Internet drops intermittenly

Question

This started on Thursday, October 26, 2023. The internet will drop intermittenly and then come back. This is very disruptive for working from home which I do 100% of the time. According to the cable modem logs, this is what I'm seeing:

All the phone and chat support personnel want to do is reset yourr cable modem, which DOES NOT work. Why all off a sudden this issue is happening and when will COX fix the issue? I've never had previous issues since the beginning of 2023.

Any help would be appreciated. I have Motorola MG8702 cable modem.

Thank you!!

I'd like to follow up after the technician service call. The technician was able to locate and fix the issue and so far my internet has been solid. The issue was the wiring in the main pain that feeds the line to my house. Once he corrected the connection there everything was good again.

We can mark this thread - solved or closed.

Thank you everyone for your replies!!

I'm Sorry DannyS but it seems to me we compare notes here trying to figure out what the problem may be.&nbsp; I have the same problem as bassplayer and finally have the time to pursue the issue to find an answer.&nbsp; For example my wifi drops intermittently no rhyme or reason and reboots also at the same time we can't control the contour box, I assume this should point to some issue.&nbsp; I recently installed a Panoramic Wifi to update my equipment but my older system didn't have the same issue.&nbsp; Open to suggestions, TX Tomzee

tomzee · Answer

I did follow your advise DannyS and spent 0ver 30 minutes on chat only to have it drop out because my internet went out! An I did it again to get no results, the folks want to know if your wires are hooked up and reset your gateway regardless of the fact I am chatting with them. As what is listed at the intro to the forum:The Cox Support Forum is where customers can collaborate with each other to resolve issues they may be experiencing.Sorry bassplayer223 I'm sure you had the same result.

bassplayer223 · Answer

Tomzee,No worries.&nbsp; Yes, I had the same result.&nbsp; I went ahead and scheduled a technician to visit to see what's going on with the lines outside of my house.&nbsp; I read another similiar thread that a neighbor had installed outdated wiring or a device that was causing the same issues at the hub.&nbsp; My setup is easy.&nbsp; Line from house straight to cable modem box.&nbsp; No MoCA devices or anything complicated.&nbsp; Simple hookup.So far, the service dropped twice on me today during meetings, of course. :)Thanks for the replies!!&nbsp;
