Hello, I have a need to have a smaller WIFI network, specifically on the 2.4ghz band. This is for a Pet Tracking GPS collar. The Asus zenwifi 12 has such a huge coverage area the GPS collar picks up WIFI signal way far from my house, and that makes the collar report that the pet is home when its 2 blocks away. Since it uses 2.4 and the only thing I think I have that does, I was hoping to create a new WIFI network that had smaller range somehow. is that even a feature or thing that can be done and how?
