Choosing a USB WiFi Dongle WiFi networking can be added to any ComfilePi panel PC with a USB WiFi dongle. However, finding a reliable WiFi dongle that has drivers included in the Linux kernel can be challenging. Our research has led us to believe USB WiFi dongles with a MediaTek chipset are probably the best choice. MediaTek submits their drivers upstream to the Linux Kernel, so they pass the Linux kernel review process, and are ready to use out of the box.

Enable the Internal Watchdog Timer The ComfilePi's SoC has an internal watchdog timer that can be used to automatically reboot the system should it ever become unresponsive. It is also recommended to enable the read-only file system overly to protect the file system from corruption should such an event occur.

Optimizing to Reduce RAM and Storage Utilization Reducing RAM Consumption The latest Bullseye OS will typically consume about 300MB of RAM, at idle, after booting to the desktop. If running high memory consumption application like the Chromium browser, that could quickly rise to 600MB or more, depending on the solution.

Set the Date and Time Run the following commands in a terminal to set the ComfilePi's date and time and save it to the ComfilePi's RTC. # Disable synchronization with the time server sudo timedatectl set-ntp false # Set the date and time (e.g. January 2nd, 2026 5:30am). This will set both the system time and the RTC's time. sudo timedatectl set-time '2026-1-2 5:30:00'
