WiFi indicator

[jvosudan]

So I have resurrected a 2009 MacBookPro, running Mojave, v10.14.16: When it boots, the wi fi indicator on the Apple bar is greyed out and the dialog box say "WIFI NO HARDWARE INSTALLED". News to me because it was there last time I used it. I reinstalled the OS and still no luck. I must have turned something off and can't find a fix.

Any suggestions?

Hello and welcome.

Normally, that issue is due to either the Wi-Fi card not being connected properly, or a hardware failure. Depending on the exact model, the Wi-Fi card is located inside the black display hinge cover. It's not a user-accessible part, and components can easily be damaged when servicing the display with the hinge cover removed. The Wi-Fi card is particularly sensitive to static electricity, and can easily be shorted out if the cables aren't connected in the proper way.

-You mentioned you resurrected the MBP...what steps did you perform?
-Which exact model is the MBP?

I tried everything in the help "how to fix wi-fi" and the wi-fi indicator is still greyed out. I may have a hardware issue.

Thanks for your reply.

I replaced the hard drive with a SSD and upgraded the memory.

I suspect you are correct and the wi-fi card may be the issue.

Next trip to the Apple Store, I'll have the genius look at it and make suggestions.

Thank you for your reply.
