Hello, My new MBP No Touch have this problem. I bought new 32GB sandisk ultra 3.0 flash drive and use adapter to plug in to type-c port. Here is the problem, the flash drive detected and have no problem transfer file with no error, the problem is Wi-Fi instantly drop out after i plug the USB3.0 flash drive. I try use 2.0 flash drive, have no problem transfer file and the Wi-Fi working fine. I try charging my MBP and plug in 3.0 flash drive, The Wi-Fi working fine. Anyone have this problem, and my router running 2.4ghz mode.
