Frequently asked questions

What matters most for wi-fi interference: causes, tests & fixes?

Nearby networks, Bluetooth, obstacles and household equipment can reduce Wi-Fi consistency without changing ISP speed.

How should I test this?

Test at a fixed location. Record band and device capability. Compare Ethernet and Wi-Fi. Retest after one controlled change.

Does a faster internet plan fix Wi-Fi?

Not when the bottleneck is signal, interference, device compatibility or the local network.
