===...that did make a difference===
* Connecting the phone, running Stadia, via '''wired Ethernet''' (high latency goes away because the problematic QoS marking has gone, DSCP field = 0)
* Setting a special feature on AAISP and the FireBrick - ''''IP over LCP'''' - this sends the IP traffic as control frames. (high latency goes away). This IPoLCP is a niche feature and has been used in the past to help diagnose problems in back-haul networks: eg: https://www.revk.uk/2015/02/congestion-case-study.html
* '''Changing the DSCP value''' - only packets marked CS6 (192 to 195) are affected. Using values higher or lower and the latency goes away
