After a routine update of OneDrive app, my MacBook Pro 2010 restarted and the WiFi is no longer working. I tried to reset the connection, the location, deleted the network list, reset the P R memory and the SMC.... still nothing. The boot+D shows exclamation mark and a message: apple.com/support-3403D..... The WiFi still shows that it is working, but can't discover any network. What else can I do?
Hi,
Try to check your MacBook Pro WiFi module with Apple Diagnostics if it reports WiFi related error(CNW001, CNW003 to CNW008)
Use Apple Diagnostics to test your Mac - Apple Support
I tried to run the diagnostics (hold D while boot, right?), but it displays some exclamation and a link: apple.com/support-3403D. When I type it (from another session, because in diagnostics mode nothing else is working) it says unknown page. That was the point I ran out of ideas and posted the question here.
WiFi cannot discover any network. MacBook Pro 2010
