GL-USB150 Microuter

Installing and setting up AREDN (Amateur Radio Emergency Data Network) firmware on a GL-iNet GL-USB150 Microuter is simple an easy with just a few short steps to get this node on the air in an AREDN Network. Be sure to review the excellent AREDN Doc on getting started – will be using the GL-iNet First Install Process as a reference to get the AREDN firmware loaded on the GL-USB150 Microuter. The main use case will be have any computer with a USB port get instant access to an AREDN mesh network – you only need to be near another mesh node for it to connect.
