Weird stuff going on with the PlusNet Hub One router and one of my Playstation 4's on WiFi When only this one PS4 was on, my normally 20Mbps/15Mbps fibre would slow down on every computer in the house, to 3.19Mbps/0.64Mbps with 125ms ping! I tracked it down to this one PS4 and noticed it was getting a really bad Wifi signal so I plugged it in on a CAT5 wired cable and it fixed it. The PS4 was saying the router was NAT Type 2 (Moderate security) and didn't support packet fragmentation. (I have uPnP disable on the router to improve security). This PS4 was located in a home extension so the signal was traveling through a brick and breeze block external wall, so yeah that explain the PS4 having a slow internet... ...but the wierd thing is why would a slow Wifi signal on that one PS4 slow down the internet for every device in the whole house? Is there a bug in the PlusNet Hub One router using up all it's CPU power when trying to maintain a bad Wifi connection? This could explain a lot of speed complaints!
