Queries Installing OpenWrt on Netgear (Model R6020) AC750 WiFi Router

Installing and Using OpenWrt
1

Hello.

Hope you are all doing well.

I want to install OpenWrt on my Netgear Model R6020 AC750 WiFi Router (Router Documentation).

I believe the model is supported as I found it on OpenWrt's website : https://openwrt.org/toh/netgear/r6020

I am currently using Linux Mint XFCE.

Can someone please suggest me the following -

  1. Please let me know if the router is supported.
  2. How I can install the firmware on my router.
  3. Are there chances of things breaking due to / during install?
  4. If things do break, how can I solve it and get connection back?

Thank you for your time.
