I've just bought an RT-68U and set it all up, all wireless clients were able to connect just fine but suddenly last night the 2.4 Ghz WiFi stopped working - none of my wireless devices can see the 2.4Ghz network and entering in the network details manually results in a "network not found" status message.
I've tried powering off/on the router and changing the SSID of the 2.4Ghz network but all to no avail. The 5Ghz network can be seen and connected to with no issue by my dual-band device, but unfortunately not all my wireless devices are dual-band.
Has anyone else has this issue with Asus wireless routers?
