Adtran Slow Speeds
Experiencing slow speeds on your Adtran / Plume system? This guide is here to help! We understand how frustrating lag and buffering can be so our goal is to get you back and connected with good speeds once again.
Locate your ONT (Optical Network Terminal), shown in image, and unplug the power cable from the outlet. You should see all lights power off on the unit. Let the unit sit without power for approximately 20 seconds, then plug it back in.
Locate your router, it should be a tall gray or white tower similar to the following photo. We are going to repeat the same steps as the modem. Unplug the power cable from the outlet. You should see all lights power off on the unit. Let the unit sit without power for approximately 20 seconds, then plug it back in.
Notice: The lights on the units will be flashing and changing during the boot process. Allow the devices up to 5 minutes to finish booting. The lights should stabilize other than the 10GE and WiFi lights, which will be flickering.
Verify your modem and router cables are connected properly 👇
- Fiber cable - Verify that the fiber patch cable (typically yellow with green tip) is connected into the optical port on the ONT and to the white box (clamshell) on the wall. NOTE: in some rare instances the patch cable may run through your wall.
- Ethernet - Verify that the cable is connecting the ONT and the router. On the ONT, ensure that the ethernet cable is in the 10GE port, and to the router in the WAN port. If the cables are not in the correct location, you will need to move them. If they need to be moved, please reboot your router again once the change has been made. NOTE: in some rare instances, you may be utilizing the GE port. If this is the case the GE light will be green when connected, otherwise it would be off.
After these steps, please test your connection by resuming whatever activity you were experiencing the issues with.
If you would like, you can open a browser on a computer or cellular device and proceed to run a speed test from the following site. www.speedtest.net
Is the internet still slow? Try testing from another device to determine if it is an issue specific to one device or the whole network. If you are still having issues, please contact us to continue troubleshooting.
