5GHz USB Wifi for older Raspberry Pi's
I recently made a k3s cluster of Raspberry Pi 3's, which only have 2.4GHz wifi. Unfortunately, the network where I work is 5GHz only.
Jump on amazon.com and search for "Edimax AC600". This appears to be the smallest wifi dongle which supports raspi's.

(here's the gist:)
sudo apt-get install raspberrypi-kernel-headers build-essential git clone https://github.com/gnab/rtl8812au.git cd rtl8812au # edit the Makefile: # CONFIG_PLATFORM_I386_PC = n # CONFIG_PLATFORM_ARM_RPI = y sudo bash install.sh reboot
