I have been using 2 IPTV services...and local channels buffers and skips. I have tried a VPN, that made no difference. I clear Cache off my Amazon Cube daily, it has at least 60% Free space...I re-Boot Modem and Router. My Internet Service is 400/20. Perhaps this is a global issue with Local channels with IPTV services. I can select a different Cities channel for the same network....and channel plays fine....but doing so I won't be viewing my local News. I am seeking a recommendation from users who use these services that tune the major USA Networks (NBC\CBS\ABC)...and have had no buffering issues.
