WiFi speed for 2 M1 mini computers on same network 300 mps are very different

Why would WiFi speed from one M1 mini and another M1 mini on same G5 network at 300mps be so different, reduced to 100mps?

Check which Wi-Fi band you’re connected to. Hold down the Option (⌥) key and click the Wi-Fi icon in the menu bar on the slower Mac. Look at the Channel value. If it’s between 1 and 13, you’re connected to the 2.4 GHz band. If it’s 36 or higher, you’re connected to the 5 GHz band.


Also check the RSSI value. If it’s significantly lower (for example, -70 dBm or worse) than on the other Mac, a weaker Wi-Fi signal could explain the slower speeds.
