I have C7. Frankly, I expected more from AC router. I have it in AP mode (my modem has a built-in router). The wireless is OK (but not overwhelming). I have AC laptop and Samsung phone with AC support - yes, it's better than N devices. But it feels that N devices get worse bandwidth than from the modem/router that is in a worse location. On top of everything it loses wireless connection occasionally (sometimes once in a few days; sometimes once a month) - and the only way is to turn it off and then back on again.
