My ASUS Transformerbook says it's connected to wifi but I can't use any webpages or apps. I always get "This site cannot be reached". I've even tried using tethering, a hotspot, and a Linksys Wifi USB. I purchased this laptop a couple months ago and have had no issues, 2 days ago I downloaded an app and it downloaded Anti virus programs, it was working fine afterwards, it was just yesterday this problem started, I have deleted those programs. Any help would be absolutely amazing, thank you.
