Flint 3 - Unacceptable Stability Issues, Where is the Fix?

And this affects at least 4 wireless devices : two phones, one tablet and TV (on separate only 5Ghz network), where Netflix does drops quality to lowest possible due to network instability.

So, does this issue seem to affect Wi-Fi clients only?

Have any instability been observed with wired clients?
