Ah right, I see. My Turris Omnia does something similar, but also has a
separate hardwired WAN port. I just assumed the WRT1200AC was similar
(it's been a while since I used mine, since I replaced it with the Omnia).

Another thing you could try, to confirm that the culprit is the shaper,
is to use HTB as a shaper and run CAKE in unlimited mode as the leaf
qdisc. This *should* work, and if it doesn't give you the latency
spikes, then its definitely a wink in the direction of the shaper...
