AMD: 

sudo apt install amd64-microcode


Download manually in https://sourceforge.net/projects/xanmod/files/microcodes/

See installation guide Here.

Setting the CAKE Network Queue Management


To use the CAKE Queue Discipline in systems with systemd (>=217), will need to replace the default fq_codel. 

echo 'net.core.default_qdisc = cake' | sudo tee /etc/sysctl.d/90-override.conf

Save and reboot.

Check it: 

tc qdisc show


For Routers w/ OpenWrt 18.06+ Firmware


Enter via ssh command line (default ip 192.168.1.1): 

ssh [email protected]

Update and install the sch_cake: 

opkg update && opkg install kmod-sched-cake

Set cake qdisc in sysctl: 

printf '%s\nnet.core.default_qdisc=cake\n' >> /etc/sysctl.d/10-default.conf
reboot

Check it: 

cat /proc/sys/net/core/default_qdisc
