So I have just bought a PS4. I am having issues with it being able to sign into psn or download the software update 3.15. My signal strength with my wifi is 100% & both my internet along with IP address are successful when completing a connection test. When I go to do the software update it tells me of a time out error every time. I have tried downloading the update in rest mode. My roomate has a PS4 as well & it works fine. I didn't know if multiple devices could cause a connection problem either. Considering with my own PS4, my roomates PS4, 4 phones, two laptops & a tablet are connected. I'm using the Arris Xfinity TG862 modem if that can tell you anything. Please help, thank you.
