In-depth analysis of common problems of broadband CAT Network Interfaces

In-depth analysis of common problems with the broadband CAT Network Interface, to help you with the broadband cat network interface, the following broadband CAT Network Interface should help you. Have you set the home wireless route? Do you know the general steps of the broadband CAT Network Interface? If your broadband CAT Network Interface is set to cause frequent disconnection when you access the Internet, you can see the following article to solve all the problems.

After installing M0n0Wall, I continued to work on the broadband network over the past two days, and made research on the network interfaces of the old Big-bandwidth modem in the warehouse. When the network cable sequence problem occurs, in general, the same type of devices are connected, using a crossover network cable, a network of different devices, and a direct connection network cable. In my own language, vswitches belong to type A. vrouters, computer hosts, broadband cat network interfaces, and network telephone terminals should belong to type B.

But for the broadband CAT Network Interface, it seems that different manufacturers are different, that is, the same manufacturer, and different models seem to be different. The current trend is that the switch itself has a AUTO-MDIX function, switch cascade does not need to connect cascade ports or do cross lines, but the router with Broadband Router WAN port ), broadband CAT Network Interface and other equipment still does not provide the AUTO-MDIX function, Huawei's argument is to consider the cost, and the other end of these equipment is usually connected to the switch, there is no need to repeat the AUTO-MDIX function.

Traditionally, the broadband cat network interface should be connected to a router using a crossover line, the broadband CAT Network Interface should also be connected to a computer using a crossover line, and the computer using a direct connection to the broadband router LAN port, the Ethernet port of a computer connected to a traditional router should use a cross line, and the router connected to a switch should use a direct line. The router must be connected to a cross-line router.

If the uplink port is not used for vswitch cascade, the crossover line should be used. The uplink port is used for the first end of the vswitch cascade, and the direct connection is used for the first end of the normal port. If you use uplink ports at both ends of a vswitch for Cascade, you still need to use crossover lines. Why? Negative. Of course, I don't believe who will do this silly thing, just to explain the truth.

On my M0n0Wall, both are 3Com 3c905B NICs, And the NIC must be connected using the Asus AAM 6005HW broadband CAT Network Interface in the cross-line order, if you change the bell CyberLink 6307YG, you must use the direct link sequence. Otherwise, No carrier is displayed in the status of the broadband CAT Network Interface in M0n0wWall. Of course, this is irrelevant to M0n0Wall compatibility and is a hardware underlying signal problem.

Huawei MT 800 can be used in the normal line sequence, and the cross line sequence is not tested. Another Asus AAM 6000EV can also be used as a normal network cable. If you encounter these problems, it is best to read the instructions provided by the manufacturer, but I cannot find them here. Note: The rear panel of Asus AAM 6005HW has a conversion switch, hubpc. if it hits the pc, you can use a normal network cable to connect to the NIC.
