BT VERDE-FIJO on DSL router: Smart Hub stuck on green startup
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
A green light on your BT Hub means it is starting up, but if it stays green after 3 to 5 minutes instead of turning blue, startup has stalled. Check that you are using the supplied power adapter, turn the Hub off and on again, and press the factory reset button with a paper clip if needed.
Safety first
Stop and check this first
- Always use the original power adapter supplied with your BT Hub, and never open the Hub casing or power supply unit.
- Pressing the factory reset button with a paper clip returns the BT Hub to its default settings, clearing any custom changes made in Hub Manager.
Safe checks you can perform
- Wait the full 3 to 5 minutes for startup and sync to finish
- Check the supplied power adapter and turn the Hub off and on
- Use a paper clip to press the Hub factory reset button

What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Remote broadband test and Hub diagnosis with BT Support
What they doIf your BT Hub remains stuck on a green light after checking the supplied power adapter, rebooting, and pressing the factory reset button with a paper clip, contact BT to run a connection and Hub test.
They must show youthe results of BT's automated broadband test and whether the Hub responds to remote diagnostics.
In writingthe BT fault reference number and the outcome of the remote diagnostic check.
Replacement BT Hub dispatch or engineer visit via BT
What they doWhen BT confirms that the Hub cannot complete its startup sequence despite using the original power supply and performing a factory reset, BT arranges a replacement Hub or books an engineer visit.
They must show youthat the replacement Hub progresses past green to a steady blue light.
In writingthe BT replacement order reference or engineer appointment confirmation.

Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Wait the full 3 to 5 minutes for startup and sync to finish
- Who:
- you.
- How:
- leave your BT Hub powered on without unplugging cables for at least 3 minutes on BT Smart Hub 2 (or 5 minutes on BT Smart Hub 3) to see whether the light turns solid blue.
- Result that matters:
- allow normal startup and initial broadband sync (which usually takes about four minutes) to complete.
- If the light turns solid blue:
- your BT Hub has finished booting and is connected to broadband.
- If the light stays solid green past 3 to 5 minutes:
- check the power adapter and reboot the Hub.
- Evidence to keep:
- time when the Hub was powered on and time when you confirmed the green light was still solid.

Check the supplied power adapter and turn the Hub off and on
- Who:
- you.
- How:
- verify that you are using the original power adapter supplied with your BT Hub, then turn the Hub off and on again and wait another 3 to 5 minutes for it to boot.
- Result that matters:
- rule out an incorrect power supply and force a clean startup cycle.
- If the light turns solid blue after rebooting with the supplied adapter:
- the startup hang is resolved.
- If the light still stays green:
- perform a factory reset using a paper clip.
- Evidence to keep:
- photo of the power adapter label and the Hub light state 5 minutes after rebooting.

Use a paper clip to press the Hub factory reset button
- Who:
- you.
- How:
- if the light on your BT Smart Hub 2 still does not turn blue after turning it off and on again, use a paper clip to press the recessed factory reset button on the Hub and wait for it to restart.
- Result that matters:
- restore default Hub settings when a configuration issue keeps the unit stuck on green.
- If the Hub finishes resetting and the light turns blue:
- broadband connectivity is restored.

- contact BT for support.
- Evidence to keep:
- note of the factory reset attempt and the LED color 5 minutes later.

What it means
According to official BT Help ('What do the lights on my BT Hub or Complete Wi-Fi device mean?' covering BT Smart Hub 3, BT Smart Hub 2, BT Smart Hub, Ultrafast Smart Hub and BT Home Hub 4 and 5; other models may vary), a green light indicates that the Hub is starting up and normally turns solid blue within a few minutes (about 90 seconds on Smart Hub, at least 3 minutes on Smart Hub 2, and under 5 minutes on Smart Hub 3). If the light stays green beyond that window, the boot sequence is stuck or the wrong power adapter is connected. The green light alone never proves that the BT Hub is permanently faulty.
