I have a Realtek RTL8188CE 802.11b/g/n on my Quantal amd64 system. I installed the kernel modules for that card and modprobe that module. I can only view to the 2.4GHz WLANs. The module Im talking about was downloaded from the realtek page.

Here is some good info. Well my configuration.

The Realtek RTL8188CE WLAN adapter is designed to connect to a IEEE 802.11b/g/n communication protocol. This protocol is available for both the 2.4, and the 5.0 GHz frequency band. However according to the hardware specifications this adapter like many other "802.11n" adapters only supports the 2.4 GHz band:

To be able to connect to signals in the 5.0 GHz band you need to have an adapter supporting this. These usually are named as "dual-band" or similar.
