The problem here is that DD-WRT has a setting for transmit power, and on some routers the setting was functional, and could be used to broadcast with power well in excess of FCC limits. Those limits aren’t just there for weather radar, they also make sure you don’t stomp all over your neighbor’s wifi.
I have mainly ASUS routers, all run 3rd party software fine but the firmware limits this particular parameter, and only this one. TP-Link’s decision to lock down their whole routers can’t be blamed on the FCC.
