Darn,
Ok then. Are you using default settings or have you configured the router for custom settings?
Sometimes it's best to just start with a clean slate, factory reset and configure the router to your needs again. Once you have done this, I recommend going to Tools/System and do the Save Configuration to file. This will save what you have set up for future use and should you have to do a factory reset again, do it, then load the Config file to save you time.
