I think I finally fixed the buffering issue I was having on my Amazon Fire TV. I changed the Wifi network setting to 5 GHz from 2.4 GHz on my ARRIS SURFboard SBG6700AC, and what a difference it has made. No more blurry and fuzzy TV shows!!!! In addition to changing to 5 GHz, I also changed the channel bandwidth to 40 MHz. So far, I haven't had any buffering issues and my internet download speed on both Fire TVs are between 125-137 mbps, increased from 40-50 mbps. I pray my Fire TV continue to be buffer free.....only time will tell! I hope this information will help those who are having issues with buffering on their Fire TV.
Thanks, glad to hear it's running much smoother for you. I'm still experiencing sporadic buffering issues, but it's not as bad as before. I reached out to customer service and I was told they are working on an update to correct the buffering issues. Hopefully they'll have this problem fixed within the very near future.
I definitely feel your pain. I had to play around with the channels in order to get some relief from the buffering. I noticed in the mornings and late at night the buffering seems to quiet down; however, during the evening hours (3-9p) the buffering is intolerable. Hopefully DTVN will fix this issue ASAP!
