# Network Troubleshooting - Internet Sharing

There will be times when troubleshooting requires you to eliminate the core network as a source of problems. This guide will walk you through how to create a mini test network using items you should have around the workplace.

***

## Initial Setup

{% stepper %}
{% step %}
**Set up your mobile hotspot so that your computer can connect to it. (Not covered in this guide, please refer to your owner’s manual for the specific device.)**
{% endstep %}

{% step %}
**Connect your computer to the hotspot.**
{% endstep %}

{% step %}
**Plug in the PoE injector and run one patch cable from the IN port to your computer. (We will wait to plug in the camera for now.)**

|                                     |               |
| ----------------------------------- | ------------- |
| Item                                | Number Needed |
| Mobile Hotspot                      | 1             |
| Laptop                              | 1             |
| PoE Injector                        | 1             |
| Short Patch Cable                   | 4             |
| Wireshark - Packet Capture software | 1             |
| {% endstep %}                       |               |
| {% endstepper %}                    |               |

## Set up for Apple Users 

{% stepper %}
{% step %}
**Select the Apple icon () in the top left of your computer screen.**
{% endstep %}

{% step %}
**Select System Settings.**
{% endstep %}

{% step %}
**In the search bar, type and select Sharing.**

<div align="left" data-with-frame="true"><img src="/files/ZsQgpJjB6jgmlOcqzA8y" alt=""></div>
{% endstep %}

{% step %}
**Select the info icon next to Internet Sharing.**

<div align="left" data-with-frame="true"><figure><img src="/files/xksf1JeRYNC5x72MDpvR" alt=""><figcaption></figcaption></figure></div>
{% endstep %}

{% step %}
**Next to "Share your connection from," select the interface connected to the mobile hotspot, then select the interface connected to the PoE injector’s IN port.**

In this example, the device connects to the hotspot over Wi-Fi, and the PoE injector connects through a USB Ethernet adapter plugged into the Mac’s USB-C port. The connection is then shared from Wi-Fi to USB 10/100/1000 LAN. (Your configuration may vary depending on your setup.)

<div align="left" data-with-frame="true"><figure><img src="/files/CDLYti2lkV0NFybGDwL4" alt=""><figcaption></figcaption></figure></div>

Click **Done** to continue.
{% endstep %}

{% step %}
**Back on the Sharing page, toggle on Internet Sharing. This will prompt you to start the sharing service. Click Turn on to start sharing.**
{% endstep %}

{% step %}
**Continue with** [**Packet captures - Wireshark**](#packet-captures-wireshark)**.**
{% endstep %}
{% endstepper %}

## Set up for Windows ⊞

{% stepper %}
{% step %}
**Press the Windows key ⊞ or click the search bar, type Control, and then select Control Panel.**
{% endstep %}

{% step %}
**Select Network and Internet.**

<div align="left" data-with-frame="true"><figure><img src="/files/h1pL3P6HcscDNatYJWM5" alt=""><figcaption></figcaption></figure></div>
{% endstep %}

{% step %}
**Select Network and Sharing Center.**

<div align="left" data-with-frame="true"><figure><img src="/files/S69NGUBlYqkxeQ6oV3KZ" alt=""><figcaption></figcaption></figure></div>
{% endstep %}

{% step %}
**Select Change adapter settings.**

<div align="left" data-with-frame="true"><figure><img src="/files/ReCMMIPPmm4hy49G0hAo" alt=""><figcaption></figcaption></figure></div>
{% endstep %}

{% step %}
**Find the interface that is connected to the hotspot. Right-click it and select properties. In my setup, I have connected to my hotspot via WiFi.**

<div align="left" data-with-frame="true"><img src="/files/zMypOe8sDjrJYCgJiY7R" alt=""></div>
{% endstep %}

{% step %}
**Select the Sharing tab and check the box next to Allow other network users to connect.**
{% endstep %}

{% step %}
**Select the interface you wish to share the connection with. This will be the port of the PoE injector’s IN cable. In my case, it is Ethernet. Once the interface is selected, click OK to start sharing.**

<div align="left" data-with-frame="true"><figure><img src="/files/Sq1g4q6dad0MmOzaPj7I" alt=""><figcaption></figcaption></figure></div>
{% endstep %}

{% step %}
**Continue with** [**Packet captures - Wireshark**](#packet-captures-wireshark)**.**

## Packet Captures - Wireshark

Verkada Support’s tool of choice for getting packet captures is [Wireshark](https://www.wireshark.org/). Wireshark is an open-source packet capture/analyzer program. We will use it to create a .pcap file to send to the Verkada Support team.

{% stepper %}
{% step %}
**Download and install** [**Wireshark**](https://www.wireshark.org/)**.**
{% endstep %}

{% step %}
**Open Wireshark and select the interface that your PoE injector is connected to. In my setup, `USB 10/100/1000 LAN: en12` this is where my Poe injector’s IN cable is connected. This will allow us to capture and see the traffic passing to and from the camera.**

<div align="left" data-with-frame="true"><img src="/files/sEEo8edXJXAlT0X4khKZ" alt="" width="1023"></div>
{% endstep %}

{% step %}
**In the top left, select the blue shark fin to start the packet capture.**
{% endstep %}

{% step %}
**Plug the camera into the OUT port of your PoE injector. Only&#x20;*****after*****&#x20;you start the packet capture plug in the camera. You will see the packets start to flow. (This could take a few moments as the camera needs to go through the boot process.)**

<div align="left" data-with-frame="true"><img src="/files/L2jJ8gQDGhF2DKMomnuE" alt="" width="743"></div>
{% endstep %}

{% step %}
**Wait five minutes, or until the camera’s LED status light turns solid blue, then select the stop button (red square).**
{% endstep %}

{% step %}
**Save the file and share it with Verkada Support for assistance in troubleshooting.**

{% hint style="warning" %}
If your camera was not connecting on your core network but successfully connected to Command using your mobile setup, this tells us that the issue lies somewhere on the core network.
{% endhint %}
{% endstep %}
{% endstepper %}
