Hi All,<div><br></div><div>In lieu of recent progress getting HT speeds to work on some Nanostation M5s that I am deploying with OpenWRT/OLSR, I am curious how I can adapt OLSR link quality monitoring for the newer radios.</div>
<div><br></div><div>Right now, the three 5GHz OLSR nodes I've deployed all report 1.00 for LQ and NLQ, I believe because their packet loss at 150Mbit/s+ connection speeds drops to a negligible amount. With one active gateway, this results in a simple star topology.</div>
<div><br></div><div>Ideally, I would like OLSR to build multi-hop routes between nodes with high connection speeds, e.g. 150Mbit/s vs 60Mbit/s. However, the only way I get get such link info is using the iw command line tool, e.g. </div>
