Here’s how to fix PS4 slow WiFi speed issues and problems that you maybe having in 2017 when using your console at home. Sony is in the luxury position of having one of the world’s most popular video-game platforms in the PlayStation 4.
Hello To All:I just upgraded my internet speed to 150/150 with Verizon Fios, last Friday. Speed Test, via ethernet is upper 140s down and low 150s up on my Verizon modem. The boys had an old Netgear router and their speed tests were significantly slower than what the main modem/router was putting out.
I decided to upgrade to a Netgear AC1200. Setup was easy enough, the speed tests on the boys computers concurred with what I was getting from the main modem/router.An issue has occurred whereby one of my boys is getting kicked off of gaming, NBA2016, at the end of games. When we did an internet connection test, via the PS4, he is getting 145mps upload and less than 10mps download. Do you feel it is something within the PS4 or could it be the fact that I changed the router?
He states that he has never been kicked off of a game before. Is it possible that PS4 is unable to handle the faster internet speed? Thanks in advance.
If any applications are running, the PS4 appears to change the settings for PSN store downloads, artificially restricting their speed. Closing the other applications will remove the limit. There are a few important details:- Just leaving the other applications running in the background will not help. The exact same limit is applied whether the download progress bar is in the foreground or not.- Putting the PS4 into rest mode might or might not help, depending on your system settings.- The artificial limit applies only to the PSN store downloads. It does not affect e.g.
The built-in speedtest. This is why the speedtest might report much higher speeds than the actual downloads, even though both are delivered from the same CDN servers.- Not all applications are equal; most of them will cause the connections to slow down by up to a factor of 5. Some games will cause a difference of about a factor of 100. Some games will start off with the factor of 5, and then migrate to the factor of 100 once you leave the start menu and start playing.- The above limits are artificial. In addition to that, actively playing a game can cause game downloads to slow down. This appears to be due to a genuine lack of CPU resources (with the game understandably having top priority).So if you're seeing slow downloads, just closing all the running applications might be worth a shot. (But it's obviously not guaranteed to help.
There are other causes for slow downloads as well, this will just remove one potential bottleneck). To close the running applications, you'll need to long-press the PS button on the controller, and then select 'Close applications' from the menu.The PS4 doesn't make it very obvious exactly what programs are running. For games, the interaction model is that opening a new game closes the previously running one.
This is not how other apps work; they remain in the background indefinitely until you explicitly close them.And it's gets worse than that. If your PS4 is configured to suspend any running apps when put to rest mode, you can seemingly power on the machine into a clean state, and still have a hidden background app that's causing the OS to limit your PSN download speeds.This might explain some of the superstitions about this on the Internet. There are people who swear that putting the machine to rest mode helps with speeds, others who say it does nothing. Or how after every firmware update people will report increased download speeds. Odds are that nothing actually changed in the firmware; it's just that those people had done their first full reboot in a while, and finally had a system without a background app running. No, the issue is that the OS is artificially kneecapping its network connection to PSN servers whenever anything is running, apparently out of a wildly over conservative desire to avoid starving any other game or app of resources (which makes sense on paper, but a 7K receive window cap is absurdly silly).Edit: to be clear, it's 100% an OS software issue, 100% fixable simply by changing whatever code in the UI reacts to application launches by choosing to clamp the network socket's receive window to the size of a thimble. Only a local proxy would improve speeds, remote proxies would not.
The issue is that the PS4 varies a parameter that defines how much data it will accept until the server (or the proxy if one is used) will have to wait for an acknowledgment that the data actually was received.Putting a proxy on the same network means that the ACK will be received without much latency and that will speed things up. If it goes through your internet connection to some other proxy it will likely create the same issue as directly using the CDN.For users the easiest way will likely be to close all Apps and if that doesn't help to do a full reboot to get to regular download speeds.Overall the speed limiting seems to be intentional (going by the article) and the way it is controlled by the OS is a pretty weak implementation.

They would have to adapt it at least so that the limit only kicks in when the foreground application or game actually needs the network (to stream video or play online) instead of doing it always regardless of what's happening.
