"No AirPort card installed °_° (wifi crash)"에 답변Phew, yes. My problem started when I installed a 1TB hard drive instead of the DVD drive. I bought a kit from MCE Tech, installed it and reinstalled everything onto the new disk. No problems so far, except. "Wi-Fi hardware could not be found" I did all the things proposed including erasing the HD and reinstalling Lion and everything else. No change. So now I've bought a new WiFi-card for my MBP 13' mid 2010 from Hong Kong and tools from IFixIt. Tonight I sat down (in Stockholm, Sweden) to assemble the kit. I got as long as "Removing the 6,5mm torx screws" when I realized that this screwdriver was not mentioned in the IFixIt manual'... Ok, so I had to close the MBP again, order a new screwdriver and now I'm waiting for it to arrive. I'll get back to you with my progress.
