko tìm ra lỗi nên nhờ mọi người giúp.

Đã cấu hình nhiều khu vực chạy bình thường vẫn dùng router 1841 và nhà mạng VNPT ko biết sao chỗ Biên Hòa lại bị như vậy.

Mong mọi người giúp đỡ mình.
