I'm trying to flash OpenWRT firmware (https://openwrt.org/toh/linksys/linksys_wrt3200acm) 18.06.4 to Linksys WRT 3200 ACM router. After flashing, the internet LED keeps fast blinking, but WIFI LED never light up.
SSH into the router and able to reboot to stock firmware, which works.
Also if I flash the oem factory firmware, it works.
My internet provider is RCN.
Wireless is disabled on a fresh flash or configuration reset. It needs to be enabled either through the command line or LuCI (if installed) over a wired connection from a LAN port.
Thanks for the reminder. Yes, I installed snapshot which works great! It even fixed one of the other problems that the stable version somehow didn't give me the full speed. I have 300Mbps download, but with stable version, I only can go ~20Mbps download.
