I recently got my Raspberry Pi to act as a WiFi Router with shaping by using hostapd, tc, and iptables together to broadcast as an Access Point, apply shaping rules, and apply packet marking respectively.
This can be done on any device with 2 NICs but this may come in useful for anyone using the Pi as a router but doesn’t want people using all the bandwidth.
I will be going through the iptables and tc configuration in this post, but I won’t go through the hostapd setup as that was the same as part 3 of my Raspi WiFi Access point guide.
I started off with a blank slate of Raspbian Server Edition again, and I didn’t need to install any utilities as iptables and tc are installed by default.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
