Constant ping jitter, occasional spurts of packet loss

Hi,

 

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.

Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

Upload does peak occasionally, I will post it once it peaks.

Re: Constant ping jitter, occasional spurts of packet loss

The downstream is on the high side, The SNR's and the upstream were ok at that snapshot in time.
