I believe the last power cut was maybe 10 years ago, possibly even longer than that. There's no timers in my house, let alone plugged in, so I'm absolutely certain it's nothing on a timer. I will try the SuperHub 5 on another socket, with the use of an extension and report back. That's a good suggestion worth investigating. If nothing else, it would help to rule out the power in the house. I'm thinking of trying to power the SuperHub from a power bank, but I don't think there's any suitable adapters that would let me do this. That would definitely help to rule out power in my house as well as the SuperHub's PSU. Re: Flashing red light on SH5, but internet appears to work Just posting as a continuation and to confirm that this red light issue is still ongoing. Last night, during normal use, the red light flashed for no apparent reason. Again, nothing was shown at this time in the network log - basically, as though nothing had happened. I am beginning to notice that odd time the red light does flash, is late evening, from around 10pm until midnight. Re: Flashing red light on SH5, but internet appears to work Yes, I've powered the SH5 on and off a few times recently. I have another engineer coming out in a few days, so perhaps I'll know more shortly. Flashing red light on SH5, but internet appears to work I've had an issue with my SuperHub 5 for a few weeks now. If I restart the SH5, it will go through the startup process as normal (flashing white light, turning to steady after 2-3 minutes), but it now flashes a red light for about a minute after starting up. Recognising the red light wasn't good, I contacted Virgin Media broadband support, who sent an engineer out who replaced the wiring and splitters inside my house But after all that work, the engineer still got a flashing red light, so they decided to replace my old SH5 and it's power supply with a new one from their van. After registering the new SH5, it too showed a flashing light. I should add that while the engineer was testing, only the power cable and coax cable was connected to the SH5. My phone line and ethernet devices were disconnected throughout testing and when the flashing red light reared it's ugly head. The engineer left my premises saying they've done all they can and that my signal levels look good. But to be honest, I wasn't best pleased about lack of explanation. As far as they were concerned, my internet was working and the flashing red light was just a niggle I'd have to live with. Tonight (two weeks later), the red light started flashing without any apparent cause. The network logs didn't show any messages at same time this happened. I will do my best to post my the SH5 stats as it currently stands. Perhaps somebody might spot something that I could sign post the next engineer to.

Thanks for posting, Matthew_ML. No I spoke to the team about something else. I still remain confused and bewildered. How do I change passwords for the main and secondary accounts? I am very confused here. I want to change the password for my main email account and it's associated secondary accounts. When I click Virgin Media Mail settings from the Account settings page, I am asked taken to a Mailbox App password management page. Okay so Virgin Media have changed something to something I don't understand and I don't know what this Mailbox App is. On the same page there is a Generate new App password button - but for what app? I am bit old school and use MailWasher Pro to check my accounts for email and delete spam accordingly. I then use Pegasus Mail as my email client for my Virgin Media accounts and store my emails locally. I don't want to generate a new app password in case it locks my main and secondary accounts, rendering them useless. Especially when I don't have an app to enter the new app password. I just want to change the passwords for my main and secondary accounts as a security practice. What is all this about an mailbox app, where do I download it and how I did change my passwords in it?
