WiFi doesn't work, even after resets, config deletion, board replace.
Hi! My mid 2014 Macbook wiFi isn’t working, it used to work fine for some time, but then suddenly stopped working. It shows “Error no hardware installed”
I have tried every possible reset (NVRAM, PRAM, SMC), macOS reinstall, network config reset. I even ordered replacement part for Airport board and changed and nothing helped.
Hardware test results in error CNW001
Once in few months it randomly starts to work fine for 1 hour, usually if I haven’t touched my Macbook for a long time, then wifi disappears after an hour and never comes back.
Now after reinstalling Macbook, it doesn’t even recognise wifi hardware, and it doesn’t even show the wifi logo at top, nothing.
Some questions to get things more clear:
- Is there any other hardware part that can be replaced, because i’ve tried the airport board and no success?
- Also does faulty airport board should disable bluetooth? Because Bluetooth is always working fine for me.
- Does faulty wifi antenna can completely disable wifi?
- Is the cable near airport board (IO cable) related to wifi on 2014 mbp? (I know on mbp 2012 it was an issue related to wifi)
Bu iyi bir soru mu?
