If Ziply Fiber Wi-Fi is connected but has no internet, check Ziply outage status, then check the ONT and router lights. Restart the ONT if accessible, wait for it to settle, then restart the router. If you changed routers, ask whether a cached MAC or lease needs to clear.
Do not start by resetting every device. If all devices connect to Wi-Fi but cannot browse, the break is usually before the device: ONT, router WAN, DHCP, DNS or provider service.
Ziply Wi-Fi can work while the fiber path is broken
Ziply Fiber no-internet problems often show up as a strong Wi-Fi network with nothing behind it. Your phone, laptop or TV may connect to the router, but pages fail because the router is not getting a clean path from the ONT. The cause can be an outage, ONT issue, loose Ethernet cable, cached MAC address, DHCP lease, DNS failure, router swap or a third-party mesh setup that was never handed internet correctly.
Start by separating local Wi-Fi from the outside service. If every device is offline, stay focused on Ziply equipment, the ONT and the main router. If only one device fails, move later to DNS, VPN and saved network checks.
Quick diagnosis table
Try these fixes in order
Work from the fiber box inward: outage status, ONT, router WAN, then individual devices.
- 01
Check Ziply outage status
Use mobile data to check whether Ziply reports a known issue before changing home settings.
- 02
Check the ONT
Look at the fiber terminal lights and power. If the ONT is dark or warning, the router is not the first problem.
- 03
Restart ONT, then router
If accessible, power the ONT first, wait for it to settle, then power the router.
- 04
Inspect Ethernet from ONT
The ONT should feed the router WAN/Internet port with a seated cable.
- 05
Consider cached MAC after router swaps
If one router works and another does not, Ziply may still associate service with the previous device.
- 06
Check DNS only after WAN works
If the router has internet but websites fail, automatic DNS is the cleanest test.
- 07
Call when the ONT path fails
If direct ONT or router handoff will not work, support may need to release a lease or check equipment.
Detailed checks
The ONT is the real starting point
Ziply fiber enters through an ONT before it reaches the router. The router can still broadcast Wi-Fi even when the ONT is not passing internet.
- That is why Wi-Fi bars do not prove fiber service is healthy.
- Check the ONT and router WAN before changing passwords.
Router swaps create a common trap
Users often move an Orbi, Nest, ASUS or Eero router from another provider to Ziply and see Wi-Fi with no internet.
- The router may be fine, but the ONT handoff or cached MAC can block the new path.
- Restart order and support lease release can matter more than Wi-Fi settings.
DNS failure can look like total outage
If the router has a WAN address but websites fail by name, DNS may be involved.
- Try automatic DNS or a known DNS provider for one careful test.
- Do this after confirming the ONT and WAN link are alive.
One-device problems stay small
If one iPhone, laptop or TV fails while others browse, Ziply service is probably working.
- Forget the network, disable VPN, check private DNS and compare the device near the router.
- Do not rebuild the fiber setup for one stubborn client.
What to record before calling
Write down ONT lights, router light color, whether Ethernet works, whether you changed routers and whether all devices fail.
- Those details help support decide whether to release a lease, check the ONT or troubleshoot your router.
- A clear pattern saves time.
Release IP tools can help in the right case
Ziply's support material mentions releasing your IP address through app tools. That can matter when the connection is alive but the router handoff is stuck.
- Use it after checking outage status and cables, not as a replacement for ONT troubleshooting.
- If the router never receives a WAN address, the IP release clue is worth mentioning to support.
New installs can need assignment work
Some Ziply issues are not caused by your router at all. In apartments or new units, service may be physically installed but not assigned correctly to the address.
- That kind of problem will survive router restarts.
- If a technician says the ONT is working but no internet is assigned, keep pushing for provider-side completion rather than buying equipment.
Mistakes to avoid
Do not ignore the ONT.
Do not assume a router swap is plug-and-play.
Do not change DNS before checking WAN status.
FAQ
Why is Ziply Fiber Wi-Fi connected but no internet?
Your device may be connected to the router while the ONT, outage status, DHCP lease, DNS or router WAN handoff is failing.
Check Ziply status, ONT lights and router WAN before resetting devices.
Can Ziply cache my router MAC address?
Some users report handoff trouble after changing routers, where the previous router still appears to matter.
A clean ONT/router restart or support lease release may be needed if the new router will not get internet.
Should I restart the ONT?
If accessible and safe, restart the ONT before the router, then wait for normal lights.
If the ONT will not come online, contact Ziply because the router cannot fix that path.
Why does my own router show Wi-Fi but no internet?
The router can broadcast Wi-Fi without receiving WAN internet from Ziply.
Check WAN IP, ONT Ethernet cable, DHCP lease and whether Ziply equipment works first.
Can DNS cause Ziply no internet?
Yes, especially if the router has a WAN address but websites fail.
Use automatic DNS for a clean test before trying manual DNS.
Can Ziply service be installed but not assigned?
Yes, especially in new buildings or recently activated units. The physical equipment can look ready while the account or address assignment is incomplete.
If multiple routers fail and the ONT appears healthy, ask support to confirm the service assignment, not just the router status.
When should I contact Ziply?
Contact support if the ONT lights are wrong, all devices fail, the router cannot get WAN internet, or a router swap keeps failing.
If only one device fails, troubleshoot that device first.
