FTTC Router Sync Status: Difference between revisions

'Sync' is your modem's ability to talk to your local green cabinet. Most, if not all, modems/routers will have a LED that shows the sync status. This is often the LED labeled DSL, and generally speaking on is in sync, and flashing or off means no sync.

 

This can help diagnose a fault, as if the router is not in sync then the problem lies between the router and the your local green cabinet. It could be:

*the router

It does mean though, that the fault is unlikely to be with your computer or your internal network.

 

This is a table of popular VDSL/FTTC modems and routers and how you can tell if they are in sync or not by looking at the LEDs on the device. You can often gain more information by looking at the diagnostic pages on the router's web interface, but this will help you tell at a glance if the modem is in sync or not.
