since the install is that I can't get the internet on the desktop.
G'day
Binos. I had a similar problem some time back - I must have checked every lead and cable into and out of all the boxes and jack points probably 3 or 4 times.
In the end, I called my provider and asked him wtf was wrong.
He suggested setting up a new connection ie. go to Control Panel, Network and Internet connection, set up or change your Internet connection - and re-enter all the info...password, account name, etc. Hey presto
Good Luck!
