Hi guys
Our treadmill is located at the far end of the house and in a room without a phone extension. At speeds above 6km/hr however it increasingly interferes with our ADSL connection to the point that from 9km/hr the modem does not find sync and connection is not restored until the treadmill stops.
I've tried 3 different ADSL2+ modems, with different filter/spitters without there being any noticable difference found between choices. Running the modem on a UPS that's disconnected from the mains (so purely running on battery) does improve things however, so it appears the noise is in the mains power rather than induced in the phone line. ADSL while on that battery can still drop, but it's a big improvement, and it tends to be able to reconnect. My UPS is too small to run the treadmill on, so I've not been able to try that (but am keeping an eye out for something to suit).
From what limited information I've found, treadmills can be a nasty source of electrical interference. And it would appear I've got a live example. Is there anything I can do to modify the treadmill to reduce this? I recently pulled a food processor apart and found a capacitor across the mains - is this something that could help, and if so how do I calculate the right value to reduce the interference that kills ADSL2+? Or if that's not the answer, what can you suggest I try?
Thanks
Geoff
