Hello AngelOfGod3 and welcome,
You should not have any issues using your Netgear 3000 Comcast Gateway (CG) with your asus rt-n66u connected into any of the CG LanPorts 1-4. The tc8305c modem is not a supported business class CG.
You might want to check out this link and provide your CG signaling information as described within for further assistance.
Hope this helps you out.
