Hi, I just have a couple ideas.
Reset the router to its default configuration. This can be done by inserting something tiny like a paper clip end or pencil tip into a small hole labeled "reset" located on the back of the router. Press and hold down the small button inside until the lights on the front of the router blink off and then on again (usually about 10 seconds). If you donít know the router's default password, you can look it up HERE.
