Constant ping jitter, occasional spurts of packet loss
I've done extensive testing of the ping jitter, and isolated it beyond my equipment. I am getting anywhere from 1-30ms round trip ping from my access point or router, but when I track my ping beyond my router, it has consistent spikes of ping up into the 130ms range.
This makes games unplayable.
On top of that, I have occasional disconnects where the connection lags like crazy for a minute every hour or so (sometimes more often, sometimes less). This only happens on upstream, as I can see that the UDP packets are reaching my computer, yet the packets leaving my computer are being dropped (no control over what's happening in game).
I have swapped my XB-6A modem with the Intel Puma chipset out for the XB-7T with the Broadcom chipset, and it hasn't fixed anything.
Then, I have tracked my upload power, and it seems to spike whenever the hourly disconnect strikes.
Outside of that, I have also swapped the splitter with a high quality Antronix unit, and then terminated all unterminated coax with 75 ohm terminators.
