Hi all,
I occasionally get an error message from applications trying to access the
internet. It says "It appears you're not online" and won't finish whatever
task it was attempting. This happened most recently with the Windows Live
apps but has happened with others.
This is on a home pc connected to the internet through a 5 port router and a
DSL modem. I am always connected. When I get this error I am still able to
load my browser (IE7) and access the net and the other PC's in the house.
Any idea's or help would be great.
