After logging in to your optical modem through a mobile phone or a computer, turn to the network configuration page of the optical modem to change the WIFI password on the WLAN2.4G configuration page and the WLAN5G configuration page. “SSID” is the WIFI name, while “WPA Pre-authentication Shared Key” is the WIFI password. The adjustment will become valid without rebooting the machine.

Connect an optical modem through a mobile phone or computer wired or wireless. Input 192.168.1.1 in the browser, and click the "Enter" button to jump to the login page. A device info label can be seen at the back of each optical modem, showing the account name and password for login. Usually, the account name is "Local Web Login User Account", "Local Web Login Username and Password", "Default Terminal Configuration Accountant", or "Default Terminal Configuration Password".

The default WIFI username and password are on the label which is at the back of the optical modem. The WIFI username is after the title "SSID-1 name" or "Default WIFI network username". The wireless password is usually after the title "SSID-1-WPA Key" or "Default WIFI Network Key (WPA-PSK / WPA2-PSK)". And as for 5G WIFI, we add "-5G" at the end of the WIFI username. If you forget the changed WIFI username/password, you can easily adjust them again by logging in to your optical modem.

If you have changed the login password of your optical modem and forgotten it, you could reset it by pressing the "Reset Button" next to the Internet port for 5 seconds. After rebooting the device, you could log in through the default user account on the label. If it does not work, please contact the maintenance of the operator for further help.

Check the "Phone" indicator on the optical modem. If the light is on or flashing, users can make phone calss normally. Then please check if the telephone wire is connected properly and if the backup power supply of the phone is working. If the "Phone" indicator is off, please check the power supply and the optical fiber. If the power supply and optical fiber are in standard condition while your optical modem still dose not work, contact the mantainer of the operator please.

Please call the customer service staff of your operator to check if your current broadband service is stopped and if there is any overdue bill by logging into the website of the operator. If your account is normal, please check whether the wired or wireless network is connected properly and whether you can log into your optical modem with your computer. If you still can not access the internet, please contact the maintainer of the operator.

If the WIFI signal cannot be found, please examine whether the WIFI turns on by observing the WIFI indicator. Usually, it is marked as “2.4G”, “5G”, or “WIFI”. If the indicator is off, you can turn on the WIFI by pressing the button near the port, or by logging into your optical modem.

If your TV receives no signal, please check if the set-top box is on. And If an error prompt appears on the TV after normally booting the set-top box, please check if the network cable between the set-top box and the optical modem is connected. When they are connected, the indicator light of the Internet port on the optical modem should be on or flashing. If the cable is connected correctly, but the set-top box still can not work, contact the maintenance of the operator for further help.
