I've recently started MDWS logging again, run off my laptop. I noticed (if you go to Angel-Rex and select SNRm 5 days worth) that a pattern has emerged - my SNR dips from 6.3 to 5.8 each night around 9.15pm
Any suggestions what could cause this? I've looked at boiler timer and many other things - its not causing an issue, but it's interesting to see a pattern and if there is something electrical causing the 'blip'?
Thanks in advance.

It's a pretty common occurrence, you'll see iit on others as well. Street lighting could be one cause.

Like Ronski days that's very common. There's not likely to an electrical appliance causing it. Some lines move by over 1dB in a similar pattern to yours.

I'll suggest RFI, as a result of increased propagation through the ionosphere during the hours of darkness.
N*Star will be able to tell you about Radio China International (and Radio Romania) from first hand experience of their transmissions!

I thought it might be something similar, it's indeed getting dark around then.
I wasn't sure though, so best to check. It's not causing issues ATM, just wanted to check in case it looks suspect.
Appreciate the input :)

OK, my line just took a dive 20 mins ago and resynced at a much lower sync speed (was 42mb attain and now its 38mb). For the last 2 years my attain has been 42-44mb and always synced at a solid 40mb down 6mb up with 8ms ping. A big storm in May kinda killed this and I seemed to have been capped at 35mb :/
SNR on the DS is the same so i'm unsure why. the upstream SNR has gone up from 3db so I guess that was a bug?
It looks like there was a spike in errors, although nothing could have caused this - could this be DLM?
Could someone check over my stats and errors over the last few days and assist? Crosstalk? I've no idea how to check.
Many thanks again.
