You Still need your AT&T modem, as its a modem, a router and a wireless access-point at the same time, build in a "cost effective" way to suit the average user. This on the other hand ASUS is a High End Gaming Wireless router, best in class for what it does, but its not a modem, so long story short you still need your AT&T modem that will connect to this Wireless Router. But your wireless experience will be night and day, specially with new devices, or you had coverage issues. Once you install the New Router, it would be best if you disable the WiFi from your modem, a) so you dont have your devices confused on what network to connect, and b) to have the less wireless signals in your environment fighting the spectrum. This will help your new router work better as well, as there will be less contamination in your wireless spectrum. no need for those signals you are not using. Additionally, and (not necessary) for more advanced users you know a little of what they are doing, you should also go in to your AT&T modem SETTINGS -> FIREWALL -> FIREWALL APPLICATION, PINHOLES AND DMZ, and put your "new" router in the DMZ and forward all the ports to the new router. On my particular modem the option is called "DMZPlus mode". Do a speed test before and after the upgrade so you can see the difference.
Sorry, there was a problem. Please try again later.You'll still need to use your modem. This is just a router.
Sorry, there was a problem. Please try again later.I apologize for those claiming you absolutely need a modem. That is very dependent on what your internet access point is. If your internet enters your house on RJ45 you absolutely do not need a stand alone modem. If it enters as a phone line or coax (cable) line, then yes you do. I run this as a modem/router with 1gig fiber. The switch is done by the ISP outside my house and delivered into my house on RJ45 ports.
