MODEM synchronization and connection are normal. However,
sometimes the password fails to be verified.
1. Note that 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 conflict with other software in the
operating system. At this time, you are suggested to reinstall the dialup
software or replace it with other software.
3. Network adapter drive program problem.
4. In arrears of fees. Pay the fee timely in this case.
5 What are reasons for ADSL synchronization failure (also referred
to link down or link establishment failure)?
If the ADSL suddenly fails to be synchronized (link down) during
application, usually the DSL indicator of the MODEM will not be
solid on. You are suggested for checkup in the following sequence:
1. First check the quality of incoming cables and incoming cable
connectors.
2. Install the ADSL Modem correctly based on the user guide, to
minimize the number of taps.
3. Check whether the telephone cables and ADSL are in good contact
or whether the telephone cables are normal.
4. Try to disconnect the splitter and directly connect the ADSL Modem
to the incoming customer cable end to ensure that the problem is not
due to improper installation or incoming customer line quality. If the
ADSL can be synchronized again, it means that installation of the
incoming customer part is improper. Please reinstall it according to the
user guide.
5. If the ADSL still fails to be synchronized after the ADSL Modem
has been connected to the incoming customer cable end, contact the
operators to check whether it is due to external line failure or Modem
failure.
