Internet Issues

I have been fighting internet issues for a while now and have not been able to get any answers.

Internet will go down randomly sometimes for a few minutes, some times for most of a day.

If I chat in I am only told that I need a new modem (I actually replaced a modem to make a point but they really really really want me to pay monthly for that cox modem).

Here is what I am seeing on my modem.

  • The last time I posted about this I got a generic "please email cox support" message and they closed out my post.

  • I have a tech scheduled to come out tomorrow. This is a never ending cycle of untrained phone/chat support followed by equipment installers sent out as techs.

      I did notice that direct connection to one of my computers (not something that I can sustain for anything other than testing) worked a little better and I did not have so many errors. Then I noticed that IPV6 was enabled on my desktop but not on my router.. I enabled IPV6 and it has been more stable however it is still not good. Something is definitely wrong here.

        welcome to the club

        all these emails with countless pingplotter data, and still no fix.

  • I just had a tech leave my location.. He replaced the line from the pole to my house. He said that it tested good but he could see that it was old and probably was causing some issues.

    After the replacement my modem just booted up with similar power levels however there are no uncorrectable codewords in my modem.. I have never seen this before.. OFDM  still has a few but that should not cause an issue. I'll have to keep an eye on it.
