Bought for graft a Canon MS925 printer to a fax / modem that needs to stay connected to my ADSL router. Obviously a good enough quality, but apparently cohabitation between the two is not good, the line remains desperately silent after connection (over phone or modem and fax ... let alone the printer). The product I have momentarily on the arms, however, I think it is not defective, but this is the printer that "locks" something on the line. It may be able to use it one day.
