    Router Setup: Lights, Ports & Common Issues

    Your router quietly does a lot. Here's how to read it at a glance and fix the routine stuff yourself. Exact light colours vary by model — check the quick-start card that came with yours.

    What the lights usually mean

    Most routers follow a similar pattern:

    • Power: solid = on; off = no power (check the plug and socket).
    • Internet / WAN: solid = online; flashing = connecting; red or off = no connection to the network.
    • Wi-Fi: solid or flickering = broadcasting; off = Wi-Fi switched off.
    • Phone (Digital Voice): solid = phone service registered.

    Which port does what

    Port labels vary, but these are the common ones:

    • DSL / Broadband: to the master phone socket (part fibre).
    • WAN (often blue or red): to the ONT on full fibre.
    • LAN 1–4 (often yellow): wired devices such as TVs, consoles and PCs.
    • Phone / Tel: your home phone handset on Digital Voice.

    The two-minute restart

    Turn the router off at the wall, wait 30 seconds and turn it back on. Give it 5 to 10 minutes to reconnect before testing. A restart clears most temporary glitches.

    Factory reset (last resort)

    Holding the reset pin for 10–15 seconds wipes all settings, including your Wi-Fi name and password and any own-router PPPoE details. Only do this if we ask you to, or if you have your connection details to hand.
