ANy electric alarm clocks going off at 6?

What in the heating system causes interference I suffered a 11db drop in noise margin this morning(good job my snr is set to 15db ATM)so no drop out, thing is the boiler and switch are around 6m away from the router/socket can the interference spread that far?heating now permanently switched on lol

Any of the electrical items of the heating system can cause interference, such as flue fan, pump or motorised valves.

How come it only seams to happen when switching on or off

Timeswitch?

Thermostats have been found to cause problems see the link below, on heating or hot water startup the motorised valves (if fitted) open and the motors on these can also cause interference.

Hence the reason have told my mrs to leave the heating on 24/7 and just turn the radiator down and up when we need it

Even so, the boiler will shut down from time to time, as will the pump.

so what is the best way to rectifie this is there a way to block out the interferance,or is it a case of not having it on

The first thing is to establish whether it is causing a problem. Do you have a battery-powered MW radio?

I have walked around but can't find any bad interference,there is a plug socket next to the master socket which sounds a bit funky when the radio is next to it.will a shielded twisted cable rj11 help?

I didn't have time to check this morning. I got up early so thought I'd be a loser and get in work early and clear some work

I did notice last night that the upstream noise was up to 12?! I have no idea why it's behaving like this. I even turned the outside security light off to see if that made a difference, but it didn't. I knew it wouldn't ad that's been there for ages with no I'll effects.

We've got nothing on timer at home and nothing comes on or is switched on at 6am. It's s total mystery

I wouldn't be surprised if there's still a fault on the line, which is magnifying something that's always been there. I guess I'll never know unless the line completely deteriorates again and I'm forced to spend months dealing with muppets from BT again.

It may not be a problem in your home, but one that shares the electricity phase with you.

Niall · Sep 20, 2011, 14:18:58

Say what now?

Den · Sep 20, 2011, 14:25:52

Try unpluging the fridge and the freezer they are often the cause of spikes and have greater cappacitors than the boiler controls.

Simon · Sep 20, 2011, 14:33:54

Not permanently, though.

It certainly won't hinder, and could well work.

Niall · Sep 20, 2011, 15:32:26

Our freezer is (trapped) in the garage. I may have let the wind slam the garage door shut, which ripped it off it's hinges. In my defence the counter weights had broken so there was nothing to stop it going at the speed of light. Those doors weigh a tonne with no counter weights I can tell you! Currently waiting for a new one

Anyway, there is nothing in the house that could cause this as I went through everything during the last 4 months of problems. I've run out of things to check!

Niall · Sep 20, 2011, 17:44:04

Ah cr*p, noise margin up and down is 12 now, and I've lost another 2mb while I've been in work

Niall · Sep 20, 2011, 17:47:22

Is there anything I can tweak in my 7800n that could possibly improve things?

Smashing it to pieces might make you feel better for a second but I can't help much more than that.

The DLM is obviously seeing something on your line and increasing your default noise margin to give a more stable (in theory) connection. If things remain stable for 2 weeks plus, then the noise margin may decrease again.

Niall · Sep 23, 2011, 17:33:21

Sure enough, noise has increased by 3 every 2-3 days. I'm now back up to 15db and my line has lost 3mb in speed overnight.

Yet ANOTHER engineer will have to come out. I'm wondering if I need to sue someone to get this sorted properly. It's a bloody piss take now.

Niall · Sep 23, 2011, 17:42:07

Oh goody, the webmail isn't working properly either. How fun.
