I am sorry if this has been answered before but I could not find a post that relates to mine. I have been using both my Wifi and an Ethernet connection from my router for 4 months now (wifi to ps4 and phone, Ethernet to laptop). Recently, the Wifi is not turning on at all. I cannot find it on any of my devices and neither of the 2ghz and 5ghz lights are flashing anymore. I have tried restarting the router several times but it doesn't seem to make any difference. I have not seen any difference to my Ethernet connection since this has happened. I have occasionally used a plug in socket booster so that I could provide an Ethernet connection to my ps4 (located 8m from the router) but this has since stopped working too! I am not very proficient with computers and I'm sure there are easy fixes but any help would be much appreciated.
