== The Problem ==
Our customer moved house in early 2021 and we provided a VDSL line, a FireBrick FB2900. The VDSL was supplied over TalkTalk
The Wi-Fi itself works very well. But since the install the customer soon noticed problems with some 'real time' applications such as webRTC, Google Stadia, Nest Camera video streaming. The problem was with latency, which was caused delays with the live streaming of video and audio.
== The cause ==

=== What's DSCP and CS6? ===
DSCP (Differentiated Services Code Point ) is a field in the header of IP packets. usually left empty, but a value can be added which will
CS6 is one of these classification, and CS6 is described as 'Network control' and is one of the highest classifications available.
===...that did make a difference===
* Connecting the phone, running Stadia, via wired
* Setting a special feature on AAISP and the FireBrick - 'IP over LCP' - this sends the IP traffic as control frames. (high latency goes away)
=== Things that were not tried ===
*Migrating the line to BT
== Further tests ==
With A&A having a lively IRC channel, we asked customers to try our ping test to see who far spread the problem was, we found out
* All AAISP TalkTalk VDSL lines tested showed latency
* All AAISP TalkTalk ADSL lines tested showed latency
* A TalkTalk business VDSL line
* A non-AAISP TalkTalk wholesale VDSL
* No AAISP BT lines tested showed latency
* No AAISP Ethernet lines showed latency
