Wi-fi not installed

I'm having this issue with a MacBook Core 2 Duo: Wi-fi appears as not installed after waking up from sleep; I've reseted SMC and NVRAM, Reinstalled the OS and replaced the Wi-fi card and it is still the same.
I also tried disconnecting the bluetooth adapter since I've read that it messes with the wi-fi adapter on later models, but nothing seems to work.

Any Idea?

Thanks in advance

What does "not installed" mean?

Is it just not connecting to any network?

Are you completely lacking any and all wi-fi preferences?

Have you booted into safe mode to test (hold shift while booting)?

Booted from the recovery drive to test (command-r while booting)?

Have you checked the network to ensure it's compatible (80211 /a/b/g/n - WPA2 or WEPA)?

Bluetooth is a different matter entirely. Yes wi-fi activity can cause interference in some cases with Bluetooth. But I've never heard of Bluetooth causing issues with a wi-fi signal.

Thanks for your response, in the image you can se what I mean.

Wi-fi works well after reseting the NVRAM (Command (⌘), Option, P and R at boot) several times, then you put it to sleep an hour or so and wi-fi is gone again.

Hope I made my self clear, thanks in advance

.... "after you boot up normally wifi disappears again"

So if you are in safe mode or booted to the recovery drive, the WI-fi still malfunctions? Or does wi-fi work correctly when booted in safe mode and only when you reboot normally does it stop working again??

Sorry, you aren't being very clear with your replies.

If things work as expected in safe mode or from the recovery HD, they you have an OS issue and you may need to reinstall the OS.

I apologize, Sir.
wi-fi works correctly when booted in safe mode and when you reboot normally it stops working again. And I have already reinstalled the OS twice.

Thanks in advance

You may need to do a complete erase and install of the OS and NOT use Migration Assistant. You may be just migrating the problem back.

If everything is functional in Safe Mode, that's a clear indicator that there is nothing wrong with the hardware or the OS. The issue is entirely due to some other software installed.

I made a fresh install from an OS X DVD, never used Migration Assistant. HDD was formated and everything.

Thanks

The fact that things work when booted into Safe Mode ONLY means there's other non-Apple software causing the issue when booted normally. There's literally no other interpretation of that.

If there was a hardware or OS issue, then Safe Mode would also show the issue.
