New EEOS router, red light showing when first plugged in

HappyGilmore — Sat, 19 Jul 2025 10:57:58 GMT

Just received the EERO 6 router after upgrading to 150, so first out of the box.

Followed the instructions, connected the fibre connection box to the EERO.

Then powering on fibre ONT followed by the EERO 6 it had a flashing white light for approx 5 mins.

After that just got the red light.

Anybody had similar issue and found resolution?

How far have you got in this how to guide?

https://community.talktalk.co.uk/t5/Articles/Setting-up-your-eero/ta-p/2760450

Have you downloaded the app to your phone for example?

If you can let us know how far you get in this set-up we may be able to help.

I'm assuming your fibre has gone live and your ONT box fitted by the engineer has all lights lit green, and that your old copper line is disconnected. If not you may be best phoning the Full Fibre Team to find out as staff here are unable to access full fibre systems at the moment.

However if it's just the set up, fellow customers may be able to help, so please let us know

Thanks for the link to setup instructions.

The ONT box was fitted a year ago and works fine with current router.

I have followed the instructions and the EERO app cannot find the device. If I try to add using serial number I get the message that “This eero is already registered, please have the previous owner remove it from their network”

So assuming it needs a reset.

Did you get this direct from TalkTalk or have you purchased it yourself?

Some Eeros are locked to providers networks. The TalkTalk ones are and registered to users.

You'd probably be best to contact the Full Fibre Helpdesk on: 0345 172 0074. Closed Sundays.

Please let us know how you get on

All you can try is a hard reset of that eero, but if as @fr8ys pointed out, if it is locked to another ISP, there is not much you can do.

I got in touch via txt with full fibre help desk and they got me to hard reset (button is not obvious) and now I can get the app to see it.

However it failed to connect to the internet, the help desk changed some setting on the ONT box but did not help. I’ll contact them again tomorrow.

thanks for all the suggestions.

Is your full fibre provided by CityFibre? If so, you will need a change of line profile.

You will need it on Profile T if it is CityFibre, Openreach do not use profiles.
