Thanks for this very precise guide ! Even if my bluetooth was still working fine, my wifi stopped seing any network, and afterwarming a bit more, just activating the wifi crashed the MacBook (Mojave).Afet, it even failed booting 50% of the time (no startup shame). BootCamp failed seing any wifi too (Win 10). So I ordered a used replacement card on aliexpress for 15$. It was worth it!

My old original Airport card was an CE European model 607-4145-A, and the replacement one is a 607-4144-A. I guess the new card is a world model since there is no CE marking on it and because I saw more chanel on first check under System repport/WiFi before activating airport - now it dropped to the same amount of channels, I guess after localizing my Mac. The new card is much faster than the old card too, my 5Ghz wifi is now connected around 230Mbits (speed test at 200Mbits) and the old card before dying was only working at 150Mbits (speed test at 120Mbits) - maybe it was already damaged since a while.

When reassembling, the jack connector cable broke :'( iPod woking fine, with a new battery.... but no more sound. Grrrr
