I'm using an IPTV service on my Firetv 4K stick, and have 4 other friends who are doing the same. We all have our own IPTV accounts with the same provider, and are all using the same SmartersTV app, same version, on the same 4k Firetv sticks.

My service constantly buffers, and theirs do not. My internet speed is 60 down and 10 up. Some of theirs are substantially slower, even as low as 30 down. I've done speedtest tests at different times of the day, and while the buffering is happening, and the speed is always high, right around 60mbps. The Firetv is RIGHT beside the router, so signal strength is not the culprit either. I've tried both the 2.4GHz connection and the 5.0 connection.

The only variable between myself and my friends is that they all live in the same town about 20 minutes away and I live in a different down. But I don't live in the middle of no where, it's an established and perfectly fine city. Is it because they're using fiberoptic connections? My internet connection is cable. But nothing else freezes (4k streaming youtube, streaming Netflix HD, etc). I can literally be on the phone with them and say "go to channel XYZ and let me know what happens". They'll say it's perfectly fine, streaming smoothly, while when I'm watching at the same time at my house, it buffers every 5 seconds and is completely unwatchable.

I've cleared the cache. I've restarted the Firetv multiple times. I've restarted the router multiple times. I've spoken to my internet provider, they say it's nothing on their end, and I think I agree. This has been happening since I first got a Firetv and IPTV almost 2 months ago.

Why is only IPTV streaming buffering for me and none of my other 4 friends who are using the same service provider as me? Thanks.
