The Internet Light On The Router Will Not Come On - Telstra TG797n V3 Getting To Know Manual

The Internet Light on the router will not come on:

The Light on your router will be solid green when your ADSL line is connected
and synchronised. If it isn't solid green, then there could be an issue with the
filtering of your telephone devices, or a problem with the telephone line at
your exchange.
Please check:
1. That every telephone device sharing the line with your ADSL router has a
filter on it. Affected devices can include any telephones, dial-up computer
modems (including internal modems), fax machines, answering machines,
back-to-base alarm systems and FOXTEL Digital installations.
2. That you have not connected the router into a filtered socket.
3. Whether there are any telephone extension leads connecting any device on
the telephone line, including your ADSL router (extension leads can cause
problems on the line).
4. Whether there is work being done on your line at the exchange. Please wait
30 minutes and check again.
If the light still does not come on solid green, call Telstra Business Technical
Support on 13 2999 and advise that you may have a 'Sync Fault'.
