So the complete physical setup is: Linux laptop WRT1200AC TP-Link TL-SG3424 L2 switch This means there are multiple places buffering can occur, that doesn't have fq_codel. I can't tell what switch chip is being used, it's not on http://techinfodepot.info/wiki/Linksys_WRT1200AC and I don't know where to look to find it. In /etc/config/network there is just br-lan and eth0 and eth1. -- Mikael Abrahamsson email: swmike@swm.pp.se
