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.

Sep 07, 2015 I'd suggest going into device manager and editing the device's advanced settings - limiting the bandwidth to 20mhz, instead of 20-40mhz. I always have trouble with that. As an aside, i downloaded an amd 300mb driver using the microsoft driver, and downloaded it. You can make the most of your PC Speakers and Microphone using Realtek HD Audio Manager. Learn about how to open & use it & the features included in it.

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.

Not all N cards support 5GHz. This one doesn't.
A clue is the fact that it is labelled with B and G but not A. Of the standards older than N, B and G both used the 2.4GHz band while A used the 5GHz band. N cards supporting both bands are often labeled as supporting A/B/G/N, whereas N cards supporting only 2.4GHz are often labeled as B/G/N.
The newer standard AC also uses the 5GHz band. Only N supports both bands, with mandatory 2.4GHz support and optional 5GHz support. So if a device supports AC and N that should mean it supports N on both bands.

Sep 27, 2015Messed around with the drivers, now the ethernet device doesn't show up in the network adapter settings, although it shows up in the Device Manager. It is also apparently in sleep mode.So after formatting and installing Windows 10 x64 on my Dell Inspiron 3542, I decided to update/re-install the drivers from the official Dell download page. Windows Update had taken care of the hardware but the versions were outdated, so I set to work. After successfully installing almost all the drivers, I ran the Ethernet Controller Driver and after installing it, the ethernet device was disabled. BTW, the device shows up as 'Realtek PCIe FE Family Controller'.
I enabled it but it still remained disabled. In the Properties dialog box it gave me the option to disable it, which means that it thinks that the device is enabled, which it is not. It is visible in the Device Manager, so it is being recognized. After restarting to come to the same result, I deleted the driver from Device Manager and re-installed it, which didn't work. (I don't remember if I attempted a roll-back, although if I did then it obviously didn't work either.)
Then I went to the Realtek official website and downloaded the Win10 Auto-installation Program. It asked me to remove the previous installation from Dell, and near the end, it gave me the error, 'The Realtek Network Controller was not found. If Deep Sleep Mode is enabled, Please Plug the Cable'. And after this, or after deleting and re-installing the Dell driver (I unfortunately don't remember when), the ethernet device disappeared from the adapter settings. Now there's only Wi-fi there.I really want my ethernet back, even though I have wi-fi to connect to the internet. The only solutions I can see are to either get the Dell driver working or to remove the device from sleep mode.
