If you’re having problems doing a factory reset on a Ubiquiti EdgeRouter, and can’t ping the router on 192.168.1.1 or connect to the admin web interface, you may want to check that you are connecting your computer to the eth0 port on the router. It’s not immediately obvious that this is where the admin interface is residing at https://192.168.1.1. Oh, and don’t forget to hardwire your own computer to the 192.168.1.0-network. This is really a no-brainer, but still not entirely obvious.
