But your SNR Margin is 16dB. What on earth are they looking at?
Good question. I have no idea. It's never done that before in all the time I've been monitoring my connection. It's happened on a couple of nights. The worst one being on the start of a weekend. Switching the modem off & leaving it off for 30 mins didn't make any difference nor did a quick re-boot. I had to wait until Monday when they optimised the line & that then brought the SNR back down to 6dB. They're still maintaining I have unacceptable background noise which is why my speed isn't increasing. I can see the errors but to me, they look fine. I'm still getting a huge spike in ES at night which I'd like to get to the bottom of. Not sure what those daytime one's are. I'm at work so they could be anything. Some days are OK & other days I get bigger random spikes of ES. All in all the total never looks that bad.
My full tally of errors for yesterday is below. I would say they're OK:
