我是Android开发的新手,正在尝试使用Android SDK连接到WiFi网络.断开连接的代码工作正常,但重新连接失败.这是我的代码

try {

WifiConfiguration conf = new WifiConfiguration();

conf.SSID = "\"" + networkSSID + "\""; // Please note the quotes. String should contain SSID in quotes

conf.wepKeys[0] = password; //WEP password is in hex, we do not need to surround it with quotes.

conf.wepTxKeyIndex = 0;

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

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

WifiManager wifiManager = (WifiManager)ba.applicationContext.getSystemService(Context.WIFI_SERVICE);

wifiManager.addNetwork(conf);

List list = wifiManager.getConfiguredNetworks();

for( WifiConfiguration i : list ) {

if(i.SSID != null && i.SSID.equals("\"" + networkSSID + "\"")) {

wifiManager.disconnect();

wifiManager.enableNetwork(i.networkId, true);

wifiManager.reconnect();

break;

}

}

//WiFi Connection success, return true

return true;

} catch (Exception ex) {

throw ex;

}

我将此代码包装在一个用在其他应用程序中的jar文件中.当我调用此方法并尝试使用SSID和密码连接到WEP网络时,我不断收到以下错误消息：

android.system.ErrNoException: recvfrom failed: ETIMEDOUT (Connection timed out).

该错误确实表明某处存在连接超时,但是我无法弄清楚该错误来修复我的代码.我可以在代码中引入任何指针和更改以使其工作？
