Hi, I'm usually very lucky to have a stable 500 meg service and, but in the last week or so it has been really erratic. The online tool says everything is fine and I really struggled to make myself understood to tech support on the phone. I'm in Bushey, near Watford, Herts. I've spoken to some of my neighbours who have said they've started having the same thing around the last few days, but have all had no joy with tech support. I've rebooted the Superhub again just now and have noticed there are pre RS errors.

The logs show this:
