No full fibre broadband since 28/03/25

[Jay20]

Will be grateful for any help regarding this. We are on talk talk full fibre 65 package. The internet has been patchy since 17th march but have no internet since 28th march. The router ( black wi fi hub sagecom fast 5464-2) is flashing amber at different speeds. The black ONT shows all 4 green lights. 
We have been on the phone to talk talk several times and we have tried turning off router, reseting it, talk talk has sent 2 routers(similar models, not sure why). We also had a city fibre engineer who checked things and advised it was a waste of his time when the ONT is functioning. 
we connected the ethernet cable from the ONT to our old laptop and it connects to the internet albeit at very slow speed. 
we are buying mobile data  in the meanwhile. 
any help will be appreciated

OK thanks. You appear to have an internet connection at the moment, are you still experiencing problems at your end?

Thanks Debbie. I had powered down the routers several times but never been advised to power down ONT. I will do both now and feedback.

Hi @Jay20 

I'm sorry to hear this.

Did you power down the router and ONT for a full 30 minutes? (this will start a new session)
