Hello Harrison,
There can be several explanations, but the main thing we should keep in mind that different apps have different requirements and use the resources available differently. To make an example, obsolete drivers might cause no issues for game X, but high latency in game Y. A certain app running in background can cause no troubles with Z but end up “competing” for resources with K, and so on. A prolonged freeze like the one you experienced can also indicate a performance-related issue, rather than a connectivity one.
If you are still experiencing issues, please check the following support article:
We also tried to answer the most common questions related to connectivity in this post. I hope you’ll find it an interesting read!
