I'm looking for a good replacement of the leased comcast modem.

Is the leased unit just the modem or a modem/router?

If it’s just the modem, then you likely are going to need to keep it, since the ASUS unit is just a router.

I’m not the best guy to help on networking, I always get through it in spite of myself, but wanted to at least ask that basic question and get it out of the way.

It does not matter with routers. What matters is the "gateway" device - typically the "modem". Of course, these days, "residential gateway" devices are used. They are "integrated" network devices that have the router, the modem, a [typically 4-port] Ethernet switch, and a WAP (wireless access point) all in one box. These are 4 "discrete" or separate network devices that just happen to share a main circuit board, case and power supply. Some are 5-way and include VoIP (voice over IP) for Internet phone.

If you have a separate router and modem, only the modem needs to be compatible with your ISP. But if using a "residential gateway" device (because it includes the modem) it would have to be compatible with the ISP.

Note most ISPs maintain a list of compatible devices on their websites. You can find what is compatible with your Comcast/xfinity service here.

@rtwjunkie modem and router and switch and wireless of course.
@Bill_Bright thanks for clarifying my question, I have a 4 in 1 integrated discrete device. The gateway web portal doesn't give out the model but is one that looks like a beveled black mini tower, but yea I'll need one with wireless ac connectivity too. I don't want to enter my home address on their website cause then they'll know I'm looking for a replacement and may increase the price of my comcast bill. at least I know better what I need now.

doesn't look like the router I posted is any good, doesn't have gigabit ethernet and not even wireless n but wireless i? I was clueless I always look at router models and think it may work with my comcast to replace the gateway. I guess I'll have to call them.
