I have had this problem ever since I formatted my computer. I thought it was a mistake so I formatted it again, but came to the same problem. I can almost always connect to the network because I have managed to set it up, but even when connected I get the same message. Sometimes, though, I do get disconnected for a few seconds and then reconnected. On some occasions I have to reboot to regain access to the connection. Can someone help me solve this please?
