I'm typing on my wife's machine because my machine has not had internet access all day, no matter what I've tried. It's only partial though. HTTP (Chrome and Firefox), Skype Dropbox, MYOB and steam do not work. Email, FTP and TeamViewer do. Can't think what else.
Googling led me to something I know nothing about (netsh int ip reset) but still no joy. Have no idea what could be doing it - have lost most of the day and still no further on. Any suggestions more than gratefully received.
