I physically added a second wireless router to my Comcast home network with an ethernet cable connecting them. The second router works fine as a second wireless network and as an ethernet switch to which I added my TV, Apple TV and Stereo to the network. The problem is, I can not access the router settings or see it on my network. I never installed the CD (program) for this second non-comcast, Netgear router on my new Desktop Computer. The Netgear router was previously programmed on the previous Desktop, which is no loneger on my home network. Therefore, the WAP password was already programmed. My question is, will it mess up anything on my network to now install the new router's CD (programming) on the new Desktop Computer? Are there any settings to which I neet to pay particular attention?
