Wifi and Bluetooth won't work anymore "Hardware not available", Macbook Pro Early 2011, High Sierra

Dear community,

I'm working on my Macbook Pro Early 2011 on High Sierra 10.13.6 I know it very old, but it still runs smoothyl, I changed to an SSD hard disk, increased the RAM some time ago, so everything is fine. A further iOS update was not possible anymore however.

Yesterday, out of a sudden Bluetooth did not work anymore, it says "Blootooth not available". The Bluetooth sign has a bar through it. I cannot activate it.

Now today, Wifi is not working anymore, it says "no hardware installed" and the Wifi symbol shows an "X", I cannot activate it.

I really don't know what to do. Do you have any suggestion?

Thank you very much!

Best,

Steffen

MacBook Pro 13″, macOS 10.13

Thanks! So I did the PRAM reset 3 times. After the second time the Wifi button was available again, but Bluetooth was still blocked. After the third time both were unavailable, with the same error message.

So I should try to reset the SMC?

Any other ideas, if this does not work?

Thank you!

Thank you! This would definitely an option, not so practical, though. I checked a bit more, and it seems that WiFi and Bluetooth are linked together in the MacBook Pro and the board can be replaced. Maybe this is an idea?
