    @Tradev, Do you have any splitters or signal amps on the cable line going to the modem? -Allan, Cox Support Forums Moderator.

        Tradev, can you send the information you have showing the timeouts? - Lisa, Cox Support Forums Moderator.

    The T3 timeout is your real problem. A DRW violation is a momentary glitch, but a T3 timeout is a complete loss of upstream connectivity. You should focus on the T3 timeouts not the DRW violations. If you follow all the instructions given by the Cox representatives and the problem continues you will need a Cox tech to troubleshoot the issue.
