Before calling I ran a status check (all OK) and changed my Virginmedia password on the off-chance. 403, as usual. Call to 150 wasn't as bad as I feared. I spent about 10 minutes on the phone including 'in a queue' time. Email is now working. The advisor had to 'send a help to my router'! Make of that what you will. I asked if a reboot would have fixed the issue - answer = no. So, it seems the only known way to fix this is to call 150 and have a 'help' sent to your router too! I warned the advisor that I'm just the tip of the proverbial and to expect many more calls....
