My dads ADSL connection is causing an audible buzz on his telephone line.

He is using Tiscali and the modem is a USB Speedtouch.

Any thoughts on what could be causing it please?

Sounds like a filtering problem. Are all the phones (irrespective of where the ADSL modem is plugged into) filtered? Try changing the filter that this particular phone is plugged into.

He's tried filters, he said all phones are filtered and in fact he's spoken to a company who specialises in them and tried a selection of high quality ones.

WEll if the filters are ok its either the modem is bjorked and is sending too low frequencies that the filter isn't filtering properly OR it's not the modem causing the buzzing. Are his phones wireless by any chance?

He does have one wireless phone but I'm 99% sure it happens on all phones.

Only started when he got ADSL of course... Wouldn't surprise me if it's the ADSL modem.. I use Cable tho so can't try mine :/

I had this problem and it turned out to be the microfilter was to close to a power socket and power converter 240v AC >12v DC moved it away and the buzzing stopped.

BT aren't any use :/

He said there doesn't appear to be any power adapters close to filters. His PC ones are 1m or so from the nearest.
Maybe to partially rule out a BT line fault, turn off and unplug the ADSL modem - see if the buzzing goes away.

Simply rebooting the PC causes it to go away ( until the PC has finished rebooting ).

usb modems generally don't sync until the pc has booted. Try with just one filter, one phone from the master if possible and see if the issue is still there. It's also worth trying from the test port under the faceplate of the master.
