Step-by-step guides to diagnose slow Wi-Fi, fix disconnects, find better channels, and test for bufferbloat on your Mac.
Diagnose why your Mac Wi-Fi is slow
Figure out why Wi-Fi is slow on your MacBook or desktop Mac without guessing between signal, router, DNS, and ISP issues.
See whether your Mac latency blows up during download or upload load instead of judging the connection by raw speed alone.
Fix drops, disconnects, and no-internet problems
Pin down repeated Wi-Fi disconnects on a MacBook or desktop Mac without guessing between router, channel, signal, and network-state issues.
Figure out why your Mac shows Wi-Fi connected but cannot reach the internet without guessing between DNS, DHCP, and router issues.
Optimize your channel and reduce interference
Scan nearby networks from your Mac, compare channel crowding, and pick a cleaner 2.4 GHz or 5 GHz channel for your router.
Figure out if interference from neighbors, Bluetooth, or household devices is causing your Mac Wi-Fi problems.
Diagnose why your MacBook or desktop Mac cannot see or connect to 5GHz Wi-Fi when 2.4GHz works fine.
WiFyi shows you exactly why your Mac Wi-Fi is slow — signal, router, DNS, or ISP — so you can fix the right thing.
