A:AnswerMy house is 1500 sq ft but this router reaches into detached garage without any issues. I also have strong signal to end of my driveway. I am using with 3.0 Shentel so you should not have issues. Very well pleased with this.
A:AnswerSorry, can’t answer your question. Non-technical person here—called Asus customer service & tech walked me thru set up. You get a nice handbook & CD that any techie would love. You can browse their tutorials: https://www.asus.com/micro site/networks/tutorials
A:AnswerI have both routers in service at different locations. Operation and performance is the same between the two, with exception being the AC1900 supports Mesh Networks and has USB 3 ports, the RT-AC68U does not handle Mesh Networks and supports up to USB 2 speeds.
