DIY Wifi Pineapple MK4 and MK3
Our Alfa AP121U routers already have the stock, factory firmware pre-installed on them. All you would need to get is one of our 5 console cables/adapters to access the terminal of the router to flash new firmware, SCP or create a TFTP server to put your new firmware on the AP121U to be flashed and run the command:
sysupgrade -n /tmp/upgrade.bin
