Looks like the gain is 10.2-11 dB. <a href="http://www.motorolasolutions.com/web/Business/Products/Cable%20Broadband/RF%20Amplifiers/BDA100/_Documents/staticfile/BDA_Catalog_Specifications.pdf" target="_blank">http://www.motorolasolutions.com/web/Business/Products/Cable%20Broadband/RF%20Amplifiers/BDA100/_Documents/staticfile/BDA_Catalog_Specifications.pdf</a><br>

I have a Sonicwall firewall and a separate Meraki access point (also both connected to the switch). My frontend has another switch connected (also a TrendNET), but that is upstairs. For what it's worth, my brand new frontend does act laggy at times with fast forward and loading the recordings screen but this is fairly rare.<br>

Some recordings will be perfect, others will have pixelation periodically, others will have heavy pixelation, yet others will be so bad that the recordings stop during playback. The same channel will not behave the same twice--sometimes things are fine, other times they are terrible. This seems to happen on any channel and do not occur at any particular time of the day or during any other operations or recordings on my network.<br>

<p dir="ltr">Okay, so your signal strength is at a negative. If you amplify that you are amplifying a poor signal. I suspect If you hooked the HDHR directly to your splitter #1 this value would be in the positive. </p>
<p dir="ltr">FYI: a perfect reference signal is 0.0 dBmV. You want to keep your signal as close to the reference as possible. If you go too high you can get the same kind of problems. Most digital devices consider values between -12 and +16 dBmV as acceptable.</p>
<p dir="ltr">If you do not feel comfortable replacing splitter #1 with your amp, then I believe you would get the most value placing the amp directly after it. Then run any additional splitters off the amp.</p></blockquote>
<div><br></div><div>This makes perfect sense. I think I am going to put the amplifier in place of the first splitter installed by Comcast. It is currently outside but I can easily bring it inside. </div><div><br></div><div>
Oddly enough my signal is now showing:<span></span></div><table style="width:inherit"><tbody><tr><td style="text-align:center"><font><span style="line-height:normal;background-color:rgba(255,255,255,0)">Signal Strength</span></font></td>
<td><font><span style="line-height:normal;background-color:rgba(255,255,255,0)">100% (-0.5 dBmV)</span></font></td></tr><tr><td style="text-align:center"><font><span style="line-height:normal;background-color:rgba(255,255,255,0)">Signal Quality</span></font></td>
<td><font><span style="line-height:normal;background-color:rgba(255,255,255,0)">100% (36.8 dB)<br></span></font></td></tr><tr></tr></tbody></table>Which really seems to lend credibility to my "intermittent" description.
