Linksys AC1900 Cable shop Modem and Router

Product Name: Linksys AC1900 Cable shop Modem and Router
2-in-1 cable modem and router. Never used. Is not compatible with a landline phone. Only works with Spectrum or Xfinity provider. You might have to call your provider to activate the modem/router once you connect everything. I can open it up if anyone wants to look at the innards. It originally had a plastic film around it but it got sliced in half so I just took it off. (You can see in a photo the where it was sliced.) Long story short, I bought the wrong type of modem and lost the receipt so shop I couldn't return it. Since then its been sitting in my closet.
