My first purchase of KL130 products were Hardware V1 when perform very well in my home network.  Several months later, I added two more KL130, but these were delivered as Hardware V2.  I've been experiencing huge latency differences, and unreliable connectivity with the Hardware V2 versions.

I setup a test with one lamp in a room with the V2 bulb.  From that location, I measured continuous ping times as:

64 bytes from 192.168.99.157: seq=536 ttl=254 time=93.953 ms
64 bytes from 192.168.99.157: seq=537 ttl=254 time=111.486 ms
64 bytes from 192.168.99.157: seq=538 ttl=254 time=22.590 ms
64 bytes from 192.168.99.157: seq=539 ttl=254 time=37.052 ms
64 bytes from 192.168.99.157: seq=540 ttl=254 time=47.165 ms
64 bytes from 192.168.99.157: seq=541 ttl=254 time=62.116 ms
64 bytes from 192.168.99.157: seq=542 ttl=254 time=76.279 ms
64 bytes from 192.168.99.157: seq=543 ttl=254 time=88.433 ms
64 bytes from 192.168.99.157: seq=544 ttl=254 time=111.619 ms
64 bytes from 192.168.99.157: seq=545 ttl=254 time=116.386 ms
64 bytes from 192.168.99.157: seq=546 ttl=254 time=29.277 ms
64 bytes from 192.168.99.157: seq=547 ttl=254 time=51.188 ms

Notice there is a "wave" in the times from a low of 22 ms to a high of 116 ms -- this patttern continues to repeat.

Next, I removed the V2 bulb and installed a V1 bulb and performed the same ping test:

There is a slight, and longer wavelength, "wave", but the latency is SIGNIFICANTLY lower.

Why is there such a difference between the two hardware versions?  The Hardware V2 bulb's WiFi connection also drops periodically every 24 hours.

Is this a known issue / difference, and are these any plans to investigate further and release a firmware update?
