A new internet tower was recently put up in my area and they’re coming to install it soon. They are going to run a satellite facing the tower and then a cable to the house with a modem I do believe. The modem will be in one part of the house where I cannot hardwire my computer and Xbox. I want to have the fastest speeds but I know hardwiring to the modem is the only way, I do believe. What exactly is an extender? Is there a way I can have the internet modem upstairs and then something plugged in downstairs and hardwire myself to that instead of the modem that is hooked to the satellite facing the internet tower? My computer has to be hardwired in order to be connected to the internet. Any help, or knowledge you can teach me would be great!
