The OpenWRT One Wifi Router, hardware designed by the
OpenWRT project, for Open Source. Fully Open Source, FCC-Certified WiFi. The box is a lot nicer than those plastic ones. Besides the regular FLASH, there is a write-protected one that rewrites the main FLASH when you throw a switch, so you can't brick it. Order it here, takes about 12 days to ship. https://www.aliexpress.us/item/3256807609464530.html
