ethernet not working

i just installed windows on my new pc today and was trying to get ethernet to work so i can actually start using it. originally i used a cat6 100 ft cable from amazon and it didn’t work with my pc. it would work when i connected it from router to my laptop but not with the pc. i had tried uninstalling and reinstalling the driver/ disabling and enabling but that hasn’t worked. after fighting with this for a couple hours i went to micro center and picked up a better cat6 cable just in case and still no luck. my ethernet adapter is Intel ethernet controller I225-V. i’m not sure if maybe this is a problem with the driver/system itself or if the port on my motherboard (asus strix b-550 a gaming) is faulty as it doesn’t detect the cable at all. please help!!
