Mag254 Streams Freezing But Audio Still Playing

On my Mag254 (less than a week old), I'll be watching a stream on IKS66 server and randomly the stream will freeze video-wise. Meaning I can still hear the audio playing as if no freezing ever happened. The only way I can fix it is to unplug the power cord and plug it back in. Is there any fix to stop this freezing? I've already updated my box (and have it on auto-update). Usually when people say freezing, they mean buffering. I do get buffering (but that could be from a plethora of reasons honestly) but it usually just happens at night time which just happens to be when network traffic is at it's highest in my area.
