Hi,
Very grateful for any advice on whether there's a fix for the below or if I need to request an engineer (which will take 4 days, currently...)! From the logs, it looks like it's struggling to lock downstream/upstream channels.
There was scheduled maintenance in my area today, following which the Virgin website and phone line both now report no issues. However, although the TV is fine, the router keeps cycling through a reboot and then ends up with a solid green light and flashing green arrows.
Downstream

Thanks for the reply, John. I've managed to solve it without an engineer! I spoke to the technical team on the phone, who suggested that whatever work had been done might have lowered the signal to a level where the router wasn't able to lock channels. They suggested I remove a 6dB attenuator that was added on installation and, instantly, this fixed the problem and everything is working fine now.
