Contents: Main unit, power adapter, LAN cable, instruction manual, repeater WN-AC1167EXP I purchased this several years ago and used it at home, but I am selling it because I upgraded to a new model. It is a used item and has some dirt and scratches. It was working normally until I removed it. It has been initialized. Thank you for your understanding.
