Any luck with tech support? I have basically the same issue. Only Wifi-mPCIE-Card in G module is working flawlessly, module A wifi wasn’t detected. So I opened the box and realized that both antennas were disconnected and cables in position that it was obvious that they weren’t connected during Mox assembly. After connection I managed system to detect module A wifi card and it was working until I tried to assemble plastic box after wich wifi stopped working again. I repeated disassembly and assembly multiple times but haven’t managed to make it work in assembled state. There must be really something wrong in wifi card connection to A module.
