Roku and HDMI switch with 5268AC

I was using an HDMI switch that toggled between my Nintendo system and my Roku 3  and DVD player before my getting ATT service and it worked well. After installation of my new ATT supplied modem/router (5268AC), the switch no longer works with my roku3. The Ninendo and DVD will still work going through the switch. Bypassing the switch and plugging the roku directly into my TV HDMI port allows the roku to work. I only have two ports on my TV and one is used for my UVerse connection. Any help to get my wireless ATT modem/router to allow my roku to use the switch would be appreciated. I'm also unsure which forum to post to, so please let me know if I have selected the wrong one. Thanks.

Re: Roku and HDMI switch with 5268AC

Did AT&T install anything between your Roku and the TV? If not, then it seems it shouldn't have any impact at all.

Have you tried swapping inputs on your switch? That is, swap the Roku and game system inputs and see if the Roku works and the game system doesn't?

Re: Roku and HDMI switch with 5268AC

I had switched the Nintendo and the Roku and the Roku still didn't work, but the Nintendo did. At your suggestion, I tried changing the DVD and Roku HDMIs and somehow that worked. All three inputs work now. If I had to guess, I'd have to say the switch had some priority sequence, but I can't be sure. Thanks for the help!
