YouFibre broadband checker
Start with the YouFibre address check, then validate real performance with capable wired hardware, upload tests and latency checks. This keeps availability and full-fibre troubleshooting together.
- Check YouFibre availability: Confirm whether YouFibre full fibre appears available for the address before comparing plans.
- Interpret multi-gig results: Check cables, switches, network cards and device capability before assuming the service is underperforming.
- Separate package from performance: Fast symmetrical fibre can still be limited by router queueing, Wi-Fi or old client hardware.
YouFibre ONT, router and device-capability isolation path
Test the ONT/router path first, then cables, switches and device network cards. A very fast package is only useful if the connected hardware can actually process and receive it.
For YouFibre lines that are fast at idle but lag under traffic, run the Bufferbloat Test, compare with the Loaded Latency Test and check drops using the Packet Loss Test.
Current YouFibre Wi-Fi 7 and legacy router paths
Current YouFibre support material covers the YouFibre Hub and Hub Pro with Wi-Fi 7, while existing customers may still have eero, Arris or Asus equipment. Identify the exact model before applying port, LED, reset or mesh advice.
- Hub or Hub Pro: connect the router WAN port directly to the fibre ONT using the supplied Ethernet cable and wait for the internet light to settle.
- Older devices: current YouFibre Hub guides describe a separate Wi-Fi name containing
_legacyfor older devices that need WPA2 or the 2.4GHz and 5GHz bands. - Existing eero installations: use the eero app and its model-specific port limits rather than assuming the current YouFibre Hub instructions apply.
- Arris or Asus installations: follow the exact router guide shown in YouFibre support and record the model before factory resetting.
Diagnosing YouFibre multi‑gig and device bottlenecks
- Wired speed is strong: focus on Wi‑Fi and end-device limits.
- Speed caps below package rate: check cable, switch and network-card capability.
- Latency jumps under load: test bufferbloat and router queue handling.
YouFibre ONT, Hub and eero status lights
YouFibre full fibre has two separate fault layers: the optical wall box on the Netomnia network, and the router or mesh gateway that distributes the connection around the home. Check both before changing Wi‑Fi settings or blaming the package.
| Hardware light status | What it usually means | Most useful action |
|---|---|---|
| ONT LOS red, flashing or solid | Loss of optical signal. The fibre feed is not reaching the ONT correctly. | Do not keep rebooting the router. Photograph the ONT lights and contact YouFibre support because this usually needs a network or ONT fault check. |
| ONT power and PON steady green | The wall box has power and the XGS-PON optical path is registered on the access network. | The external fibre path is likely healthy. Move on to the ONT-to-router Ethernet cable, router port, Wi‑Fi and client hardware. |
| Hub or Hub Pro internet light solid white | The current YouFibre guide describes solid white as the normal online state. | If performance is poor, check the device, Ethernet path, Wi-Fi band and port capability rather than the optical line first. |
| Hub or Hub Pro internet light flashing white | The router can be connected to the network while normal website browsing is not yet working. | Wait for setup or software updates to finish, then check the ONT-to-WAN cable and use My Account or support if the state persists. |
| eero solid white | For installed eero setups, solid white means the gateway eero is online and working normally. | Focus on the client device, Ethernet port speed, Wi‑Fi range or mesh placement rather than the external line first. |
| eero solid red | The eero is offline or cannot reach the internet through the ONT. | Power down the ONT and eero. Turn the ONT on first, wait about two minutes for the service lights to settle, then power the eero back on and check the Ethernet cable. |
| eero yellow / orange light | On eero hardware this usually points to a power-supply problem, not a normal line-authentication state. | Use the original eero power supply where possible, then retest. If the eero stays offline, use the ONT-first restart sequence above. |
| eero blinking blue | The eero is in Bluetooth pairing mode during setup. | Use the eero app to complete setup before judging speed, latency or packet loss. |
Optimising YouFibre full-fibre performance
- Hardware readiness: Check network cards, USB adapters and switches before expecting multi-gigabit results.
- Cable standard: Use a known-good Cat6 or Cat6a copper path for wired tests. A higher category label alone does not fix a 1Gbps port, switch or network-card bottleneck.
- Correct router port: Multi-gigabit packages need the high-speed LAN/WAN port on the supplied YouFibre Hub Pro, eero gateway or attached multi-gig switch. A standard 1Gbps port will usually cap real throughput around 940Mbps.
- Wi‑Fi expectation: Wireless may not match a fast symmetrical line unless router and device standards align. Current YouFibre Hub and Hub Pro hardware is designed around Wi‑Fi 7, but older installed eero or client devices can still be the bottleneck.
- Loaded testing: Run tests during uploads because symmetrical packages are often used for cloud backup and streaming out.
Break the 940Mbps multi-gigabit port trap
If a YouFibre 2000, 7000 or 8000 package repeatedly tests at about 940Mbps over Ethernet, the service may not be the limiting factor. That ceiling is often caused by a 1Gbps network card, switch, docking station, router LAN port or cable path.
- Find the multi-gig port: use the fastest LAN/WAN port on the supplied router or mesh gateway for the high-speed device or multi-gig switch. On eero Pro 6E setups, only one Ethernet port is 2.5Gbps; on newer high-end hardware, use the 10Gbps-capable interfaces where supplied.
- Upgrade the client interface: a normal laptop or motherboard Ethernet port is often 1Gbps only. For 2Gbps, 7Gbps or 8Gbps tests, use a 2.5G/10G PCIe network card, a quality multi-gig USB adapter or a Thunderbolt 3/4 to 10Gb Ethernet adapter.
- Use the right cable path: replace damaged or unknown patch leads with known-good Cat6 or Cat6a copper cables for the ONT-to-router, router-to-switch and switch-to-device path.
- Remove hidden 1Gbps equipment: old wall ports, powerline adapters, cheap switches, TV docks and mesh nodes can silently downrate the path even when the package and main router are multi-gig capable.
Isolate loaded latency on a symmetrical YouFibre line
High headline speed does not prevent queueing delay. Cloud backup, game downloads, security cameras and large uploads can still make calls or gaming feel poor when the router or one device fills a queue.
- Record the idle baseline: run ping and packet-loss tests over Ethernet when the connection is quiet.
- Repeat under load: run the Loaded Latency and Bufferbloat tests while another device uploads and downloads.
- Compare wired and Wi-Fi: a clean wired result with a poor wireless result points to coverage, interference or the client rather than the fibre service.
- Control the traffic source: pause backup, console updates or camera uploads one at a time to identify which flow creates the delay.
- Escalate with evidence: if wired latency and packet loss remain poor with known-good hardware, keep timestamps and screenshots for YouFibre support.
YouFibre full-fibre evidence checklist
Show whether the bottleneck is the service, router, cabling, account profile or connected device.
- Record the physical ONT light pattern, especially power, PON and any red LOS state, before power cycling.
- Record the YouFibre Hub or eero LED state before changing router settings.
- Run a wired test using a known capable device and cable.
- Check whether switches, adapters, router ports or cables cap the path around 940Mbps.
- Run loaded-latency and bufferbloat tests during upload activity.
- Compare same-room Wi‑Fi with wired results before changing package.
- Record whether a static-IP add-on, customer-owned router, custom DNS, VPN client or local security software is involved when one service fails but ordinary browsing works.
YouFibre fault pattern table
| YouFibre symptom | Most useful next check | Likely fault layer |
|---|---|---|
| Wired speed caps unexpectedly | Check Ethernet port and cable limits. | Cable, switch or NIC |
| ONT LOS light is red | Use the ONT and router light key and photograph the wall box before rebooting. | Optical line, ONT or access-network fault |
| eero or router is offline after a power cut | Restart the ONT first, wait about two minutes, then restart the router and check the Ethernet lead. | ONT-to-router WAN handoff |
| Symmetrical multi-gig package caps around 940Mbps | Use the multi-gig port trap checklist and verify client card speeds. | 1Gbps NIC, switch, router port or cable bottleneck |

Run a wired speed test →Check the contract end date, any early-exit charge and exact-address availability before moving to another altnet, Openreach retailer or cable network.
Read switching rights →Static IP, port forwarding and inbound access checks
YouFibre lists Static IP as an optional add-on. Before changing router rules, confirm the active addressing profile and rule out local double NAT or a customer-owned firewall.
- Compare addresses: compare the router WAN address with a public IP result. A private or shared WAN address needs provider confirmation before ordinary IPv4 port forwarding can be expected to work.
- Check the add-on: confirm that Static IP is active in My Account and that the router has renewed its address after activation.
- Rule out double NAT: if a second mesh or firewall sits behind the YouFibre router, use access-point or bridge mode where supported, or forward through both devices deliberately.
- Check IPv6 separately: YouFibre publishes an IPv6 support article, but router and device support can vary. Confirm the current account and hardware configuration rather than assuming a particular prefix size.
- Test from outside: verify remote access from mobile data or another external connection; a device inside the home may not support NAT loopback.
When YouFibre troubleshooting is no longer enough
If YouFibre is strong on a capable wired device, fix cabling, router ports, switches, Wi‑Fi and client hardware before blaming the provider. If the ONT shows red LOS, the router cannot get online after an ONT-first restart, the direct multi-gig wired path remains unstable with known-good hardware, or inbound access fails after confirming the addressing profile, preserve the evidence and contact support or compare local full-fibre alternatives.
Focused answers
YouFibre Broadband FAQs
Use these answers after identifying whether the problem sits in the optical line, current Hub, legacy router, local hardware, loaded traffic or addressing profile.
Which router hardware does YouFibre currently use?
Current YouFibre support material covers the YouFibre Hub and Hub Pro with Wi-Fi 7. Existing installations can still use eero, Arris or Asus equipment, so identify the exact model before applying port, light or reset advice.
What does a red LOS light on the YouFibre ONT mean?
A red or flashing LOS light indicates loss of optical signal at the wall-mounted ONT. Photograph the lights and report the fault rather than repeatedly rebooting the router.
Why can a multi-gigabit package test at about 940Mbps?
A result around 940Mbps usually points to a 1Gbps network card, router port, switch, dock, wall socket or cable path. Test through a confirmed multi-gigabit interface before treating it as a service fault.
How do older smart-home devices connect to a Wi-Fi 7 Hub?
YouFibre's current Hub guides describe a separate network whose name includes _legacy for older WPA2, 2.4GHz or 5GHz devices. Use the Wi-Fi key printed on the Hub and connect the older device to that network.
Does YouFibre offer a static IP address?
YouFibre lists Static IP as an optional add-on for fixed addressing and remote access. Confirm the current price and activation route in My Account before changing port-forwarding or remote-access rules.
Can I leave if a YouFibre speed problem is not resolved?
Use the minimum-speed commitment in your order summary and YouFibre's current guarantee and complaints process. YouFibre is not listed among the current signatories to Ofcom's voluntary residential Broadband Speeds Code, so do not assume that code's automatic 30-day exit process applies.
