I own a Netgear R6300v2 and have had Tomato on it. However, I prefer OpenWrt to Tomato and DD-WRT and have been waiting for OpenWrt.
I have just noticed that there is a build for Netgear R6300v2 in /releases/18.06.1/ folder. In the LEDE archived forum, I found that 2.4G wireless was partially supported and that 5G was not at all. I am wondering what the status is and how stable the 18.06.1 firmware is on this device ?
