I have a desktop that I built a while ago. Fastforward to last year and I had to put in a wireless card to connect to my internet at my house I was living in because the landlord wouldn't let me connect a cat 5 cable through the attic. anyway, I've used the computer with a wired connection without problem. Anyway, my new place has a wired connection for me to use and it won't connect. I've tried to enable the NIC card which is built in and no dice. It's receiving packets but not sending any. Does anyone have any advice?
