I have Unlimited Gold 30 plan which says I should have streaming at 720p. However, I'm not getting this when trying to stream YouTube or TwitchTV, it's buffering every 20 seconds. On ATT Speedtest I'm getting 38Mbps down and 4 Mbps up so speed seems to be fine. Are YouTube and Twitch getting throttled more than they should be or is there some other problem here? Problem exists on multiple devices and also with direct ethernet connection to modem.
