WiFi shows weak security with WP, but my network is WPA2
My MacBook Air says the WiFi has weak security with WPA, but the router is set to WPA2 and my other MacBook Pro doesn't show the same error. This MacBook Air also has slow WiFi compared to the other MacBook and my iPhone. Is there a way to delete and reinstall the wifi service or otherwise refresh the wifi setup on the MacBook Air?
