How To Add An Ethernet?
I have an old desktop PC which is running on XP, I am on broadband currently using an external modem. My ISP has sent me a Router, cables and Micro filter for me to set up a wireless connection. I do not have an Ethernet port on my PC to plug in the RJ-45 cable. Can I add an Ethernet port (like I did USB 2.0) and if so is it quite easy to do?
