WiFi not working after changing 3 wifi card- I/o flex changed still
I need your help,
I currently fix Cell Phones and other laptops and MacBooks too. I don't have much idea about reading schematics. I do have a multimeter, analog and digital
Problem is no WiFi only shows Bluetooth as being descoverable but won't connect
Tried changing the the WiFi card replaced with 3 different cards, erased the full system and reinstalled the OS. Cleaned the I/O board and the flex. Tightened the flex with little extra paper, still same problem but after removing card no Bluetooth option to turn on, no option in network for WiFi tried SMC & PRAM reset nothing helped,
Please help me find the problem, my deep respect for all my experts thank you!
