If your PC is connected to a hub or gateway, try connecting the PC directly into an Ethernet port on the
cable modem.
If you are using a cable splitter, try removing the splitter and connect the cable modem directly to the
cable wall outlet. Wait several minutes for the cable modem to re-establish communications with the cable
service provider.
The Ethernet cable may be damaged. Try another cable.
IMPORTANT:
Some Ethernet cables may be labeled Category 5e, but only have 4 wires (2 pairs).
These cables will only negotiate 100Mbps maximum. True Cat5e and Cat6 cables have 8 wires (4
pairs), which are required to support 1000Mbps (Gigabit Ethernet).
