Answer 1

see the sample:

public static boolean isWifiEnabled() {
    if ( !gWifiManager.isWifiEnabled()) {

        if (mCanShowWifiToast) {
            new Thread(mWifiToastControl).start();
            G.gHandler.post(mNoWifiRunnable);
        }

        return false;
    } else {
        int linkspeed = gWifiManager.getConnectionInfo().getLinkSpeed();
        if (linkspeed < 5) {
            if (mCanShowWifiToast) {
                new Thread(mWifiToastControl).start();
                G.gHandler.post(mNoWifiRunnable);
            }

            return false;
        }
    }

    return true;
}
