Troubleshooting
YOUR INTERNET CABLE IS NOT PLUGGED IN MESSAGE
If you get a "Your Internet cable is not plugged in" message when trying to set up
your router:
1. Make sure that an Ethernet or Internet cable (or a cable like the one supplied with
your router) is securely connected to the yellow INTERNET port on the back of the
router and to the appropriate port on your modem. This port on the modem is usually
labeled Ethernet, but may be named Internet or WAN.

2. Make sure that your modem is connected to power and is turned on. If it has a power
switch, make sure that it is set to the ON or l position.
3. If your Internet service is cable, verify that the cable modem's CABLE port is con‑
nected to the coaxial cable provided by your ISP.
4. Or, if your Internet service is DSL, make sure that the DSL phone line is connected to
the modem's DSL port.
5. If your computer was previously connected to your modem with a USB cable, discon‑
nect the USB cable.
Install the router again.
