I'm looking for an Android TV box under 100 dollars that of course supports kodi. The Chinese variants are okay. my only exception is that it must support 4k and 4x4 mimo. The Amazon fire TV stick 4k is only 2x2 mimo and only gives me about 150mbps of my 400mbps internet. Ethernet adapters are not applicable in my situation. Any suggestion of any Android TV boxes without Ethernet adapters that can take full advantage of my 400mbps internet?
