I'm using a NETGEAR N300 wifi router. Yesterday everything seemed fine, except for my wife's Ipad (but that's another issue). On a laptop running Windows 10 Home. Today I can get on my main IP site, at&t yahoo just fine (sort of), but I keep getting 404 error message everytime I try any site that isn't part of Yahoo. I apologize for being cryptic, I'm having to post this using my phone. Edit: I logged off of WiFi on my phone, and now the computer is letting me on TFP. I'm going to try some other sites.
