We can attempt to push a firmware update to see if this will help, though V6.01.07 is approved by Cox. If issues arise after attempting a firmware push, then you may need to perform a factory reset to your Cable Modem. Do you have a signal amplifier attached to the coaxial cable or is there a splitter or barrel attached to the cable?
I have the same issue regardless of connection (hardwired, or router) and I do not have a VPN. I'm convinced the issue is on Cox's end. Something in the neighborhood needs to be replaced or updated, or somebody connecting to the same node is using up all the bandwidth. I don't want to go through the hassle of having a tech come out constantly to say everything is "running perfect" when it's clearly not and they are aware of it. I'm not a tech wizard, but I'm at least smart enough to know how to troubleshoot my own equipment to see if it's faulty.
We’d like to get more information about the performance of your modem, please log in with your primary Cox User ID and run the Internet Tools Speed Test: http://bit.ly/2lxbIS9. Please run the test twice; once with your modem connected directly to your PC or laptop with all background software closed, and once with your modem connected to your router in their normal configuration. We can use this data to further investigate what is happening.
