So I changed internet providers and my new 2 in 1 modem/router has a Coax cable for internet unlike my older one which used an ADSL. I tried 2 different Coax ports in my house while on the phone with my ISP and they could not activate my equipment. The modem/router was just scanning for downstream channels for a good 15 minutes. They said they will send a tech but it will be $40-$50. I want to see if my condo's junction box has an unplugged cable to my room. Furthermore, if there is no problem with the cable in the junction box, what would the technician actually do to allow internet access through my coax cable? Would I need a new cable, strip some wiring from my wall, etc?
