I am pretty new to OpenWRT, but I followed the tutorials and am pretty sure I did everything right, but when I have cake, p-o-c sqm running, i basically lose all of my speed (81 to 4, 6 to 2). What am I doing wrong? I am using a TP-Link Archer C7 v2 with lede 17.01. thank you!!!
Double check for correct interface.
Queue discipline settings
Link layer settings match for wan connection type.
CPU load while testing. ie has the router got enough cpu power for the link speed.
Have you enabled any flow offloading?
