If the normal situation can be through the card to test their own broadband network speed.

LAN Light Status Description

LAN lamp for the cat with the computer or LAN device connection led, in the computer or LAN equipment has been on the electricity, and the normal conditions for the illuminated steady, the partial brand cat LAN lights with the CAT network data transceiver LED role, will be flashing with data transmission. Different brand models of cat to the LAN lamp identification method may be different, Huawei Cat logo for LAN, lan,ut-Cat logo for the Pc,d-link logo for the Ethernet, Alcatel identified as a operated symbol. After the computer or network equipment on the electricity, this lantern light, if not bright, indicating that the network cable is not plugged in or the network cable has broken.

Data Transmission Light Status description

TX Lamp for sending data indicator, RX for receive data indicator, normal communication, two lights will be with data transmission flashing. Different brand models of the cat on the data transmission indicators may be different methods, some will be identified as data, and some with the link lamp or LAN light reuse. The Alcatel cat has no such indicator.

A: Users who often surf the internet for up to six months, to power off the shell of the device to open, clean up the dust inside the equipment

B: Placing the equipment in a safer place for people, opening the lid of the equipment, using air convection to strengthen the contact surface with the air, natural heat dissipation;

C: To install micro-fan equipment, increase the convection of the air, for forced cooling;

D: If you are doing it, I suggest you: after disconnecting the power supply, the heating parts of the equipment are fitted with heat sinks.

E: After disconnecting the power, use 3 mm drill to drill a lot of holes in the equipment, strengthen the air flow, improve the heat dissipation conditions;

F: The equipment as for ventilated dry place, it is best to do an insulating bracket, the equipment to support the natural heat dissipation;

G: In time to clean up the garbage debris generated by the Internet, regularly organize the operation of C disk, you can properly improve the speed of operation.

H: First let the ADSL cat sync: The Cat power off after the reboot.
