I didn't mind that this computer doesn't have a WiFi card because I am right next to my router and can hardwire in.  But after 3 days of running dual monitors and working from home, the ehternet port on the computer randomly stopped working.  Tried different ethernet cords to no avail.  I bought a $12 usb WiFi dongle and have been using the computer to work for 10 hours a day with  no further problems for a few weeks now.
