Internet Dropout randomly - No Ranging response Recieved

Question

Last year in the summer we started having the internet drop out randomly a few times a day. Everything would reset and about 10 minutes later the internet would be back up for a few hours and then do it over and over again. Towards the night it would work fine depending on the temperature. All fall, winter and spring we have not had any outages in our internet.&nbsp;

It is now summer again. This is starting to happen again? I seen a few forum posts from customers of other cable companies that said they had a module that was overheating and resetting in the cable providers local box. I've called cox before and they were out here all last summer trying to troubleshoot this which it finally went away as the temperatures got cooler. Is there a way to get someone to check wherever all these connections come back into like a local cable box. I know some companies go to the end of a neighborhood street and then go back. I'm not sure how cox does it or how all it works. All i know is we have replaced everything in this house even bought the modem/router combo to basically prove a point that it isn't our modem and router causing the issues.&nbsp;

Now I'm really not sure if this matters but the way it sounds is this shouldn't be happening but this may be nothing. We also start getting more and more uncorrectables in the downstream channels. I just reset the modem so right now the numbers are low. The last column is the uncorrectables.

Hi Deitchman, I suggest we schedule a service call so an on-site technician can take a closer look. My team can schedule this for you, if you like. Email your full name, address, and a link to this page to cox.help@cox.com. You can also schedule a service call by calling 405-600-7676. -Becky, Cox Support Forums Moderator

I have the same problem although not as frequently as you, but it does happen.&nbsp; When it happens to me, I have to reset the modem/router to get connectivity again.&nbsp; I've had probably every tech from Cox out here, even a supervisor, who all promised the problem was fixed.&nbsp; Ha!&nbsp; It's just Cox's crappy equipment.&nbsp; I cannot even log into webmail.west anymore.&nbsp; I have to use the webmail.east server to get into my email.

Hi Rcook, if you continue to experience intermittent connectivity issues, I'd suggest that it's time for another service call. -Becky, Cox Support Forums Moderator

on my modem I have a new message
RNG-RSP CCAP Commanded Power in Excess of 6 dB Below the Value Corresponding to the Top of the DRW;

To add to this, Everything in this house, including the modem and the line from the house to the pole has been replaced. We bought cox's panoramic WIFI modem. Every cable in this house has been replaced.&nbsp;

I called Cox tonight to put in a request but there was an "outage" in our area and it won't let them put in tickets while there is an outage in the area? This has been happening for 3 years. Every summer it starts cutting out every 2-3 hours for about 10-15 minutes. As soon as winter begins and the temps begin to fall it works fine for 6 months. Then the temps rise again and now we are getting cut outs.......&nbsp;
