Cannot access Internet (Ethernet)
Solution:
1. If you are using a hub, is the hub turned on?
2. Are you using the right type of Ethernet cable? Use an Ethernet cable for direct
connection to a computer; use a cross-over cable for connection to a hub.
3. Press the
Reset
button on the back of your telephony modem.
Accessing Internet is very slow
Cause:
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 may slow down the connection.
No dial tone when I pick up the phone
Symptom:
For telephone service to be functional on your telephony modem, the service
must have been purchased from your service provider and configured on your telephony
modem. The following steps should help in identifying the source of the problem:
Solution:
1. Is the Power LED lit?
a. If not, check to make sure your telephony modem is plugged in and the outlet
has power. Use only the external AC power adapter (if provided) and power cord
included with the equipment.
b. If the LED is lit, go to the next step.
2. Is the Online LED lit?
a. If not, check the coax connection at your telephony modem and the wall. Ensure
they are connected and tight. If they are and you do not have dial tone, contact your
service provider.
b. If the Online LED is lit, go to the next step.
3. Is the Telephone (Tel 1 or Tel 2) LED lit?
a. If not, phone service has not been set up on that line. Contact your service provider.
b. If it is blinking, there is a phone off hook somewhere in the house. Find that phone
and hang it up.
c. If it is lit, go to the next step.
4. Is the phone plugged directly into your telephony modem?
a. Make sure the phone is plugged into the port on the back of your telephony modem
labeled "“Tel 1" for line 1, and “Tel 2” for line 2.
