If that router you got from your Internet company is not providing you Wi-Fi throughout your whole house this is the answer. This ASUS router has a long range over 1700'. With the extendere they solve any problems you may have of reaching the yard or the corners of your house. My house is a little bigger and I try to use these but ended up having to get a mesh wireless router so I am selling these for people who need better WI fi coverage and a smaller house of up to 1700 ft². I was using them with Spectrum, just plug them into the modem and they pretty much do everything for you. The extenders you plug into an outlet and extend the range of your Wi-Fi.
