13.5 Config Wi-Fi Adaptor (TL-WN321G+)

There are many different kinds of USB WiFi adaptors in 2.6.25.8 and 2.6.30.4 kernel. We select TL-WN321G+ (321 for short) to do detailed explaination (because we also provide its WinCE driver). For TL-WIN322G+ (322 for short), we can't find WinCE driver, so we only mention it's configuration here.
Note: We use USB interface here. This step can only be finished in next tutorial, but since it's a network device, we are going to put it here.

Enter into config menu, the configuration menu is as following:

The above red part is the driver config for 321, and config it as module; Blue part is the driver config for 322, and we also config it as module.
