There might be several cases in which a user has to restore the default settings of a Dlink router. Some cases are very frequent like - forgetting the login password, degradation in the performance level of the router, and forgetting the wireless credentials. The reset process can either be done manually or directly through the dlinkrouter.local interface. There might be several cases in which a user has to restore the default settings of a Dlink router.
