Android6.0系统设置wifi修改保持连接了，但是偶尔会断开连接。查看log，发现如下内容：

04-09 15:09:27.569  2181 22861 D NetlinkSocketObserver: NeighborEvent{elapsedMs=2512360, 192.168.1.1, [(null)], RTM_NEWNEIGH, NUD_FAILED}

Adnroid6.0以上系统存在Android- IP LOST_PROVISIONING 的机制

可以在android\frameworks\opt\net\wifi\service\java\com\android\server\wifi\WifiStateMachine.java中屏蔽mIpReachabilityMonitor来解决。

            mIpReachabilityMonitor = null;
/*try {
                mIpReachabilityMonitor = new IpReachabilityMonitor(
                        mContext,
                        mInterfaceName,
                        new IpReachabilityMonitor.Callback() {
                            @Override
                            public void notifyLost(InetAddress ip, String logMsg) {
                                sendMessage(CMD_IP_REACHABILITY_LOST, logMsg);
                            }
                        });
            } catch (IllegalArgumentException e) {
                Log.wtf("Failed to create IpReachabilityMonitor", e);
            }*/
