@Daleb several possible causes but the number one suspect if you are streaming over a wifi connection is the wifi signal in your home but that would likely to affectvall apss not just the two you mention.
Streaming video needs sufficent bandwidth but just as important is stability. You may becablecto help by ensuringbthe hub and your streaming devicecare out in the open not hidden under or behind equipment and try powering down the hub for a few seconds so it reboots can help clear interference as it should choosecthe least congested wifi channel. However often you nedd a booster or similar to get a strongercsignal.
