Hi, So it still could be your WiFi especially if you have a router hooked up to your modem to provide it. I experienced something very similar last year and was surprised I did not get hit with a restrictions while it was happening. Ever since I made the changes everything is very stable with no issues. The problem you may be experiencing may be related to what bandwidth your WiFi is set. There is 20, 40 and 80 mHz. Most new modems will come set to 80 mHz which allows for fantastic speeds but will also have very high latency issues and lost packets. Games do not like that. Go in and change your WiFi to 20 mHz and your problems should go away, at least mine did. Even though my system was connected via hard wire, when other people in the house were using the WiFi it would cause connectivity issues with my modem and therefore my PS4. If that does not resolve your problem try changing the channel in which your WiFi is set because other electronics may be interfering with it. Most modems come set to auto. There are software programs that will allow you to monitor your WiFi channels for noise levels from a WiFi enabled laptop or computer. There are many tutorials online if you need help. Hope this helps, Guardian.
