FreedomBox works on many single board computers. However, many of these boards do not have built-in Wi-Fi capabilities. Even when Wi-Fi capability is available, non-free proprietary firmware is required to make them work.
A solution to the problem is to plug-in a USB Wi-Fi device into one of the available USB ports. There are many such devices available which do not require non-free firmware to work. The following is a list of such devices that work with FreedomBox devices. Some devices based on these chips have tested to work well with FreedomBox including functions such as access point mode.
The free firmware for these devices is not packaged in Debian yet. You can manually download and install the firmware as follows:
sudo su [enter password] cd /lib/firmware wget https://www.thinkpenguin.com/files/ath9k-htc/version-1.4-beta/htc_9271.fw wget https://www.thinkpenguin.com/files/ath9k_firmware_free-version/htc_7010.fw
