Examples relate to determining access point power output. In one example, a computing device may: identify, for a particular access point, a plurality of neighboring access points; identify, for each neighboring access point, a pathloss value that indicates a difference in a transmit power of the neighboring access point and a received signal strength observed by the particular access point; identify, from the neighboring access points, at least one adjacent access point, each adjacent access point having a pathloss value that is less than a pathloss threshold; generate a representative pathloss using the pathloss values of each adjacent access point; determine a target power level for the representative pathloss; and provide at least one of the neighboring access points with instructions that cause the at least one neighboring access point to adjust a power output level of the at least one neighboring access point.
