Overview
'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.
Knowing the Sync status
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
- the wiring between the router and the main phone socket
- a problem with the actual phone line between you and the cabinet
- or even a fault with the cabinet itself.
It does mean though, that the fault is unlikely to be with your computer or your internal network.
Finding the Sync Status
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.
| Modem/Router | Sync LED Label | In Sync Status | No Sync Status | Notes |
|---|---|---|---|---|
| Openreach Modem | DSL | Constant Green | Flashing green or off | ECI or Huawei |
| ZyXEL VMG1312 | DSL | Constant Green | Flashing when trying to sync | Orange if it's syncing to ADSL |
| Technicolor TG589vn | Broadband | Constant Green | Flashing when trying to sync | |
| Billion 8200N | DSL | Constant Green | ||
| DrayTek Vigor 2760n | xDSL | Constant Green | Flashing when trying to sync | |
| FRITZ!Box 7390 | Power/DSL | Constant | Flashing when trying to sync | |
| Asus DSL-N66U N900 | DSL | Constant on | Flashing when trying to sync |
