Solution
Verify Internet settings or contact your ISP for assistance.
Reconnect the modem. Verify the connections are correct
using the quick setup documentation.
Verify that the Web browser is installed and set up to work
with your ISP.
Plug in cable/DSL modem. You should see a "power" LED
light on the front of the cable/DSL modem.
Try connecting to the Internet at a later time or contact your
ISP. (If the cable/DSL service is connected, the "cable" LED
light on the front of the cable/DSL modem will be on.)
Unplug and reconnect the modem, verifying connections.
Note that your PC may also have an Ethernet network
interface (also called a network interface card, or NIC) that
connects to a local area network (LAN). Although it looks
similar to the modem connector, the RJ-45 Ethernet network
connector is not the same. Verify that you are using the
modem connector. Do not connect a telephone cable to the
NIC. Do not plug a network cable into a telephone service
line; doing so may damage the NIC.
