Signal is intermittent and keeps dropping!

I only have Cox internet and I do not have a cable provider. I do not have a splitter and my router firmware is up to date.

What does this mean and how do I fix it? Please help!!!

These are timeout errors, which are times when the cable modem is having trouble communicating with us. They may be brief and not even noticeable depending on how many you experience. Looking at your modem history I am seeing quite a bit of them though. This is something that a technician will likely need to come out and diagnose. If you would like to setup an appointment you can email us at cox.help@cox.com with a link to this thread and your service address.
