We have identified a problem with certain older wireless adapters (eg. Marvell AVASTAR 350N which is used in Microsoft Surface Pro 1 and 2) which prevents you from seeing AirServer as a Miracast destination when connected to the hotspot. This is a bug which is caused by a driver issue. As these adapters are no longer supported, this issue will likely not be fixed. It is however possible mirror p2p or mirror over infrastructure (same network connection)
