Fiber Internet Basic Troubleshooting

STEP 1: Restart your wireless router. Restarting your wireless router is the most common fix for in home WiFi issues. Simply unplug the router’s power cord from the wall outlet or power strip, wait a few seconds, then plug it in again. (Do NOT press any buttons on the router during this step.) Check to see if you are now able to get online. If not, proceed to Step 2.

STEP 2: Determine what type of fiber equipment you have installed.

In addition to the router shown above, find the other device that the technician installed inside. Which one below does it look like?

If you have device A, B, or C, go to Step 3.

If you have device D, go to Step 4.

Step 3: Check the cabling between the TP-Link router and the ZTE fiber unit. Be sure the cabling is plugged in the same as shown in the picture below. Be sure there is power to both devices. If no LED lights are lit, double check the power outlet they are plugged into. On the ZTE side, there will also be a separate fiber patch cord plugged into the Optical port (will be yellow or blue in color – not shown in photo). This cable usually goes to a plate mounted on the wall. Make sure this cable is not kinked or damaged in any way.

Step 4: Check the cabling between the TP-Link router and the Gigabit POE. Find the device below and make sure it is plugged in according to the diagram. The Internet port on the TP-Link is always a different color (usually blue). Make sure the dongle is plugged into the Internet port and not one of the other LAN ports

Step 5: Check the lights on the top of the TP-Link router. Most routers have indicators lights on the top. Look for them according to the diagram below and troubleshoot accordingly.

NOTE: In some rare cases, you may have a power supply that looks like the ones below rather than the white ethernet dongle. If you do, please ensure the cabling is connected according to the diagrams shown below.
