I recinetly replaced my old router with a new R8000 and reconnected my Uverse receiver and tv. Now Uverse will play for about one second and lose connectivity. Does anybody know why?? If I remove the R8000 and wire direct to the Uverse receiver it work fine. I have always ran my cat 6 through the router and have never had any problems with the routers, must be a setting in the R8000 I'm missing??
I appologize if you already tried this... but a quick search on google yielded a few results that might be helpful. If these dont work, please post your full list of iptable rules from ssh.
