Internet goes down when cablecard and tuning adapter are connected

I have been running HDHomerun Prime with a Cox cable card and Cox Tuning Adapter successfully for years. Suddenly my internet and phone went out. After hours of trouble shooting I swapped the Cox Panaromic modem, cable splitter, and all coax and ethernet cables out and still no internet. I found if I remove the HomeRun and Tuning Adapter from the system my internet and phone work. I then swapped the tuning adapter with the same issue.  At Cox request, I put in a new Vecima tuning adapter a month ago and all worked well. I have made no other changes to my system other than Cox downgraded the speed of my internet just before the problem started. Could Cox have made another change that causes this? I am at a loss on how to determine if it is the Cox Tuning Adapter, Cox Cable Card, or my Prime. Any suggestion are welcomed. Thanks.

    Salubrius, thanks for posting in Forums for Community assistance. I am sorry you're having issues with your set up. If you only remove the HomeRun, does everything else work as it should?

      Negative. With only the HomeRun removed from the system I have no internet or phone. With all new cables and splitter, everything points to the tuning adapter. It is a Vecima. At Cox request on a working system, I replaced my old tuning adapter with a Vecima a few month back and all worked well. When the current problem started after replacing everything else but the cable card, Cox sent me another Vecima tuning adapter but it does not help.

        I am sorry that did not help. We can see about scheduling a technician out to the home. Please send us an email to Cox.Help@Cox.Com with your full name, address and link to this forum for assistance.
