Hi, I have a Netgear DGN3500 wireless modem router that I'm trying to setup on my Dell desktop "Dimension C521". I get the error message "Ethernet adaptor required". I'm not sure why I am encountering the error message, as I have successfully installed a modem previously on the desktop via a ethernet cable.
An ethernet cable looks similar to a dial-up modem cable (phone line). Are you sure that's what you did previously?
