Recently, as of 4 months ago I have had an issue with my PlayStation 4 (original) and my wifi. It seems as if everytime I turn on the PlayStation every device in my home using the WiFi, their connection is bad and very very slow. I use a TP-Link extender as well as a TP-Link router. I've asked PS Support and they sent me to their online help, but that gave me no help at all. I have tried switching the channels in my router website, as well as a wired connection. Someone also suggested that I place the PS4 further away as well as closer to the router and see if that helps, which it did not change anything. My PS4 worked at another home prior to this, but I have not been able to check it at another house with a different router type to check if it was the PS4 or my router. I have a local ISP that is only known in my area so most probably won't know who it is. Any help would be appreciated.
