aj6828: Try changing the mtu to 1500
I tried, it won't let me. I think I'll have to change to the Merlin firmware for that, not a big deal, but I'll have to try it one evening (I WFH 100% and can't break the internet, even if it's slow, during normal hours).
I did turn off QoS which as removed almost all load from the CPU, it's less than 5% when running a speed test. I actually tried it a few times to be sure as I was quite surprised how much of a difference that made to CPU usage.
