My adsl tiscali broadband cuts out when someone rings and also when hanging up.
It works fine all other times and I can reconnect when someone is using the phone also.
It is also not a clear phone line when you are using the internet while the phone is in use.
Any ideas ?
The easiest way to work it out I find is to remember that every phone must go through 1 filter - no more, no less, on there way to the main line.
So you could have just one filter at the main socket before any splits (but then you would need to run a long cable from your PC to the filter. so as Singh400 it might be more practical to have 3 upstairs and one downstairs.
