Re: ADSL cutting out intermittently
Thanks for the reply! However I seem to have found the cause today. I tried using an AM radio to listen for any interference that could be causing it and have found one of our TVs causes a lot of it and only at times when the internet cannot sync.
We've had the TV for a couple of years with no problem, so I'm just going to have to work out whats happened to make it do this.
Thanks! |

| Well that's another new one!
I posted something here several months ago about lights interfering with the signal too. will it never cease?
There is probably a capacitor (suppressor) placed across the main feed in the TV that acts as a suppressor. if that has degraded or is/has failed, then it would have that effect. |

| Man this never ceases to amaze me - I have heard of all of the following being a factor:
- Washing machines
- TVs
- Arc welders
- Christmas lights
- Garage door openers
- Magnetic security doors (eg locks)
- Halogen and UV lights
etc etc
But in the real world I haven't actually seen any examples of people (and in particular helpdesks) actually finding this out for themselves..
Is there anyone that works on a helpdesk that knows of an easy way to spot things like this without asking the customer a million questions eg Do you have a washing machine, etc?
I have seen the whitelines on a 5530 analyzer (not sure if other helpdesks use this) and I have been trying to tie this to various frequencies (eg working out what frequency a halogen is at etc) but not having a heap of luck...
I also know a number of modems display the frequencies and their output - I think this might be used?
But Kudos to tobyw31 - nice detective work!
Cheers,
