When AREDN spun off from Broadband Hamnet around 2013 they inherited OLSR, the Optimized Link State Routing Protocol. Version 1 was developed in 2003. It was pretty quickly deprecated due to known deficiencies, but AREDN was stuck with it. Several years ago in an effort to help users optimize their links, LQM, the Link Quality Manager, was developed. It allowed nodes to ignore really weak stations, to set minimums on SNR and maximums on link distance. All these would help to maximize the use of precious bandwidth by trying to minimize retries.
With the advent of the Babel routing protocol, developed in 2021 and adapted by AREDN recently, there's no need for LQM - the Link Quality Manager has become the Link Quality Monitor. You'll see those changes in nightly build 20250306.
Additionally, the Wireless Watchdog LQM will be removed; it's no longer needed.
