If you choose to build it as a module, it will be called rtl8192ce --------------------------------------------------------------------- If you like to check if RTL8192CE is enabled in your kernel's .config file. If it isn't, you probably want to compile it as a module, and then add rtl8192ce to /etc/conf.d/modules as well. Oddly enough, I had a few other CONFIG modules not included, namely CONFIG_80211. But, when I activated it, my kernel got bricked, and on reboot, I got dumped in some prompt that said that the system couldn't find a root and I should press Enter to continue, Q to skip, and something else would give me a shell. I just did a genkernel --menuconfig kernel and built in the modules, the compile went smooth, and I made no other changes. But now, like I've mentioned, I've got a bricked kernel.
