I currently have a local Telco DSL modem that is connected to a ASUS AC3100 wireless dual band router and then also a NETGEAR repeater on another floor on my home. I am in the process of replacing the DSL modem with a AT&T velocity wireless internet device (MF923). The new velocity device will only broadcast 2.4 or 5.0 ghz but not both. Plus the overall distance is far less then what I have been getting with the ASUS router. My question is can I reconfigure the AC3100 to access the Velocity internet device? The Velocity device does NOT have Network cable ports so it will have to be a wireless connection. Or do I need to purchase another Netgear repeater?
Here we will be discussing a few simple steps to connect your Asus to an AT&T velocity device. The AT&T velocity hotspot can indeed function as a router for 8 devices on a given subnet. Devices can be recognized and connected for normal LAN and WAN operations, but only if connected to the subnet through DHCP. Static IP addresses are not supported and shall not connect. Follow the steps below.
For best wireless performance, make sure you only use channels 1,6, or 11 on 2.4 GHz with 20 MHz bandwidth. For 5GHz, ensure you're using an upper channel such as 161 with 40 MHz.
There is no need to purchase another Netgear repeater. Just, go through these steps to connect Asus router to at&t velocity connections -
