So this is quite bizarre as I've never experienced this before. So on Sunday morning my WiFi was working fine then suddenly it just disappeared from every device that was using it over WiFi. My Phone, tablet and laptop all manage to find other nearby routers except mine. However I do have a PC that I use with an ethernet cable. For some reason that's showing up as an Unidentifed Network with No Internet Access. Currently I'm piggybacking off my phones data so I'm trying to be as conservative as possible but I can't find any sort of answer to this. I'm from the UK and use Sky Broadband and while it's not the best it's never completely broken like this. I'm not the WiFi owner and they're currently not even in this country so I've come here to see if I can get any help before ringing Sky as I know how difficult it's going to be without knowing the security checks. The even worse part is I'm almost certain it's there fault as I can connect to the router via ethernet and get the unknown network and all my router LED signals are showing green. Any suggestions are advice would be massively appreciated!
