How to fix: BT Hub Flashing Purple Light

Fixing the flashing purple light issue on BT Hub is fairly easy, considering the root problem can be easily deciphered thanks to the precise color of the light that directly indicates a faulty internet connection. Here are the best ways to fix BT Hub flashing purple light: 

1. Incorrect broadband configuration

When the BT Hub flashes purple light, it indicates an inactive internet connection from the broadband’s side. Therefore, the first course of action should always be to check whether the broadband connection is configured properly. 

Check the BT Hub’s broadband wiring from both ends and see if the connection is established properly. BT Hub has a dedicated broadband socket in grey color with the word broadband above it. Any loose wiring or wire cutting will cause the connectivity to fail, resulting in no internet connection. You can also try to disconnect and reconnect all wiring to ensure it is properly settled.

2. Power cycle the BT Hub

Sometimes the broadband connection can bottleneck with the BT Hub software. Power cycling can fix the purple light flashing issue in this scenario. To power cycle the BT Hub, simply switch it off by removing the power cord. Now, wait for about a minute or two and switch it on. This method can be used to fix all kinds of electronic devices that need a resting and recalibration phase due to continuous intense use.  

3. Check for BT Service Outage

BT service outages are extremely rare. However, like most online platforms, they do occasionally occur due to maintenance and other similar reasons. Go and check whether there is a service outage at the time of facing the purple light flashing issue. If there is an outage, the best course of action is to wait for uptime. 

4. Wait for activation

If you just switched to a new broadband connection, you will need to wait until your internet service provider activates it for you to use. If you miss the bill and the internet connection gets deactivated, this can also occur. In this case, quickly pay your bill and let the internet connection activate again. 

5. Contact BT Support

If nothing works for you and you are certain the hardware part of the broadband connection is accurate, the best fix is to contact BT support directly. BT is a large brand with a dedicated team of representatives who are available at all times to aid users’ problems. Do not hesitate to connect with them to fix the purple light issue.
