I have my VZ router which is connected to my old PC in my office, which is upstairs. My laptop sits in the kitchen (wirelessly) downstairs. My question is, what would I need to buy to be able to make the laptop a wired connection (to get the true internet speed on the laptop that I pay for). Is that what a wifi repeater/extender with ports is for? If so, is there a certain type/model/specs that are required for it to work? Thank you.
