<p>This feels like a classic three party finger pointing exercise, and I'm doing a bit of research before we jump in. </p>
<p>A couple of years ago, our church put in a sophisticated (at least by MY Measure) Ubiquity Unifi Mesh network, mostly to support security camera for the community pre-school. </p>
<p>The core is a UDM Pro router, feeding all Ubiquiti stuff. </p>
<p>And it has run totally steady. </p>
<p>Here's the rub: Now that the "Last Guy That Touched it" moved to Florida, I'm getting multiple alerts per day to the effect of:</p>
<ul>
<li><span style="color: #50565e; font-size: 14px; font-family: 'UI Sans', Lato, Arial, sans-serif; background-color: rgba(33, 35, 39, 0.02);">Your primary internet </span><span style="color: #50565e; font-size: 14px; font-family: 'UI Sans', Lato, Arial, sans-serif; background-color: rgba(33, 35, 39, 0.02);">Comcast Business</span><span style="color: #50565e; font-size: 14px; font-family: 'UI Sans', Lato, Arial, sans-serif; background-color: rgba(33, 35, 39, 0.02);"> was disconnected and has been restored multiple times in last 24h. If this persists, please try restarting your ISP Modem.</span></li>
<li><span style="color: #50565e; font-size: 14px; font-family: 'UI Sans', Lato, Arial, sans-serif; background-color: rgba(33, 35, 39, 0.02);"><span style="font-family: 'UI Sans', Lato, Arial, sans-serif;">Primary internet is experiencing high latency. Please restart the modem or contact the ISP if this persists.</span></span></li>
</ul>
<p><span style="color: #50565e; font-size: 14px; font-family: 'UI Sans', Lato, Arial, sans-serif; background-color: rgba(33, 35, 39, 0.02);"><span style="font-family: 'UI Sans', Lato, Arial, sans-serif;">Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaand, nobody complains. Occasionally, I will see Zoom meetings from home where the church participants go really fuzzy and blocky, like Zoom has downshifted their resolution. </span></span></p>
<p><span style="color: #50565e; font-size: 14px; font-family: 'UI Sans', Lato, Arial, sans-serif; background-color: rgba(33, 35, 39, 0.02);"><span style="font-family: 'UI Sans', Lato, Arial, sans-serif;">Apparently it measures ping time to Ping.UI.Com to decide this. </span></span></p>
<p><span style="color: #50565e; font-size: 14px; font-family: 'UI Sans', Lato, Arial, sans-serif; background-color: rgba(33, 35, 39, 0.02);"><span style="font-family: 'UI Sans', Lato, Arial, sans-serif;">The Unifi Console reports the Comcast Business router as providing typical 14ms latency. With the occasional spike to 45ms. </span></span></p>
<p><span style="color: #50565e; font-size: 14px; font-family: 'UI Sans', Lato, Arial, sans-serif; background-color: rgba(33, 35, 39, 0.02);"><span style="font-family: 'UI Sans', Lato, Arial, sans-serif;"><img src="cid:18f032338fd29c5b49147846d2855457@mnopltd.com" /></span></span></p>
<p>When I ping that address from my Uverse internet from home, I'm seeing consistently results from 7ms to 10ms. </p>
<p>I don't know whether to ask Ubiquiti about raising their thresholds, or Nag Comcast about their performance. I guess I could ask Ubiquiti precisely what does "Internet Disconnected" mean? </p>
<p>My personal experience with Business Comcast in the past has been....... not impressive. Usually, a service call just makes it worse. Is Comcast going to take my report from Ubiquiti seriously? Or tell me to pound sand? What additional evidence need I present?</p>
<p>Yes, I could spend a quality hour in the furnace room, with a notebook connected to the LAN side of the Comcast router, (the only way I can talk to it) and see what I can see.</p>
<p>I suppose I could just call Comcast, and give up another hour of my life to try and talk to someone with a clue. </p>
