Mac Wi-Fi slow or dropping after sleep: why and how to fix it
Why a Mac's Wi-Fi is slow or drops after waking, how to reset the connection quickly, and the settings that make it worse.
Why is my Mac Wi-Fi slow after sleep?
On wake the Mac reconnects and may land on a weaker access point or band, or keep a stale connection. Some routers handle the reconnection poorly.
What is the quickest fix?
Turn Wi-Fi off and on from Control Center. If it is a pattern, forget the network in System Settings, Wi-Fi and join it again.
What else helps?
Try turning Private Wi-Fi Address to Fixed or Off for your home network in its Details, and keep the router's firmware up to date. Why Mac Wi-Fi is slow covers the other checks.
