My main 46 inch tv is connected to NVidia Shield. It buffers about once every minute. My other smaller tv (20"?) with a Firestick doesn't buffer. I put them both on the same channel. Main tv is directly connected to my modem. Firestick is wifi. Makes no sense to me. Any suggestions?
Get yourself a Formuler z8 And that buffering will stop! Nothing better for IPTV than the Z8!
Is the shield much older? Could it just be “worn down” If you restart it do you have better performance for a short time?
I know you will experience buffering if you are using more devices than what you get. If your iptv provider sold you one device and you are trying to use 2 devices at once it'll buffer.
When all else fails, factory reset.
