[Cake] bringing up a new router/connection

[David Lang]

I finally got a decent speed connection (cablemodem 600/35) to supplement my dsl 
(8/1) and am trying to test it's current performance before I install/configure 
cake and am running into some grief. 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
