We have intermittent broadband problems in our household.
Isolation testing suggets it is not the phones etc in the house that are the problem.
I installed new filters but the problem still persists and I now suspect the modem. It frequently drops the ADSL.
The modem in question is a D-Link ADSL-502T (Gen 1), and I think about 5 years old.
Is there anyway to test its function, or should I just get a new one?
