<h3>I. Problem Phenomenon</h3>
<ul>
<li>
<h4>Client cannot display the device is online</h4>
</li>
</ul>
<p>Devices with networking capabilities.
1、If using WIFI, and all parameters of WIFI have been set, and the WIFI antenna is connected normally.
2, If using 4G, and SIM card has been inserted, antenna connection is normal.
3、The central parameters and registration parameters have been set.
However, it is not possible to show the device online on the client, and it is not possible to control the device. The CMSV6 shows a status similar to the following figure.</p>

<h3>II. Analysis Steps</h3>
<p>You can follow these steps to troubleshoot the causes of the problem one by one:
1, Using WIFI devices, check the working status of WIFI, whether the conditions of networking.
2, Using 4G devices, check the working status of 4G, whether the conditions of networking are available.
3, Check the parameters of the device, check whether the center parameters, registration parameters, etc. are set correctly.
4, Check the information of the device added to the platform, and check whether the device number and other information is correct.
5, Restart the CMSV6 to check whether the client display problems.</p>
<h3>III. Operating Instruction</h3>
<h4>1、Check WIFI Network Status</h4>
<p><strong>1.1 Checking device connection hotspot status</strong>
In the DEVICE STATE page, check the status of the WIFI network.</p>
<pre><code>-- Check whether the module status shows exist, if not, then you need to check whether the enable is on. the module keeps showing non-exist under the condition that the switch is on, then there may be hardware failure.
-- Check whether the SSID is successfully connected, if not, you need to check whether the set hotspot parameters are correct.
-- Check the signal value, if the signal value is low, you need to check the antenna status, and check the distance between the device and the hotspot, and the obstacles, etc.
-- If the hotspot is successfully connected, the assigned IP address will be displayed, and if the address cannot be displayed, the network cannot be connected.</code></pre>

<p><strong>1.2 Check the hotspot network and server network connection status</strong>
If the previous section has shown that the connection to the hotspot is successful and you still cannot get online, you can check the network where the hotspot is located to see if it is connectable to the network where the server is located.</p>
<pre><code>-- Using a device, such as a computer, to connect to a hotspot.
-- After successful connection, the address or domain name of the ping server to confirm whether it can be connected, if not, you need to investigate the reason from the network level. If it is passable, it means that there is no problem with the underlying network and continue to the next step of troubleshooting.</code></pre>

<h4>2、Check 4G Network Status</h4>
<p><strong>2.1 Check device dialing status</strong>
View in the DEVICE STATE-Module interface, provided that dial-up enable is turned on.</p>

<p><strong>2.2 Check SIM card traffic status</strong>
Check it by yourself in the cell phone business hall.</p>
<p><strong>2.3 Check the connection status between the network where the SIM card is located and the network where the server is located</strong></p>
<h4>3, check the on-line parameters of the device</h4>
<p><strong>3.1 Check device registration parameters</strong></p>
<p><strong>3.2 Check device center protocol parameters</strong></p>
<p><strong>3.3 Check device center IP and port</strong></p>

<h4>4, Check the device information of the platform</h4>
<ul>
<li><strong>Check the information of the devices added to the platform</strong></li>
</ul>
