Elecrical interferece can cause this to happen, just like the fairy lights on Christamas trees do........yeah it's true
SNR can vary on an hour to hour basis, not is it affected by the speed of your connection but there are other things may reduce your SNR. Hot weather can cause a long line to expand. Wet weather on a connection somewhere could cause dampness and deteriorate the signal. Even street lighting and flashing xmas tree lights have been known to affect SNR.

Have a look on Kitz's site (http://www.kitz.co.uk/adsl/lowSNR.htm) her site is the best :thumbsup:

Yes, people think you are winding them up when mention the *fairy light and loss of connection* story. :)

I would certainly reccomend everyone to add her site to their favourites....she is a genius :thumbsup:

One of my hobbies is amateur radio and you'd be surprised at the crap that gets generated by electrical gadgets around the home. For example, a good, old fashioned, electromechanical bell generates radio signals right across the radio spectrum unless it's been supressed. The first radio transmitters were, basically, bells without clappers that just generated sparks.

Anything that switches a current can cause interference, and some of the cordless doorbells use radio frequencies that are easily picked up by the leads going in to routers / ADSL modems.

If it's a wired doorbell, see if there's anything you can do to move the any of the wires involved away from the ADSL equipment. You might try wrapping the phone wire from the ADSL Router through a ferrite ring - this will help reduce interference as well. If it's a wireless bell, you may have more difficulty in limiting interference, though the use of the ferrite rings on the phone wire might help.

Because ADSL is a broadband technology in communications terms, and the telephone cable used is not best designed to protect against external interference, ADSL is quite prone to generating interference as well as suffering from it.

Savannah comes up with top info as usual. Good site, that :)

Draggles low tech solution:
Disable the doorbell and get a door knocker.

Or keep half a brick by the door :hihi:

You didn't used to work at PCServiceCall or Freeserve tech support did you?

We had an interesting coupla weeks when some pound shops were selling dodgy fairy lights. The Freeswerve lot were coming down for smoke breaks looking confused, there'd been a big batch of people saying "my connection's gone, no it's back, no it's gone, no it's back". Took a while before someone twigged.

**edit - of course you didn't used to work there, it's probably before your time :hihi:

Is your door bell wireless?

Our door bell at work is wireless and so if my home alarm by remote. I changed the code on the doorbell at work to the same as my home alarm and now i can ring the doorbell with my remote - great fun watching people answer the door.

So maybe its on the same frequency if its wireless and your adsl router is wireless too.

this and security are the reason business' tend to use STP. can never have too much shielding.

when my dad had more time, he used to be mad keen on amature radio and had a inverted V 100meter long ariel from one end of the garden over the chimney pot and down to the other end og the garden which sent the neighbours TVs' bonkers for a while before he fitted filters gallore! "golf zero papa xray zulu calling CQ, CQ on 2 meters"
once you'd heard it a few times you could almost hear him saying it through the distortions of him speaking on the tv. strange how the carrier signal alone never affected anything........but then i know so little about it.

that's quite interesting, cheers chaps, might give it a look on the web. Never heard of it happening around here though...
