A:Answer The AC2600 is an actual router system allowing you to connect one node to your modem while also connecting a device with cat5/Ethernet cable. This one node should cover up to 1,500 sq ft. Adding the second node allows up to another 1,500 sq ft coverage...so YES, this AC2600 (which has 2 nodes) should cover your 2,000 sq ft single story house. Again, this IS a Wi-Fi router system so no need to purchase another router; only need a modem & ISP.
