* '''Test Method''': We flashed the Raspberry Pi OS Legacy (6 May 2025) version and used the script [[File:Wifi-signal-monitor.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
* '''2.4GHz or 5GHz frequency band''' :Since the Raspberry Pi Zero 2W only supports the 2.4GHz IEEE 802.11b/g/n WiFi band, you can only access 2.4GHz SSID hotspots.
Based on the above test results, we can draw a conclusion: X306-C1 can meet the needs of devices using Wi-Fi when close to the router, which should be attributed to the larger heat dissipation hole design on the surface of the X306-C1 shell.
