Question

我正在创建一个Android应用，可以将您连接到具有特定BSSID的WiFi。我已经实现了扫描所有wifis的部分，并使WiFi配置成为WiFi网络安全类型的功能。我还实现了与具有特定BSSID的WiFi网络的连接。

但是我遇到了一个问题：与特定BSSID的连接适用于安全网络但不适用于开放网络，我不知道为什么。事实上，这种与具有特定BSSID的开放网络的连接适用于三星Galaxy S4或更新，但不适用于Galaxy S2和S3 ...这真的很奇怪。在S2和S3上，在连接期间不考虑BSSID。

这是我用于为开放网络创建配置并尝试使用特定BSSID连接的示例代码：

    WifiConfiguration conf = new WifiConfiguration();
    conf.SSID = "\"" + wifiItem.getSSID() + "\"";
    conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
    WifiManager wifiManager = (WifiManager) parentActivity.getSystemService(Context.WIFI_SERVICE);

    wifiManager.addNetwork(conf);
    conf.BSSID = wifiItem.getBSSID();
    wifiManager.updateNetwork(conf);
    wifiManager.saveConfiguration();

    for (WifiConfiguration wifiConfiguration : wifiManager.getConfiguredNetworks()) {

        if (wifiConfiguration.SSID.equals("\"" + wifiItem.getSSID() + "\"")) {

            wifiManager.disconnect();
            wifiConfiguration.BSSID = wifiItem.getBSSID();
            wifiManager.updateNetwork(wifiConfiguration);
            wifiManager.enableNetwork(wifiConfiguration.networkId, true);
            wifiManager.reconnect();

        }

如果有人可以帮助我，那就太酷了。我花了很多时间在上面，真的不明白这个问题。

您可以尝试查看此代码，这是我们用于连接到网络的内容：

    private void connectToNetwork(String password, ScanResult result, String capabilities) {
    WifiConfiguration wc = new WifiConfiguration();
    wc.SSID = "\"" + result.SSID + "\"";

    wc.hiddenSSID = true;
    wc.status = WifiConfiguration.Status.ENABLED;

    if (capabilities.contains("WPA2")) {
        wc.preSharedKey = "\"" + password + "\"";
        wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_EAP);
        wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
    }

    if (capabilities.contains("WPA")) {
        wc.preSharedKey = "\"" + password + "\"";
        wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
        wc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
    }

    if (capabilities.contains("WEP")) {
        wc.wepKeys[0] = password;
        wc.wepTxKeyIndex = 0;
        wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
        wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
    }

    if (capabilities.contains("TKIP")) {
        wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
        wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
    }

    if (capabilities.contains("CCMP")) {
        wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
        wc.allowedKeyManagement.set(WifiConfiguration.PairwiseCipher.CCMP);
    }

    if (!hasWifiSecurity(capabilities)) {
        wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.NONE);
        wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
    }

    // wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.IEEE8021X);

    // // wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);
    // wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);

    int res = wifi.addNetwork(wc);
    Log.d("WifiPreference", "add Network returned " + res);
    boolean b = wifi.enableNetwork(res, true);
    Log.d("WifiPreference", "enableNetwork returned " + b);
    Log.d("", "Reassociate: " + wifi.reassociate());
    Log.d("", "ReConnect:   " + wifi.reconnect());
    wifi.saveConfiguration();

    WifiInfo connection = wifi.getConnectionInfo();
    if (connection != null) {
        if (connection.getSupplicantState().equals(SupplicantState.INACTIVE)) {
            wifi.removeNetwork(res);
            wifi.saveConfiguration();
            scanForWiFiNetworks();

            wifi.enableNetwork(wifi.getConnectionInfo().getNetworkId(), true);

        }
    }
    // scanForWiFiNetworks();

    // if (password.equalsIgnoreCase("")) {
    // setScanningEnabled(true);
    // }
    // Toast.makeText(con, "Connecting to network: " + connectionInfo, Toast.LENGTH_SHORT).show(getMessageComments(dialog.getTextID()));
}

我们需要使用与2.4G网络相同的SSID连接到5G网络，因此唯一的方法是设置BSSID。我刚刚使用下面的代码成功连接到几个指定的BSSID网络，请尝试：

WifiConfiguration config = new WifiConfiguration();
config.allowedAuthAlgorithms.clear();
config.allowedGroupCiphers.clear();
config.allowedKeyManagement.clear();
config.allowedPairwiseCiphers.clear();
config.allowedProtocols.clear();
config.SSID = "\"" + SSID + "\"";
config.BSSID = BSSID; // <--BSSID should be set without ->"<-  (-__-)b...

// remove this network from the configed(saved) network list
List<WifiConfiguration> existingConfigs = mWifiManager.getConfiguredNetworks();
for (WifiConfiguration existingConfig : existingConfigs)
{
    if (null != existingConfig && existingConfig.SSID.toString().equals("\"" + SSID + "\""))
    {
        mWifiManager.removeNetwork(existingConfig.networkId);
    }
}
config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);

//...
//...

// get the networkid 
int wcgID = mWifiManager.addNetwork(config);

// enabled this network
boolean b =  mWifiManager.enableNetwork(wcgID, true);

如何使用特定的bssid android连接到wifi？
