You won't get any form of staff giving updates on here in relation to broadband. It has never happened in my time of using the forum.
Below are some standard things you can and probably have done before calling the team.
Have you done a factory reset to the router indicated in the link below?https://help.nowtv.com/article/improve-broadband-speed
This link also shows any planned outages as well wide spread faults.
You need to call the broadband team. See link for number.
Is this the WiFi, or the Internet that issue cutting out?
The two are very different things, and it's important to understand this when trouble shooting
If it's WiFi, then your devices will not connect or will drop the connection
if Internet then the WiFi will be fine, and you will be able to connect to the WiFi network, and other devices on the network, not the wider internet
@Jacjacou said ‘The light in the middle keeping going off then orange and flashing’. Which if it’s not a faulty router (and I don’t know why Now sending a replacement counts as ‘not being helpful’), is a line fault that @Jacjacou should report to Now, so that they can get Openreach to investigate it and address it.
