A test network configuration is captured. A test network signature is generated from the test network configuration. A label is assigned to the test network signature. A determination is made as to whether the test network signature is labeled as an unsuccessful network signature. If the test network signature is labeled unsuccessful, one or more procedures to change the label are generated. ## Claims ### Claim 1 A computer-implemented method for diagnosing a network configuration of a computing device, comprising: capturing a test network configuration;
