Premise: This FAQ assumes your networking functioned properly and unexpectedly the client fails to communicate, out of the blue. You've established that your Internet is up from the device displaying the problem and you can reach the WCG forum and can log into the My Grid page. General: Any action taken on the client to force communications with the project servers will try to open a link and keep it open for 5 minutes, even if in the Activity menu was set to Network Activity Suspended or the Preferences were set to network according a time limited schedule.
