I recently unplugged my router for a while just to give it a reset and plugged it back in to the main socket on the wall where it is sitting and now my PlayStation isn’t picking up a WiFi connection to the internet or an Ethernet signal and won’t let me connect to the internet. I was literally connected before I unplugged it so I have no clue what is going on I’m picking up WiFi from my iPad and my phone but won’t let me connect to my PlayStation iv he nothing but bother with this router. Has anyone any clue on what this issue is and why this has happened I connected my phone threw hotspot to see if it would connect to my PlayStation and it did and it’s nothing to do with my isp as I have had them check my connection
