BT Hub Flashing Purple – What Does It Mean?

When it comes to the purple light on your BT Hub, there are two situations you may experience – a solid and a flashing purple light. No matter which Hub you are using at the moment, and this applies to BT Smart Hub, BT Smart Hub 2, and Ultrafast Smart Hub, the meaning is the same:

A flashing purple light on your BT Hub indicates that the Hub is working properly, but the broadband isn’t working.

Therefore, we have gathered some tried and tested solutions for this issue. Hopefully, you will have this issue fixed by the end of this article.

How to Fix the BT Hub Flashing Purple Light?

There are several different things you need to check and try to fix this problem on your own. So, let’s begin!

Is Your Broadband Activated?

If your broadband isn’t activated yet, it won’t work. As a result, you will see the purple light blinking on your BT router. Sometimes it can take a few hours until your broadband gets activated, so you have to be patient. Once it is activated and your broadband connection becomes fully operational, the purple light will disappear.

Check for Power or Service Outages in Your Area

When there is a service interruption, you will likely see your BT Hub flashing purple since the broadband connection isn’t working properly.

To check whether a power or service outage is the main reason for your problem, you can install the My BT app on your smartphone. There are both Android and iOS versions available.

Another way to check for service outages is from the Check BT Service Status page. All you need to do is to enter your landline number in the required field, and you will be able to see the service status in your area.

Check BT Service Status

If you find out the main reason for the flashing purple light is indeed a power or service outage, you need to be patient, and hopefully, your ISP will resolve the problem soon. However, if that’s not the main reason, we recommend you skip to the next step.

Check If the Broadband Cables Are Properly Connected

The simplest thing to do here is to check your broadband cable, and whether it’s connected properly to the right sockets or ports. 

When you do this, make sure to check both ends of the cable. Also, make sure that the connections are not loose. The best way to do this is to disconnect and connect everything again making sure everything is fit and tight.

Broadband Cables Are Properly Connected

If you are using a Fiber connection, the ends of the cable will be gray. If you are using a Full Fiber connection, the ends of the cable will be red.

So, one part of the Ethernet cable should be connected to the modem’s port and the other end should go into the WAN port of the Hub. When you use an Ethernet cable it is important to hear a clicking sound when you plug the cable into the Ethernet port.

After you make sure everything is connected properly, check the LED light again and see whether it’s still flashing purple. If it is, try the following solution.

Check if the Micro-Filter Is Properly Connected (If You Are Using One)

The micro-filter is necessary if you want to use a phone service and broadband connection at the same time. Without the micro-filter, there are high chances to experience broadband problems that may result in the flashing purple light, or you may hear noise on the phone line.

So, the same thing we have said about the broadband cable applies to the micro-filter if you are using one. Make sure that all the cables are properly and firmly connected.

Have You Upgraded to BT Smart Hub?

If this is the case, all you have to do now is to connect the Super Smart Hub to the phone socket. There is no need to use a modem anymore. Trying to use a modem along with the Smart Hub (or Super Smart Hub) will result in a purple blinking light on your Hub.

Frequently Asked Questions

Question: Should I Reset My BT Hub to Factory Default Settings?

Answer: Normally, this is the last solution you should try. Although it will fix the issue in most cases, it is necessary to configure the router and the network from scratch after a factory reset. Why? Because factory reset deletes all custom configurations. 

Find the reset button at the back of the router and press it with a paper clip or a pen. Keep it pressed for 10-15 seconds, and it will reboot. When it boots up again, it will be reverted to its default settings.
