A blinking pink light on your BT Hub can be alarming, and you are not alone. Many BT Hub users have experienced this issue, and with the right information, you can have your BT Hub up and running in no time. Read on to learn more about the blinking pink light on your BT Hub, its meaning, and how to fix it.
Key Takeaways
- A flashing pink or purple light means the BT Hub has no broadband reaching it, not a fault with the Hub itself; a steady blue light is the healthy state you want.
- On the BT Smart Hub 2 a steady purple light is different from a flashing one; it signals the Hub has switched to BT's EE mobile backup while the fixed line is down.
- You'll work the fix outward from the wall; check the broadband cable seating first, then the Openreach modem or ONT, then known area outages, and reboot the Hub last.
- A flashing pink or purple light is normal on a new line activation day and needs no action; activation can run right up to midnight, so repeatedly resetting only restarts the sync.
- If the light keeps returning or coverage is poor, you'll learn that BT supports your own router over PPPoE, so swapping in more capable kit such as a Wi-Fi 6 router or a mesh is a realistic upgrade.
Quick Answer: What Colour Your BT Hub Should Be
When your BT Smart Hub is connected to the internet and healthy, the light should be a steady blue. Anything else is the Hub telling you it is not fully online yet. Here is what each colour means at a glance:
- Blue (steady): connected and working normally; this is the colour you want.
- Orange: starting up or trying to connect to broadband; give it 10 to 20 minutes and it should turn blue.
- Flashing pink or purple: no broadband; the line is not reaching the Hub, usually a loose or faulty broadband cable.
- Red: a problem with the Hub or the line; restart it, and contact BT if red persists.
If yours is sitting on flashing pink or purple, that is the no-broadband state covered below, so read on for the full fix.

Understanding the Significance of a Flashing Pink Light on Your BT Hub
Facing a flashing pink light on your BT Hub can be a cause of concern for many. This guide explains what the flashing pink light means and how to fix it. This is an issue that many BT Hub users run into, and it can be concerning if you do not know the cause. Generally, a flashing pink light indicates that your Hub is in need of a reboot.
By rebooting your Hub, you can often resolve the issue and get your Hub working correctly again. In some cases, the flashing pink light may indicate that your Hub is experiencing difficulty connecting to the internet. If this is the case, you may need to contact your service provider for assistance. Knowing the significance of a flashing pink light on your BT Hub can help you determine the best course of action to take.
Solutions for a BT Hub Flashing Pink Light
A flashing pink light on a BT Hub can be an indication that the Hub needs to be reset. This can be done by pressing the reset button on the back of the Hub. While a reset can fix the problem, it is important to identify the underlying cause of the flashing pink light.
This can be done by checking the Hub's connection to the Internet and verifying that the Hub has been set up correctly. If the flashing pink light persists, it is advised to contact BT for technical support. Taking the time to identify and troubleshoot the issue can help to ensure that the BT Hub is working properly and that the proper connections are in place.
BT Smart Hub 2 Flashing Purple Light Explained
On the BT Smart Hub 2, purple is the colour you will most often see for this fault, and it points to the same no-broadband state as the older pink Hubs. A flashing purple light means the Hub itself is powered and healthy but it is not receiving a broadband signal down the line; in plain terms the Hub is working, yet there is no internet reaching it. It is worth knowing one Smart Hub 2 quirk: a steady (non-flashing) purple light is different, and it means the Hub has fallen back to BT's EE mobile backup while the main fixed-line connection is down.
Because the cause is the line rather than the Hub, the checks are the same no-broadband sequence, and we work outward from the wall:
- Check the broadband cable first: on the back of the Smart Hub 2 there is a grey socket labelled Broadband. Make sure the black cable with the grey connectors is pushed firmly into it and into the master socket; a half-seated cable is the single most common cause.
- Check the fibre or Openreach side: on Full Fibre installs the cable runs to a separate Openreach modem or an optical network terminal (the ONT). Confirm that box has power and a steady (not flashing or off) optical light; if its light is out, the fault is on the fibre side and BT or Openreach need to look at it.
- Confirm there is no area fault: sign in to the My BT app or account, which flags known outages and open Openreach faults in your area. If one is showing, the purple light is out of your hands and you simply wait for the fix.
- Reboot the Hub last: unplug it for 30 seconds and power it back on, then allow a few minutes for it to sync. If you would rather follow a clean, repeatable procedure, our guide to resetting a BT broadband router walks through it without wiping settings you need.
If the purple light persists after the cable, fibre and outage checks, the line genuinely needs BT engineering attention rather than anything you can fix at the Hub.
New Line Activation Day: Pink or Purple Is Normal for Now
There is one situation where a flashing pink or purple light is expected and needs no fixing at all. If you have just switched to BT or had a brand-new line installed, the Hub will sit on flashing pink or purple until the line is switched on at the exchange. BT activation is not instant; it can run right up to midnight on your activation day, so a Hub that has been blinking all afternoon is usually just waiting, not broken.
The safe approach on activation day is to plug everything in, leave the Hub powered on, and let it complete; resetting it repeatedly does not speed activation up and only restarts the sync each time. Check the activation date on your order emails or in the My BT app, and only treat the colour as a genuine fault once that date has passed and midnight has come and gone.
If the Hub has clearly given you trouble beyond activation and you are weighing up the hardware itself, our BT Smart Hub 2 replacement guide covers when a swap is worth it and what works on a BT line.
Upgrade Options When the Hub Keeps Playing Up
If the pink light keeps coming back, or the BT Hub simply struggles to cover the whole house, it might be time to think about better kit. The good news is that BT supports your own router over PPPoE, so a full swap is genuinely realistic; you keep your BT line and just put a more capable router in front of it. Be honest with yourself about expectations, though; a new router will not raise the line speed BT delivers. What it does fix is coverage, control and day-to-day reliability, which is usually where the real frustration lives.
For most homes our primary pick is the ASUS RT-AX86U Pro. It is a properly capable Wi-Fi 6 router with strong range, sensible parental controls and a stable track record, and it handles BT's PPPoE setup without fuss.

If the budget is tighter, the TP-Link Archer AX73 is excellent value and still a big step up from a standard hub. And if the real problem is dead spots in back bedrooms or a converted loft, a mesh like the TP-Link Deco X50 run in access-point mode will blanket the place reliably and sits happily behind the BT Hub. We dig into when a mesh beats a single router in our guide to wifi extender vs mesh, and there are more options in our roundup of the best wifi mesh systems for 2025.
