How to fix Nexus 7 screen flickering issue?

Oh no, my Google Nexus 7 has screen flickering issue. Guess that I am one of the lucky guys out there who face this Nexus 7 screen flickering issue. Actually, it is Nexus 7 display screen backlight that has issue. And this Nexus 7 screen flickering issue only happens when you have poor Wi-Fi signal (with active upload or download activities) and display brightness lower than 30%. I can easily see this issue because my old Wi-Fi router is still at IEEE 802.11g only (802.11n have better coverage range).
