No data traffic can pass from one side of the router to the other, or data is intermittently getting corrupted when passed through the router. Thoroughly check the software and hardware configuration of the router. If in an Ethernet and TCP/IP addressing environment, check for the correct TCP/IP address. Attempt an ICMP ping test. Are any incorrect configuration parameters present in the router? Take the necessary action to resolve the problem and retest the router for proper operation. If the failure symptom is gone, record the problem in the network maintenance and service log. If the problem still exists after retesting, go to the next step. Attempt to run router diagnostics. Did running the diagnostics produce any errors that identify a router failure ? Take the necessary action to resolve the problem and retest the router for proper operation. If the failure symptom is gone, record the problem in the network maintenance and service log. If the problem still exists after retesting, go to the next step. A problem with the router may still exist, but to get more conclusive fault-isolation data perform a protocol analysis . If after peformning the protocol analysis, you cannot conclusively locate the problem, and you continue to find failure symptoms that point to a router problem, refer to the manufacturer's instructions.
