i opened up my Mac and cleaned it after water because it was running slow and the fan was going crazy. IT worked and I hadn’t no notebook issues when I ran apple diagnostics but now I can’t see all my wifi networks or even connect to my phone wireless hotspot And it keeps saying password invalid wen it’s always right!
The wifi shows the same networks like 3 of them but there use to be at least 30 as I live in an apartment block. Is this a airport problem or antenna??
