We should write up a document of possible causes of freezing
Some possible causes that will do that are....
Downloading or uploading Torrents will do that.
Using a Ytube Downloader tool will do that.
Using a gaming console on-line will do that.
Your PC taking an automatic Update could do that.
ISP traffic or other ISP issues could do that.
A bad wifi connect will do that.
An overheated power-line adapter would do that.
A bad ethernet connect will do that.
Those are just some non-technical reasons.
Check what you can Hank.
I do not assume to know the more technical possible reasons.
There can be 100 different reasons and the server is included as a possible reason too. The Server is never ruled out for possible cause..
That is why it is good to get feedback, as members here will give.
