What is the situation when the broadband cat power light is not on

See if there is a problem with the connector, a loose thread, or a telecom problem. Take a closer look thank you, hope!

I guess it's because the cat is broken, you can change the hair and try it.

The reason why the broadband cat has only one power light on:

1. The back line is not plugged in, in this case, please check whether the back connecting lines are plugged in, whether the line itself is intact, whether the crystal plug is connected reliably, and whether the connector is intact.

2. The network card of the computer is faulty. Check whether the NIC driver is installed, whether the NIC itself is damaged, and whether the NIC is firmly inserted. If the NIC is damaged, replace it.

3. The broadband modem itself is faulty. In this case, you need to send the cat for repair, or change the cat.

1. Light modem. Plug in the power supply, all indicators do not light up, turn off the power socket of the optical modem.

Restart, if it doesn't work, try a different cat, and if it doesn't work, ask a professional to repair it.

2. How to set up the optical modem.

1) Step 1: Set the IP address of the computer and the settings of the gateway ADSL by accessing the settings page of the browser. By default, the IP address of ADSL is set to the same network segment as ADSL on the computer connected to ADSL.

You can access the ADSL settings page, specifically set the IP address of the computer to, X is generally greater than 2, the gateway is set, and then open the browser, enter the IP address of ADSL on the address bar, that is, you can access the ADSL settings page. The IP address is set here to access ADSL, and the gateway is set up to surf the Internet later.

2) Step 2: Enter the default username.

and password access to the ADSL settings screen is required to use a username and a password to authenticate. The default username of the HUAWEI MT800 is admin, and the default password is admin. Note that this username and password is not the username and password of the telco company, but the username and password of the ADSL device.

After entering the correct information, you can enter the ADSL settings page.

3) Step 3: Enter the ATM page to set the route, click the ATM link, and you can enter the setting page. Find the Connection Type option, select the single option of PPP, and the PPP setting will be displayed at the bottom of the page.

Set the username and password in the PPP settings, where the username and password are your account and password for telecom (or other ISP providers), and the settings here are for ADSL to automatically dial when the phone is turned on.

4) Step 4: Set up the automatic IP address assignment function, i.e. DHCP function, each computer on the network has a separate IP address, in the same network, the IP address of each computer is unique. Usually when we surf the Internet, the computer is set to automatically obtain an IP address, that is, when the computer is connected to the network, the server will automatically assign a unique IP address to the computer, just like the floor, row number, and seat number indicated on the ticket when you enter the theater.

That is, each computer has a fixed IP address, and there is no exact same IP address in the same network, just as every room in a building has a fixed number. If your network uses the previous IP address assignment method, you need to enable ADSL's automatic IP address assignment service, that is, set DHCP. On the DHCP page, select DHCP Server

A single option will do.
