Router intermittently flashing

Julessacha — Sat, 24 May 2025 08:34:35 GMT

Hi there,

my router light is going through the following sequence:

solid white for about 20 seconds then flashes white twice orange once white twice orange once white twice orange once white twice before going solid white again

I can’t see anything that says what this could be.

Internet connection seems all okay despite the flashing router.

Please can anyone help?

A blinking white light means the router is trying to connect to the internet If the light doesn't turn solid white after a few minutes, you may need to restart your router or contact TalkTalk for assistance.

Are the lights on the ONT green?

Hi,

The internet connection seems okay. The strange sequence of the lights on the router is what is concerning me. It isn’t the usual flashing lights when it is trying to connect.

Hi @Julessacha

If the internet is OK while this is happening, you could try a factory reset of the router. Press and hold the recessed reset button near the power button for about 10 seconds or until the light's colour changes. The reset will probably take about 3 to 5 minutes to complete, and you'll have no service during that time.

I’ve just tried the factory reset and it’s gone straight back into the same cycle of flashing lights again.

Internet is working. Green ONT lights are on as usual it’s just the flashing on the router.

I had an old router (exactly the same model) and connected that and exactly sequence of lights appeared once it connected to the internet!

I guess it’s not a router problem then.

I have also switched off the ONT and then powered back on but again this hasn’t changed anything.

ultimately the internet is working but clearly something isn’t quite right and maybe a wider issue

I just did a ‘Track my Fault’ from my account home page and got the following message however I don’t have any Digital Voice equipment:

Our tests have found a potential issue with the Digital Voice equipment in your home.

To resolve this, please perform a restart on your equipment including your router, eero and Digital Voice adapter (Grandstream ATA).

If you're not finding an improvement after performing a restart, please complete a factory reset on your Digital Voice adapter (ATA) and wait 15 minutes for it to resync with our network.

If you're still experiencing issues after this, you can chat to a member of our team using live chat for further help.

but as I say, we don’t have any Digital Voice equipment.

Hi @Julessacha

No ignore the Digital Voice thing at the moment, there is a wider issue with that. You said you turned the ONT off, but was it for a minimum of 30 minutes? If that does not solve the issue, you can try calling the Full Fibre Helpdesk on 0345 172 0074. Their opening hours are Monday - Saturday 08:00 to 21:00, Sundays 08:00 to 19:00.

Hi @Julessacha

Out of interest, do you have Digital Voice (VoIP)? I have just started noticing a similar light sequence on my router & I have no digital voice at the moment due to a current outage.

Re: Router intermittently flashing

Julessacha — Sat, 24 May 2025 14:16:26 GMT

Hi Keith,

I have Digital Voice on my account but chose not to utilise it. No equipment for Digital Voice is connected. I chose to use my mobile as my main phone.

Re: Router intermittently flashing

KeithFrench — Sat, 24 May 2025 14:24:27 GMT

Hi @Julessacha

Then, if Digital Voice is configured on your account, whether you choose to use it or not, this light flashing may all be down to whatever is the cause of the Digital Voice issue, as mine is flashing in a similar manner to yours. For the progress on that problem, see the Service Status Dashboard:-

https://community.talktalk.co.uk/t5/Service-Status-Dashboard/bd-p/service

If you log into the router, check how long the internet has been up for. This is found in the initial Dashboard, where it says Connection Up-time. If that is showing it has been up throughout the light flashing sequence, then the internet is remaining stable.

Hi Keith,

yes looks like the connection is stable. Whilst in the router dashboard I noticed it did say Voice is not registered, when it is.

Re: Router intermittently flashing

KeithFrench — Sat, 24 May 2025 15:15:15 GMT

Hi @Julessacha

You would also need a phone connected for it to register normally. However, it looks more & more like you are suffering from the same problem as me & others. Keep an eye on the Service Status Dashboard for updates.

I have exactly the same problem. I contacted talktalk through an online chat between 1200 and 1258 today and was told the following:

"I have double-checked everything for you and everything is working fine. Also, I've made a note of the details so that if you encounter any difficulties in the future, you won't have to repeat everything." and

"Sometimes the router network fluctuates, which is why it’s showing a flashing light. Please rest assured it will be automatically fixed."

"There's no need to worry about the light on the router it will return to normal shortly."

The lights are still flashing now at 16.52

I am completely confused by this DVA outage. A few years ago I replaced the eero 6 and grandstream DVA with a Sagemcom Fast 5464 router (used by TalkTalk themselves) I bought on eBay, as the eero doesn't have enough ethernet ports for all my devices. This has a built-in phone socket for an analogue phone. I do not need to use any DVA adapter. Normally when I power it on it blinks orange on and off until it gets an internet connection when it changes to a solid white. My analogue phone works fine with it.

For the last day or so the status light on it has been continually blinking white then blinking orange. My analogue phone is not working. There is a continuous solid tone on the line. Internet connection seems to be stable. Before I was aware of the DVA outage, I reconnected my eero and grandstream DVA. The eero status light was a solid white colour and there were no problems with the grandstream DVA. I got a good dial tone on my analogue phone and was able to make calls on it. Internet connection seemed stable.

Is there a DVA outage or not? And why is my router's status light continually flashing white then orange?

Gliwmaeden2 — Sat, 24 May 2025 17:03:15 GMT

It's not affecting everyone and they have not indicated any distinction between the Grandstream DVA and the Sagemcom method of using VOIP. So, hit and miss, @DrStrange.

@DrStrange

There isn't a "DVA" outage, there is a Digital Voice (VoIP) issue i.e. service, not equipment related.

Hi all,

Please look at the Service Status Dashboard. I have even put a sticky about it at the top of the Home Phone and Full Fibre boards.

Hi,

I also have the same problem.
