Could you post the result of: cat /etc/config/sqm=20 from the router, please? And the output of /etc/init.d/sqm stop ; /etc/init.d/sqm start this might give me a clue where to look... > qdisc ingress ffff: dev eth0 parent ffff:fff1 ---------------- > qdisc mq 0: dev eth1 root > qdisc fq_codel 0: dev eth1 parent :1 limit 1024p flows 1024 quantum = 300 target 5.0ms interval 100.0ms ecn > qdisc fq_codel 0: dev eth1 parent :2 limit 1024p flows 1024 quantum = 300 target 5.0ms interval 100.0ms ecn > qdisc fq_codel 0: dev eth1 parent :3 limit 1024p flows 1024 quantum = 300 target 5.0ms interval 100.0ms ecn > qdisc fq_codel 0: dev eth1 parent :4 limit 1024p flows 1024 quantum = 300 target 5.0ms interval 100.0ms ecn > qdisc fq_codel 0: dev eth1 parent :5 limit 1024p flows 1024 quantum = 300 target 5.0ms interval 100.0ms ecn > qdisc fq_codel 0: dev eth1 parent :6 limit 1024p flows 1024 quantum = 300 target 5.0ms interval 100.0ms ecn > qdisc fq_codel 0: dev eth1 parent :7 limit 1024p flows 1024 quantum = 300 target 5.0ms interval 100.0ms ecn > qdisc fq_codel 0: dev eth1 parent :8 limit 1024p flows 1024 quantum = 300 target 5.0ms interval 100.0ms ecn > qdisc fq_codel 0: dev ifb4eth0 root refcnt 2 limit 1024p flows 1024 = quantum 300 target 5.0ms interval 100.0ms ecn The ingress setup did not go through, which most likely means tc = got unhappy about one of the options. Thanks for your time in testing this, I fear sqm-scripts is not really = in a good shape for cake testing yet.
