That's weird - it was active earlier on after my phone call to BT this afternoon and it was showing in dslstats as active. Only thing I can think of is that BT OR have reset the DLM again!

Same again last night ... FECs down from 200,000 to nearly zero from around 19:00 to 22:30 - is there anything that you have turned OFF at that time? Or maybe something that goes from idle to ON ... a PSU in an unloaded state could generate a lot of noise and as soon as it goes under load the noise disappears or changes? Or it could be filtering out noise from another device.

Hi! I didn't get chance to have a think about it last night but it's definitely weird isn't it?

Only thing off the top of my head that is on at that time and not others is the TV and Sky box. They are both about 10ft away from the modem. Perhaps I'll try powering them off at the wall later and check the graphs.

Could be worth trying ...

Power them OFF completely and even unplug them - leave for 30 minutes. Plug in and leave on standby for 30 minutes, then power up for 30 minutes. Start it on the hour or half hour so there is an easy reference.

You say 10feet - that is still close enough for RFI to cause problems and it could be radiated or conducted.

OK thanks for that. I'll give it a go.

Just s shot in the dark but but I have just remembered something. The router is in the corder of the lounge on the floor right against the skirting board. On top of the skirting board are some radiator pipes and on top of that are 2 old telephone extension cables from before we bought the house last year. They aren't connected at either end but the cores are bare and could be touching the copper pipes. I wonder if there is somehow some static in the pipes that is transferring to the cable ?? Is that possible?

Reason I ask is that the heating could be on at that time if the wife has put it on for the kids OR they could be having a bath too so the boiler would definitely be in use. The boiler itself was brand new in Jan so surely it would't be interference from that directly?

It looks too consistent for a bolier or heating related issue ... same time every night and not in the mornings. Although, if you have continual hot-water and only have the heating one for those few hours in the evening, then it might the valve controls ...

If your Sky & TV tests don't show anything, try putting the heating ON and see if that makes changes - or this eveing, have periods of CH & HW off, CH on, HW on and both off.

Yea I agree - way to consistent. Just looked back a few months. It's the same time each night. Even when we've been away too.

I'll do the SKY TV tests this eveing and report back tomorrow. Thanks for the help so far . . .

BT have an BT Engineer booked for me next Tues AM because of the difference in attainable (68583) and actual sync rate (57935) but it would be nice to get to the bottom of it on my own

It might even be worth turning off everything in the house including fridge, freezer, alarm and then unplug everything from the one ring which the hub/modem uses. Then power up that one ring and turn on the modem and a PC and see what that shows. Do it at a time when there are high error rates and see if it disappears - if it does, the problem is yours, if it does not then you need to consider neighbours or external.

Sounds like a good plan. Might have to wit until I can ship the kids/wife out for a few hrs on weekend though

I'll certainly still try the SKY/TV option later though.

I'm hoping it is my problem as at least if it is, I can do something about it. Obviously if it's external then I'm pretty much stuck!

Your lines been reset during the switch... meaning as your where G.INP before you've been dropped down to Interleaving with an 8ms delay on DS... G.INP should reappear on downstream soon.

I've found that any tiny changes now that are made seem to trigger this reset.... BT recently messed with my account whilst applying a disocunt this mean an order was gernarated fro my line to go from 80/20 to 80/20...

You'd think no changes would occure but my line reset as a result..... lost G.INP on my upstreas as a result **

Hopefully it wil be back next week though I'm currently having an IP Profile issue too, so unless that budges I think I'll be getting back on to wretched BT care.
