No.
Problem and Troubleshooting
First check whether the ZXHN H368C is in the normal state (Check the
indicators according to this user’s manual). If yes, the computer or application
network may be faulty. This is unrelated with VDSL2. If the VDSL2 MODEM is
abnormal, check the status of indicators one by one to remove the fault.
It is suggested to check the following items before seeking help from operators:
1. The VDSL2 telephone cable connectors are proper.
2. The VDSL2 is away from the power cable and large-power electronic
devices.
3. No telephone extensions and fax machines are connected between the
VDSL2 incoming line and splitter.
4. The splitter has been installed correctly.
5. The VDSL2 MODEM has good heat dissipation ratio.
