I do not know the specific range, but and TP Link W8968 300mbps transfer rates are the same as the Huawei E5186 4G LTE router that is I'm using a router. My house is 3 floors and I use a E5186 which is placed on my main floor. It gives me complete coverage throughout the first floor and basement as well as backyard. We are able to stream on multiple devices from my NAS sitting in the basement.
