When I first install Hassio on a rpi3, HA was able to detect my ddwrt router. A few weeks after, my sd card crapped out and I had to reinstall from scratch with a new card (usb stick). HA does not detect my router any longer. I have tried manually inputting upnp: in the config file. My router upnp is still set to enable.
Really stump as how to troubleshoot this. My router has not been upgraded or any setting changed.
