Testing the impact of metal casing on ZERO 2W WiFi signal It should be noted that the metal shell will have a certain shielding effect on WiFi, and the farther the device is from the router, the greater the effect will be. We tested the effect of the X306-C1 metal shell casing on Wi-Fi signal, and the ZERO 2W WiFi signal.results are as follows:
{| class="wikitable"
| Test subjects || X306-C1 metal housing
|-
| Test Method || We flashed the Raspberry Pi OS Legacy (6 May 2025) version and used the script wifi_signal_monitor[[File:Wifi-signal-monitor.sh zip]] (download and unzip it) to obtain the WiFi signal strength with and without the X306-C1 metal case.
|-
| Other notes: || The Raspberry Pi Zero 2W motherboard is about 3.5 meters away from the router, with no obstructions in between. Use the script wifi_signal_monitor.sh to test
