WIFI 접속방법

WifiManager 의 enableNetwork(networkId, true)

메소드를 쓰면 접속이 됩니다.

이건 WifiConfiguration 의 설정 방법이라고 생각하시면 될것 같습니다.

첫 공통 부분입니다.

WifiConfiguration wfc = new WifiConfiguration();

wfc.SSID = "\"".concat(ssid).concat("\"");

wfc.status = WifiConfiguration.Status.DISABLED;

wfc.priority = 40;

Capabilites 가 Open 일때 설정입니다. (한마디로 키값없이 바로 접속할수 있는거지요)

wfc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);

wfc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);

wfc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);

wfc.allowedAuthAlgorithms.clear();

wfc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);

 

wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);

wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);

wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);

wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);

이제 WEP  방식 입니다.

wfc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);

wfc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);

wfc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);

wfc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);

wfc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED);

wfc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);

 

wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);

wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);

wfc.wepKeys[0] = "\"".concat(password).concat("\"");

wfc.wepTxKeyIndex = 0;

그다음 WPA, WPA2 방식입니다. 동일하네요 ^^

wfc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);

wfc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);

wfc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);

wfc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);

wfc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);

wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);

wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);

wfc.preSharedKey = "\"".concat(password).concat("\"");

위의 방식으로 WifiConfiguration 을 설정해주시고 아래의 방법으로 접속하시면 될겁니다.

WifiManager wfMgr = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);

int networkId = wfMgr.addNetwork(wfc);

if (networkId != -1) {

// success, can call wfMgr.enableNetwork(networkId, true) to connect

}
