New Router wont connect - flashing blue light

RossP — Mon, 20 Apr 2026 08:20:38 GMT

Received new eero 6 pro router after account upgrade last week. Still waiting on whole home WiFi device to arrive.

However have tried connecting new router to internet. Should have been east and straight forward.

But router wont connect, only blue light flashing on it, and nothing further.

Any suggestions ?

Thanks.

Are you on Full Fibre provided by CityFibre? If so, you need to contact the Full Fibre Helpdesk & request that you be put on the CityFibre line profile T. Otherwise, an eero will not be able to connect.

They can be contacted on:-

0345 172 0074.

Their opening hours are Monday-Friday 09:00 to 19:00, Saturday 09:00 to 18:00, Sunday: Closed.

If you encounter a bot, then, after the bot, you should be transferred to an agent. You may not always be able to speak to someone on this number; they may send you a text message instead. If that is the case, the text will contain a link to start an online chat. On that chat, you can insist on speaking to a person, but there may be a delay before you are connected.

No, I am not on cityfibre. My connection is via BT openreach. The connection box is not the problem. It's the new router from Talk talk which is the issue.

I am sorry, but as a customer myself, I had no idea who provided your fibre. This will require TalkTalk to deal with your problem.

It won't connect just by plugging in.

You have to connect via an app on your phone.

There should have been instructions in the box
