    Looks like ingress in the 900Mhz range, probably from cellular. Have you bypassed all the spitters in the house?

    Hello ChandlerAZ85224,

    I am so sorry to hear that you are experiencing intermittent interruptions in your service. That would be very frustrating. We want you to have service that you can rely on. When experiencing signal issues, the first step should be to check the connections within the home to make sure that nothing has changed that could interfere with the signal getting to the modem/gateway. When you have a chance, can you go through the steps below to ensure everything between the connections is secured?

    Check the connections to ensure they are all secured and the cables are undamaged.
    If you are using a splitter, bypass it by connecting the coaxial cable directly from the wall outlet to the modem.
    If you are using an amplifier in the home, check that it is secured and the light is lit to the AC adapter.
    Make a wired connection by plugging an Ethernet cable directly from the modem/Gateway to the device.
    Reboot the modem/Gateway by unplugging the power for 30 seconds and reconnecting it.
    If the issue continues after these steps, can you email my team at cox.help@cox.com with your name, address, and a link to this thread?

      I did the checks and still have the issue.  Looks to be getting worse:

    I have the same issue with my connection being normal and then random going out completely or just poor. I’ve talked to the support on here but it’s still been a week. Working from home this week has been a challenge at times.
