Các pro cứu em ca này với.
Hiện tại em đang dùng mạng 40mbs của VNPT
em đặt router chủ ở tầng 1 và kéo 1 đường dây lên tầng 3.
Em config khác lớp:
IP chủ: 192.168.1.1
IP tầng 3: 192.168.0.1
Nhưng dạo này ko hiểu tại sao mạng ở t3 bị chập chờn, ping rớt gói tăng ping liên tục còn ping ở t1 thfi rất đều và mạng dùng rất tốt.
Em đã thay dây, thay cả router ở tầng 3 nhưng vẫn bị.
Em cònig lại cho cùng lớp vẫn bị
Các bác giúp em với ạ

Hiện tại chỉ có 2 máy kết nối ở tầng 3nhưng mạng vẫn chập chờn

Ping ở tầng 3 đây ạ, càng về đem thì nó rớt càng nhiều ạ
