I updated my router to the Google Nest a few days ago based on recommendations from friends and online. Ever since, the audio/video is out of sync on my tv. I stream using my Roku, have an LV tv and Vizio sound bar. I did troubleshooting with LG, even reset the tv and the problem persists. I didn't have the issue with my prior router. This is extremely frustrating. I unplugged the point that was near the tv, thinking that would help.
Reading the posts, this appears to be an ongoing issue. I'm ready to return the router and go with another brand.
Thanks for reaching out and I'm sorry to hear that you're having an issue with your Nest Wifi. To isolate the issue, could you try setting your TV as a priority device? You could click on this link to learn more about this.
