Need your lspci information, or lsusb if your wifi is connected via USB, to get what kind of wifi adapter you have

So you never got your wifi working before? Just curious if it was something broke versus a new setup...

This is your wifi adapter. Apparently this is fairly new and from a cursory search, this is first supported built-in, in Linux-3.8.

Apparently rtlwifi works with this device, but it might need the rtl819x module...

I think the other default settings for wifi works or it will pull in the right ones automatically, you should try it and see what it does, there's a whole bunch of dependencies (80211 stuff) that tend to be pulled in correctly.

You probably need to also emerge the linux-firmware package as well.

driver loads ok but no wlan0
both fails to make wlan0 device
how can i trouble shoot this problem?

most of the wifi drivers I've seen at least would detect the HW without config, whether or not it works is another problem.

So when the module is modprobed, what does it report in dmesg? Is it completely "hardware not found" (wrong driver?)

Looks like you're most of the way there.

Now you need to know how you configured your access point (WEP, WPA, etc.)

At this point the path diverges depending on how you want to configure it... I took the easy way out as my wireless clients are laptops and they have GNOME installed, so networkmanager and its GUI nm-applet made it very easy to configure. I've heard wicd works well too for non-GNOME/KDE installs.

If you don't have encryption turned on (not recommended!) all you would need to do is

iwconfig wlan0 essid <your ssid>

and things should start working (IIRC.) You should be able to run DHCP at this point.

WEP is not too much more (also not recommended)

iwconfig wlan0 key 0 <your-wep-key>

Likely you're using WPA/WPA2 and you need to use wpa-supplicant which I haven't used directly before -- networkmanager dealt with it automatically...

glad to see your on the right track.... id advise against using wicd as your primary connection method. it works, though networkmanager's had more consistent solid performance for me.

merge nm-applet to manipulate network manager through the gui. (networkmanager might pull it in) id follow the wiki to install it....

Yes, if you're using Gnome you should be using networkmanager. The nice thing about it is that it's very well integrated with dbus so networkmanager can signal network features as it goes up and down - it's very slick. Props to Redhat for writing this.
