Can you see your network on the various lists of available networks? As a security feature, some people disable the router from broadcasting its name. The router is broadcasting; however, the router just isn't "advertising" it's broadcasting.
You can also check if your devices are on the same channel as the router. 2.4 Ghz isn't the actual frequency because the frequency is further broken into the thousandths: 2.412 GHz...2.417 GHz...2.422...etc. These thousandths are called "channels" so ensure your devices are on the same channel (1-11).
Is this the Panoramic? I think the 2.4 and 5 GHz bands need the same SSID.
If you could explain what specifically you do and what specifically happens, we could help. Right now, I'm just stabbing in the dark.
