Slow Wi-Fi
Slow Wi-Fi needs evidence, not a router replacement guess.
A slow Wi-Fi complaint can come from weak signal, low link rate, crowded channels, roaming behavior, DNS delay, gateway latency, packet loss or the internet provider path.
Common causes
- Low negotiated link rate: the device may show connected but transfer slowly.
- Channel congestion: nearby access points can compete for airtime.
- Bad placement: weak signal or high interference can reduce usable throughput.
- DNS delay: pages appear slow because names resolve slowly, not because Wi-Fi is weak.
- Gateway or WAN issues: the local router or internet path may be the bottleneck.
How Infracheck helps
InfraZoom by Infracheck checks Wi-Fi, gateway, DNS and HTTP from the phone. The Windows app checks similar symptoms from a PC. The local appliance adds continuous WAN, DNS, HTTP/TLS, packet loss and LAN history from inside the site.
