Chào các bạn,
Hôm nay mình gặp trường hợp như sau:
- Trước mình dùng Internet bình thường với cái modem khuyến mại của Viettel
- Giờ mình có thêm một em Zyxel wireless router nữa. Mình cấu hình như sau:
Modem: 192.168.1.1 <--> (WAN) Wireless Router: 192.168.2.1 <--> laptop
và tình hình thế này:
- Mình vào Internet bình thường
- Nhưng ở một số trang như: HVA, facebook, ... mình không post dữ liệu lên được (ví dụ như gửi bài hoặc up ảnh).
- Không cứ là dùng wifi, mình cắm dây mạng vào cổng LAN trên Router cũng bị tình trạng này.

Trường hợp này là bị cái gì vậy mọi người? À, mình đang dùng Firefox trên Gentoo nhé.
PS: Mình thử với 2 trường hợp sau thì đều OK (post bài ầm ầm)
+ Để nguyên thế này restart và boot vào Windows
+ Cắm dây từ modem vào cổng LAN của wireless router + disabled DHCP trên router

trường hợp của anh quanta giống trường hợp của đứa bạn gái em cách đây 1 năm 6 ngày 
Ban đầu mạng chỉ có MODEM Siemens ------ Desktop
Nhưng do nhu cầu muốn có wifi nên em đã đi mua thêm AP Tenda W541R và cắm vào thì bị y như anh đang gặp phải bây giờ
http://forum.uitstudent.com/showthread.php?7407-Kh%C3%B4ng-m%E1%BB%9F-%C4%91%C6%B0%E1%BB%A3c-mail-trong-h%C3%B2m-th%C6%B0-v%C3%A0o-Blog-post-b%C3%A0i-t%E1%BA%A1i-c%C3%A1c-4rum
Vấn đề em không biết xuất phát từ đâu, hồi năm ngoái em chỉ check bằng PING, Browser.
Hiện tượng như mô tả ở dưới, em cứ cắm con Wifi TENDA ------ modem Siemens là y như rằng không post được bài trong các forum
Đợt đó em phải xử lý bằng cách mang con Switch 4 port tới (mất oan con Sw) kết nối như sau
Modem siemens ----- Switch ----- Wifi >>>>>>> Laptop
|
---------- Desktop
Thì mọi thứ lại ổn định
Em nghĩ chắc chỉ do xung đột gì đó giữa 2 con Wifi Tenda và Modem siemens
Tình trạng của mình bị như sau :
- Nhà đứa bạn có 1 Desktop + 1 Laptop
- ban đầu chỉ có 1 Modem Siemens SE560dsl khuyến mại của FPT j đó kết nối Desktop, do nhu cầu mắc Wifi để Laptop cũng kết nối đc internet nên mình mua 1 con AP TENDA W541R 54Mbps chuẩn B, G .
- máy desktop vào tất cả mọi trang đều bình thường trừ những trường hợp sau :
+ không mở được mail mặc dù đã vào được hòm thư Inbox trong Yahoo, cứ click vào 1 mail nào để mở là đứng đơ luôn
+ không mở được trang 360.yahoo.com
+ không post được bài lên các 4rum
Chú ý : Máy tính ko bị nhiễm virus j cả vì khi mình không nối trực tiếp AP TENDA với Modem SIEMENS mà test thử bằng cách Modem ---- Switch ----- AP Tenda và Desktop thì tất cả chạy bình thường không bị 3 hiện tượng trên
và mình mang AP TENDA về nhà test với Modem TP-LINK khuyến mại của VNPT thì chả có vấn đề j xảy ra cả
Không biết do xung đột phần cứng giữa con Modem Siemens --- AP TENDA không nữa
AP TENDA để cấu hình mặc định hết : 192.168.0.1/24 range IP
DHCP Server
mình chỉ cấu hình key WPA2 cho con AP TENDA ngoài ra ko làm j khác, ko chặn port hay bất cứ j cả
Ai biết fix lỗi này xin chỉ giùm , không thì phí con Switch 4 port quá

| @tuewru: của bạn là AP à? Sao không bỏ modem ra, cắm thẳng đường ADSL vào con TENDA? |

đợt đó em chưa biết config AP chạy như là modem
Em xem qua hướng dẫn trên mạng config AP với modem có sẵn chỉ việc disable DHCP của nó (cho con Modem làm DHCP) rồi cắm vào chạy luôn
Và 1 lý do nữa là FPT fix MAC address nên em muốn cắm thẳng line ADSL vào con AP TENDA thì phải gọi tổng đài nó change MAC cho thì mới vào được mạng |

@quanta: bạn thử với distros khác xem có bị tình trạng như Gentoo không?

Chắc hơi ngại, nên thôi. Cảm ơn bạn.
Như đã nói, mình cắm dây từ modem vào cổng LAN (tất nhiên là đã đổi IP thành 192.168.1.199 chẳng hạn), disable DHCP trên wireless router thì dùng bình thường rồi nhưng vẫn muốn biết vấn đề là ở đâu? |

Nếu được quanta vui lòng post những thông tin này:
. Caputure trên Windows trong trường hợp nối qua port WAN
. Capture trên Gentoo trong trương hợp nối qua port LAN
. Thử trên distros(dùng livecd) khác trong trường hợp nối qua port WAN
không tiện thì thôi nha vì mình cũng chỉ muốn tham khảo thêm thôi.

Cái trường hợp này mình cũng bị, cả năm trời chả biết vì sao (xài FPT), xài wireless thì không thể thực hiện đc những hành động thuộc về POST. DOWNLOAD thì vẫn OK
Nhưng tình cờ chuyển sang xài mạng VNPT thì không xảy ra trường hợp này nữa, vẫn post ầm ầm lên forum. Hỏi thì mới biết thì ra mỗi cột phát sóng của FPT nó có chặn dịch vụ "gì đó" mà cái anh đó nói mình ko nghe đc, nghe đc X-Lam gì đó. |
