BT Router Flashing Purple (No Nonsense Guide)

If you have BT router flashing purple or orange and pink lights then we think we can help! This article has been written as a quick guide that acts as a useful troubleshooting and helpful resource to help cure your purple light issues on BT.

If you are seeing a blinking purple, pink or orange light on your BT Home Hub, then that means that the hub is trying to find an internet connection.

The general cause of a purple light on BT Hub devices is a disconnected cable, a faulty line, or a faulty port on your BT Hub. If you are not seeing any lights then check your power cable is connected, as there should be a power light on at least.

Your BT Home Hub also has a red light, which indicates a general fault, so when you see this in addition to your BT router flashing pink, then you have a problem with your line or BT hub.

Great, so how do we fix the pink/orange/purple flashing lights and restore an internet connection then?

The first, and most basic technique is the Roy method from IT Crowd: “Have you tried turning it off and on again?”

Resetting your router will generally solve basic problems like a frozen hub or a line synchronization issue. After a few minutes, and if everything is well, then your router should return to normal with a blue light once it has finished restarting.

Make sure the broadband cable (gray end) and filter are properly plugged in if you have a pink (or purple) light.

You should connect via an Ethernet cable to your desktop computer or laptop if you’re still not seeing an orange light. Next, try to get connected by opening a new web browser window and entering your hub’s default IP address.

My BT Home Hub shows a red light only. What should I do?

The red light on the hub may indicate a problem somewhere in the system which is not easy to diagnose without running through a few checks.

Again, we will need to restart the router and wait for it to power cycle. After around 3 minutes we should see that it completes its start up, and with a bit of luck, we should have a blue light.

Find a paperclip or a pin and then locate the factory reset button on the back of the device. You will see a very small hole, and inside that hole is a small push button. After the hub has completely rebooted into the default factory settings, it should work as normal within about five minutes. 

Keep in mind that this will set your modem back to its original state, so if you set up any WiFi passwords or if you have changed your login settings then you will need to have that information at hand before you undertake the factory reset.

Getting started: fixing BT broadband flashing pink errors Smart Home Appliances

Below are some quick and easy fixes for you to try before getting on the phone with BT. Hopefully you can get yourself back up and running quickly, which is a win in our book.

Let’s try reboot your BT Hub

A BT hub flashing is not fun, and sometimes means that your device needs a reboot. The simplest trick is often the most effective, and in this case a reboot is just that. Simply press the power button on your Hub, or unplug the power from the back and wait for a few seconds. 

Then switch the router back on or plug it back in and wait to see what happens, and if anything changes. If nothing changes then it might be time to check in with BT and find out if there are any problems in your area, or if you have a fault on your line.

Verify the status of BT Broadband in your area

In the event the LED does not show a connection, you should check whether your area has a problem.

It’s not easy to find out if BT is down in your area without an internet connection, but if you do have a smartphone, turn the WiFi off and check with mobile data.

Check out this link to the BT site for the current status in your area.

Try an Ethernet cable

Something to note is that many people report that their BT Hub is actually showing a blue light, but they are still unable to connect to the internet. If this is the case, then you might actually be dealing with a bad WiFi or DHCP configuration.

It’s also worth checking if you have a WiFi booster or other wireless equipment in your home. If so, then try disconnecting those units and restart your BT Hub again. If something was causing an error then this should clear it, and with some luck, you should be able to connect to the WiFi now.

If not, then you will need to connect an Ethernet cable to your BT Hub and then connect with a laptop or desktop. Once this is done, you need to login to the Hub admin page. There will be a sticker on the underside of the Hub displaying this log in information.

Press ENTER in your web browser’s address bar after typing in Provided that the factory settings of your BT Hub haven’t been changed, this should get you to the management page where you can either click on ‘Advanced’ (Smart Hub) or “Settings” for Hubs 3, 4 and 5.

Ensure your 2.4GHz and 5GHz Wi-Fi settings are enabled. In most cases, the two networks are merged together, so you can see only one name.

Have you tested the BT socket?

At this stage after ruling out all of the other factors in your home internet setup, it might be your BT wall socket causing the issue. This is highly unlikely though, and it is far more likely to be a phone extension cord if you are using one. If you can, try to get your hub close to that socket and plug it in directly to the wall socket.

Your router must be plugged into the master phone socket and not an extension to figure out whether it’s a socket issue or an extension cable problem. A filter is required if you just have one socket (if there’s only one, it’ll be shared between both the BT router and your landline phone).

Hub Factory Reset

A hub factory reset is usually a last resort solution to general problems such as a bad configuration, lost password, or a setting that you can’t change back. Simply locate the factory reset button on the back of the router and use a small object such as a paper clip to press it in for a a few seconds. This will reset your hub, and will take a few minutes to boot up again.

You must make sure that you have all of your WiFi passwords and account login details before you restore the factory settings of your hub. If you reset the hub and you don’t have any of these details then you will struggle to reconnect to it to perform configuration changes and setup steps.


If you’ve checked all of the easy fixes and your router is still flashing pink, then it might be worth checking with BT to see if there are any problems in your area. We hope that you have found this information helpful, and that your issue has been resolved.
