I am hoping to get some pointers to find the bottleneck. the ISP devices have bad bufferbloat, ping times go from ~20ms to 8.8.8.8 to t least 120ms, and I saw one time when they went to 1200ms I'm using a c2600 router running the current openwrt https://openwrt.org/toh/tp-link/tp-link_archer_c2600_v1 and have mwan3 configured to provide failover between my wan connections. I have a block of static addresses for the router with the ISP router in bridge mode when plugged directly into the ISP router, I am getting the advertised speeds, when going through the c2600 I top out at 200-300Mb download and 10-15mb upload eth0.2 is the high speed cablemodem # tc qdisc qdisc noqueue 0: dev lo root refcnt 2 qdisc mq 0: dev eth0 root qdisc fq_codel 0: dev eth0 parent :1 limit 10240p flows 1024 quantum 1514 target 5.0ms interval 100.0ms memory_limit 4Mb ecn qdisc mq 0: dev eth1 root qdisc fq_codel 0: dev eth1 parent :1 limit 10240p flows 1024 quantum 1514 target 5.0ms interval 100.0ms memory_limit 4Mb ecn qdisc noqueue 0: dev br-lan root refcnt 2 qdisc noqueue 0: dev eth1.1 root refcnt 2 qdisc noqueue 0: dev eth0.4 root refcnt 2 qdisc noqueue 0: dev wlan0 root refcnt 2 qdisc noqueue 0: dev eth0.2 root refcnt 2 David Lang
