Lost 4Mbps on the downstream on my 50Mbps typical connection today.

I had to resync at sunset unfortunately. Around 5pm in winter, not ideal. I normally always sync between 6am and 11am. And my sync is usually pretty consistent.

Would a sunset sync really make me loose 10% of my downstream speed?

Thanks

It's really difficult to say, for certain, without having a significant archive of back-statistics to consider.

However, could it be feasible? A tentative "yes" would be my response.

Thank you

My concern was centred around the fact the previous modem location was 1 floor above the master socket on the end of an in-wall extension. It had been syncing and stable on this.

I went to the master socket, removed the extension wiring, fitted a new filtered faceplate and plugged direction into the master socket, no wiring needed, did not mess with the master socket wiring at all. Same modem, same RJ11 cable but now no extension, didn't even bother punching it into the extension posts on the faceplate, so I'd expected the sync speed to improve or at least stay the same.


SNR Margin wise. Purely based on my usual morning syncs, it tends to stay stable between 6 and 6.3 in the morning. In the evening I have noticed in the past it will hope between 5.5 and 6.3. Definitely seems more volatile, just don't know how much that impacts an evening sync.

There is a very simple question that needs to be asked . . . If you had not looked at the statistics, would you have noticed the change in synchronisation speed (as manifested by a change in throughput speed)?

Give it a few days and see how it goes. If it does not improve (or gets worse) then we will need to do some investigation.

Yes that’s right I probably wouldn’t have noticed if I hadn’t looked. And even though I know I’m unlikely to notice in my usage.

Just a shame, was actually hoping for improvement.

I might try a switch off for 1 hour tomorrow and then a sync and see what happens.

Just to update

The filtered faceplate for some reason was causing a 2Mbps loss

The additional loss is being caused by home plugs.

The SNR Margin fluctuations are pretty big with these plugged in.

6.4 typical, 4.9 floor. With regular drops to 5.4.

All home plugs removed and the SNR Margin is a solid 6.4 all day. The most is moves is 6.2 to 6.5.


Home plugs are obviously a bit distributive to vdsl signals!

Thank you for the update.

Hmm . . . Clearly there is something wrong with that SSFP.

The additional loss is being caused by home plugs.

I consider them to be evil devices.

I agree
