Flashed SL-R7205 with the latest 17.01.4 without keeping existing config and noticed that default Ethernet port configuration is incorrect, so all Ethernet ports are non-operational. Earlier, there was a way to change port configuration via WiFi but in latest builds WiFi is turned off by default so the only way to access the router is a serial console.

Please change default Ethernet port config as described in [[https://wiki.openwrt.org/toh/widemac/sl-r7205|model notes]].
