Belong modem lights – what they mean
| Light | Meaning | What to do |
|---|---|---|
| Power green | Gateway is on | Normal |
| Online/Internet solid green | Online | All good |
| Internet red | No connection / authentication issue | Restart; if it stays red, check line/settings |
| DSL/WAN flashing | Trying to sync / connect | Wait a few minutes |
| Wi-Fi green | Wi-Fi on (flashing = activity) | Normal |
| No lights | No power | Check the power switch and socket |
A flashing line light that never goes solid points to a sync/cabling fault; a solid line but red internet usually means a settings or authentication problem. We can tell them apart and fix the cause.
