so i recently moved to the attic of our house (that is where my computer and the rest of my set up is). The attic is finished from the previous owner and i see that there is a outlet where i can put a coax in. i am thinking of moving the modem upstairs so i can connect via ethernet. i tried it last night but it wouldnt connect(i couldnt google anything after i connected to the ssid) i checked the beaker in the basement like other people have suggested in different forums and i see that a cable named "attic" is connected with multiple other cables. the problem is that the cable in the basement was colored white while the cable in the attic is colored black. also i was wondering if i can identify the wire by the string of numbers and letters on it. here are the photos that you guys might be interested in
