Please help. My son can't connect to PSN from his PS4 or if he can it disconnects after about 5 minutes. I tried to log in to the PSN account on the laptop and again it wouldn't work. However, I can log in to the PSN account on mobile network which would suggests a possible problem with PlusNet? This has been ongoing for the last 2 weeks. Spent ages trawling internet for a solution but still no progress. Any help or suggestions would be welcome.
