About every 10th to 20th time I attempt connect to the internet I get a "No Connection Can Be Found" message. I normally have my wireless connection and 2 or 3 more sensed in the neighborhood. When I go to "Connect To", no connections are shown.
To connect, I have to turn the computer off and then back on. Turning the computer off and back on always allows me to connect to the internet and when I check for available connections, all the normally available sources are there.
