I recently replaced the wifi card and cable and it did not fix the problem. What did fix it was to press down very hard on the connectors. Even with this fix, after carrying the laptop around wifi was lost again with the "no hardware installed" notification. I opened the case again and tightened all screws on the logic board and optical drive. I found a few screws were not fully tightened. I conclude that after 5 years the wifi cable pop off the connector just enough that the logic board can not communicate with the wifi card. After this fix, so far so good, but I would not be surprised if I'm opening the case often to reset the wifi cable.
