Wi-Fi is not working but bluetooth works
I upgraded the keyboard of my MacBook recently, this tutorial helped me at the point to do the stuff: Upgrading your 2.0Ghz 13" Aluminum Unibody Macbook to a Backlit keyboard
After installing the new keyboard, the keyboard works well, but the Wi-Fi says "No hardware installed", i tryed to reset the SMC and NVRAM, the result is the same "No hardware installed". But the Bluetooth works well, the system monitors says that is there no Wi-Fi Card or something else, but the Bluetooth get listed.
My next try to fix the problem was to install the MacOs on a new drive to check for software failure, this changed nothing.
Did I damage one specific cable? Which one? Or it is something else?
Thank you in advance
