Without their help, I couldn’t get my wireless working properly.

Therefore, I decide to write this post to share my real-world experience. It will be update continuously.

Let’s begin from knowing my devices, network map, and placement:

Thecus W5000 and QNAP TS-119PII with Mac OSX Wireless File Transfer Performance Report
