One channel wasn’t coming in but all the others were. On calling them they went through the usual rigamarole (power cycle the cable, box, the TV and check all the coax connections). I was incensed again noting it was only one channel having an issue. I said if it was a connection issue it would affect more than that one.<br><br>Finally, I checked the coax connections just to make them get off that idea. The one on the back of the cable TV box was fine. However, as soon as I touched the end of the one at the wall jack it fell on the floor. That wall jack was on the wall nearest the exterior breezeway and it had been years since I initially connected the cable to it. My guess is that it was vibrations caused by people walking through that breezeway over the years that caused it to unscrew. <br><br>After reseating the cable at the wall jack and screwing it back into place the one channel that had been an issue began working. I’ve often told people since then I hate it when THEY are right. </span><span style='font-size:11.0pt;font-family:"Segoe UI Emoji",sans-serif'>😊</span><span style='font-size:11.0pt'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>From:</span></b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'> Ale <ale-bounces@ale.org> <b>On Behalf Of </b>Neal Rhodes via Ale<br><b>Sent:</b> Saturday, September 6, 2025 4:05 PM<br><b>To:</b> Atlanta Linux Enthusiasts <ale@ale.org><br><b>Cc:</b> neal@mnopltd.com<br><b>Subject:</b> Re: [ale] So, Comcast says 8-16ms to their first hop is...
