we are facing issues with an ap mounted 15m high in ceiling in one of the warehouse. Model is 2700 E and checked the power level of both 2.4 and 5G, both are at high power since there are no near by aps. But still we are getting signal only from 5G but not 2G. Few scanners only support 2.4G and facing issues. Data rates are 1, 2, 5.5 disabled on 2.4G and rest enabled.
