YouTube and other Streaming Buffering a lot since about 4 days ago

As the question states. About 4 days ago, youtube and I noticed other streaming services buffering a lot. Play a few seconds, buffer, play a few seconds, buffer, over and over. However, i've also noticed some like cbs all access not buffering.

Now my other computers (3 others) in the house are not having this issue.

Not sure what's going on given my speed tests are: 844 down and 841 up mbps.
