    Thank again Furry. Based on the logs and information in the links you provided it would appear that the problem is NOT related to the modem itself. Cox is implying that the problem is the modem as per DOCSIS tips, T3 timeouts are typically caused by noise on the upstream.

    What a nightmare dealing with Cox.

     

    It will be interesting to see the difference with Panoramic WiFi that we should receive within a couple of days. I feel like we are being taken agvantage of and forced to sign up for something we should not be replacing.

      We received Cox Panoramic hardware and I hate to say... it is flawless.

       

      I do not like this solution because now I have to sell both my modem and router. That is so frustrating.
