Was playing Everquest on my Sony Vaio when I went linkdead. I currently use the laptop with a wireless connection which is located out in the garage. Did some limited troubleshooting and found that "a network cable is unplugged". I checked the network connection and it does not see any local wireless networks in the area. My pc is having no such problems. I cant find any diagrams as to where my wireless adapter is on the computer to see if it shook loose. Any ideas??

Tell us more about what connection you have by brand and age. Any failure of the cable modem or telephone modem can produce the error message, A Network Cable is unplugged.
Best first step, is to unplug your cable modem or Ethernet connection, then insert a straigtened paperclip wire into the small hole on the back of the router/modem to reset it.
Then plug the connection back in with everything turned on, and reboot your system.
