W8901G is ADSL router while Archer C7 and C2 are typical wireless router without ADSL modem. Can you explain what kind of ISP do you have?

First you need to know that Archer C7 has 6 antennas in which 3 are of 2.4GHz and 3 are of 5GHz,2.4GHz antennas are internal antenna and 5GHz antenna and the external antenna and the 5GHz antennas are of 5dBi so that the external antenna will give you good range like 100meters and 2.4GHz antenna are also give you good range it think above 50meter.

And another thing you need to know that Archer C7 dosen't have ADSL port.So if your ISP in giving you ADSL connection so you need something that converts your ADSL connection to RJ45 port

I know it, and I want to buy a wireless router because I think wireless routers provide better results than ADSL wireless modems.
I just want to know how is Archer C2 wireless coverage

Hard to answer such kind of questions since it is largely affected by network environment. What's your expected coverage?

A 23 meters range including walls. for a 400 m[SUP]2[/SUP] two story building.
I read good things about WR842ND and better about WDR3600 range in amazon reviews.

My second question. Can you explain what kind of ISP do you have?

I use ADSL. I heard having separate router and modem is better than a modem/router.

So you know that ADSL line needs modem or router with modem?
