12 2. 단독형 AP 설정 Web 접근 cisco Cisco

13 2. 단독형 AP 설정 SSID 생성 사용할 SSID 입력 Security 탭의 SSID Manager 로접근 사용할 Radio 선택

14 2. 단독형 AP 설정 Beacon 선택 클릭 생성한 SSID 를선택 생성한 SSID 를선택 SSID 생성시 Radio 를하나만선택하면선택한 Radio 만 Beacon 선택가능 Beacon 을선택하지않으면 Client 에서생성한 SSID 가보이지않음

15 2. 단독형 AP 설정 암호화방식선택 Encryption manager 로접근 Cipher 선택후 AES CCMP + TKIP

16 2. 단독형 AP 설정 WPA 설정 ( 생성한 SSID 의암호설정 ) SSID manager 로접근 Mandatory WPAv2 사용할 Password 설정 (8 자리이상 ) Password 가 8 자리이상사용해야 n 사용가능

17 2. 단독형 AP 설정 Radio Enable Enable Network Interfaces 로접근 다른 Radio 도동일한방법으로 Enable SSID 가하나라도생성되지않으면 Enable 되지않음

18 2. 단독형 AP 설정 여기까지셋팅하셨으면기본적인무선랜셋팅은완료 지금핸드폰이나노트북에서 Test 라는 SSID 가확인되시죠 ~?

19 2. 단독형 AP 설정 채널확인 inssider 라는프로그램을통해주변무선환경을측정 중첩되지않는채널로변경

20 2. 단독형 AP 설정 채널변경 중첩되지않는 6 번채널로변경 클라이언트가접속되어있는상태에서채널을변경하면모든클라이언트가접속이끊어진다. 초기무선랜설계시 AP 위치를파악하고중첩되지않는채널을잘설계해야한다. 채널중첩시무선랜속도저하및클라이언트접속이되지않는현상이발생한다.
