Tip to solve streaming & rebuffering problem

Hi - After moving to a new house, I started to have a lot of issue with all my Squeezebox devices (12 in total) where one duet was not capable of streaming more than a few mins w/o loosing connection, sync was a nightmare and all sort of other issues ==> my devices were unusable. WIFI coverage is made by 2 AP and is good (not great but good). The most problematic duet was having the lowest coverage (30-40%) and things were improving massively with that same duet closer to the AP. After a lot of investigation, including spectrum check of my WIFI environment, WIFI load analysis etc ... I think I got the problem solved as streaming is 100% reliabe for more than 3 days. Problem was found by using WireShark and was linked to Win7 SP1 (x64) AutoTuning behavior : seems that quickly, Win7 TCP/IP stack was trying to extend the RWIN to a point where segments where guaranteed to be lost by the duet under low coverage and then repeat started to kill the whole streaming process. So, see http://www.speedguide.net/articles/w...08-tweaks-2574 and disable Windows Scaling heuristics & TCP Auto-Tuning to lock RWIN at 64K works - I need to figure the impact of my network speed though.

Hope it helps somebody
