Problem and Troubleshooting
NO.
Solution:
First, check whether the ZXHN H168NW is at normal
state (check the indicators against this User Manual).
If yes, check the computer or application network, not
the VDSL2. If the VDSL2 Modem has problems, then
check the status of indicators one by one to debug
the fault.
It is recommended that you check the following
points before you seek help from operators:
1. The VDSL2 telephone cable connectors are in
good condition.
2. The VDSL2 is away from the power cable and
large-power electronic devices.
3. No telephone extensions and fax machines are
installed between the VDSL2 incoming line and the
splitter.
4. The splitter is correctly installed.
5. The VDSL2 Modem is not over-heated.
4 Password verification failure.
Issue description: Modem synchronization and
connection are normal. However, sometimes the
password fails to be verified.
Solution:
1. The account and password are case sensitive and
some accounts contain a domain name.
2. Virtual dialup software: It is possible that
sometimes the virtual dialup software is faulty, or
conflicts with other software in the operation system.
In such cases, it is suggested to re-install the dialup
software or replace it with valid software.
3. Network adapter drive program may be faulty.
4. Not pay on time. Pay on time in such cases.
