First, thanks for taking a minute to read this. Question, does the Galaxy tab Pro 12.2 tablet support the 5mhz band on ac routers? I've been told yes and no.
Welcome to the forum, The specs say it has support for Wi-FiĀ® Dual-Band 802.11 a/b/g/n/ac which indicates that it does support 5 GHz (not mhz)
