I just installed the latest supported version on an old ASUS RT-N12 B1. Everything went smoothly enough but when I log into LUCI there is no Wireless option in the Network menu.
I'm really not sure how to begin troubleshooting this one.
I tried re-uploaded the firmware from within LUCI and also did a Restore from the Backup / Flash Firmware menu but neither of those restored the wireless menu.
There is a 3-way toggle switch on the back of the device labelled "Router | Repeater | AP" but with OpenWRT installed it doesn't seem to have any effect as I have restarted the device with the switch in every position.
I see no flags on the OpenWRT hardware page for this router. and my Linux skills are basically nonexistent so I'm at a loss for the time being.
I welcome your suggestions.
