Flashing lights on new router

[JohnC61]

I've recently upgraded to Full Fibre & supplied with a new modem to accommodate the landline connection.

For the first week, the light remained white.

However, every 23 seconds (yes, I timed it) it cycles through 2 white, 1 orange flashes, 3 times, then goes back to solid white. 

I've tried both turning off/on & the 30 seconds reset with no success.

I should point out that my broadband connection doesn't seem to be experiencing any problems but the continual flashing is a concern.

Hi John,

How are you getting on, have you tried switching the ONT and router off for at least 30 minutes as Keith advised?

It is not 30 seconds that you need to power things off for, with full fibre you need to power both the ONT & the router off for at least 30 minutes. If that does not change things, do a factory reset of the router's configuration. Try that & if still the same I will ask TalkTalk to investigate it for you.
