Great collaboration on these two fantastic routers on the openwrt forum:
https://forum.openwrt.org/viewtopic.php?id=32320
Above all kudos to aryufan. Well done and thank you everyone else who
contributed.
To-Do: LED for wlan is not yet activated
To-Do: TxPower over 20dBm (RB751U) or 22dBm (RB751G) are not accepted by
the router
