Frequently asked questions

What matters most for 2.4 ghz wi-fi: range, iot compatibility & interference?

2.4 GHz usually reaches farther and supports many IoT devices, but has less spectrum and more interference than higher bands.

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.
