A:AnswerHi, CD,
The Linksys E5400 is a dual-band router that provides better speed, range, and security for all your networking needs, so you may use both bands at the same time. You'll be able to stream HD videos, surf, email, play online games, browse, and chat efficiently at AC1200 speeds.
A:AnswerHi, Annie. As long as you have a modem that supports Ethernet connection and has active internet connection with Centurylink then it should work with the Linksys E5400 router.
A:AnswerIf your Comcast modem has a “gateway” the router is in it already. This product is more for creating a Lan type ring or old school modem to router setup.

A:AnswerApparently, at least 50. That's the default limit in the configuration. However, the more active devices connected to any router, the slower they will all be.
