I purchased the high performance flat panel near the end of last year to replace my original residential rectangular antenna. Yesterday I completed the swap of the antenna and cable and added the power supply, but I did not replace my original router/wifi module. Is this a requirement? Everything appears to be working, but I just want to be sure this this is not a contractual or functional requirement that is going to affect me or the system down the road ... like when I go to sell or transfer either the old or new system.
