<div dir="ltr"><div>I misread the wording on the filter in the dark. This morning I looked again and it says "QLP-1G", not "16". It also says "PPC" underneath, and a quick Google search leads me to believe that this is in fact a MoCA filter. I do not live in a "complex" but there are around 7 houses on my street. The interesting thing is that I believe that this problem may have gotten worse in early spring, which is about the same time I got new neighbors. The previous neighbors had satellite TV, not sure about internet. I will also say that I've noticed a speed reduction in my internet at times which I have also attributed to the neighbor (none of this is based on any facts of course).</div>
<div> </div><div>That said, this filter was installed prior to them moving in, so I don't think that was installed to resolve this and I haven't had Comcast out in over a year. I did have just internet service from them before adding TV as well last September.</div>
<div> </div><div>Just as another test, I removed the filter this morning to see what would happen to my signal. So now I have (just the path to my HDHR Prime) Comcast in -->Self Supplied Old Comcast Splitter -->40' Comcast installed coax cable --> Self Supplied Splitter --> HD Homerun Prime. I am seeing abotu the same signal strength as I was with the filter, at approximately -3 to -5.4 dBmV, depending on channel.</div>
<div> </div><div>My next test will be to reinstall the Motorola amplifier in place of splitter 1, but try to reduce the signal by using the Monster Cable splitter (-7.5dB/output) and the Comcast-supplied splitter (-3.5dB). If this isn't successful, I am going to send back the Motorola 2 Port amplifier (labeled "+11dB"), and replace it with a Motorola 4 port amplifier (labeled "+7dB"), and split the signal with splitters the same way.</div>
<div> </div><div>Also, yes, the amplifier is labeled "0dB" on the upstream side and it is supposed to be cable modem safe.</div></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Wed, Aug 28, 2013 at 9:47 AM, Gary Buhrmaster <span dir="ltr"><<a href="mailto:gary.buhrmaster@gmail.com" target="_blank">gary.buhrmaster@gmail.com</a>></span> wrote:<br>

</div>Another thought, especially if you live in a "complex" is that those<br>
could be MOCA filters to avoid interference between different<br>
residences. In that case, those are sometimes good things to<br>
have.<br>
