Quick answer: Replacing or adding a router behind an ONT requires the provider’s supported WAN handoff, authentication, IPv6 and service-feature details.
What this page covers
Collect the current provider documentation before entering any WAN value.
Step-by-step workflow
- Identify ONT and provider service type.
- Check whether the handoff is DHCP/IPoE, PPPoE or another documented method.
- Confirm voice/TV and support dependencies.
- Test rollback before disconnecting the existing equipment.
Decision table
| Check | What it tells you | Safe next action |
|---|---|---|
| Exact scope | The page is limited to the named model, platform or provider | Match the current official source |
| UI or firmware | Menus and behavior can change | Check the exact version or revision |
| Unknown detail | No safe universal claim is made | Use the official support path |
Limits and verification
Never invent PPPoE credentials, VLAN IDs or prefix sizes. Use the provider’s current guide or support channel.
