Wifi/ko

이 게시글은 WiFi 네트워크 장치 설정 방법을 다룹니다.

WiFi 설치 과정
젠투를 설치할 때 WiFI 연결이 필요할 경우 젠투 소형 설치 CD에 제한된 종류의 드라이버와 WPA/WPA2/기업용 연결 설정 도구 wpa_cli(wpa_gui 아님) 가 있음을 참고하십시오.

소형 설치 CD에 필요한 드라이버 또는 wpa_supplicant 의 그래픽 프론트엔드가 없다면, 시스템 복구 CD와 같은 기타 라이브 CD를 마련하십시오. 젠투 라이브 CD가 아닌 경우 특별한 과정이 필요합니다.

하드웨어 감지
First detect the Wifi controllers. or are command-line tools that can be used for this task.

If a Linux (LiveCD/USB) is booted that makes a Wifi connection:

The driver will be identified with.

If the booted system does not make a Wifi connection, then obtain a full list of hardware identifiers from the current system. This list can be used to identify the proper driver later:

Copy the list of PCIID's that the command produces and paste it at http://kmuto.jp/debian/hcl/.

For USB devices, a similar approach can be taken. First obtain the list of detected USB devices on the system:

This command produces the PCI ID, manufacturer, make, model, and/or chipset of every USB device attached to the system. Of these, the chipset may be the most useful information. Googling linuxwireless.org  is often the shortest way to find a USB NIC driver and firmware name.

Alternatively, can be used to obtain the necessary information:

This command produces a list of all drivers, regardless of the device being PCI or USB based.

Kernel
드라이버를 확인했으면, 리눅스 커널을 설정할 차례죠.

WEXT
The "cfg80211 wireless extensions compatibility" option aka WEXT will support old wireless-tools & iwconfig.

장치 드라이버
Next the right set of corresponding kernel options need to be enabled, based on the drivers and hardware detected previously. The recommendation is to build drivers as modules. Also be sure to enable AES cipher support in the kernel if the wireless network uses WPA or WPA2 encryption.

LED 지원
To enable LED triggers for different packet receive/transmit events, compile the kernel with the following options:

펌웨어
In addition to the kernel driver, some chipsets also require firmware. If required, locate it on the following list and install it:

If the driver requires firmware but does not appear on the list, it will be necessary to download it manually and place it in.

WPA supplicant
If the wireless network is set up with WPA or WPA2, then needs to be used. For more information on configuring wireless networking in Gentoo Linux, please read the Wireless networking chapter in the Gentoo Handbook.

dmesg
If none of these methods work be sure to check output for errors. It is likely a kernel driver or module has not been loaded properly:
