Resetting the Router to Factory Defaults
To reset the router to factory defaults, press and hold the
Reset
button (
1
) on the back of
the Telephony Gateway for more than fifteen seconds. This restores the wireless setup
configuration and router configuration parameters to the factory defaults. You may need to
do this if a misconfiguration has locked out all access.
Booting from Battery
The TG2472 supports a “Boot from Battery” feature that allows the Telephony Gateway to
provide continued telephone service during power outages.
To start the TG2472 from its battery, follow these steps:
1.
If a battery is already installed in the Telephony Gateway, remove it.
2.
Re-insert the battery into the Telephony Gateway (see
Battery Installation and
Removal
(page 16) for details).
3.
Press the
Reset
button (
1
); the Power light should turn on immediately.

Troubleshooting
The Telephony Gateway is plugged in, but the Power light is Off
Check all power connections. Is the power cord plugged in firmly at both ends?
If you plugged the power cord into a power strip, make sure the strip is switched on.
Avoid using an outlet controlled by a wall switch, if possible.
Finally, check the fuse or circuit breaker panel.
I'm not getting on the Internet (all connections)
It may take over 30 minutes to establish a connection the first time you power up your
Telephony Gateway, especially when many people are online. Always leave your Telephony
Gateway plugged into AC power and connected to the cable system.
Check the front panel lights:
The
Power
and
Online
lights should be on.
If the
Power
light blinks for more than 30 minutes, call your cable company for
assistance.
Check your cable connections. Connectors should be tight. The coax cable should not be
pinched, kinked, or bent sharply—any of these can cause a break or short in the cable (you
may have to replace the cable). If you have one or more splitters between the Telephony
Gateway and CATV outlet, remove the splitters and connect the Telephony Gateway
directly to the outlet.
Proceed to the Ethernet or wireless solutions if necessary.
I'm not getting on the Internet (Ethernet)
If you are using a hub, is the hub turned on?
Are you using the right type of Ethernet cable? Use the supplied cable for direct connection
to a computer; use a cross-over cable for connection to a hub.
Press the
Reset
button on the back of the Telephony Gateway.
A misconfiguration could lock out all access to the Telephony Gateway router. If you think
this has happened, see
Resetting the Router to Factory Defaults
(page 37).
I'm not getting on the Internet (Wireless)
Check the indicator lights, see
Using the Telephony Gateway
(page 33) — the Wi-Fi light
should be on.

Troubleshooting
Does your connection utility discover your wireless LAN? If you turned off “Broadcast
SSID” you need to manually enter the name of your wireless LAN in the connection utility.
Change your security mode to “disabled”. Enable one of the other security modes as soon
as you find the problem.
A misconfiguration could lock out all access to the Telephony Gateway router. If you think
this has happened, see
Resetting the Router to Factory Defaults
(page 37).
My wireless Internet connection stops working sometimes
This is usually caused by interference. Two common sources are 2.4GHz “remote”
telephones and microwave ovens. If you cannot remove the interfering product, try using a
different channel or setting Protected Mode.
I can get on the Internet, but everything is slow
If the Web site you are visiting is very popular, that site may be having trouble servicing all
the requests. If other sites download quickly, wait for a few minutes and try again. Usage
during peak hours may also affect the connection speed.
Other communications on the LAN, or interference with wireless connections, may slow
down your connection.
I don't have a dial tone when I pick up the phone - why?
In order for telephone service to be functional on the Telephony Gateway, telephone
service must have been purchased from the service provider and configured on your
Telephony Gateway. The following steps should help in identifying the source of the
problem.
1.
Is the Power LED lit?
•
If not, check to make sure the Telephony Gateway is plugged in and the outlet has
power.
•
If the LED is lit, go to the next step.
2.
Is the Online LED lit?
•
If not, check the coax connection at the Telephony Gateway and the wall. Ensure
they are connected and tight. If they are and you do not have dial tone, contact your
service provider.
•
If the Online LED is lit, go to the next step.
3.
Is the Telephone (Tel 1 or Tel 2) LED lit?
•
If not, phone service has not been set up on that line. Contact your service provider.
•
If it is blinking, there is a phone off hook somewhere in the house. Find that phone
and hang it up.
•
If it is lit, go to the next step.
4.
Is the phone plugged directly into the Telephony Gateway?
•
Make sure the phone is plugged into the port on the back of the Telephony Gateway
labeled “Tel 1” for line 1, and “Tel 2” for line 2.

Troubleshooting
•
If so, try a different phone. Make sure the new phone is a working phone.
•
If a known good phone is used and you still don’t have dial tone, try a different
phone cable. If a new phone and cable do not restore dial tone, call your service
provider.
5.
Is the Telephony Gateway plugged into a wall outlet?
•
If so, unplug the phone connector at the back of the Telephony Gateway and plug in
a known working phone. If you now have dial tone, the problem is with the house
wiring. Contact your cable company or a qualified wiring technician to correct the
house wiring. If you still do not have dial tone, contact your service provider.
